Powerflushknowitall Reviews 

Barry is brilliant, clean, efficient and very knowledgeable about his subject. Our central heating and hot water pipes where blocked solid but are absolutely perfect now. He not only cleans the pipes but also cleaned every radiator separately. Can't recommend him enough. Thank you Barry

On one of the hottest days this year Barry worked hard to power flush our heating system where water was flowing into the header tank whenever the gas boiler was in operation. He gave excellent advice and detailed explanation of what was happening. He is such a tidy and well ordered worker who went out of his way to accommodate our living arrangements. Everything was completed within the day to our previously agreed price.

Barry was an absolute superstar. He was attentive, knowledgeable, and extremely helpful. He clearly knows his trade and did a very efficient job throughout.

He went above and beyond when replacing all TRV valves, one of the radiators had a broken wall bracket and he fixed it without extra charge.

Unfortunately, this didn't end up fixing my boiler problem, but I don't hold that against him — he did a great job and I really appreciated his professionalism and care.

Would definitely recommend Barry and Power Flush Know It All.

I gave this rating due to the following reasons- 1. Prompt and quick service, called them yesterday for a quote and got it done today. 2. Very knowledgeable that we had a mini briefing on the use and maintenance of the boiler and the controls.3.Price seems reasonable.
The radiators were all working very well soon enough and we are happy with the outcome.Thank you.

Can't praise this company enough. Excellent service;friendly knowledgeable engineer who has learned through experience and explains everything.
Our system was full of sludge and performed poorly. Barry gave advice on system use and even fixed a broken valve on a radiator which burst during the flush. All radiators work well now; no cold spots.
There is another company with a similar name that comes up in a search. I don't know anything about them but Powerflush Know It All do a top job at a fair price (unlike BG). Highly recommended.

Even though Barry did a good clean job with the power flush and he is very knowlageble in his professinal work.
He even put on house slippers while working in our home.
But his conversation and comments to my wife, who was at home allone as I was at work where very inapropiate, he talked about his sex life and even asked my wife about our sex life.
If you use this company it would be advisable to have a man at hone while he does the work.

Booked to do work ASP and arrived on time . Completed the work very efficiently and then checked the heating system was working properly. Barry the engineer was very experianced sorting out minor system problems without fuss. He was also able to point out the work my Homecare engineers should be doing on next visit. Parts of the system of our 26 radiators were not origanlly working and he was able to turn valves to ON , these were left not working during the yearly services. Very happy with the work. Recomend Powerflush know-it-all without hesitation.

I learned more about how central heating systems work in the first couple of hours of Barry’s visit than I had in my 52 previous years. Courteous, expert, reasonably priced and, most importantly, brilliantly effective. Radiators are all piping hot, water pressure is back to life, inhibitor is doing its thing, and boiler is happy.

Problem solved in a day.Everthing was explained as he went along.Looking forward to living in our nice warm house.Thanks.

Barry came and done exactly was was needed with the price given via email all 27 radiators all working
Extremely experienced and informative loads of advice given and over the moon with the price given
Came out within 2 days baring in mind its in between xmas and new year
Thank you so much

Barry solved an issue we were having with our heating that other engineers missed. He really knows his stuff. He even took the time to message after to see how we were getting on. Great service and very reasonable pricing. Highly recommend.

Excellent service at a fair price.
Barry the engineer was very experienced and knew exactly what he was doing, gave good advice, and also that he had tutored PowerFlushing during his many years as a heating engineer.
I would recommend PowerFlush, Know it all to anyone who has poor radiator heat.

Needed my heating system flushed because of issues with water continually filling the header tank, Contact tacted this amazing company requested a quote on line got a call from Baz and a visit was oplannned in a couple of days , Arrive for 8 am and worked continually on all my rads until thhey was running with clear water , used a heat gun to show me the cold spots . Heating is now working really efficient. I would highly recommend this Comapny. I didnt menation teh amout of information that Baz relayed about the system and how to ensure all rads were effectively working, also advising how and when to add inhibitor I would definately use this Company again.

Communication excellent throughout. Arrived when said he would, can’t recommend Barry and team enough. His skillset and knowledge is formidable as is his workmanship. Explaining in great detail as he goes along. If you have someone out they do a Powerflush in a few hours then clearly taken short cut. Barry cleaned and flushed each zone for underfloor heating and each rad in the loop thoroughly and individually.

Our radiators were not heating up. I contacted Barry of Powerflush, who visited us just a couple of days later, flushed our system and installed a new pump (the old one was 17 old). After this, the radiators heated up quickly and maintained temperature. Barry strikes me as a someone who really cares that his customers are satisfied and goes to any length to ensure they are, and he’s a truly nice chap too.

I could not be more impressed with this company. The owner, with 50 years’ experience arrived, himself. He arrived on the dot at 8am and worked all day until 6pm. As a result, we have radiators warmer than they’ve ever been. The price quoted was extremely reasonable and I am going to recommend him on our street WhatsApp. Thank you, Barry.

The team stayed on well beyond time to make sure everything was working.

Barry from Powerflush today carried out a powerflush to our radiators through out our bungalow. We would commend him for his workmanship through out this procedure. He has an exceptional knowledge of heating installations, he is also very polite and helpful and we were very pleased with all that he did and would not hesitate to recommend him to other people.

I had my radiators flushed in summer of 2024. They were working perfectly fine and in December I had two radiators not working. Barry immediately responded to my request and came within couple of days and fixed the problem. I really appreciated his quickness in resolving my problem as most companies once the job is completed and paid for don’t come back to the client.

Having used PowerFlushKnowItAll successfully in November 2024 and remembering what Barry said about helping customers, I contacted him last weekend with a question and a request for his help on an issue I was experiencing with my Megaflow water pressure and radiator bleeding. He rang back the next day (on the Sunday) to help and we spoke again today for 15 minutes. The help he gave over the phone meant I could resolve the issues and now, quite some hours later, having checked it several times since, my heating system is running sweetly again. Barry freely gave his help and as before, it was a pleasure dealing with PowerFlushKnowItAll.
