Mark fitted LED panels to our offices. The work was carried out over three phases and was done to an excellent standard with minimum disruption. The new lights provide a brilliant white light with a significant energy reduction. After completion the offices were left clean and the old units were disposed of responsibly. He was a pleasure to work with and I wouldn't hesitate to recommend GDH3.

We first had Mark to fit us a security light a year or so ago. He was very reliable so we decided to have him again this year to help with a complete house renovation. Mark rewired the house and helped with all the electrics in the kitchen as well as a new alarm system. He turned up on time every day he came and stayed extra at night to do some extra jobs I had asked him to do. He always left the house tidy and mess free. We had an issue with an electric garage door after the zapper had been lost and he researched what was best to do with it. As well as electrics he has helped advise me on other matters to do with my renovation and nothing was ever to much trouble for him. I can 100% say that I probably could not have done this project without him. He has been amazing. Thank you

Mark came to do the electrical work in our new extension and a couple of small jobs elsewhere. He is a lovely man, very professional, clean and tidy, did a fabulous job. Punctual, honest and reliable, happy to leave him in the house and would certainly recommend him to others.

It's refreshing these days to find someone you can trust and who doesn't let you down. I am so pleased Mark was recommended to me as the work he has done has been outstanding. He came up with solutions on both occasions I have used him and I would not hesitate to pass on a further recommendation for such a professional and friendly person to deal with. Thank you.
