RT Solar are the best at what they do and the best prices I can find. After listening to bog standard installs and sky high quotes from the national companies, I found RT Solar. They listened to my unique needs, as someone with two EVs and a smart home with lots of kit, they gave me a solution that I liked. When they gave me the best price I’d seen, I liked it even more. My original install was for a 20 panel system with a 5.2kw battery. This cut my energy bills by 75%. I recently had a larger battery installed with an iboost to power my hot water with excess energy, and since the install, I’ve barely taken any grid electricity at all, I’d guess a 95% reduction on my bill. I’m very pleased with the work carried out, exceptionally neat and the best looking panel install I’ve ever seen. My wife was concerned they would be ugly, but frankly they look so neat that even she’s happy with them. I’ve had many neighbours ask about them too, impressed that they look so good! So should you use RT Solar? Yes. They offer great solutions at fantastic prices. I’ve now got a veritable power station, so will sadly probably have no further need for their services, but if I do, then I’ll go directly back to them.

I had an air source heat pump installed by RT Solar. It was an ordeal and I do not recommend them. They are clearly primarily an installer of solar panels, on which I cannot comment. Air source heat pumps, however, are complex systems, for which RT Solar (and probably many other suppliers out there) do not have the skills and capabilities, so please do yourself a favour and find a heating engineer, not ordinary plumbers. Please do not engage RT Solar to install an air source heat pump.

I purchased my solar panels in 2022. Quality and hassle free installation. Everybody from start to finish were friendly, knowledgeable and explained how everything worked. My system generates more than what was predicted. My system generates so much that it offsets all of my gas and electricity bill for the whole year and I have export credit left over! Best Investment Ever!

Everyone at RT Solar has been very helpful. We were not happy with our previous plumbing service and we contacted RT Solar for pipe chasing in the wall and installing a radiator and towel rail. They were very prompt and professional as well as helpful with great advice. Shane and James were very good and didn't leave until all was perfect.
Sandy Bear
Fabulous experience with RT Solar, Ivan explained the system, quoted a good price with no fuss, and was always available to answer our questions. Project Manager Sandy was in regular contact and organised the fitting which went exactly as planned. Everyone involved was efficient, courteous and helpful. Couldn't have asked for more. Highly recommended

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.
