EXCELLENT Based on 57 reviews Clare ReillyApril 4, 2025Trustindex verifies that the original source of the review is Google. Really helpful! Phoned at 7pm and they spoke through the issue, booked us in and they came by 3pm the next day as promised and fixed the issue, plus an additional issue, really quickly. Great service, would highly recommend! Tim RooneyMarch 17, 2025Trustindex verifies that the original source of the review is Google. Couldn’t recommend Thermatek enough. Allayed all our doubts about converting from gas to heat pump, quick/clean installation and very reasonably priced. Kate Cargill AdamMarch 10, 2025Trustindex verifies that the original source of the review is Google. Ryan at Thermatek is trustworthy, knowledgable and skilled. We have only had positive experiences with him. He has recently come back to do our yearly boiler service which he completed thoroughly and booked us in automatically so I didn’t have to remember to contact him. When we lost our heating, he did FaceTime with us to help us get it working again in no time. Highly recommend! Paul LoveFebruary 27, 2025Trustindex verifies that the original source of the review is Google. Thermatek installed a Tado system for me, and they did a great job. The whole process was quick, well-organized, and really professional. No hassle, just got it done efficiently while answering all my questions. I’d definitely recommend them!

Brilliant fountains blogFebruary 10, 2025Trustindex verifies that the original source of the review is Google. Thermatek installed a Greenstar 4000 boiler at our house in January and we would highly recommend them for service, great value for money, professionalism and dedication. The team came, carried out a messy and complicated job with minimum fuss and cleaned up and replaced everything as if they had never been there. All within one day. Boiler works well and Ryan was very good at explaining everything so if you are wondering which company to choose for boiler repairs/installation, look no further.

I have now used him twice in less than a fortnight I wouldn’t think twice about using him. He arrived promptly when he said he would and did a great job thank you Michael ShawJanuary 17, 2025Trustindex verifies that the original source of the review is Google.
