Highlights
"Mark & Billy were absolutely brilliant from start to finish during our house renovation. They handled all the electrics and did an outstanding job. Their work was neat, professional, and completed to a really high standard. They were also incredibly friendly, approachable, and always happy to explain things or offer advice when needed. Nothing was ever too much trouble, and they made the whole process stress-free. I wouldn’t hesitate to recommend Mark & Billy to anyone looking for reliable, skilled electricians. Thanks again for all your hard work!"

Smart checks
Before you hire an electrician
In England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations — confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done — it is your proof the work is safe and compliant, and you will need it if you ever sell.
Confirm they cover your area and can actually come out in your timeframe before anything else.
Read recent reviews for reliability and turning up on time — not only the quality of the work.
