Decided to invest in CCTV cameras and security lighting around our home and spoke to Mark at GDH3 about the different systems. He recommended a system that linked up to our WiFi and enabled us to keep an eye on our property via our phones from anywhere in the world. The price quoted was very competitive. The system was up and running within the day. We are extremely happy with the work carried out and would highly recommend GDH3 to anyone.

Mark was recommended by our builder for all the required electrical work for our kitchen extension. Mark is extremely professional, reasonably priced and a friendly person to have working in the house. He is thorough in his work, explaining in non technical terms anything that we weren't clear about. He ensured that he left the house clean and tidy, and even contacted us afterwards to ensure everything was to our satisfaction. I would highly recommend Mark and will contact him again should I have further electrical work

Yet again Mark saved the day. He is absolutely my go to for anything electrical. After already rewiring my garden including electrics & lighting to my outdoor kitchen (to a fab standard & on time I might add), he has just saved the day by kindly doing an emergency fix of a broken circuit board (an old problem caused by a different electrician). Thanks again Mark!

I contacted Mark to have an external charger fitted for my hybrid car. He was very prompt to respond and left me as a satisfied customer, so much so that I asked him to quote for some further works to my home, i.e. replacing a broken extractor fan, work to my burglar alarm system and fitting a new external light. Again the quote was very reasonable and the work done to my complete satisfaction. I'd have no hesitation in recommending Mark to anyone. The thing I liked in particular was that Mark would keep to his word. He sent me his quote when he said he would, when I told him the quote was acceptable, he'd then confirm when the work would be done and then he'd turn up on the agreed date and carry out the works in a professional manner. If you need any electrical work doing, Mark's your man
