I'd like to thank so much to Robat and his team on the heat pump, solar panel installation, they have just completed on my house. It's overwhelming and life changing the work they've done. The team where very professional, hard working and so polite. Happy to answer any questions I had. I really appreciate you managing to complete 90% of the work before Christmas. Has made such a difference to my quality of life. Also Robat replied to my messages over the Christmas period to help me. Which i didn't expect. Very grateful for that. I would highly recommend the company. Fantastic team ! Thank you so much for everything Claire & Sapphire Cae Merched
