“Gareth did the rewiring for our new extension, all the outdoor lights, installed all our electrical appliances and undercounter strip lights. I would have no hesitation in recommending Gareth, and have done so to friends. He's professional, tidy, attentive & really good at his trade. Nothing was too much trouble when we made last minute changes. Will definitely be using Gareth again when we need him.”
