I wanted to insulate the walls of my home. Found The Green Deal Wales online. They gave me a lot of confidence when I spoke with them over the phone. They came and did a 2-hour survey of the walls which gave me more confidence in the company. They also got me a grant which covered the full cost of the work. Excellent company 10 out of 10.

The Green Deal Wales came and surveyed the walls of my home for Cavity Wall Insulation. The survey took more than 2 hours, but it passed. Booked it in to be done but the corona lockdown delayed it. Now it’s done and they did a good job. Looking forward to a warmer winter and lower gas bills. Great company.
