10 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.Verified reviewerJob location: WD310 No hot water.

Had a boiler problem. Quick response to try and resolve the problem, though despite extensive efforts by Heat Tech staff, I needed a new boiler. From receiving a quote for a new boiler on a Thursday, the new boiler was installed on the following Monday. Fast efficient friendly professional local service, who I have used since 2006 and will continue to use.Verified reviewerJob location: WD3Response from Heat Tech Services Limited
Thank you for your review. Unfortunate as it is sometimes that a boiler cannot be repaired, we try to minimise the customers inconvenience and install a new one as quickly as possible. Glad to hear you are happy with our service.
