Cinergi installed a full solar system, battery storage and EV charger for us. From the initial consultation with Shannon and James, to the final installation from Kieran, Dan and Josh, the team demonstrated exceptional knowledge and clear, consistent communication throughout the entire process. Shannon, Kate and James were always quick to respond to all my questions. Since the installation, the level of support and communication has been amazing. Kate is an outstanding Operations Director - she genuinely cares about customers long after installation is complete. The SigEnergy system is performing brilliantly. I have recommended Cinergi to several people already and I wouldn’t hesitate to recommend Cinergi to more. It’s rare to find a company that combines technical expertise with such a strong commitment to customer service.
A major piece of work was well done with minimal disruption. Our installer, Charlie, was willing to allow us to say exactly what we wanted and was always willing to go the extra mile. He coped with the extraordinary high heat levels as well!
Adam and Dave were the 2 leads for our Ariston air source heat pump, in June 2026. They were both hard workers and very polite and capable. The whole process went very well and we are happy with the new set up. We had 10 radiators fited at the same time. Many thanks.
Thank you Jack for getting our garage roof solar panels& battery up, running & explained. We appreciated your neat cabling on the garden wall and how tidy you left everything. Speedy & efficient.
Jack, Dan and Louis did an excellent job installing our solar panels and battery . Polite and helpful, checking in with us each step of the way. Installed 13 panels in one day. Explained the App to us. Very pleased indeed.
