John and his guys installed a fantastic Mitsubishi heat pump for us back in September. We have now been through the worst of the winter (hopefully) and I can report that it does everything we hoped it would and that we would never want a gas boiler again. We had a couple of other quotes before deciding to appoint John to carry out this installation. It was clear that John has a high level technical understanding of this technology. He spent quite a bit of time carrying out the initial survey and answering our many questions and in the end he was the only installer who gave us the confidence to take the leap and ditch the gas. We would have no hesitation in recommending John to anybody considering getting a heat pump.

John and his team are fantastic! They service my boiler regularly after they fixed it when an error code shut the system down. So I didn't hesitate to contact John when my elderly Mum had several plumbing issues at her flat. They fixed everything and were also very kind and patient with her which both of us at ease. Excellent customer service and response, wonderful team, thank you John!

I recently used Biggs Heat Technologies and was very impressed with their service. They responded quickly, communicated clearly throughout, and fixed the issue to a high standard. On top of that, they provided helpful general advice, which I really appreciated. I’d definitely recommend them to anyone looking for reliable and professional heating services.

Outstanding Customer Service I contacted John after another plumber had told me that my heating system would have to be drained in order to fix a leak from one of the pipes leading to my boiler. One of John’s employees (Brandon) arrived later the same day and quickly fixed the problem without having to draining the system. I have already asked John to service my boiler in future and will definitely use Biggs Heat Technologies for all my future plumbing requirements.

John Biggs services and maintains my gas boiler and underfloor heating system, and has done so for several years. His standard of workmanship, rapid response, and proficiency gives me full confidence, and I can strongly recommend him to others for all types of maintenance and repair of gas heating equipment..

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.
