    A very Satisfied Customer

    Posted 08 March

    New boiler installation of old system. All my contact with Charlie and Carol was professional, informative and timely. I am very pleased with my new boiler and the resulting heat and hot water. Charlie's team - Ethan, Tom and then Lewis and on last day Harrison were excellent - thorough, patient (with all my questions) and gave a lot of info and updates of what they were doing and why. I would thoroughly recommend Heat Tech Services Ltd.

    Great boiler replacement job from a trustworthy local company

    Posted 15 January

    Heat Tech provided me with a competitive quote to replace our failing old gas boiler. They were able to carry out the work quickly in 2 days including relocating and replacing the old pump and valves, carrying out a power flush and replacing the boiler and flue. The work was carried out very efficiently with no mess and the engineers on site were very professional and friendly. They were even able to leave us with working heating and hot water on the night in between the first and second day of the job as it was very cold weather. All in all really happy and would recommend Heat Tech.
