My experience with Infinity Renewables has been consistently disappointing. The most serious issue was the original installation, which was carried out to a substandard level and required a complete refit. Tiles were broken, wiring and conduit were left untidy, and the work appeared rushed (the roofer had a party to attend that night). Even after the refit, issues remained: my roof was left with slipped tiles and daylight visible through the loft, the marks you can see on the tiles are where the roofer either wiped his hands to get rid of the glue or was on his shoes, also note the mismatched tiles on my brand new house, the backup system wasn’t commissioned correctly and resulted in an engineer from Bexie attending - Infinity hadn't toggled the switch for the backup to work. I also discovered errors in my contract and EPVS validation paperwork. When I provided feedback through EPVS, I received an inappropriate text message from a member of staff, which I found unprofessional. Another serious issue was the incorrect commissioning documentation submitted to the DNO. For several weeks I was told this could not be changed, and only after escalating through the finance company, MCS, and EPVS and issuing a formal 7-day letter did Infinity Renewables resolve it. To their credit, the company returned to repair my roof on 22/08/2025 and again on 30/09/2025, and they provided two additional solar panels and a half-price battery as compensation. I gave them a draft of this review, I was contacted directly by James at Infinity Renewables who assured me that my experience had been taken seriously, that staff training had been implemented, and that I would have him as my direct escalation route for any future concerns. Unfortunately, since then I have experienced further documentation errors, and the promised escalation contact from James has been unavailable and unresponsive. Despite assurances of improvement, the same issues with accuracy, communication, and accountability continue to recur. My confidence in the company has therefore declined further. While they eventually resolved some of the earlier problems, the repeated mistakes and lack of reliable aftercare demonstrate that the underlying issues have not been properly addressed.

Great start, but clearly a victim of their own success. The installation was really smooth, and I've had it for 2 years now, however the number of problems that have occurred since. The inverter has been replaced 3 times, the batteries have been replaced twice. Their phone lines are open 9:30am - 5pm, and the person on the other end is always really happy and polite, but that doesn't actually fix the problems. They'll then happily schedule an engineer to visit in a months time. A month (or more) without the solar power. Those glorious sunny days, wasted by inefficiency. The latest issue is that phoning them up to rearrange a booking, I gave them a month's notice that the date wasn't suitable. It gets to 3 days before that original date and I get an email going "We're turning up on the original date!".

Infinity installed the home solar battery neatly in a porch by our kitchen door. The Inverter is installed above it. The team were polity and friendly and didn’t mind our dogs trying to help. There was no mess. They showed us how to use the app (there is nothing we need to do). We now enjoy the electricity storage from or=ur solar panels.

Takes details and then ignores all messages, doesn’t even bother to explain that they don’t want to do the contract . It may be better to just say that it’s better for me to go elsewhere . I’m glad that I didn’t go ahead with them as if this is before , what will it be like during the fitting of the job .

Infinity installed our solar panels through the Solar Together scheme and they were excellent. Great comms. Great kit. Nice people. Will defo come back to them when I want to add a few more or a battery!

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.
