Gas Safe Registration: Upon completion, our engineers handle all administrative requirements, registering your new installation with Gas Safe and providing the necessary Building Control documentation.
Waste Management: We ensure the responsible disposal of your old boiler and components, leaving your home clean and tidy.

Always super responsive and reliable. We use them every year for our boiler services after they installed a replacement boiler for us a number of years ago.

Steve and his team fitted my new boiler 2 years ago which I have been incredibly pleased with. The job was done really well, efficiently with very little disruption. Steve is very responsive to emails and always seems able to be flexible to customer needs. He has subsequently serviced my boiler twice since installation and I continue to be extremely pleased with his work. I would recommend highly.

Steve and his team were great. Gave balanced and unpushy advice on the best boiler for our purposes, and then installed the new one really quickly and efficiently. He comes once a year to service it, always efficiently. Would recommend him to anyone.

Have been using Stephen for three years for the annual boiler service. This year's visit involved stropping the boiler down for a deep clean and replacing radiator valves. He is punctual and tidy and explains what he's found, what needs doing and what may need doing in the future. Have recommended him to fiends who have been satisfied with his work.

Thoroughly recommend Aqua Heat. All my dealings with Stephen have been nothing but professional, clear, considerate and honest. He fitted several radiators for me as well as servicing an ageing boiler in an entirely outdated heating system that will soon need need a complete over haul. Up front on cost, timeline and different options, and unlike other engineers I tried who just wanted to replace everything, Stephen really has helped sustain my current system whilst I plan for the future, all running beautifully.

Steve called me back after leaving a voicemail and arrived to my flat within 2 hours of the phone call. He was friendly and polite and located the problem within my boiler in no time and then fixed it accordingly. All in all it took 25 mins and my boiler was back up and running. I will definitely use him again.

Steve recently fitted us a new boiler very quickly and at a very competitive price. The work was done to an excellent standard and I would have no hesitation in recommending his services.

I contacted Steve on Wednesday evening, he was at my door next morning at 8.45 and did a great job repairing a leaking boiler and necessary repairs to cure the constant drop in pressure and need to fill the system regularly. He also performed the annual service. He even came back on Saturday morning to check it was all ok as there was still a very slight drip from the air pressure vent. The boiler is now purring sweetly. Steve is very a knowledgeable and accredited professional. I have no hesitation recommending Steve and he is reasonably priced compared to others I have used in the past who have not done such a good job.

Stephen installed a new boiler and provided an excellent service. I got quotes from a few companies and his was the most transparent on both what the work involved and cost. He turned up on time, did a fast but thorough job and left everything in a clean and orderly fashion. I've since used Aquaheat to service the boiler and will be using them again. Great service!
