“The shower stopped working, and Sam of J N H Electrical deduced that the shower cable had failed due to being the wrong power rating, causing damage to the shower unit. Sam installed a new shower with the correct cable to the consumer unit, and it all worked perfectly. A very prompt and neat installation, and I would recommend his services to others.”

Highlights
“He is incredibly good and the quality of work is second to none. I've put him in touch with quite a lot of people, I'm glad to say he's done good work for them too. Trustworthy & prices are reasonable too. Have used 3 times over a period of a year. He's always gone above and beyond. He's going to come back soon to sort out my fuse box.”
“Have been using Sam's services for over 5 years, he's the only the electrician that I use now. This is because he is always going the extra mile, such a helpful and nice guy. Nothing is too much trouble.”

Very prompt service and issues solved
Had a few issues with defective light fittings which needed rewiring/replacing. Sam came the day after I called him and he quickly fixed the problems. Fair price. Very happy.

Customer recommends this business
Excellent experience
I called Samuel in the morning about two problems - a faulty extractor fan and light switch - neither of them an emergency. He arrived the same day and in less than an hour had fixed both those problems and resolved two more I hadn't planned to ask him about. Rather than just replace the extractor fan like-for-like he identified a much better model and changed the fitting so it could be accommodated. He was friendly, very knowledgeable and helpful. All for a very reasonable amount. I cannot recommend him highly enough.

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.
