What Our
Clients Say
"Absolutely first-class work. Had a full consumer unit upgrade done — tidy, efficient, and fully certified. Explained everything clearly and the price matched the quote exactly. Highly recommend."
"Called at 9pm with an electrical fault and DM Electrotechnical were there within the hour. Sorted the problem quickly and charged a very fair price for an emergency call-out. Will use for all future work."
"Used DM Electrotechnical for a full rewire on our 1930s semi. The work was immaculate — every cable neatly run, all plastering made good. Passed the EICR first time. Genuinely outstanding tradesman."
"Had smart lighting installed throughout the house. Really knowledgeable about the systems and took the time to set everything up properly. Clean worker, great communication throughout the job."
"Commercial fit-out for our new office — structured cabling, emergency lighting, and full power install. Completed on time and on budget. Professional from start to finish."
"Needed an EICR report for a property sale. Booked quickly, turned up on time, and had the certificate to me same day. Simple job handled with total professionalism."
