Client Testimonials
Sustainergy have installed panels on two houses I have owned each time they have been excellent, on time, clean, efficient and the installations have stood the test of time. I would have them again.
K. Barnard of Haverfordwest
When we first installed our wind turbine some 6 years ago Bob got us comfortable with what needed to be done. He was well organised, clean tidy and professional. He has continued to offer exceptional customer service in his helpful attentive style. A pleasure to recommend Bob with his great skill and knowledge of all things sustainable.
J. Loo of Eco Barns, Mathry
Bob at Sustainergy recently installed a 4 kW solar PV system on our roof. He took the time to design the installation around our existing velux windows to give us a really tidy look to the roof and the installation went very smoothly. We are very happy not only with the work but also the quality and specification of the different components used. I would highly recommend this company not only for the excellent service that we have received, but also for what I think is very good value for money.
