Excellent service from start to finish. Nathan arrived on time, clearly explained the problem and fixed it efficiently leaving the area clean and tidy. I also want to mention Louise in the office that understood the work that needed doing and was transparent with the price for for the job she was so helpful and booked me in for the first available time slot. I highly recommend and would definitely use them agin.

Therm Heat Ltd is an excellent company to do business with. From getting a quote and having a new boiler fitted the process went without any problems. Nathan is very knowledgeable, helpful and extremely customer friendly, he fitted our new boiler in one day, had all the rubbish cleared and cleaned up after the install, he fully explained how everything worked. All communication with the office was great, kept us informed at every stage. I have no hesitation in recommending this company.

Thermheat installed our new combi boiler in a new position in 2020 and have serviced it ever since. The service has always been excellent. Steve and the team are fantastic, friendly, professional, reliable, and extremely knowledgeable. Everything is explained clearly and the work is always completed to a very high standard. I could not recommend them enough.

After deciding that we needed to replace our boiler, we asked Therm Heat to quote for the job. Steve came to the house, checked out the existing boiler and radiators and supplied a quote a few days later. We were happy with this and their availability to do the work, so went ahead with the quote for the boiler replacement and a power flush. Before the actual replacement day, Steve came back to perform a site survey to ensure he had everything for the job which was reassuring. The boiler replacement and power flush went very smoothly. The power flush itself was quite noisy but Steve had warned us about this in advance. We particularly liked the fact that both Louise and Steve kept us updated during the process and we were involved in various decisions during the fitting of the new boiler. Steve was very professional and very very tidy, ensuring that the older boiler and other debris were taken away and also that all surfaces in the utility room were hoovered and wiped down after the job was completed. He also worked solidly throughout both days and ensured that we had all the radiators and hot water back by the end of the first day. We can definitely recommend Therm Heat and will be using them to service out new boiler in the future.

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
