Average rating: 5.0 out of 5
Review by Susan Porter
on 29th October 2026
"Martin and Callum did a fantastic job rewiring an old terraced house with ancient wiring. They worked quickly and efficiently and to an extremely high standard, they are true professionals. Martin even took the trouble to advise me on other housing issues which was extremely helpful. I wouldn't not hesitate to recommend them and plan on using them for future jobs. Thanks Martin and Callum"

"Top marks all round for a full house rewire. Martin and Calum were punctual, worked fast, and communicated clearly throughout the entire process so I always knew what was going on. The prospects of having our old Victorian house rewired was daunting, but Martin found way to run the new wires with minimum affect on our rooms and features such as picture rails and cornice. This was a big job with floorboards being lifted and furniture moved, but Martin made sure any holes were filled, fixed and repaired. A brilliant job done, I wouldn't hesitate to recommend them or use their services again!"
