I had a Vaillant heat pump installed by Ectotherm in November last year. I was really pleased with the whole process. From start to finish, Chris explained everything very clearly, from the quote stage, the actual installation, to the controls when everything was installed, he went above and beyond my expectations. The heat pump is working really efficiently, my house is toastie warm all of the time, it’s really been tested over the winter months and my bills are less! As the company is MCS accredited, I was able to get the government grant of £7500 towards the work. I would, without hesitation, recommend Ectotherm they were excellent.

5 star service! Chris from Ectotherm fitted my new boiler and my bills have improved vastly since. I only wish my house was suitable to have a heat pump fitted. I would recommend them to anyone.

I’ve worked with Ectotherm on several projects and they’ve been excellent throughout. They are highly knowledgeable, thorough in their approach, and consistently clear and communicative at every stage. It’s evident they are passionate about what they do, and I wouldn’t hesitate to work with them again or recommend them to others.

Chris is extremely professional and trustworthy. He has great attention to detail and ensures we have the best possible outcome. I would highly recommend Chris, rare to find someone who is this reliable and starts and finishes the job to time.

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.
