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!

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 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.

Mark recently completely replaced my old outdated fuse board with a modern equivalent at my business premises. He kindly undertook the work at a weekend so as not to disrupt my work. His workmanship was excellent and the service received was very professional. The work area was cleaned up well so no mess which I much appreciated. I have no hesitation in recommending Mark for any electrical needs.

Mark called in advance of the installation sending me a detailed tick list so that everything went smoothly on the day. Like everyone I am new to EV technology so its early days . I had not taken delivery of my vehicle before the installation was carried out but Mark gave me a complete run through in how to connect and operate . The installation and quality seems to be spot on and all working perfectly.
