Last week two smart young men arrived at our house to add to our Solar installations, they were professional and experienced. The work was done and then tidyed up. They explained everything in plain English and then asked if we were happy and understood everything. I highly recommend TGP to anyone wanting help with Solar installation or aftercare. Our two engineers were really superb. Thank you Joe and Lee it was a pleasure to meet you. Thank you TGP for all your help over the years.
