“Certified Energy is a preferred supplier for ESD services for the last 4 years. Always had a good experience and appreciate their alternative solutions to help reduce some double glazing for our client.”
“I have tried several ESD firms and I have come to the conclusion that it doesn’t get much better than the easy and smooth service that Certified Energy has provided to us repeatedly”
“Iris and the technical team were really helpful every step of the way. After the Section J report they recommended a JV3 passing solution to help reduce the double glazing on the Western elevation which did the trick, great job on this one look forward to using again.”
“Certified Energy completed an assessment, energy efficiency rating and certification on a 9 unit envelopment for us. The work was completed on time, professionally and at the right price. I am happy to recommend them and I will be using their services again.”
“Have been working with certified energy for over two years now and remain impressed with how I have been able to reduce glazing cost on most projects. Creative team and easy to deal with”
