Mrs Cecil (Basingstoke, April 2024) Thank you so much to you and Anna for coming out last week. A familiar story of blocked micropore pipes with some stone cold radiators and some poorly working ones slowly getting worse over the years. Our plumbers had put a cleaner in the system and then suggested re piping the rooms that were affected. I found Powder Flush on line and it was easy to book a convenient date. You and Anna worked hard all day to clear the pipes and all the radiators are now working ( hot like larva!) and the ones we thought were Ok are now even hotter. Our old pump was replaced and a Magnaclean fitted to prevent further build up and you weren’t phased by our 22 year old oil boiler. Cannot thank you enough, you have saved us expense and upheaval and we now have a warm house. We have no hesitation recommending Powder Flush and will be spreading the word.

Mr Heath (Sandhurst, April 2024) Hi Morning I can say that the heating has never worked as good as it is now, the boiler now working at a lower temperature. The service work was carried out so with no mess and and a credit to the both of the engineers.

Mr Noun (Kensington, March 2024) Our System was clogged up some radiators works and some don’t. Got in touch with powder flush.

They did magic on our system all radiators are running as should be. Many thanks to Stephen & Anna our heating is back to normal. Keep up the good work guys.

Mrs Jebb (Bromley, March 2024) Hi Stephen!!….And yes thank you!…the heating is working great now!…so I would definitely recommend that people get this done!!……

Mr Watson (Thame, March 2024) Thanks for your help to fix our heating problem - it's like having a new system! It's made a real difference throughout the house, particularly downstairs and we couldn't be happier. The service was good; you turned up within the appointed time, took care to ensure nothing was damaged by laying down dust sheets, etc and kept me informed of progress throughout the day. I would definitely recommend Powderflush to others, particularly with microbore pipe.

Mr Bell (East Molesey, March 2024) The service was impeccable and the results have been incredible, so much so that we now have to turn the heating down. Two new radiators in the house never used to get much warmer than luke warm, now they are too hot to touch. The team was extremely professional and considerate. I highly recommend Powder Flush.

Mr Hunter (Bicester, March 2024) I had an issue with my micro bore heating system that was slowly getting worse annually until this year when the radiators struggled to output sufficient heat and others no heat at all and getting intermittent flow faults on my boiler. I suspected that a power flush would be required and researched this online but not a lot of joy on flushing on my system until I came across “ microbore guru “. This led me to the powDerflush website and after reading reviews I booked a visit as I reckoned this process having watched the short descriptive videos would be more beneficial for me. The powDerflush team of Stephen and Anna arrived on time and got to work. The equipment was brought in and protective sheets as needed. They methodically diagnosed and cleared my system using the unique powDerflush process and the heating has been transformed. Polite, professional and I would not hesitate to recommend them to anyone with failing heat systems. Superb.

Mr Rice (Leonards On Sea, February 2024) My microbore heating/hot water system had been getting slowly less efficient. My plumber fitted a new pump in an effort to improve it without success. He suggested it may be time for a new system as this one was quite blocked. After discussion it was suggested that powder flushing would be worth a try.

Stephen and Anna arrived to undertake the task, They set to work soon after arrival and continued to work solidly for the next 4 to 5 hours. After flushing the system right through and replacing one small length of pipe that was completely blocked they had the whole system up and running. The success of this flushing was astounding. My radiators were running hotter than they had done for years and there was no drop in temperature when the water heater was on at the same time.

Stephen and Anna carried out this work in a most efficient manner without any mess at all. Due to problems before arriving at my home they were somewhat late starting, but despite that they worked on into the early evening until the job was completed.

Having this work done has saved me a very expensive outlay on a new heating system. The work was carried out expertly and with a fantastic result. I wouldn't hesitate in recommending Powder Flush Ltd. Thank you Stephen and Anna

Mr & Mrs Till (Southfleet, January 2024) Our Microbore heating system of approximately 25years, has never worked so well since your visit in January 2024 . The property now achieves an even temperature throughout, all 9 No radiators and 1 kick space heater are now functioning properly. The operation of Powder Flushing was very professionally undertaken in one day as planned, without any mess or damage to the fabric of our home.

We would have no problem in recommending Powder Flush Ltd to anybody with a blocked heating system, before they embark on any costly destructive or replacement remedial measures.

Mr Game (Enfield, January 2024)  We have been struggling for years with cold radiators in our house. Many plumbers and heating engineers have failed. Due to the plastic micro-bore pipes most refused to even look at our heating system and one said we had to spend £15,000 to replace the pipes and boiler. Stephen and the Powder Flus was my last chance to save our system from the skip! Stephen was extremely knowledgeable and professional and was able to get all our radiators working normally. I was amazed and very appreciative of his skills and abilities. I suspect that Stephen is the only person in the UK that could have fixed our radiators.

Mr Pollard (Peterborough, January 2024) Many thanks to you and Anna for a hard day’s work on our heating system. The system is now quiet for the first time in years and the lounge radiator now gets hot again! We would recommend you both for keeping us informed, arriving as expected and clearing up when you had completed the job. A job well done!

Mr Patel (Wembley, January 2024)

All our radiators upstairs stopped heating up suddenly. The central heating pump and 3 port diverter valve were changed and still the same problem existed. After trying various attempts to resolve the problem I concluded that it had to be blockage somewhere. After searching on the internet for Power Flushing companies, I stumbled upon POWDER Flush and am I glad I did. I researched more on the website about the Powder Flushing process and I felt that this was more suited to my situation. I booked an appointment online and was allocated a day for the repairs. On the day, Stephen and Anna turned up on time and after showing them my boiler and airing cabinet, they laid down dust sheets and towels on the floor and began to bring in their equipment. They worked hard for 6 hours and managed to clear the blockage on my 40+ year old conventional central heating system. I was surprised to see the rust particles and sludge that was flushed out. All the heaters are heating up better than before and the boiler has stopped making noises. Thank you very much for your professional service and getting our central heating system up and running as it should be. I will definitely recommend your services to family and friends. 

Mr Etheridge (Swanley, January 2024) My problem was a familiar one. Over many years we had experienced many problems with our central heating system. The radiators were very slow to heat up with some patchy and some not heating up at all . Two years ago we had a new boiler fitted but it didn’t help. Last year we had our boiler serviced and was recommended a power flush because of sludge and filthy water . We was hoping that this would be the solution, however the engineers were unable to perform this due to low flow. They abandoned me in a worse state than when they started as the cleaning agent used prior to the flush had dislodged more rubbish in the pipes. I looked on line and discovered Powder Flush. I thought, what have I got to lose so I booked them. Stephen and Anna arrived and got to work straight away. Within a couple of hours he told me just how blocked our system was, 80% blocked upstairs and 97% blocked downstairs. By mid to late afternoon the heating was back on and everything was clear. All of our radiators are now hotter than I have ever known them.

If you are in the same situation as me I wouldn’t hesitate to recommend Powder Flush!!

Mrs Washer (Lewes, East Sussex, December 2023) I can only say thank you! I only know I had neither heating or hot water for nearly four weeks - and then you came in and worked miracles..I now have heating and hot water working better than ever before - so thank you so much for your expertise.

Mr Barret (Brighton, December 2023) We would just like to say thank you so much for fixing our heating system which is now working very well. Having had many months, if not years, of an old inefficient system we wish we had known about Powder Flush before. The radiators and hot water are hotter than we can remember and we would thoroughly recommend your service.

Thanks again and wishing you a Happy New Year

Mr Challenor (Luton, November 2023) We are very pleased with the results of Powder Flushing our central heating system. We had three problematic radiators – two getting only warm and one not getting any heat at all. After the treatment these rads are working perfectly and we feel that the others are working more effectively also.

The work was carried out in a very efficient and careful manner with no mess. It took about 6 hours. Your people arrived on time and worked solidly throughout. Thanks very much for a job well done.

Mr Bellamy (Harrogate, November 2023) The heating company I use recommended this company due to the 10mm plastic pipes being partially blocked. After the initial briefing, Stephen and Anna methodically commenced work. Great care was taken in protecting my furnishings and they cleaned up afterwards. I now have a heating system that works as efficiently as a new system. This company is very highly recommended.

Mr & Mrs Marsden (Essex, November 2023) The previous plumbers had done a power flush but the final 3 rads in the system wouldn’t heat up. We were very reluctant to lift the lovely oak flooring to try and solve the problem.

Powder flush were recommended and we decided to give them ago. Wow! They arrived with lots of kit and set to work.

A few hours later our whole system is pumping hot! We have turned the stat down as all the rads are now so efficient. A big black bucket of sludge was removed and our floorboards didn’t have to be touched! Highly recommended.

Mr Clifford (Peterborough, October 2023) Thank you for your email. System is working well now and our lounge is lovely and warm. The stat is actually getting to temperature now and controlling the boiler which will I am sure make our upstairs area cooler and our gas bill lower as the downstairs of the house is now being heated correctly. I have contacted our heating engineer to look at the works you advise on. Hopefully once the larger pump etc is fitted the system will prove even more efficient. Thanks for your help and professionalism. I will definitely pass your details to others with blocked heating/similar problems with their heating systems.

Mrs Beaney (Chardhurts, October 2023) Hello Stephen, the heating is the best it has ever been, the house is wonderfully warm, and this is all because of the fantastic job you did. I found you and your colleague to be efficient, thorough, extremely tidy and always courteous 

Thank you so much

Mr Pichon (Herts, September 2023) Hi Stephen, I'm only too pleased to give Powder Flush a glowing testimonial. We had previously tried two separate central heating companies, who both failed to unblock our radiators. We were told we had three radiators blocked and the only solution would be to re-pipe the system with all the disruption throughout the house. My neighbour recommended Powder Flush and it was the best decision I could have made. Stephen found not three but nine radiators not working efficiently, worked solidly till 6.30pm but cleared the system successfully. If only I had found Powder Flush earlier. A warm house efficiently heated beckons, thanks to Powder Flush.

Mrs Gini (Guildford GU15, August 2023) Hi Stephen, so happy with how hot the water is, can’t keep out of the shower. The radiators have never been so hot, but as it’s August only had a quick check. Would so recommend the work you have done. So I say Thank you. Sandy

Mrs Rayment (Hemel Hempstead HP3, July 2023) Before Powder Flush came to our rescue, our upstairs radiators were red hot and our downstairs radiators were barely lukewarm. By the time they left, all our radiators were scorching! We had been told our system was full of sludge and were advised to try powder flushing in preference to the normal power flush. Stephen and Anna were very professional and took great precautions to cover everything over and cleaned the bathroom up after they had finished. I wouldn't hesitate to recommend them. Francesca.

Mr Porter (Emsworth PO10, February 2023) We moved into our house during a very cold spell in February 2023. There was no heating and from day one the system was not working . We could get some hot water, but the heating radiators were either cold or at best lukewarm. We called a heating engineer who when he came several days later was unable to get the system working. The work he did made no improvement and he was scratching his head as to what to do next. He thought the problem might be that the system was blocked with sludge etc. He said the system had already been power flushed and that this had probably not worked. So, he suggested we contact Powder Flush as this was a system he had used previously in similar circumstances.

Powder Flush were able to come promptly, and I am pleased to say that they had the system operating once they had completed their work. Looking at as cross section of one of the heating pipes it was little wonder that the system wasn’t working. It was almost completely blocked with sludge which the Powder Flush method was able to shift.

Powder Flush were very easy to accommodate in the house particularly as we were still unpacking. They were very efficient, clean, and tidy.

We highly recommend them

Mr Muid (London TW12, February 2023) We had 5 of 12 radiators stop working. We were advised by British Gas that as it was a system with microbore pipes they could not be flushed out. They told us to have new pipe work fitted. We saw PowderFlush advertised on the internet and contacted them. Stephen and Anna from PowderFlush spent 9 hours clearing our CH system, tackling one particularly troublesome stubborn radiator with determination. They succeeded and our system is now working fully and better than it has for many years. I recommend them highly to anyone who has microbore pipes and facing a similar situation.

Ross (Melton Mowbray LE13, February 2023)

Excellent.We're very pleased with the outcome and we feel the PowderFlush process represented excellent value for money - cheaper than a new boiler. Your employees arrived on time, were courteous, explained what was to happen, and cleared up after them with no mess and minimal inconvenience. We don't hesitate to recommend you.Thank you.

Mrs Woodland (Leicester LE7, January 2023) It is now a couple of weeks since Stephen and Anna arrived on time at 10.00am with their box of tricks and after several hours of flushing my totally blocked rads, worked their magic on my 8 radiator microbore system. I have lived in the property for 30 years and the heating has never been so efficient. After being told that a new boiler and possibly radiators were required, the Powder Flush treatment has actually saved me many thousands of pounds. It is just wonderful to be so toasty in all rooms, I wouldn't hesitate recommending anyone with heating problems caused by blockages to give it a try. I'm absolutely delighted that I have.

Mr ONeil (Loughton IG10, December 2022) Thank you for powderflushing our central heating system last week.Our heating has never worked so well since we have all radiators working and complete flow around the system.I can totally recommend powderflushing.co.uk as they really went that extra mile to get my heating working again not only did they powderflush the system but also had to cut out a two foot section of pipe that had become totally blocked and restore flow to the boiler.Thank you once again

Mr Gasparro (London N15, December 2022) Couldn’t be any more happier with the central heating system at my parents house, I’m glad I found you guys on YouTube through Allan Hart‘s channel, just got on with the job, thanks again.

Mr Lampen (Chiseldon SN4, November 2022) Thanks for your email Stephen. As a testimonial l would like to thank you for your hard work on the day and leaving our house in a clean and tidy state - remarkable with the amount of kit you were using! The system is massively improved from the work you carried out and the radiators are now hotter than they have ever been. Many thanks.

Mr Leo (Bicester OX26, November 2022) Thanks so much for your hard work on Sunday.

We were really stressed when our central heating system blocked up and stopped working, especially as the heating engineer’s recommendation was to replace the existing (old but fully functional and recently serviced) back boiler with a combi-boiler and replace the blocked microbore pipework with new standard pipework throughout. However, the heating engineer did tell us about Powder Flush and said that it may be an option instead of fully replacing the system.

We opted for the no fix no fee option with Powder Flush and are really glad we did, as not only did you manage to clear a huge amount of crud from the pipes you also balanced the system correctly, adjusted flow rates to all radiators and the hot water feed and set the pump to the correct speed for our system.

No one has ever explained how our central heating system worked as clearly as you did.

I believe that our heating problems were essentially caused by an open vented system, old rusty radiators (which were replaced a couple of years ago) and a build-up of crud following a previous power flush in 2019.

When booking the power flush I did see Powder Flush as an alternative, but didn’t choose this due to the cost difference. In hindsight I wish I had gone straight for the Powder Flush as the power flush didn’t work and I may have avoided a few unpleasantly cold winters and saved myself quite a lot of inefficient gas consumption!

Our central heating is working really efficiently now.

Thanks again.

Mr Swinburn (Welwyn AL6, November 2022) A sincere thank you to the Powderflush team for their fantastic work!

A quick summary below of the problems we had with our heating system, and how the Powderflush team were able to assist us.

Our heating system has 11 radiators on two floors, connected via copper microbore to a Worcester gas boiler. Because of blockages in our heating system we had no hot water to our radiators or hot taps.

Lengthy traditional power flushing by our plumber couldn't remove the blockages. The boiler heat exchanger was blocked; it appears one or more of our radiators was de-laminating.

We had our old radiators removed and the heat exchanger replaced, then booked Powderflush to clean the heating system.

Powderflush found sediment and blockages throughout the system, but after 5 hours work all blockages and sediment were removed.

Our plumber installed new radiators and was pleased to find that we now have good flow across the entire heating system, with clear water and no sediment. We are delighted to have hot water and heating again, throughout the house.

Thanks again for your assistance.

Mrs Berlyn (London, EN4, November 2022) We are very pleased with the outcome of the powder flush. All our radiators are now working, and we have a lovely warm home!

I appreciate you fitting us in earlier than originally planned, especially as the weather has taken a turn for the worse!

Many thanks

Mrs Parratt (Leeds LS14, October 2022)

Hi Stephen,

The heating is working brilliantly now, it’s great to have the whole house warm again, thank you.

Further thanks for putting up with our crazy heating system!

Mr Heal (Winchester SO22, June 2022) Hello Stephen, the system works incredibly well - many thanks for your work. The hot water cylinder heats up very quickly now. Many thanks.

Mr Davies (Essex CM9. April 2022). Hi Stephen, Powder Flush successfully cleared our central heating pipes of an accretion of sediment that had been restricting flow to several radiators causing flow problems for several years. The system is now operating properly with hot radiators in every room and a much quieter boiler. I have also been able to turn down the pump speed and save some electricity! Many thanks for a good job

Mr Alvarez (Bloxham OX15. March 2022). I had real problems with blocked pipe work and radiators, the heating system had ground to a halt. Five radiators downstairs stone cold for years. Had boiler serviced and the system checked by other companies. Some recommendations and advise ridiculously expensive and no guaranties of success.  After research, the Powder Flush seemed a good option to try, and the option of “no fix, no fee” was very reasonable . Stephen and Ana turned up spot on at the time they said they’ll be here. They spent the whole day working around my 11 radiators, replaced the pump and 3 way valve. They didn’t even stop for luch, and they didn’t leave until the system was working perfectly. Incredibly they didn’t make any mess; I think my house was cleaner when they left than when they arrived. They were very polite and respectful, and all I can say is a massive thank you, I have a working heating system again and more heat than I can remember. Well worth every penny, cannot not recommend this enough, and I will do so at every opportunity.

Thank you.

Ms. Cooper (Worthing, BN13, February 2022)  We are so happy with what you have done for us. The gas central heating has been working brilliantly since you left and we have noticed a remarkable difference in our heating level in our home- especially in the evenings.

We are also so thankful that the banging has stopped in the ceiling and we are so delighted that you have solved the banging problem and poor flow efficiency to the radiators and for replacing the three port valve, and all the extra bits you did for us were also very much appreciated. Christine has left some comments on Allen’s YouTube videos to testify of your work and it’s effectiveness in improving the efficiency of our gas heating system and the great service you provided whilst you were here. We cannot fault your service at all and we will be recommending your service to others, and Christine has made a recommendation on Nextdoor app which is a neighbourhood social media facility that helps spread the word about businesses, so she put a good recommendation for Powder Flushing and it’s ability to significantly improve gas central heating systems.

Thank you also for the advice you gave regarding the filter for the rust to be cleaned out every couple of years and we thank you for doing that when you visited, you clearly go the extra mile in your service and it’s very much appreciated, and thank you for the extra two way pipework as well that you put in in the loft area and the improved connection pipework in the main cupboard.

Yesterday evening was quite a chilly one so we definitely noticed the heating was much better and we appreciated having the heating working well so we could have a nice warm bungalow to watch tv etc and without us needing to use electrical heating appliances or the gas fire to boost the heat level. Therefore our bills are going to be a lot less now and you’ve probably saved us from having to replace the boiler or the whole central heating system if it had continued to go on with this problem.

Thank you very much to you and Anna and it was nice to have you both here, and you were very respectful of our home environment as we didn’t feel we had too much disruption, even our cat was comfortable with you both here so that was impressive, thank you.

Mr. Watkins (Eastbourne, BN22, January 2022) Having spent a lot of money with heating engineers and power flushes to get our downstairs heating to work, we had nearly given up as these were not successful.

One very cold day in December, I was talking to our kitchen fitter and he mentioned that a previous client of his had had a Powder Flush done and that he had heating for the first time in many years. I googled it and noticed that there is a no fix no fee price which for us was a very good option as no one had been able to get five radiators downstairs to work so we have had no heating for at least 10b years. Stephen worked with minimal disruption and was at the house from 10am until 4.30pm and what can I say, our downstairs radiators now get red hot and this had transformed my life in the cold months.

Mr. Cross (Tadley, RG26, January 2022) I was introduced to your company by our plumber who found you on the internet as our pipes in our rented house was really bad and needed a flush. Our plumber did a standard flush that just made things worse.

First of all being able to book online was really good. Stephen came out and texted regarding the job with prices once he had inspected. I went with the fixed price and within a few hours had another text to say it was all sorted and my tenants had heating again after 2 weeks of none. So it was super quick and slick and I would highly recommend this service to anyone. I certainly will be calling when I move house to make sure my system never has a problem. Thank you so much for the quick and easy service.

Mr. Farren (Camberley, GU16, December 2021) Hi! A week later and everything is still working properly.

In fact better, far better than it's ever worked before. It was a lot of money, but it was worth it- no hesitation whatsoever in

recommending PowderFlush. Totally effective, didn't make a mess andgot the job done quickly. 

What's not to like?

Mr. Hands (Harpenden, AL5, November 2021) Our heating system has never really worked since we moved into the house 9 years ago. We have had the boiler replaced, the tank replaced, pump replaced (twice), radiators flushed, the list goes on. But the house never got warm, and it had got steadily worse to the point where we could only have half of the radiators on, the water heating hardly worked, and one radiator was completely dead.

I was recommended the powder flush process by a heating engineer who could not fix the dead radiator. He said it was expensive, but a much better process than a normal power flush. I must admit that I did think very hard about this (I am naturally stingy 😋), but decided in the end that I needed the best chance of getting the system working.

I am so glad that I did! We now have a fully working system, all radiators fully working and very hot. The heating system easily heats the house up, even when it is below zero outside. I also have a whisper quiet pump rather than one that sounds like an old tractor. Powder flush has completely transformed our house - it is a revelation!

I also would like to mention the quality of the service. The team turned up exactly on time, instilling me with great confidence right from the start. After a 15 minute question and answer session, they got to work and were respectful and professional throughout the very long day they were here. They were very clean and left no mess. These are top professionals at work.

Mr. Wojcik (Chicester, PO19, November 2021) Clare and I were extremely impressed with the work you undertook which has completely cured our problems. Our 46 year old central heating now performs like a new system! It is now incredibly quiet and all our radiators reach a high temperature really quickly. Domestic hot water likewise is working efficiently. We were so grateful for your eight hours hard work and for leaving everything tidy. Thanks again. 

Mr. Cook (London, N15, October 2021) The microbore heating was now only working on 3 radiators and a major gas heating firm suggested Powder Flush. Booked an appointment which was easy to do. The team arrived on time and lost no time in getting started, at each part of the process I was kept informed, wow what a team. I was shown how bad the system had got almost to the point of completely blocking off. The process took the whole day, and yes, the initial outlay sounds like a lot but wow I have now got a heating system that is efficient and takes minutes to heat up. I would recommend Powder Flush to anyone who has microbore troubles.

Mr. Southern (Royal Tunbridge Wells, TN1, September 2021)Thanks for the service, we are very impressed and now have all the radiators heating perfectly. The Powderflush has particularly transformed our lounge, which was very cold due to the two radiators not working correctly. Very thorough and efficient service, we would definitely recommend to anyone contemplating having their system cleaned.

Mr. Collet (Cambridge, CB24, May 2021) My system was slowly shutting down; first 1 radiator then another and then another would not even get warm. We had the system power flushed and it helped but 1 radiator was just stone cold.

We replaced the radiator and had another flush – still the same and the plumber said I would have to replace the pipes (which run under a concrete floor). This meant taking up the carpets and being without heating for several weeks – so I left it and used a fan heater in that room. This winter it got so bad that the boiler was banging and so were the pipes.

Every morning the boiler would wake me up banging – I didn’t need an alarm clock. I did a lot of research and found Powderflush and booked them for a flush. They were here from 10 in the morning until 7pm at night (Stephen said that the system was really bad). When they were finished every rad in the house was hot and the boiler was silent. 

One week on and it’s like living in a different house. Everywhere is warm and the boiler is so quiet!

Powder flush are more expensive than a power flush – but I would spend the money – it’s much cheaper than replacing pipework.

Mrs. Stanford (Hampshire, RG24, April 2021) Thank you so much for ‘Powder Flushing ‘ our central heating system last week. We were amazed to see that you removed 6KG of old rust/gunk and also how the pipes had become so blocked that only a small aperture was left free flowing. In the 15 years that we have lived in our house it has never felt so warm with all our radiators now feeling hot all over. We were so impressed with your professionalism and how clean and tidy you left everything after you had finished.

Our usual plumber/central heating engineer recommended your services and we would have no hesitation in recommending ‘Powder Flushing’.

Mr. Sagar (Chipping Campden, GL55, February 2021) Thank you for a very professional job, Our system which was a mixture of plastic, copper & micro bore it,did not work efficiently & had a blocked radiator . You solved the problem others had failed to do.. Thank you for the ease of booking, arriving on time & spending the whole day working on the system with no mess. We now have a fully functioning central heating system & all radiators working. It’s more efficient, we have been able to reduce the temperature setting on the individual radiators. I have no reservations in recommending your system.

Mr. Furniss (Gloucester, GL2, January 2021) We contacted PowderFlush after our plumber was unable to locate a blockage that had rendered seven radiators unusable. The only other option was to have pipes removed and new piping installed which would have been very disruptive and time consuming. Powder flush arrived on time at 10am and set to work straight away. After a full day flushing the system they left at 7.30pm and we are very pleased with the results . Radiators that had not worked for quite some time now work beautifully and the only one that didn’t respond to flushing on the day is now slowly coming back to life .

We would definitely use Powder Flush again if we ever find ourselves with a central heating system that was not working due to a blockage that could not be located . I wouldn’t hesitate to recommend their services others .

Mr. Worthington (Boston, PE21, January 2021) Thanks Steohen for your work on our blocked central heating. I have worked in the building industry for nearly forty years and am not easily impressed. But your system and the service you provided really impressed. Our heating engineer had tried everything he knew to clear the system but no amount of standard flushing would solve it. The powder flush worked fantastically well so we have gone from very little heat to red hot radiators.

Ms. Jones (Gloucestershire, GL16, December 2020) Having had constantly blocked radiators for years, the gas board have almost given up on trying to unblock them, and are at the point of refusing to even try, after 20 yrs of paying for a full maintenance service. The plastic micro bore pipes are so easy to block, and the generation of thick tar-like sludge in the system is immense. Stephen’s Powder Flush system has been miraculous. He was able to remove more than 2kg of sludge, and ALL 24 radiators are now running red hot and wonderful! He said we were very close to a total system blockage. So if you have plastic pipes and having blockage problems, don’t hesitate to call in Stephen. I wholeheartedly recommend this powder flush process.

Mr. Bateman (Arundel, BN18, West Sussex, November 2020) Our system was a mixture of plastic and copper pipes and the radiator in the bathroom had not worked for many years despite numerous plumbers taking a look. It was one of these plumbers that recommended Powder Flush to us. Booking an appointment was easy and Powder Flush arrived on time. After a long day, the job was done, the system gets to temperature with no difficulty and the bathroom radiator now works. Powder Flush were very professional and there was no mess involved. Thank you! 

Mr. Graham (Northampton, NN6, October 2020) Many thanks guys, you turned a central heating system with 17 radiators of varying sizes types and heating output into a consolidated efficient unit. Our house now has warm controllable heat which is as good as it gets.

Mr Brown (Ipswich, Suffolk, July 2020) - System:19 radiators on white plastic microbore pipes, with 4 not working correctly - Thank you for fixing my system last week. The system seems to be working really well indeed. Result: All radiators work correctly after the Powder Flush.

Mr. Ryan (Ealing, London, W5, March 2020) – System: Normally sized pipes, 8 radiators Problem: 4 radiators not heating, power flushing has already failed, recommended replacing pipes – I am a plumber with over 40 years’ experience. I have never used Powder Flush before, it was always power flushing for me, but on this occasion power flushing failed. I contracted Powder Flush, who got the whole system back to full power again. The team that came out was very polite and professional, I can’t recommend them enough. I think from now on I will just Powder Flush over trying to power flushing.

Mr. Murphy (Tunbridge wells, TN2, March 2020) – System: Copper microbore, 13 radiators Problem: 2 radiators did not work, one has not worked in 10 years, recommended pipe replacement – Thank you very much and I appreciate how you professionally dealt with what I thought was a major problem.

Mr. Painter (Guildford, GU4, March 2020) – System: Copper microbore, 7 radiators Problem: Client bought a house, after moved in tried the heating system. House not getting to temperature, boiler banging, 1 radiators completely dead and rest only gets luke warm – I am amazed at the results, I wasn’t confident it’d fix it though it completely has, so thank you! It’s a huge weight of our shoulders having recently moved into a house with such a severe heating issue, as you can imagine! Really appreciate your expertise – you’re very knowledgeable in the area, thank you for answering my questions and passing on the relevant bits going forward also. I recommended you to my in-laws for their issues with their underfloor heating. Thanks!

Mr. Phelps (Cardiff, Wales, February 2020) – System: Plastic microbore pipes, 14 radiators Problem: 6 radiators do not heat correctly – Our heating system never came up to temperature. There is a mixture of copper and plastic microbe which British Gas will not touch. Powder Flush worked from 10am to 9pm and got all but one radiator working. The rest of the system and the house now gets to temperature with no difficulty. It has stayed nice and warm ever since. I am very grateful for the hard and professional work Powder Flush did, with no mess.

Mr Lampert (Watford, December 2019) - System: normally sized pipes, 22 radiators Problem: 2 do not work - Just wanted to say what a professional and effective job you did in flushing out my central heating system. I appreciate that we had a large system with three pumps. After what seemed like a long day the system worked perfectly. I was also highly impressed with Stephen's knowledge and experience and despite being more expensive that traditional power flushing systems I would highly recommend it.

Mr & Mrs Hanson (Middlesex, December 2019) - System: plastic microbore, 9 radiators Problem: 3 radiators do not work - We wish to thank you so much fir the super service you gave us with the Powder Flush. Now that the weather has changed it has come into its own and it's working so much better. We can turn it down instead of up! It has made our lives so much better.

Ms. Joyce-Allen (Littlehampton, November 2019) - System: copper microbore, 9 radiators Problem: 2 radiators do not work at all, system slow to heat, house not hot enough. Powderflush has transformed how I can enjoy my home in the cold months of the winter, as much as in the summer. I moved into my house 6 years ago but found that I needed to use electric radiators in the colder months. Forcing me to live in the small corners of the house. I was informed that the microbore piping was blocked by several plumbing companies, but they did not return my calls to fix the problem. I found Powder Flush online and saw the video of how it would resolve my problem. The team of two, did the work in one day. The result, instant wonderful heat with nine radiators fully functioning.

Mr. Fundak (Coventry, October 2019) -System: 7 radiators copper microbore pipes Problem: Boiler locks out/stops working with f23 and f25 code. Client took No Fix No Fee option - Thank you for your recent visit to fix my clogged-up micro-bore plumbing system, which had not worked properly for several years. I'd more or less given up with it, and was seriously considering re-plumbing the whole house or going electric. Powder Flush was the final attempt to clear the system and I wasn't particularly optimistic. Powder Flush turned up exactly on time and were very professional, skilled and efficient in setting up and carrying out the procedure. They successfully fixed the problem and I was very impressed and grateful for an excellent job and will recommend them in future.

Mr. Skidmore (St. Albans, September 2019) - System: 9 Radiators, normal sized pipes, 2 radiators on plastic pipes. Problem: System not heating fully/correctly - We have been very pleased with the work done by Powder Flush. For many years we had a problem with the two radiators in the extension of the house and at the end of the circuit. Even when other radiators worked "OK" they never got as hot as they should have done. Even replacing the radiators with larger ones made very little difference. Our heating engineer said it might be worth a tying Powder Flush because he had heard it solved problems that nobody else could solve. It took them most of the day and the results were amazing. They removed a huge amount of gunk from the pipes and the radiators are now hotter than ever. A great job and well worth the money.

Ms. Cruickshank (Huntingdon, Cambridge, August 2019) - System: 12 radiators on copper microbore pipes. Problem: One radiator not working at all, some are luke warm - Powder Flush came out within 2 days of booking, we had heat restored to all 12 radiators and have had to turn our thermostat down. We had a new pump fitted and both heating and hot water is exceptionally quiet now. We are exited to see the difference to our heating bills this winter. We are so pleased and really would highly recommend Powder Flush.

Ms. Goodwin (Colchester, February 2019) We are incredibly grateful for your amazing work. As the house is so old we are very used to people telling us that things are impossible to fix because of the age of the property and we were pretty convinced that we faced the huge expense and upheaval of renewing the whole heating system. It was miraculous that, in just one day, you managed to revive the heating to a level that has got it back to a level of operation we haven't had for ages and with so little mess. The house is warmer than it's been for years and at a fraction of the cost of renewing the system. I can't recommend your service highly enough, I have already given your details to one friend and will happily recommend you to anyone in need of your service.

John and Madeleine (Cambridgeshire, November 2018) We had three radiators that were permanently cold, the rest lukewarm and a boiler that banged and clattered like there were a team of goblins at work inside it. Stephen came out as arranged, arriving promptly, and worked solidly for about five hours. Though he had quite a lot of equipment he took care to minimise disruption. When he'd finished he informed us that he'd extracted about a kilo of sludge from the system. The result was astounding - all rads nice and hot and a nearly silent boiler. Nearly a month later everything is still working well. We wish we'd known about PowderFlush last winter. It's a quality service and we would recommend it to anyone with an old blocked-up heating system.

Ms. Hunt (Maidstone, November 2018) We had real issues with blocked pipe work, the heating system had ground to a halt. We had a new pump fitted and other things by another company but they left with no idea but rip it out. After research the Powder Flush seemed a good option to try. Stephen turned up spent a whole day working around our 11 radiators and all we can say is a massive thank you, we have a working heating system again and more heat than I can remember. Well worth every penny cannot not recommend this enough. 

Mr. Kaye (London, October 2018) We had tried a normal power flush that didn't work, when trying to fix our four radiators that were cold, but Powder Flush got them working in a day. Not cheap as I went for the no fix no fee solution at £1500, but the other solution of relaying new pipes, flooring, boiler and rads etc would have cost at least £5000,so it was a no brainer! We are now looking forward to a nice cold winter so we can hug our hot radiators!!! Well done POWDERFLUSH.

Mr. Milligan (Hove, August 2018) My heating system has a new lease on life with the removal of 2 kilos of sludge and inner pipe build up. The unique Powder Flush technique is brilliant! Stephen is the creator and patent holder for this amazing radiator cleaning system. He is very personable and so easy to work with. I am one very satisfied customer (after using Powder Flush on two different properties)!

Mr. Wyatt (Oxford, March 2018) I had a Powder Flush on my microbore central heating system (11 radiators). The system was 37 years old and had never been flushed. It was evident from the start that Stephen was professional. The flush proceeded smoothly throughout. He showed me the sludge that was removed. Thereafter the radiators heated more fully and evenly than they had previously. Soon after the flush a new boiler and magnetic filter were fitted, which required removal of a length of 28mm pipe. The bore of this was perfectly clean. Stephen also fitted a new TRV on one radiator. It was also necessary to fit two new pump isolating valves, for which Stephen had to go shopping. Nothing seemed too much trouble and his charge for this extra work was entirely reasonable. I recommend Powder Flush without hesitation. Your system will be in safe hands.

Mrs. Warren (Hemel Hampstead, January 2018) We had a situation where four of our eight radiators were working intermittently. A friend, who is a plumber, managed to get the radiators working but only four at a time and not always the same ones. He said he could take up floorboards to find the cause of our problem, but it was most likely gunge in the pipes built up over an indeterminate number of years. We talked about power flushing but he said a colleague had recommended a new innovation “POWDER FLUSHING" as it had a far superior success rate. We looked up the company together, filled in the details of our system. We were quickly contacted back with some available dates – all done on the internet simple and fast. The engineer arrived and quickly got to work discreetly and efficiently and worked for nearly eight hours reconciling our problem. He rid us of an estimated 20 years of waste changed over a filter and left us in a new world of heat. The whole system has been turned down as it is working so well. We would have no hesitation recommending not only the POWDER FLUSH system but the engineers, as trustworthy and hardworking. 

Ian (Reading, December 2017) For those of you who have found this website I was sceptical, as probably you are right now. Well here goes? We moved into our house 15 years ago and the central heating wasn’t very good. Had the system upgraded from gravity system to a fully pumped system by adding new pump, 3 port valve thermostat and timer controller. The system worked better but when we could afford it new radiators (7) and a new boiler was installed. These changed made vast improvements to heating in the house at the time of install (10 years ago). Pipework not replaced only altered. The 2 radiators in the lounge diner (last on the circuit, furthest from the boiler) have always been bad for warmth heat at best. If fact it’s the coldest room in the house especially the diner part which is good in the hot summer months but pretty bad in the colder months. I was recommended a power flush by a friend, who said it’s the way to go, which we had done and it did make a slight an improvement for a while. After carrying on like this for a few years we thought, just to bite the bullet and rip up all the fitted carpets, move the furniture into storage and have the whole house re-piped as it was the only way to be sure?! I did an online search and found POWDERFLUSH, read the testimonials which all were very positive. The process made total sense to me, but no one I spoke to had heard of it, some even warning against it. The engineer arrived bang time and commenced to the job in hand and by mid-afternoon our heating system was back online. Make sure you see the video on the process on this website. I waited 6 weeks before I submitted this review, just to make sure. There are many products and claims on the internet to improve heating etc. but this actually really works!!! The Missus is happy too, so win,win. NB. I didn’t receive a discount or have any association to POWDER FLUSH just another very satisfied customer.

Mrs. Andrews (London, September 2017) I have a large system (19 radiators) that has been playing up more and more over the past 2 years. I have had it power flushed twice and there was an improvement each time, but eventually everything stopped working and I was told to replace the whole system. After some online searching I found Powder Flush and took up there No Fix No Fee deal. It took just 1 day to get everything working like it should with no damage or mess. I would have to say I was more than impressed and would highly recommend. They are not cheap, but they did save me a LOT of money.

Mr.Harris (East Preston, BN16, January 2017) Thanks again for your sterling work on resolving our heating problem. 1st Class service ,prompt professional and courteous, highly recommended ,especially as like all testimonials before we had been quoted for a new boiler and re pipe, which was totally un-necessary, our system is working perfectly again following Powder Flushing.

Jeff & Jane (Portsmouth, November 2016) Our 8mm copper microbore system with 13 radiators and only a seven year old boiler started to fail in October-the boiler was tripping out and was very noisy and 3 or 4 radiators were not heating up properly.British Gas told us that it was a circulation problem & after fitting a new pump, which did stop the boiler tripping out, said we needed a power flush and new heat exchanger at a cost of £1450 but with no guarantee that it would work!!! After talking to three local Checkatrade plumbers, none of whom guaranteed they could solve the problems, we called in the boiler manufacturer (Glow Worm) - their engineer said the heat exchanger was ok but we needed a "magnetic flush" which they would quote for via a subcontractor. Subsequently, they phoned to say that because we had a microbore system, they were unable to quote!!! While trying to find out about "magnetic flush" online, l came across the powderflush website. After talking to Stephen I booked it in. He arrived, on time, three days later and worked non-stop until 5pm. The boiler is now almost silent, our hot water is much hotter and all of the radiators were so hot that we've turned down the boiler temperature and the room thermostat, at a cost of £780. I have no hesitation in recommending this company.

Glynn & Jenny (Warwickshire, October 2016) I am pleased to recommend Powder Flush - living in an old house with an old heating system (15mm one pipe system) which we have hand held to keep working for a number of years we were reaching the point where having exhausted other options it looked like a new system. As a last resort I contacted Powder Flush talked through the challenge with Stephen who didn't seem too phased - just over a week later the work was done - and we have to open the windows it's so efficient.

Paul (Guildford, October 2016) Thank you for coming to my home and solving the problem with my heating. I was recommended to Powder Flush by a power flush company who said he could not carry out work at my home as I had 10 mm microbore pipes. I was told a regular power flush could block the pipes and make the situation worse. The downstairs of my home was cold and the upstairs hot when the heating was on. The downstairs radiators were hot at the top and cold at the bottom. They arrived at 9am exactly on time as agreed, and didn't leave until you were happy that the job was 100% complete at around 6:30pm. They are very knowledgeable on heating systems and know solutions to the problems. It was a pleasure to have a real expert working in my house when so many other times I have suffered with tradesman just talking, but I am not convinced they know what they are talking about. Powder Flush really do know how to get a home hot again. Having to turn down the heating now!

Mark (York, October 2016) Over the last two years we had noticed an ever increasing number of our radiators stopped producing any heat, this came to a head as the chillier temperatures arrived over the last few weeks. Of the 16 radiators in our house only 4 were working (system is 10mm plastic microbore pipes) and of those only two properly. We asked a few plumbers all said that the usual power flushing was too risky as we have the thin diameter micro bore piping. Being a bit hands on I started to take the radiators off myself and flush them however after the fourth one I had made no difference at all. Reading various forums online and web browsing I came across the Powder Flush methodology, read the testimonials and thought we had nothing to lose by giving it a go. Responses to my email and questions were really quick and polite, within a week or so Stephen was at our house and spent a day and a half working on our central heating system. This technology developed by the company is really smart alongside a man who knows his stuff led too every single radiator back working to full strength. Stephen was a pleasure, considerate, determined and fastidious. We now have a fully working, well balanced central heating system. His work has saved me a fortune.

Alastair (York, July 2016) Our experience was positive from first contact. A quick initial response followed by a choice of early dates and the engineer arrived on time, despite the distance. He was polite, friendly, informative and helpful and cleared up well. The job was clearly difficult due to the external boiler and because the 10mm microbore plastic pipe was very encrusted with hard deposits, but despite this he persevered and removed 2-3kg of deposits from the 8 radiator system. Following this all the radiators heat up evenly and to full temperature, something that hasn’t happened for a few years. We would recommend Powderflush without reservation. 

Sam (Orpington, Kent, 23 March 2016) Having just read the testimonials again after having our old central heating system Powder Flushed, i can say that they are true. For us Powder Flush worked extremely well, i can’t recommend it highly enough! Before booking the call out I read the testimonials with a certain amount of scepticism; "If this process was so good then why is it only offered by a single small business with a less than corporate website and minimal branding ?" We decided to go with it on the basis that sounded like a sensible idea, was only £120 more than a standard powerflush quote which by their own admission had a less than 50% chance of working. Our system had never worked properly since the day we moved in 2 years ago, the radiators just didn't get hot, one never got above luke warm and the back boiler banged away like a vintage engine. Then in March it stopped working due to the boiler overheating 5 mins after first switch on. A highly recommended local plumber confirmed that it was blocked and there were two options ; Powerflush or Replace. He said powerflush is unlikely to work so given the systems age best to replace. He was quite genuine, in that they were the only two options open to them as a company and he was quite honest about the fact that power flushing was probably unlikely to work. Our dilemma was that we had already decided that we would replace the system in the next 2 years, but not yet - we weren't ready with other renovations and couldn't afford to at this time. We then did some web searching and came across this curious little website. After reading the details we decided its probably worth a go as a last ditch effort before being forced to have to replace the system in a rush and sooner than we could realistically afford. The engineer turned up on time, was polite, clean and tidy. After the first hour he had removed over 2kgs of sludge from the system, the final total was probably nearer to 5kgs ! Basically the system had had a cardiac arrest and was totally blocked just above the pump. The sludge had a consistency of thick semi dried toothpaste and its easy to see why a powerflush wouldn't have had any effect. The system is now fully working, all the radiators get hot and the banging has gone, the system is now pretty silent and as effective as it can be. Our house and hot water has never been so warm and we can now plan the other renovations without having to worry about needing to change the system any sooner. Can't thank Powder Flush enough for a terrific job, and that comes from someone with all the interpersonal skills of Victor Mildrew ! A thoroughly professional job!

Mr. Constantine (Kent, 21 March 2016) If you have plastic micro bore piping in your heating system and its blocked, call this company now! We have 14 rads in our house two of which stopped working in any function 5-6 years ago, and a further two that stopped working in the last month. Having been advised by many companies that power flushing is unlikely to fix the issues we had and that the only answers was to replace all the pipes at considerable expense, I researched micro bore cleaning and found this company. It took me a while to speak to a human and book a cleaning but I can hand on heart say it is definitely worth the effort. The gentleman that came was polite, courteous and arrived at the agreed time. Caution was taken to cover carpets with dust sheets to keep the house clean despite the grunge and sludge that was coming out of our heating system. After several hours of cleaning and even more cups of black coffee miracles started occurring. The two radiators that had not worked for 5-6 years were back up and running along with the other two that had ceased to work in the previous month. Our whole heating system is now up and running in full working order for the first time in years and myself and my family can't heap praise upon the company and gentleman enough. Yes it costs more than a power flush, but it actually works and costs a hell of a lot less than replacing all the pipe work that other companies would have had us do. All aspects of the work carried out were explained before and after the job was complete and thanks to powder flush we have a warm snug home again. Thank you.

Martin (Cambridge, 21st November 2015) We have lived in our home since new, nearly 20 years old, which has a micro bore central heating system. Without realising overtime the system had become less efficient & the heat output poor. The radiators at the extreme of the heating system were virtually ineffective taking an age to generate any heat. During the winter months it became difficult to utilise the conservatory due to the cold. Following the annual boiler check from British Gas we were advised that the best solution would be a power flush but in fairness told that there would be no guarantee of its success and that BG do not 'like' performing the process on micro bore systems. Next followed some research on the web and I found POWDER FLUSH. Found the video's good & the testimonials reassuring. Made contact, discussed the symptoms & booked the service for the Saturday. The engineers turned up at 9:00. Spent 7 hours cleansing the system, numerous cups of coffee consumed & the house returned to full heating! They removed 2 kg's of sludge from my 13 radiator system. What a difference, now running the boiler on a reduced setting, all radiator thermostats turned down & the main thermostat also down. Would I recommend POWDER FLUSH - Absolutely! Given the alternatives it is a no brainier. Hope this convinces you if you are unsure.

Mr. Youell (Hampshire, 20 November 2015). My system was taking up to 60 minutes to get hot. I knew that it needed cleaning and I considered flushing the system with chemicals and taking off 10 radiators and flushing them out. However, this doesn't get to the sludge in the pipes and I had microbore pipes. Looking at the time to do at least two flushes and draining down 10 radiators was not really an option for perhaps a 20% gain and not getting to main issue sludge in the pipes. I saw POWDER FLUSH online and this seemed to be what I required. I contacted POWDER FLUSH and we had a dialogue on my heating issues and symptoms. I agreed to go ahead on a “no fix no fee basis”. I had nothing to lose. Within 1 hour of starting the amount of sludge removed was staggering. Not only was the sludge removed, the whole system was inspected in a thorough and professional manner. We discovered a malfunctioning diverter valve and I had a Magnetic filter fitted for future protection. The system was completely flushed over a period of 5 hours. The radiators were balanced and at the end the result is.... the system now gets hot is around 15 minutes saving lots of gas. The boiler and pump are now silent. The engineer is extremely knowledgeable and explained the whole process in clear and simplistic terms. He made valuable suggestions that have since proved to be cost effective. He is completely reliable and arrived when we said he would and the quote was spot on. I fully recommend this process if you have microbore. There were no leaks and no issues post the process.

Mr. Hunt (Alcester, 12 November 2015). Before POWDER FLUSH visited, my system of 16 radiators was in an extremely poor state, although most of the radiators have been replaced since we moved in 14 years ago, the pipework and boiler has not been touched since the late 1970s and the number of radiators working has continually declined over the last few years until there were just 2 working properly. The pump failed last year and was replaced with a new one that struggled to barely push the water around the system at all. I was quoted over £1000 by British Gas to flush the system and even then they were not that hopeful that this would be effective as the majority of my pipes are 10mm microbore copper. After researching the effectiveness of power flushing online I came across POWDER FLUSH and immediately the concept made eminently more sense. Use an abrasive inside the pipes to scrape them clean rather than just water flow. I contacted POWDER FLUSH by email and phone and found them very helpful, responsive and we agreed a no-fix-no-fee price for my clean. This was done yesterday and to say I am amazed is an understatement!! POWDER FLUSH turned up at exactly the time agreed and ran-through the details to be carried out, then without any fuss just set up and started the process – The engineer definitely knows his plumbing, I have been trying to figure out my "Heath Robinson" system for years but he knew exactly what to do. I watched the whole process which is fascinating and to see what POWDER FLUSHING removes from the pipes, is incredible (including large lumps of excess solder and stones!!). The process is extremely thorough (no quick bodges here) and The engineer even replaced a TRV and unnecessary pipework fittings where it made improvements to do so. After a full-on 8 hours (He didn't even stop for lunch) They worked a miracle. I now have every single radiator working the way a new one should - some of which haven't worked to my knowledge for around 10 years, the pump is now running at 4 times the speed it was before and the boiler (which is almost 40 years old!) is so much quieter you wouldn't believe it. I certainly feel that POWDER FLUSH is the only way to go, they are professional, experienced, very reasonably priced considering the results and do a very high quality job. I don't usually give testimonials unless work is to an incredibly high standard so draw your own conclusions - I would recommend them without hesitation.

Mr. Watson (Bristol, 27 October 2015). Having suffered 2 years of warm or cold radiators and having "normal" gravity flushing carried out on a number of occasions to no effect, enough was enough. Discovered POWDER FLUSHING through the Power Flush Association website. As my central heating system was based on copper microbore, powder flushing appeared to be what was needed. Made contact through the quote page on website and reply received within minutes giving price and available dates. Agreed 27th October at 9am. At 9am on Tuesday the bell rang! As others have remarked he just got on the job, had 3 mugs of black coffee during the 6 hours he was here and presented a system at the end where all radiators were hot and no strange sounds coming from boiler. He also replaced my magnetic filter which had had its thread severely compromised by a previous installer and the central heating pump which was quite old (my suggestion). This was a professional job by someone who knew his trade. Would recommend without hesitation. Hot radiators again!! Thank you

Mrs. Gibbon (Scarborough, 20 October 2015). Well, to us this unique and patented approach to clean out the gunk from our central heating system with those narrow pipes (plastic micro bore) and 'creative' network hidden behind smoothly plastered walls, is just wonderful. Powder Flush shows up when they say they will, and don’t give up until every single radiator is free and working perfectly. They are also pleasant to have in the house, polite, friendly, works cleanly and totally efficient. This system is the ONLY one that works, whatever any other disgruntled or know it all plumber, DIYer or neighbour or friend says. Luke warm, cold, half cold half warm radiators fed by tiny pipes, well, it needs more than a power flush and god knows what cleaners in the system, magnetic filters and inhibitors - we've had them all, and I'd say, just let the man do his job, he knows what he's doing, has perfected his ideas and approach, let him do it, and look forward to warm and cosy winters. H&G.

Mr Philips (Sussex, 10 September 2015). I have been having problems with my system (plastic microbore pipes) for years, pumps breaking, boiler playing up, etc. I had the system power flushed each year for the past 2 years and still 2 radiators didn’t work. Finally, my plumber gave up trying and said I had to replace all the pipework, if I wanted to make it all work right. I didn’t want to spend thousands - and - have all the disruption to my rental investment. I tried the “no fix no fee” option with POWDER FLUSH. I felt that I couldn’t lose: If POWDER FLUSH fixes it all, I pay them a quarter of what a new pipes would have cost and save a month of disruption. If they don’t fix it, I pay them nothing and replace the pipes as recommended. They arrived, bang on time, had a look at the system and started work. When they started they explained that the system was at least 80% blocked. After four hours, I was told that everything has been unblocked and should work fine on completion. Two hours after that everything was back to normal AND everything was working correctly. Firstly: great technology, it’s amazing to see how much more POWDER FLUSH gets out of a system that has already been power flushed twice. Secondly: Thanks for giving me a no risk option AND fixing it all in just one day. It was a big worry that is now gone.

Mr Charlesworth (Surrey, 4 June 2015). We recently moved into a house with a 50 y.o single pipe system of ancient radiators which had never been cleaned out. The boiler was working overtime and breaking down, heating bills were sky high and many radiators either cold or too hot to touch. The upstairs loft tank was filled with sludge and the hot tank pump so noisy it kept us awake. So in fairness it was a genuine challenge to fix. The local reputable firm told us that a standard 'power flush' would be ineffective and quoted £2,500 to manually remove every radiator, hose them in the garden and reaffix with new larger bore pipes attached - a 3 day job. Even after this, they warned the system could not be fully cleaned and would likely clog up again so suggested replacing the whole system! I came across Powderflush online and the other testimonials sounded almost too good to be true. But I emailed Stephen who got straight back to me, confident they could do the job. He even offered a money back guarantee option. I remained a little cynical but had little to lose vs the alternative. Thank God I found him before wasting £1000s like so many others. He did the job in person and took all day. He was prompt, polite, professional, considerate, helpful, clean and kept me informed throughout. He's an expert in electrical systems, plumbing and boilers as well as the flushing process so he is ready to handle any eventuality. A huge amount of hideous, hard sludge was tidily evacuated. The system is now clean, efficient and most amazingly, it's quiet. He also gave me some great advice on TRVs and keeping the system running more efficiently. These guys work miracles. Don't look anywhere else. Whether you have real challenge or are simply looking at a standard power flush, Powderflush does a better job at better value and no one else can use the technology. If only more traders were like this.

Mr.Mahon (London, 15 May 2015) A national company, with whom we have a maintenance contract, came to carry out a “routine” annual service of our hot water and central heating system, and left us, three weeks and five visits later, with no heating in five of our nine radiators. Having carried out an ineffective powerflush, they said the only solution would be to replace our small-bore copper pipes with larger ones, a disruptive and expensive process. Close to despair, we found the Powderflush website and called to book, they came within two days, arrived on time, and carried out a powderflush. Within six hours, all the radiators were cleared. That was six weeks ago and the system has been working well since their visit. In fairness to the national company, I must report that the engineers who called were always prompt and polite, and that their accounts department has since refunded the fee for the ineffective powerflush.

Mr.T.Walker (Manchester, 1 February 2015) I had my central heating system (plastic microbore) powder flushed after 6 of the 12 radiators were not working. After a 10 hour working day Stephen got all the radiators working and the system seems a lot more efficient than before. My next door neighbour had the same problems as myself but went down the route of having all the pipes replaced which cost thousands. I am extremely happy with the service and would definitely recommend.

Mrs. Hussain-Shah (London, 6 Jan 2015) We moved into our new house in November, only to find that all but 1 of our 13 radiators were not heating up at all. We tried a power flush and after numerous engineer visits it was concluded that the entire central heating systems pipework would need replacing together with the boiler! Dreading the disruption of the carpets and flooring being ripped up I gave Powder Flush a call and they came promptly within a few days. After a quick inspection they explained all our central heating pipework was over 90% blocked, but they were optimistic they could restore the system. Stephen worked very hard and by the end of a long day he had managed to restore the heating to the entire house!! The results are amazing a warm house and a happy family. A bucket of black sludge was produced with large chunks of sediment that the power flush had neglected to shift. Stephen also took time to explain how to get the best from our boiler and heating system. I would highly encourage anyone to give a Powder Flush a go, if they are having heating problems. Stephen was also kind enough to return a couple of days later to do some valve adjustments to the radiators so that the heating was optimised in the house. After waiting almost 3 weeks to write this review I am happy to say that since Powder Flushes visit the heating is still working well.

Mr. Preston (Leicester, 12 November 2014) We have a plastic micro bore system that was running warm with one radiator that had been cold for months. The Powder Flush Company were the only one that gave me any confidence that they could cure my system, they came and worked very hard, did more than first agreed and kept my home clean all the time. I have had a magnetic filter fitted on Stephen’s recommendation, so now my system is running hot and reliable. Thank you for your excellent service.

Mr. MacKley (Herts, 2 November 2014 ) - I have a plastic micro bore system and have had various work done to the system to get it working properly over the past 3 years, including power flushes. One by one my radiators stopped working, even after all the plumbing work. I was told that there were no answers and I had to replace it all. I called this company as they specialise in micro bore piped systems and agreed a price. It only took them 8 hours, to get it all working and I saved having to rip it all out and not having heating for 2 weeks and some money. Very happy with this company!

Mr. Hill (Kent 28 September 2014) – We had a new boiler installed about 3 years ago and it has been nothing but trouble. Had several parts replaced, worked for a bit, then we had a problem with heating and hot water being only lukewarm. Had a professional power flushing company round, because our system is apparently complicated. It has a heat store with 2 pumps. Had the whole system power flushed and had the 2 pumps replaced. All was fine for 8 months, then the same problem occurred. Heating and hot water lukewarm. Called the power flush company back, they said “system is clean has to be a part”. Had another company round to service the boiler, they refused and quoted for a new boiler because they said “it can’t be fixed”. So, I got a quote from the POWDER FLUSH people on a “no fix no fee” bases. It was a good deal: if they fix it, I pay the agreed money and if they don’t, I pay them nothing at all. In just 20 minutes of flushing, there was large flakes coming out of the boiler’s heat exchanger and 4 hours later everything was working 100%, like it was new. I honestly could not believe that the boiler just needed a thorough cleaning and that no parts were at fault. Every other company I talked to said that the boiler could not be fixed and other power flush companies would not guarantee their results. I would highly recommend this company and their no fix no fee deal!

Mrs. Smith (Oxford 2 September 2014) – Just saying thanks for bringing my microbore system back to life. I was told that there was no other option but replacing the whole system for new, as it was “too old to work on”. The pump kept on being replaced, boiler cut out every day and water was running in the loft tank. Glad to say that I found an alternative to full replacement. Thank you!

Mr.Lucas (Dartford 8 July 2014) – I am a tenant in a flat that has been having problems for 2 years. We keep on calling the landlord, which in turn send an engineer. They get things running and then it shuts back down. Our record “run” was 3 month between breakdowns. Our landlord contracted the POWDER FLUSH guys to clean the system. System got cleaned and every part of it is working, usually at least 2 radiators didn’t work at any time. I saw the rubbish that was removed and am very hopeful. I have been reassured that our luck will last this time.

Mrs. Day (Worcester, 2 May 2014) – We have a microbore system and 3 radiators were not heating up at all. I had my husband take them off and was them out, but nothing changed. We also had the local plumber change the valves, but that didn’t work and he could fix it either. We thought that it was a good idea to get it done by the powder flush guys on a no fix no fee basis, as we only pay if they can get it working. They were here as agreed and worked for 8 hours. Thankfully they got the whole system up and running and all radiators heat up now, as they should. Would highly recommend.

Mr. Sundeep (Leeds, 9 April 2014) – We have been having problems with our boiler on and off over 3 years now. Have had parts replaced and drained down several times. We opted for a POWDER flush over a standard power flush because we wanted the best chances of getting the system cleaned properly. The team from POWDER flush arrived at our house on time. After answering many questions about the problems we were having. They inspected the system and took a water sample. They reassured me that they understood the problem and will take care of it. About 7 hours and 5 coffees later, with the system cleaned and the boiler re-constructed (they fixed some issues inside) everything was working much better. They did show me what they took out and I was shocked at the amount of sludge for a system that has been drained so often. Hot water was staying hot and the radiators were much hotter than before. The radiators were also the same temperature on the top and bottom. I must say I am pleased with the result and their hard work. Thanks.

Mr.A.Cope (Bromley, Kent, 14 March 2014) - I have a system that has 50% plastic pipes. Many people might not know this but they are exceptionally hard to power flush correctly. I had some of the radiators go cold on the system, they did it one by one, with more going luke warm or cold every month. I had the first standard power flush 3 years ago, with very little in the line of results (4 still cold). The second power flush was 2 years ago and seemed to have more effect with just 2 radiators still cold, just 4 days after the flush the other 2 went cold again, as before. My wife and I resigned ourselves to having to replace the complete system as we did not see an alternative. My wife found the “powder flush” company online and I felt the process made more sense to us. I gave them a call and they were surprisingly confident on what they could achieve for us, I felt that the chances of success were high, so I would try it before I replace the system. Which is £7500 and 30 days of the house being a mess. It took 1 engineer just 7 hours to get all 4 radiators working correctly and I have never had the system run so hot, I am very impressed with this company’s professionalism, guarantees and capabilities and would highly recommend them. I did wait 2 weeks before giving them a review, just in case, but everything is still working as it should.

Mr. I Cecil (Worthing, 12 January 2014) – I was told by my insurance company service engineer that I needed a power flush, before they will change my pump. Their quote was a little high and I did some research online and found the powder flush company. Their prices were less than the insurance quote and apparently cleans better than power flushing. I felt that was two reasons to try it. I don’t have anything bad to say: the work got carried out within 3 days of booking, they were on time, very efficient and a lot of sludge (rust) came out. My system is clean, I have a certificate and the insurance company changed the pump the next day, All working fine now.

Mr. Willy Braid (Southampton, 17 December 2013) – I was having problems with an old central heating system, open vented. We have changed the pump, valves and some of the radiators and we were still having problems with the boiler banging and the pump being noisy. Every so often the boiler needed to be reset to get it all going again. I was not sure if powder flush would be the right thing for us as it is more expensive than getting a power flush. I didn’t want to risk paying twice so I got a powder flush done first. It took just 5 hours to get everything cleaned, working and balanced. All my radiators work now, the pump is quiet and I don’t even notice the boiler working.

Mr. Dan Moore (Bath, 10 November 2013) – I have a house that is only 12 years old. All the radiators worked in the beginning, then slowly got less and less hot. It also took longer for the system to heat up, over the years and the boiler as starting to “play up”. From what I could find online, I knew that microbore pipes are not easy to clean and I have plastic microbore pipes, which apparently is the hardest. Out of all 21 radiators, 3 do not work at all. I booked a powder flush and hoped for the best. The work took 12 hours to complete and fixed the 3 radiators and the boiler issue. It is good to, now, have heating through the whole house and not having to worry about it anymore. Very happy with the service.

Mr. Beasant (Guildford, 6 November 2013) – I have bought a house 6 months ago and 3 of the 9 radiators have never worked. I called a local plumber who added a cleaner and told me to “run the central heating system HOT for 1 hour per day” 4 months later, no result. Tried another plumber who took one look and said “re-pipe the system”. I gave POWDER Flush a call and they agreed to a no fix no fee deal. It took 7 hours, but all my radiators work now. Very happy with the service and result.

Mrs.Lovell (York, 2 October 2013) – We have a plastic microbore system and one by one the radiators blocked up and stopped working completely. We were down to just 7 working out of the 18 we have. So we got a power flush done by a local plumber we knew, that only “unblocked” 2 radiators and they re-blocked within 12 months. After that, we were told by 3 consecutive plumbers, that we had to re-pipe the whole system and that that was the only option we had. We found the “POWDER FLUSH” guys online and gave them a call. We agreed a "no fix no fee” deal and they came from London to do the work. It took them 2 days, but they got all the radiators working and they removed 4 kilos of sludge from our system. After having a power flush done, just 12 month before, I wonder what effect it really had, if any. If you are being told to replace all your radiators or having to replace your whole system, give POWDER FLUSH a try. With the "no fix no fee" deal they do, you can’t lose.

Mr.Harris (Cheshire, 12 September 2013) – I have a copper microbore system and have been having problems with the downstairs radiators for years. I finally decided to get it sorted after my insurance company kept recommending a power flush, so I booked them in. After waiting for 2 weeks because they were “busy” the day finally came, at least the guy was on time for 8am. He walked in the door, looked at the radiator in the entrance and said “It's microbore pipes, we don’t touch these. I would recommend you change all the pipes for standard sized ones!” and walked back out. Not having much in the line of options, I did some research on the web and found POWDER FLUSH. The prices were online and they were “not scared” of the undersized pipes, because they work on them all the time. They came out, spent 5 hours working on the system and got it all working. I am so happy that I have hot radiators again and ecstatic that I didn’t need to change all the pipes. I saved a huge amount of money, hassle and disruption to my life. THANK YOU!!!

Mrs. Tanner (London, 23 July 2013) -“After being quoted £750 by (unnamed insurance company) to power flush my house, I wanted to make sure that it would be money well spend. Did some research on the net and came up with powder flush. I was a little nervous about the effects of this abrasive on my old system, but they did re-assure me that it has been used on many systems without any problems and that it is not as aggressive as it might sound. Apparently, hard sludge is the same consistency old tooth paste. They came, they powder flushed: no mess, no hassle, no damage and the boiler stays on without tripping. It all cost £530, very happy and warm. Would recommend you to friends, thanks!”

Mrs. Pennington (Reading, 3 June 2013) - "I have had my local plumber drain my system 3 times, that didn't fix the problem. Then he tried a chemical flush, which didn't work either! After all that hassle I wanted something that will work, first time and guaranteed. So I tried a powder flush. They pumped 1000's of tiny balls around the inside of my system; you could actually hear it knocking the old sludge off. The company showed me the magnets before and after the balls went in. Before, the magnets had a fine black sludge stuck to them. After, it had large pieces the same shape as the pipes - and lots of it. Horrible to think that I had to pay more for heating my house, even better was to know that it is now gone and the system is working much better than before."

Mr. Sidhu (Leicester, 18 February 2013) - "I was told to power flush my system, so I did. It cost lots of money AND it did not make the system work, but I still had to pay for the work. Rather than power flushing the system again (not that that makes sense) I decided to POWDER flush as it was recommended for my type of system (open vented, I'm told). After only 4 hours the system works like it should and I wish I knew in advance that a powder flush would work better than trying to power flush it. Prices: The prices are not that expensive in comparison, they are even cheaper than the large insurance companies charge for a standard power flush. I would not bother getting a power flush again, it does not always work? ”

Mr. Walker (Kent, 20 November 2012) - "I was told by the gas board that my microbore system has to be replaced because it is blocked up with sludge and power flushing would be a waste of money. The cost was tremendous and we could not do with the disruption, either. After reading the POWDER flush website, I took up the offer guaranteeing the results. I am very pleased to say that; I am as happy to pay for a system that works properly as I am happy to save the cost of replacement."
