Mark came to give us a quote very promptly after I spotted his recommmendation on my work e mail. The quote was very reasonsbly priced and a convenient work date given. When looking at our faulty bathroom fan, he pointed out that the brushed steel sockets recently replaced (DIY) weren't safe.This was all fixed and made safe quickly and efficiently.We have since called Mark back to add some further sockets during some refurbishment, and again he has replied promptly, provided a very reasonably priced quotation and arranged a date to carry out the work without delay.I would not hesitate to recommend this company.

I have used GDH3 to undertake work at my home and also my office. We have always found Mark to be reliable, and the quality of work undertaken to be excellent. I have no hesitation in recommending Mark Shepherd/GDH3.

Mark supplied and fitted outside security lighting, replaced some interior lighting and fitted an electric fire for me. He is extremely helpful, flexible and professional. He was recommended to me by a work colleague and I would have no hesitation in recommending him to others.

Mark Shepherd installed a new fuse box and completely rewired my kitchen in readiness for a new kitchen being fitted.I had previously been given some advice from another supplier but was not confident of the service he claimed to provide, I turned to Mark who completed a full survey and offered advice, which turned out to be contrary to that of the previous supplier - it was very reassuring and Mark completed the work very quickly and efficiently, delighted with the service he provides!

I purchased an electric car and it was Nu-World energy that arranged Mark to install the charger at my home. I can honestly say that I think Mark is one of the most politest and professional tradesmen that I have ever come across. Mark also prepared so well in advance that it was impossible to fail the task. Even the weather could not stop him. Mark managed to get from near Sheffield via Wales to Wiltshire on the snowiest day of the year. If you want a job done good, this is the man to hire. Well done Mark.

Mark was recommended via a work colleague and has completed several domestic electrical jobs for me. He has gone out of his way to accommodate my requirements - well beyond what might reasonably be expected - and works as unobtrusively as he is able, even bringing his own vacuum cleaner! The standard of his work is excellent and I have no hesitation in recommending Mark for all aspects of his service.

I would recommend Mark to any of my friends or work colleagues and will definitely use him in the future.Many thanks.
