“From the first contact, we were very impressed with Full Power. Gabriel’s survey was professional, friendly and informative, and the quote was competitive. Installation was completed within three weeks with regular updates throughout. The whole team worked quickly and professionally on the day. We highly recommend Full Power and are now using them again for our air source heating.”

“Great solar and battery install from Full Power. I wanted a physical survey due to our complex roof layout, and the team were very helpful and flexible with the panel and battery locations. Installation was completed earlier than expected, and the team worked hard to finish everything in one day. A really neat and tidy job with a great clean-up afterwards.”
