I felt compelled in writing a few words of praise for your company, Certass, and yourself. As an Energy Rated Installer AGS had the choice of three companies, including Certass, to register our Energy Rating Labels. I would like to say how pleased I am for choosing Certass. The service provided has been exemplary. I know I had a lot of questions and requirements and I am very happy in the way you dealt with them for me. I would like to commend and recommend Certass to any potential installer who is considering who to choose to register their Energy Labels with.
