We installed a 5kW system with a 12 panel array and a GivEnergy 9.5kW battery storage and are delighted with the result. Not only is our system efficient and practical, but was also delivered in a professional and timely manner. Workmanship was exemplary throughout and carried out to exacting standards.

I was recommended AS Mechanical and Electrical by a friend who knows the market. I did not go into the process lightly and among other things, asked the firm to provide evidence of their competency.
