Average rating: 5.0 out of 5
Review by George
on 22nd June 2026
"I would have no hesitation in recommending Dominic and Phase One Mechanical & Electrical Ltd. From the initial site visit through to completion, Dominic was professional, knowledgeable and a pleasure to deal with. He took the time to assess the installation properly, explain the available options, and recommend a sensible long-term solution rather than simply the minimum required to obtain a satisfactory EICR. Communication was excellent throughout, the workmanship was of a very high standard, and the new consumer unit installation was completed neatly, efficiently and with great attention to detail. Everything was tested, certified and left clean and tidy. It is refreshing to find an electrician who combines technical expertise with excellent customer service. I will certainly use Phase One again for future electrical work and would happily recommend them to others."

"I hired Phase One Mechanical & Electrical Ltd to upgrade and replace a 1970s consumer unit to meet current regulations. They provided a quote quickly and scheduled the work within a week. The job was completed on time, to a good standard, and stayed within the original quote. They also sent the EIC and EICR the same day. I’d happily use them again and would recommend their services. Thank you!"
