Just had Cinergi install solar panels on the roof and a Tesla power Wall three in the garage. The installation team did an excellent job Jack and Alex we’re really good at explaining what they were doing, always asked questions in terms of positioning and installation prior to going ahead. When it came to the software and app Jack’s explanation was very straightforward and helpful. The electrical installation and cable rooting was also spot-on. I Iwould definitely recommend Jack and Alex from Cinergi, they did a great job. As this was part of a whole house renovation there was also a lot of communication with Kate at head office agreeing dates and also chasing Tesla to deliver a very large and heavy power cable, which did take awhile. But we were kept in the loop by the team.

Cinergi have just completed installation of a solar / battery / EV charger system on my home. I’ve been discussing various options for a few months, and their technical / sales staff (George and James) spent a lot of time explaining how it could work, and talking through options. They were very clear, and helpful, and not at all pushy. When we decided to go ahead, they were efficient in getting the paperwork out, booking the project in and making all the arrangements. The scaffolders did a good job getting set up, and the installation team were excellent. They came on time, built the project that they were meant to do, and finished on time. They were really impressive in looking for (and finding) efficient routes to run the cables - in the loft space and finding a way to get into the space under the ground floor to run a cable under the house, so that overall the system installation had minimal visible impact on the house. They commissioned it, explained how it all worked, and set up the apps very clearly. They left a good clean job, and everything seems to be working really well. A shout-out for Alex fitting the panels, Jack the electrician, and the two apprentices Louis and Ben. Well done to all !

We recently used Cinergi to replace our gas boiler with a heat pump and solar panels. The installation was excellent and the team friendly and knowledgeable. Special thanks to the two young men who put the solar panels on our roof in torrential rain without complaint. And also a big thank you to John, and Carl, Jack, Alex and Louie. James, Elliott and Sophia gave us the confidence to use Cinergi.

Just had a heat pump installation and the team did a great job from start to finish. They were able to design a system that fitted into our relatively small mid terrace house (which a large energy company were unable to), and deliver it soon after the order was placed. They worked quickly and considerately, and accommodated our requests as best they could. Thanks to Adam, Dan and the whole team including the office team who were very helpful all the way through. Would definitely recommend Cinergi to others.

Jack,Ben and Josh were brilliant and erected 18 solar panels, battery x 2 , Zappi car charger and generator input without a problem. Cables are out of view. James provided quote at outset and was very knowledgeable. Great communication with office. I chose Cinergi as a friend had solar and battery 1 yr ago and all went seamlessly . Neighbours used a different company which went bust within 6 months and now they have no backup. Cinergi were the most expensive price , but you get what you pay for. Lots of cowboy companies out there so be careful in choosing.

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.
