What a service
What a service? Excellent, amazing and of high quality. Barry Nichols is a hugely knowledgeable plumbing engineer who possesses a vast amount of knowledge. The best ever tradesman I have had the honour of interacting with. Barry's information, advice and guidance about the power flush process plus extras was by far second to none. Barry is a very personable and likeable chap. I am very glad to state that I am a very satisfied customer, one of over 4000 Barry looks after diligently.
Fast response, efficient and successful service.
They helped by fitting in a fast and urgent powerflush for me to fit in with the time the boiler fitters had available. That meant my broken down boiler could be replaced only 2 days before the really cold weather of heavy frost and snow shortly before Christmas. As an older person living alone it was was a great relief to be able to fit this in. Milto, the man who did the work was efficient, pleasant, and informative and reduced my stress.
Excellent Service
Barry was an absolute star. Carried out the powerflush quickly and efficiently. Gave lots of useful advice and identified faults with the boiler that had been missed by the boiler service engineer.
Bad experience
My central heating system started failing pretty much immediately after the engineer (Barry) completed the powerflush, took payment and left. I rang him directly but he wouldn't return to help me fix the problem, saying that he knew less about my boiler than I did. He later rang briefly with some advice that got the boiler back to life temporarily before failing again. I got no response to calls to the engineer the next day and so requested compensation in lieu of help. This resulted in a 'see you in court' phone message and later an assertion that it was 'my boiler, my responsibility'. I really would have hoped for a better response given the poor 'customer outcome'.
In terms of the advice I received during the day, although some of Barry's advice made sense and was useful, other advice seemed questionable to me and in conflict with the current trend towards reducing CH output temperatures in order to optimise the efficiency of condensing boilers like mine (see for example theheatinghub.co.uk/). At a certain point in discussions Barry would add weight to his arguments by referring to his fifty plus years in the business, which is fair enough but made me wonder whether perhaps Barry had been left behind by current thinking.

The name says it all
Excellent professional service...replied quickly to my email, booked me in short notice. I am ecstatic after experiencing problems for over a year, had a serious blockage the radiators at the front of my property were not working at all and now my home is finally toasty (I was grinning like a cheshire cat all evening)
Barry was sat outside before 08:00, he explained the procedure, it was apparent from the way Barry worked that the previous powerflush carried out a few years ago wasn't done correctly, I was shown the crud being flushed from my system.
Barry was also respectful of my property he bought along his slippers for when he was inside, showed due diligence throughout the day he also has a good sense of humour.
I cannot recommend this company enough...many many thanks Barry.
Does what it says on the tin!
Looking at all the reviews regarding Barry's ability & Powerflush know it all.
"Ditto"
What Barry didn't know about this business isn't worth knowing, if your looking at getting a powerflush just fill in the online quote & let him do what he does, say thank you & pay him.
JOB DONE. Well done & thank you for all you done & your advice Barry.
Excellent service
Barry was on time, extremely knowledgeable & very informative - I was clueless on what was needed but he resolved my heating system issues and I was very satisfied 😊👍
Barry was the ultimate professional
Barry was the ultimate knowledgeable professional and managed to resurrect most of our system. We were left with a couple of radiators that we had a feeling were not going to be fixed by the flush anyway. Arrived on time and provided lots of valuable information throughout the day and he was non stop all day trying his best. Thank you Barry much appreciated.
Highly Recommended!! Excellent Job done
Barry arrived 8am prompt as agreed. He was so professional, friendly with a great sense of humour. He started work straight away without any waste of time. He Powerflushed my radiator system within 6 hours. He tidied up and left every where spotlessly clean.
The job was excellently done beyond my expectation, in a very competitive price. I wouldn’t go anywhere else.
My hot water and radiators all working perfectly well.
I highly recommend Barry (Powerflush Know-it-all).
Powerflush - Amazing!
Powerflush were so professional, knowledgable, honest and friendly too. I know that should be expected, but it isn't always the case
Powerflush inspected my heating system and advised that I didn't need a Power Flush. You really don't get that level of honesty every day!
Even more amazing, Powerflush didnt want to charge me for coming out, inspecting my heating system, fixing something very small and giving me great advice (heating hints and tips)...again rare and so kind
Thank you so much Powerflush, I would definitely recommend you to anyone
Terrific service, don't bother to call anyone else
If you need to flush your central heating system and you live in Kent - there's only one company to contact, Powerflush Know-It-All just call 0800 3892767. I contacted Barry Nichols, the Powerflush engineer after getting a quote for over £900. Barry explained the process over the phone and gave me a quote for less than half that sum. It took him less than a day to do everything, he is knowledgeable, skilful and friendly. He also didn't leave any mess.
Very helpfull and knowledgeable
Very helpfull and knowledgeable, customer satisfaction is number one.
Very well prepared and presented.
No short cuts taken an does what it says on the tin
Will use again and refer to friends and family.
Thank you Barry
We had a problem with our boiler
We had a problem with our boiler , was told we had a blockage and needed to have it powerflushed, was recommended this company. Great choice from the booking which was easy the quick response. He turned up on time worked hard explained every thing well he fixed that problem and picked up another one we had . He was polite and knowligable we are very happy with the service.
Very happy with the work that was done…
Very happy with the work that was done very professionally.Hopefully no more problems with my heating .
I totally agree with all the other…
I totally agree with all the other comments on the other reviews.
Barry arrived promptly at 8 and did the job efficiently and professionally.
He told us tips for efficiency.
For the first time in a long while the heating is working brilliantly. The boiler is quieter and healthier sounding.
The extra add on radiator had never worked very well but is now blazing hot.
Thoroughly recommend him.
Reasonable rates too.
Power flushing our central heating system
Our central heating system is quite old and the water was very dirty from corrosion in the system. The Engineer phoned two days before coming to flush the system to check if it was still convenient for him to proceed. He arrived when agreed, and was efficient and professional. Despite our system being quite rambling, he made an excellent job of flushing every radiator, towel rail and the hot tank. He also passed on some very handy information on how to help prevent the system becoming dirty again.
I am very pleased with the result, and think it was good value for money.
I emailed Powerflushknowitall for a Quote
I emailed Powerflushknowitall for a quote on powerflush of 9 radiators & was quoted £540, i decided it was too expensive so i started to contact other powerflush companies, all the dates where over 2 weeks so I decided to contact powerflushknowitall again by phone i gave barry all my details explained the issues/number of radiators, I was quoted £460. Next day I get a call from Barry saying because I asked for a quote though email it has to be £540 & that he had mistaken my address for Coventry that's why he quoted £460. (I don't know if he's lying or being truthful, ill let others decide?) all I can say is its best to contact this company by phone you will get a far cheaper quote than by email, Now! from his reviews here I do believe he would have done a great job, its just unfortunate this happened, when I first phoned him I did tell him I emailed his company but he couldn't hear me as he was in traffic, Barry also said he would do the powerflush for £500 but he wouldn't make anything, making me feel guilty so I accepted £540 quote, after listen to family & friends I decide to cancel the appointment with this company & find someone local.
Edited
Barry you know exactly who I am, I sent you a message saying word for word on 06/04/2022 at 14:48
Thanks for everything but family decided to get powerflush locally.Pls cancel appointment for Bxxxxx on 21st April.
I guess what happened to me must happen a lot? you contacting the customer saying the price quote was incorrect because I thought you said a far away location. guess I got my answer if you was lying or not.

Knowledgeable and Reliable 10/10!
Barry did a fantastic job on our heating system - arrived promptly at 8am and worked solidly. He really knows his stuff, and shared lots of helpful information with us whilst he was there. Wish there were more tradesmen like him around!
Barry knows it all
Barry is an honest and flexible guy. I paid him for a house in Chatham who told me it was not needed after he visited and tested. He visited another property in Crayford and confirmed the power flush was required in that property. He also helped with some left over electric work by the boiler installer. He knows it all and is a good man who has worked in the plumbing / power flush trade long time. I will use him again and he is highly recommended!
