“Absolutely superb experience. John was punctual and worked extremely hard during some very hot days to get everything done to a really high standard. Was very imaginative in working out the best solution to our needs rather than taking the easiest route. I had total trust in his capabilities and advice. He explained what he was doing clearly and authoritatively. Really impressed with the work he has done and would be delighted to ask him for more work. Couldn't recommend highly enough.”

Highlights
“Came last minute to help me find a fault on my mains circuit. Quickly tested all sockets and refitted wires and diagnosed the problem at a reasonable last minute price (125£ for 2hrs work in weekday hours as a last minute request) Professional well spoken and knowledgeable. I shall rehire John for more work down the line and send on recommendations.”
“Wouldn't hesitate to recommend John, he did the work he quoted for, turned up when he said he would, and came back as agreed. Good quality workmanship, knowledgeable and a pleasure to deal with every step of the way.”

Verified by CheckatradeFull rewire of our house and outside office
John is a highly capable electrician and a great professional. There is no other electrician I’d consider for the job, no matter how big or how small. For the rewire we agreed what had to be done and John worked through first and second fix, being very flexible around other contractors and always setting certain circuits live at the end of the day so the place remained habitable. John is also one of the most considerate tradesmen, always sweeping up and being respectful once new flooring had been laid. John is also a good communicator, ensuring to update on a daily basis if plans change.

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.
Check the electrical registerIn 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.
