Susan Harrison
Harry is a really nice person & easy to relate to. He responded very quickly when he heard that we had no hot water. The air pump system in our new build has been fitted with many errors. He returned with his excellent electrician & rectified a lot. For the first time, It is working as it should. He is very knowledgeable about the various models of pumps & systems. We intend to call him back to do a complete refit. We can recommend Harry & Sussex Renewable Heating with all confidence.

Harry is professional, friendly and gets the job done! He fit me in last minute and sorted the problem within a very short turnaround. . We have used his services now a few times and he communicates well too unlike some who come and provide a quote only to receive radio silence! I would highly recommend him!

Harry serviced my ASHP and did a great, thorough job. Took time to explain some functionality and really friendly too. Would definitely recommend
Nigel Murphy
Arrived on time very efficient in carrying out the service, also very knowledge on the subject of heat pumps was a tidy and clean worker. Would have no trouble in recommending Harry from Sussex Renewable Heating Ltd.
Lee Gander
Needed someone to service the air source heat pump and Harry was great to deal with. It was easy to arrange the appointment, he arrived on time and was very knowledgeable and helpful. Its nice to have someone locally who can now keep an eye on the system going forward.

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.
