ThermHeat installed a new Worcester Bosch boiler system in our utility room and performed a power flush of the installed system. Everything went smoothly and to time and we were kept updated regularly on progress. The area was kept clean and all rubbish was removed afterwards. A great job performed at reasonable cost. Thoroughly recommended.

This fim came up trumps on Checkatrade with highest reviews so I contacted them 1st & as it was Xmas Eve b4 the holidays & it was cold & my Mum is vulnerable. I contacted Therm Heat Ltd. the lady who answered was Fantastic ! She said they were booked out for the day but if an engineer finished before 4, she'd get them to come to us. Then she asked me to describe the problem & she talked me through fixing the problem myself! That the water pressure had become so low, that stops it working, I didn't know! We stull need it's annual servicing tho' as it's overdue! Thank You & Bless! Most impressed

Active incorporated business
Therm Heat Ltd is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 13 years on the register also points to an established business rather than a brand-new one.
