Quality workmanship. Trustworthy and communicative.

Jon was recommended to us by company doing our garden update. He gave us good ideas for our garden lighting and power, including inside our shed - ideas better than ours, as we'd been struggling to picture the best solution. He dovetailed really well with the gardeners, ensuring underground cabling was laid at the right time, then returned after gardeners had finished to complete the installation. We now have power and spotlights for our water feature and light on our shed, all controlled from the house, plus power and light in our shed. We are delighted with the work. He was conscientious with the high quality of his work and the parts he privided. On top of that Jon kept us informed of when he would be visiting us and ensured all cabling that could be seen was tidily clipped to our wall, plus he cleared up all the rubbish bits at the end. I would use Jon again and highly recommend his services.

Electrical work: extra sockets outside and upstairs, a light over the kitchen sink.

This firm did some work for a friend in N13 issuing a condition report as my friend lets the house out and so I asked them to work at my house in N22. The work was done swiftly and efficiently at the quoted price, both for my friend and at our house, where two extra sockets were put in, one outside, one in a bedroom. We also had a light fitted above the kitchen sink. They tidied away afterwards and I would recommend this firm to friends and family.

Sockets & RCD

Very happy to have JMB back for some necessary repeat business. Nice guys. Quick. Reliable. Tidy workers and who take care of their work. Could not ask for more. We had an electrical issue that Jon gave us the benefit of his knowledge and allowed us to agree on expectations before starting the work. We really appreciate Jon's customer care and sincerity. As a result, we agreed on the work scope upfront rather than anything being left to chance. We are very pleased to have found JMB and will use them again.

Our go to electrician

Jon has been our go to electrician for the last few years. He has converted 70+ spotlights to LEDs, installed smoke alarms, upgraded our fuse box and installed new lights. He is quick to respond, reliable, tidy, and knowledgeable. Jon understands customer requirements to be able to adapt solutions to fit. During the last job he was very flexible highlighting a better solution to the one we had planned which worked out quite a bit cheaper. If you need an electrician, I’d recommend Jon.

Lighting installation

Jon has recently replaced faulty lighting and installed recessed lighting in my Daughter's bedroom. In fact he managed to fix the problem with the existing lighting on an earlier visit which he didn't charge me for. However it needed upgrading and as always Jon was my first choice contractor. His work is always competitively priced, he is timely, polite, but most of all you know you are going to get a very high standard of work which he won't leave until he's totally happy with it. This includes making sure he cleans up every bit of mess that has been made along the way. I probably trust Jon more than any other trader I use and would highly recommend him for any electrical work. He also didn't have to ask me to write this review, I offered.

Lighting work

JMB Electrical Service replaced our old lights and brought us into 21st Century with new LED lights. We had been putting off the work for some time and are so glad to have found JMB. Their service is fantastic, they are really nice guys, the work was done professionally, on time with the minimum of disruption. They were such tidy workers, it was a pleasure having them round to do the work. We've liked the work and lights so much we still haven't stopped walking around the house looking up at the ceiling with big grins on our faces. Great job. Many thanks.

Excellent Customer Service

JMB Electrical Services is efficient: I was extremely happy with the timeframe between an acknowlegement and completion of an initial, smaller job. A fuller quote is due but that was made clear from the offset when I supplied my complete list of tasks. Knowledgeable, responsive and friendly. I highly recommend JMB.

A truly trusted trader

I have used Jon twice in the last couple of months, and I have found him totally reliable and professional. I will certainly use him again. He is polite, on time, cleans up after him and does not try to con you, a welcome change from some traders out there.

Reliable and excellent electrician

I have used Jon for numerous jobs over the past few years and wouldn't think of going to anyone else now. His work is outstanding but what is particularly important to me is he is totally reliable. Nothing is too much trouble. He always turns up when he says he will and if he can't he will let you know. Reasonable price and value for money.

Great Service

Jon was fantastic throughout. I had just moved into a new property whilst expecting my first child. I needed various work done in the house at a short notice. Jon was understanding and was able to review the work quickly and was able to complete it all the next week. We had light fittings changed, new sockets installed and others fixed. As well as changing the fuse box. Great communication throughout and was flexible when needed to be. Thanks for the great work.

Jon is a self employed electrician who did some electrical alterations on our house and then a full electrical test on the whole house, for which he issued a 5 year certificate. He gave very good personal service and explained things well. Thoroughly recommend his services.

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Verify at the sourceCheck them yourself

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 register
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.
