We have just had 64 extra panels added & a new inverter/replaced to an existing system. Callum and team did an exceptional job, worksmanship is 5 star. The system was designed and all done in-house. Everything from start to finish was profesional, quality of products etc.

We are extremely pleased with the solar system and it is performing as expected. Our neighbours are very impressed with how the solar panels sit and line up uniformly on the roofs.

I would like to thank all the team for the great job they have done and I highly recommend the company and the team. It was a real pleasure working with people who are experts in what they do. 5 stars plus.

I couldn’t be happier with the service I received from Complete Solar Installation. From the initial consultation to the final installation, the entire process was smooth, professional, and hassle-free.

If you’re thinking about going solar, I highly recommend Complete Solar Installation.

Callum and his team have completed our electrical work replacing an older main fuse box and moving it, put lights in our garden and electrics at the top of our garden in a summer house. They also moved our cooker point in the kitchen and added additional sockets. Callum also fitted our cctv system. I would have no hesitation in recommending Callum and his team at all.

Having researched solar panel and battery installations, I reached out to Callum Frogley to discuss the requirements. He very promptly provided quotes covering the various options available to fit, I chose Callum and the team to undertake the work. I highly recommend Callum and his team for the work completed and the standard of finish.
