Jason responded to my request for a second opinion promptly. I was "cold called" by a company offering a free check on my 6 year old solar energy system. They then tried to tell me the system was working at 72% capacity, that they would replace my inverter and install optimisers for £5,500 but special offer if i signed a contract there and then for £4,500. Needless to say I declined. I contacted Which? Trusted Traders for advice and was given Jason's name. He checked my system, found no problems and told me if anything it was performing better than expected. He also gave me his quotes for the work the other company had said needed doing- a fraction of the cost! Jason was efficient, clean and thorough and as the other reviews say courteous and a very nice man. If I ever need anything to do with solar energy I will be ringing Jason.

5 of our 20 solar PV panels were 'down' – Jason renewed the whole system with a new junction box and individual optimiser on each panel, plus cleaned and pigeon-proofed our PV and solar thermal systems and roof. Everything is working perfectly now. And all the work carried out with a smile – even travelling 2 hours to Kettering was no problem. Recommended.
