Out initial enquiry met with an immediate response, followed very quickly by a full electrical survey, Quotation for the necessary work, and an appointment for the work to be carried out. Having recently had the house re-decorated, we were concerned about possible disruption and repeated expense, but the work was done very tidily with no damage at all. Throughout, what was needed and what was being done were explained to us. The firm's representation were friendly and courteous.

They had a small job at my place. They arrived at 8 am and then at 10:30 am they left for 1-hour lunch break when the job was around 3hrs! The most unprofessional and unethical company and staff I have ever seen!

Contacted this Company at 10am. They responded by telephone to acknowledge and called to my home within 60 minutes. Very professional in every way, a new fan was obtained promptly and fully fitted and operational within an hour. A double gang switch was also fitted to separate the light operation from the fan. I highly recommend them. This Company does regular contractual work to our block of flats and have never let us down. On a personal level, I shall use them again.

Having moved to this area recently, I had to find a good electrician and being a member of Which, I naturally checked out their Electrician reviews. I contacted J B Electrical Contractors Limited and a couple of days later, Nail came to change a few single sockets and replaced them with Double Sockets containing USB function I mentioned that the CCTV which I had installed recently by another company did not capture everywhere I'd wanted. Nail looked at it, asked what I wanted to be able to see, made a few adjustments and now I am able to keep an eye on my cockapoo, no matter where she is in the garden. It's an added bonus that they have expertise in lot of areas which I am likely to need help with....no need for me to search around for a good company as I will call on them in future.

This time it was an extension in Teddington-garage and orangery. I?m using JB Electrical few times a year for last 6 years, since I have star my own company. But I know them for 15 years, as the company I have worked before for 9 years, used them all the time. They always do excellent work.

I had the house rewired and a new fuse board installed, as well as several new sockets installed and changes to some ceiling lights made. The work was carried out very well and at completion, everything was left clean and the way it was before. I am completely satisfied with their work and can highly recommend J B Electrical Contractors Ltd.

My wife and I are of very advanced years and returned home from a few hours away from the house to find that apart from lighting there was no electric power to any other appliances. Enquiries of the local electricity company showed this only applied to our house. Within about 45 minutes of my phone call to JB Electrical a young and extremely pleasant electrician called upon us and successfully set about restoring electric power to all our appliances. When he had finished he wrote us out simple instructions about what to do first should a similar problem reoccur. We were so impressed with the prompt and excellent attention. David

I had the whole house rewired, a new fuse board, ceiling fans and additional sockets installed as well as external sockets, lights and a camera. The team were polite and friendly and worked very hard, were very efficient and went out of their way to avoid any disruption, especially that I had limited mobility. I was extremely impressed with all the work. The repositioning of the sockets and a lot of the other work have really made a difference to the quality of my life. Everything is more accessible and they put everything back properly and made no mess. I cannot praise them enough! The work was professional and properly done, and was worth every penny.

JB reacted quickly to my call and sent a quick, polite and professional operative. Tested an oven which was not working and established it was beyond repair. Also restored outside lights after speedily going to purchase needed parts.

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.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
