What Our Customers Say

Rated 5 stars across Google and recommendations. Real customers, real feedback.

Gary rewired our entire ground floor after we discovered old cloth-covered cables. He explained everything clearly, stuck to the quote exactly, and left the house spotless. Couldn't recommend more highly.

Had a fuse board that kept tripping on a Sunday afternoon. Diamond came out within the hour, found the fault immediately, and had it fixed before dinner. Fair price for emergency callout too.

Used Diamond for our rental property EICR — fast turnaround, thorough report, and they even talked the letting agent through the remedial works needed. Very professional outfit.
