What Our Customers Say

“Had our consumer unit upgraded by Onyx and the whole experience was brilliant. They were punctual, professional and left everything absolutely spotless. The new board looks great and I feel so much safer knowing everything is up to date. Highly recommend.”

“Really knowledgeable and reliable. Our RCD kept tripping and two other electricians couldn't find the cause. Onyx traced it to a damaged cable under the floorboards in 20 minutes. Sorted it quickly and explained everything clearly. Excellent service.”

“Used Onyx for a full rewire on our 1960s semi — competitive price, minimal disruption and exceptional quality. They worked neatly, kept us updated throughout and were finished ahead of schedule. The new consumer unit and wiring is first class.”

“Had a 7kW EV charger installed on the driveway. From quote to installation was less than a week. Tidy cable run, smart charger set up and working perfectly. They also handled the OZEV grant paperwork. Would definitely use again.”

“Booked an EICR ahead of renting my property. Very thorough — the report was detailed and clearly explained. Two C2 items were identified and they came back the following week to sort them at a fair price. Everything sorted within 2 weeks.”

“Had 6 additional double sockets and 4 new downlights fitted in the kitchen and dining room. Really neat work — you can barely tell where the chasing was done. Professional throughout. Great value for money.”

“Onyx installed underfloor heating mats in our bathroom and en-suite. Arrived on time, completed both rooms in a day and left everything clean. The thermostats work perfectly and the floors are lovely and warm. Really pleased.”

“Had a full garden lighting scheme designed and installed — pathway lights, uplighters and a new external socket. The planning was done carefully so we got exactly what we wanted. The garden looks amazing at night. Couldn't be happier.”

“Consumer unit was 30 years old and needed replacing urgently after our EICR. Onyx came within a week, completed the job in a day and provided all the certificates same day. Very professional, very reasonable. Highly recommended.”

“Had a full electrical supply run to my garden room — armoured cable, sub-board, sockets and lighting. They quoted fairly, turned up on time and the quality of the work is excellent. Everything was certified and Building Control was notified. Brilliant service.”

“Needed mains-wired interlinked smoke alarms for my rental property before a new tenant moved in. Onyx installed 4 alarms and a heat alarm in the kitchen in a single visit. Fast, professional and competitively priced.”

“New kitchen installation required new circuits for the oven, hob, dishwasher and extractor fan. Onyx did all the electrical first and second fix and coordinated perfectly with the kitchen fitter. Reliable, tidy and great value.”
