‘I have had three major domestic jobs completed by SDG Electrical - a total rewiring of our house with outstanding modern safety features and ambient lighting throughout, a complete remote control garden lighting system installed to a large garden, with outside office and hot tub wired in, and an attic conversion with every possible cable fitted in preparation for all possible future uses.
In all these jobs SDG Electrical staff have been a pleasure to have in the house, and have been creative and extremely considerate.
I never bother with quotes from anywhere else, as I know SDG Electrical will do a thorough, perfect job at a fair price and always on time. They are top of their game.’
