What customers say

Based on genuine customer reviews

Evergreen Power UK – Solar Panels & Battery Installation Specialists draws a mixed picture from the accounts left by customers in and around Croydon. Several reviewers describe the quotation process as straightforward and the initial installation as quick, with scaffolding and electricians arriving when expected, and panels fitted neatly and centred on the roof.

Praise recurs for the friendliness and punctuality of install teams, with named staff such as George, Tom, Mickie and Roland singled out for cheerful, polite work and for taking care with existing roofing. Customers repeatedly mention clear explanations of how the solar panels and battery storage operate, alongside the ability to monitor output through an app, and note lower electricity bills once systems were running. Something that features in review after review is the difficulty some customers faced after installation, including a reported roof tile breakage, months of chasing an unresolved complaint, and a battery replacement that was diagnosed but not completed promptly.

Communication before the work is generally described as regular and timeline promises as kept, but the aftercare accounts describe delays and unanswered calls that left some customers frustrated. Many highlight the speed from order to install, while others felt the sales approach was pushy and the follow-through on battery fitting fell short.

We got evergreen to give us quote that was fine. Then the lads came to fit the panels and the electrics but there was no electrician to fit the battery 🙄 a few days later a electrician turned up but had no battery 😳. Well a few weeks pass and after been in touch with evergreen and them telling us we're definitely going to come on a Friday of that week no one turned up 2 weeks and the battery turned up with one lad . The battery are very very heavy good job that I'm still fit to help him . Well the system up and running know it got fitted in March 26. We are still waiting to sell back to the grid evergreen are not answering are calls 🙄 . Called to day at 1230 .was told the person you need to speak to in a meeting . Again and again . Take it form me i only give a honest review and a truthful response to my experience

Avoid Evergreen Power UK. This has been one of the worst experiences I’ve ever had with a company. They installed our solar panels in October and damaged our roof by breaking several tiles during the installation. We reported the damage immediately, emailed photographs as evidence, and then spent months chasing them with countless phone calls because they simply ignored our complaint. After several months of excuses and delays, they finally arranged an appointment to inspect the damage, and a further appointment was made for today 30.06.2026 between 8:00am and 11:00am. We booked annual leave from work specifically so we could be at home. Nobody turned up. At 12:30pm I called the office to find out what was going on. Instead of apologising, I was told that someone had supposedly visited our property and taken photographs. That is simply not what happened. We were at home the entire time. Nobody knocked. Nobody rang the doorbell. Nobody called. Nobody came. After months of waiting, being ignored, and wasting our time, to then be told that someone attended when, from our perspective, nobody did is beyond frustrating. It feels like they were trying to avoid taking responsibility rather than dealing with a genuine customer complaint. The installation damaged our property, customer service has been appalling, communication has been almost non-existent, and even when they finally arranged to put things right, they failed to turn up. I have completely lost confidence in Evergreen Power UK. If this is how they treat customers after they’ve been paid, I would strongly advise anyone thinking of using them to think very carefully before signing a contract.

Last month, we had Evergreen Power UK install our solar panels and battery. The entire process was smooth, and their communication was excellent. The installation team was not only friendly but also diligent in completing the job on schedule. They left our home tidy and took the time to ensure we understood how the system works. The app is user friendly, and it's wonderful to see the amount of energy we're already generating!

From start to finish, our experience with Evergreen Power UK was incredibly smooth. They communicated with us regularly, stuck to their timeline, and delivered exactly what we had discussed. The installation team was not only professional but also very friendly. The system is working perfectly, and it's great to be able to monitor everything through the app. Overall, it was a completely seamless and stress-free experience.

We had an excellent experience with Evergreen Power UK. The quote was simple to understand, and the installation went off without a hitch. The team was very friendly as well. Before they finished up, they took a moment to explain how everything operates, which really boosted our confidence. Since then, the system has been running smoothly, and we've noticed a decline in our electricity bills. We're really happy with our decision!

Evergreen Power UK did an excellent job with our solar installation. From the very first survey all the way to the completed setup, everything was well organized and professional. The team arrived on time, worked efficiently, and made sure to keep the area clean. Before they left, they took the time to explain how the system works, which was really helpful. We've already noticed a reduction in our electricity usage, even in just the first few weeks. Overall, it was a fantastic experience, and I would gladly recommend them to others.

I recently had an installation by UK Evergreen Power, and I couldn't be happier. From the initial consultation to the final setup, the team was incredibly professional. They took the time to answer all my questions and concerns, and their aftersales support has been just as responsive. The installation itself was surprisingly fast and smooth—they were completely finished by lunchtime! The electrician was a huge help; he guided me through the SolisCloud account setup and explained the system clearly. He even offered a dedicated office contact for further app support, though I managed to find the extra details I needed online. It’s great to know that level of support is available if needed. Highly recommended!
