Public evidence profile · Checked July 2026
How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.
These reviews are published independently on the named public source below, not testimonials this business chose to show. We bring them together and link each one back to where it appeared, so you can open the source and read it yourself.
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.

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.

Endorsement Reference
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.
Endorsement Reference
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.
Endorsement Reference
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.
