RES (Devon) Ltd installed a smartswitch for our solar / hot water installation. They were helpful, professional and good value. Chris Rollins gave us excellent advice and Scott installed. Both were very knowledgeable and during istallation they looked after our house as though it was their own. Really impressed and will be back the next time we need some help with our Solar / Biomass systems. Thanks Guys.

We are a customer of RES Devon Limited and we can highly recommend them based upon the exceptional level of service we received when their team designed and installed the solar energy heating and hot water system for our renovation project. We were particularly impressed with the expert advice offered prior to installation which enabled us to make an informed decision on what type of heating system was right for us. The installation team were professional on site and they were prepared to make the extra effort, evident from their high level of workmanship and their attention to detail. The end result is we have a heating and hot water system which, over the last year, has exceeded our expectations in performance, comfort, ease of use and in energy efficiency. We would recommend RES Devon Limited to anyone considering a renewable energy system for renovation or new build projects. Andy & Tina

RES Devon fitted solar PV, Tesla battery and a ground source heat pump. From initial enquiry, ordering, fitting and installation we have been delighted with everything the RES Team have done. Thoroughly professional, totally trustworthy and project management were all excellent. Wouldn't hesitate in recommending this company.

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.
