EXCELLENT Based on 67 reviews Lindsay SmithSeptember 29, 2025Trustindex verifies that the original source of the review is Google. Great and efficient service - Ryan installed smart thermostats throughout the house, fitted new valves to 2 radiators (and replaced an old manual thermostat which didn't look great for no extra charge which he did without me even asking). I wouldn't hesitate to recommend. lynn moirSeptember 22, 2025Trustindex verifies that the original source of the review is Google. Had problem with my smart heating system - Ryan arrived same day within just an hour and got me back up and running. Would use again for other gas heating issues in the future. Graham SmithAugust 26, 2025Trustindex verifies that the original source of the review is Google. Very good service. Cane exactly when he said he would and fixed my boiler. AlbertLai2020August 19, 2025Trustindex verifies that the original source of the review is Google. Ryan is so fast to check my boiler next day. He is the first engineer I met so far to fully explain what the problem of the boiler is. Therefore I can estimate what is the ceiling price for repairing the boiler. After he has fitted the PCB to the boiler on the second visit, the boiler works again and no further repair is required. My tenant is very happy. I will definitely call Ryan again for any boiler issues in future. Thank you so much for Ryan! Ajit NaranJuly 25, 2025Trustindex verifies that the original source of the review is Google. Efficient both with the job and time highly recommend Mark HannaJuly 14, 2025Trustindex verifies that the original source of the review is Google. We purchased our new home and asked Ryan to come and service our boiler. Communication was fast and easy with details confirmed via email and reminder text messages too. Works were done quickly and professionally. Ryan talked me through what he was doing and left the areas as found. We then asked him back for additional pluming work which was also done to a high standard. Invoice came via email and payment was easily done too. Great to support a local firm and to find someone who provides a top level of service; rare these days! Charlie HibbertJune 7, 2025Trustindex verifies that the original source of the review is Google. Thermatek installed our new hot tap & service our house heating and hot water system annually, with an accompanying logical explanation of how the our system actually works, something other engineers weren’t able to do. Would highly recommend. Sarah PandeyJune 3, 2025Trustindex verifies that the original source of the review is Google. Thermatek installed a new boiler with Tado thermostat and removed our old hot water tank, as well as replacing a bathroom tap. The team were extremely professional, polite and kind and did a great job. We were very pleased with the work. We had originally got 3 quotes from different companies and Thermatek were the most reasonable of the 3. We would definitely recommend them. Thank you! Margaret E ThomsonMay 15, 2025Trustindex verifies that the original source of the review is Google. Ryan, from Thermatek, has been our go-to plumber for many years and is happy to come out for all sorts of plumbing related problems, big or small. He is able to access replacement parts quickly, for example, flush valves when they fail. He is totally reliable and arrives on schedule, works quickly and tidily, leaving everything sorted to my entire satisfaction. What better recommendation! KiwiMay 14, 2025Trustindex verifies that the original source of the review is Google. I recently had my traditional heating system and accessories replaced with a combi boiler and am very satisfied with the results. From the initial inspection to installation, Ryan was professional and responsive. He explained the options and their pros and cons as well as recommended efficient choices based on my home's needs. The installation was quick and neat, also my home was left clean and tidy. I appreciate Ryan's expertise and commitment and I highly recommend him for gas heating services.
