“Dan was tasked with substantial rewiring and additional electric services provision when our old house was upgraded. His solutions were neat, unobtrusive and incorporated the best components. Some of the work required overcoming awkward problems, especially with fault tracing and rewiring of old systems in difficult positions and in the garden. His advice is calm and professional and he supports his finished work. Highly recommended.”

"I called in The Big Green Electrical Company to change the lighting in our barbershop. After explaining to Dan what we were looking for, he was extremely helpful with the advice he gave and offered some brilliant ideas I wouldn’t have thought of myself. The work itself was carried out over a weekend when the shop was shut and the results are amazing!! I can’t recommend Dan highly enough. Smart, professional and extremely knowledgeable. All in all a fantastic experience".

“I now have warm toes again! Dan from The Big Green Electrical Company replaced the broken thermostat for my bathroom underfloor heating yesterday and I now have a lovely warm floor. He managed to find a replacement that fitted in the same slot as the old one, so no mess, plus the new one is much easier to use. I would thoroughly recommend them.”
