Edit: 25/8/2026 Purely because I can't seem to add a second Google Review, I'm editing my first one. We had a heat pump installed in our house at the end of July, and the Gas Tech team was brilliant. Tom came to do a survey to start with, to make sure that the system he installed would be the right fit for our house, and for the week a bit for the installation, he and the team worked tirelessly to get everything done. The system works brilliantly for the hot water (haven't needed the heating yet!), and they've been very prompt with any questions that we've had. Previous review: Once again, the team at Gas Tech Heating team has come through! Tom came this morning with a new sensor for the boiler, installed it, and make sure everything was all in good working order. It is so nice to know that they are kind and reliable should anything go wrong with the heating and plumbing in my house.

Having dealt with 3 different plumbers/heating engineers and 2 new combi boilers in 3 years and still had no water pressure, I was at the end of my tether. Other companies just wanted money upfront for everything with no results. I asked round my neighbours for companies they’d personally dealt with and Gas Tech Heating was recommended by several people. Tom came round and quickly identified the problem (without any demands for payment in advance) and arranged to carry out the remedial work. This was done professionally by Toms father who arrived promptly and kept me informed what he was planning to do. I wish I’d found this company sooner. Fiona Macdonald.

New boiler systems will be covered by a warranty. We’ll talk you through the details, which will depend on your chosen manufacturer. Warranties usually require your boiler to be serviced – talk to us about future boiler servicing to prevent issues arising.
