Firstly, huge apologies for such a late review. Charlie and the team did our bathroom months ago.
It was professional from the get go. Charlie was superb at advising and keeping costs realistic. He explained things through that would make the bathroom less prone to issues.
Gary and Matthew ripped the old bathroom out quickly and made the space good then installed everything really efficiently. Then the tilers came and did a fantastic job.
Gary came back once done to move a couple of bits and was exceptionally professional and skilled.
Finally, we had a leak issue which was a quick simple fix and was done about a week or so later.
Months in now, so happy with the bathroom.
I’d totally recommend Heat Tech because from start to finish, it was a pleasure and the work is to a very high standard.

Great communication from the initial enquiry. Harrison arrived on site promptly, he was really polite and professional, and we were really pleased with the work carried out. I will definitely be using Heat Tech again in the future! Many thanks.

Charlie and Heat Tech are AMAZING!!!! I have had them do all my Boiler, plumbing and Heating installation for the last 17 years. I worked with many – but they are definitely the best by far! Always, prompt and friendly, he and his team of plumbing/heating experts are second to none. I highly recommend Charlie. 10/10

Very good experience with this company. The office was efficient and helpful. The visits were arranged with a minimum of delay.
The work was undertaken by a plumber called Levi who was very diligent and logical solved the problems in our underfloor heating system. He provided comprehensive advice on how to manage our now repaired heating system.

Job well done. My parents found Harrison to be most polite, efficient & tidy when replacing a kitchen trap. Would thoroughly recommend Heat Tech.

I had a major leak from my boiler during heavy rain fall. Charlie talked me through what I needed to do, out of business hours. What a gem. I ended up requiring a new boiler. All priced up, and Paul and James fitted it a few days later. Neat and tidy. I wouldn’t hesitate to recommend them, in fact, I already have. They are fair and reliable. Thanks lads.

Our boiler was broken last week. We urgently needed a new boiler instalment as we have a toddler in house and are soon expecting a new baby. Heat Tech has booked new boiler instalment in a short-notice. They came and did pretty clean and good work. I worked with Heat Tech for a couple of other repairs in house before. They are always reliable, friendly and providing quality service. A safe pair of hands and highly recommended.

Highly recommended – needed a tap replaced due to a leak, booked in for next day, arrived promptly, did a fantastic clean job and really good communications – thanks a lot!

Heat Tech have been servicing my boiler since 2020. I called them in to change my megaflow type system to a combi boiler. The manager Charlie talked me through my options and gave me his recommendations and explained exactly what would happen. His colleagues Alan and Harrison were great and were experts in boiler fittings and pipework. If pipework were an art, they would be Michelangelo and Da Vinci. Such skilled and competent workers, truly committed and taking pride in their work. Their work was neat and careful, not rushed or slap dash. They also fitted my new radiator and new shower. Lovely Mark came to take away the old boiler, tank and all of the rubbish the next day.
