Trusted by homeowners across Dorset, Hampshire and Wiltshire for integrated renewable energy solutions.

"I recently had my solar system installed by Renerji and I couldn't be happier with the result. The team were incredibly careful and clearly took pride in their work. They took the time to explain how the system works and made the whole process feel straightforward and stress-free. The aftercare has also been fantastic. I would absolutely recommend Renerji and have already recommended them to several friends."

What Our Clients Say

Hear from homeowners across Dorset and Hampshire who've switched to clean, integrated energy with Renerji.

The initial consultation was refreshingly straightforward: no hard sell, just honest advice tailored to my setup and energy goals. Installation day was smooth and well-organised. The engineers arrived on time, worked efficiently, and left everything clean and tidy. What really stood out was the communication throughout. Even after installation, they've been helpful guiding me through export tariffs and system optimisation. A genuinely first-class service from a team that delivers on what they promise.

Josh STrustpilot

We recently had an Enphase solar system installed and I couldn't be happier. Liam and his team were absolutely fantastic from start to finish: friendly, polite, and incredibly hard working. Everything was done very neatly and professionally, finished right on time as promised. Liam also went the extra mile to walk me through the full setup once everything was installed. I wouldn't hesitate to recommend them to anyone considering solar.

Nicholas GTrustpilot

Very knowledgeable team. They installed the maximum system my roof would allow to get the most returns we could. Very happy with the service provided. Thank you Renerji!
