Powerflushknowitall Reviews 

Very satisfied, house is so much warmer after the job was finished. Barry, did a great job and was very amiable and pleasant the whole time even when the odd problem popped up.
I would happily recommend this company to any friends and neighbours

So many things about this company and Barry who carried out the work that deserve five stars. You would fall asleep reading! No fuss, no drama. Low disruption. Ultimately warm home happy boiler.! Happy me!
Will use again

It was easy to get an online quote which made it easy to go ahead with the work : Not the cheapest but not the most expensive either: £580 for 17 radiators in our house seems a reasonable price to me : The work took around 7 hours and was handled professionally and as far as I can tell competently. The radiators do feel hotter and I guess that is the key, providing they stay hot of course . The work undertaken was surprisingly non disruptive as most of the kit was outside and the only pipes were from our tank upstairs out through the bathroom window . Good solid and friendly service. I Would recommend .

We would recommend this company to everyone for its expertise and excellent service. The engineer not only understood our problem but also pursued it to the end, and gave us excellent advice on how to best run our ch system.

When you are looking for a professional, friendly, knowledgeable competent service; as well as excellent value - then Barry (who is a legend) and the team at Powerflushknowitall.co.uk have no equal.
Tradespeople with integrity, each job thoughtfully approached is what spreads the word of mouth as to why you should use this company.
They do what they say, use them!

Our boiler stopped working, and we discovered that before the insurers would fix it, we needed to have our radiators flushed! Having not known previously that this was even something that needs doing, I set about contacting companies who do this sort of job - little did I know that there was quite a demand for this service! Barry was the fourth one I contacted and was available to come sooner than the others I had tried. He arrived promptly on the morning of the job, was friendly and professional, quite a character! He explained what he was doing each step of the way, and showed how easy it is for some people to rip you off, making you think the radiators are clean, where that was only part of the job, and there was so much more to it. My husband, children and I were fascinated by the process as well! He even gave us a spare old pump for our boiler so we can have hot water in the meantime, which is so helpful as we are still waiting for the insurers to approve the boiler and radiator repairs! Would definitely recommend Powerflush Know-It-All anytime 💫

Following a quote from other plumbers, who advised we needed just about everything replacing, we contacted Powerflush for a second opinion (and quote). As this quote was a third of the cost of the other, we decided to proceed with them.
Barry arrived promptly at 8 a.m. on the appointed day, flushed the system and advised on other works needing to be carried out to the boiler and also advised us how to proceed with getting these works done.
Barry is incredibly knowledgable and seems completely trustworthy. I just wish we could get him to do all of our plumbing jobs as I know we would get a) a good price and b) a good standard of work.
I wouldn’t hesitate to recommend this company should you be looking for a powerflush job.

A very thorough job all done with great care. Thank you also for the very helpful advice about central heating systems.

We have just had all of our radiators power flushed - the work was carried out to an excellent standard. The engineer was very friendly, as well as knowledgeable, and explained what he was doing at every point. We would highly recommend this company!!

Excellent service, brilliant advice given and would defiantly recommend to others!

Thanks again

Barry arrived exactly when he said he would -to the minute. He was friendly, polite and really knowledgeable. He has 40 years' experience and is a qualified heating engineer and so he has a great deal of expertise. Whilst he was with us, he found that three of our radiator valves were faulty. It made sense- we had always struggled to heat one of the rooms. He repaired these for no extra cost. We sought three quotes and his was cheaper by £50 and £100.

Love this guy salt of the Earth. These are the type of guys I get to do jobs. Pride in what they do.

Great, honest advice on system issues and the 8 hours of flushing to sort my pipes out, I highly recommend this company.

Barry arrived at our property at the exact time arranged. He was professional and friendly, explaining everything that he was doing/going to do. He was respectful and kept everything clean while he did the job. He made sure we were happy with all the work before he left.
I would highly recommend this company. Thank you Barry !!

An excellent service from a friendly professional crew, also assisted by sharing knowledge to further help with any future problems. I would thoroughly recommend their service.

Great service, friendly and informative with good advice for improvements, didn't waste any time getting on with the job. Would definitely recommend.

Barry has done a fantastic job. We have had nothing but problems with our heating system for months, but I'm now sat in a very warm home with running hot water!

Barry was thorough, making sure every radiator was flushed. He explained the process and offered advice to make the most of the system (and make savings on our heating bill).

Things to note - it takes a while to do. For a proper power flush, it isn't going to be done in a couple of hours. As I hadn't a clue of the way it was done, I was surprised by how long it took and how thoroughly Barry did the work.

Also, be aware that you will have an increase in your water bill. It might seem obvious, but just be aware that water has to be used to flush the system and then refill it.

Thank you Powerflush Know-It-All.

Phoned on the Saturday and was able to get an appointment for Tuesday. Engineer turned up on time and worked hard for several hours clearing our system. There were two radiators that needed replacement thermostatic valves which he showed to me, but all the rest were piping hot before he left. Was very respectful of space and property. Would happily recommend.

Brilliant!!!! Absolutely fantastic service and experience. I rang powerflushknowitall for a quote, after previously had 3 other quotes from similar companies. The guy on the phone (I believe his name was Barry) was very helpful and answered all of my questions I had. The quote was similar to the others I had, within a few pounds but I decided to go with these guys as they seemed to know the trade inside out and that gave me a lot of confidence in them.
The engineer turned up 15 minutes ahead of time but considerately did not knock my door until dead on 8am. The first thing he did when he came in was take off his shoes and change into his slippers, which I found so respectful. He put dust sheets down everywhere and was here the whole day, meticulously ensuring everything was perfect. He was polite, cheerful and very knowledgeable. He even tolerated my 4 year old Son standing over him asking him which paw patrol character was his favourite!! Lol He cleared up after himself and my house was as clean as it was before he came (minus all the toys my son had dragged out to show him!!) He asked me to check the radiators before he left and they were super hot, I didn’t realise radiators could actually produce so much heat!! Before he had flushed them, they were like warm at best and had lots of cold spots. I was given the invoice and told to pay if I was happy with the work and I wasn’t pressured at all. I paid by bacs transfer and am very, very happy with my powerflush.
I read the negative reviews on here but I can not think of one negative thing to say. My experience with this company was brilliant and my house is now so warm I’m turning the thermostat down constantly whereas I was always turning it up before I had this done! I am really impressed and powerflushknowitall is a company I wouldn’t hesitate to recommend. If you’re thinking of having a powerflush done, please call powerflushknowitall, you won’t regret it.

First and only company I spoke to about my system needing a power flush.
Extremely knowledgeable, trustworthy and helpful.
Arrived on time and a thorougher job was completed.
Lots of advice on how to self maintain my system and tips given on how I could lower my energy bills.
Barry - Thankyou for a top service.. highly recommend. 10/10
