Electrical Installations in London
Rewires, consumer units, sockets and lighting
Our NICEIC approved electricians carry out electrical installation work in London, from a single new socket to a full rewire. We fit new consumer units, add sockets and lighting, and wire extensions, loft conversions and renovations to current wiring regulations. Every job is tested and certified when it’s finished, so you have the paperwork for building control, your insurer or a future sale. It’s part of our wider electrical services, and if your existing wiring needs checking first, we can carry out an EICR.

How your installation is carried out
- Survey and quote: We look at your existing wiring and consumer unit, talk through what you need and give you a free, fixed-price quote.
- Installation: Our electricians run cables, fit accessories and connect circuits with as little disruption as possible, protecting floors and furniture as we go and making good where agreed.
- Testing and certification: We test every circuit, show you how everything works and hand over the right certificate for the job.
When does a home need rewiring?
Rubber or fabric-covered cables, a fuse box with rewirable fuses, no RCD protection or too few sockets are all signs that your wiring may be out of date. Scorch marks, flickering lights and breakers that trip for no obvious reason are also worth checking.
If you’re not sure, get in touch. We’ll check your installation and tell you honestly whether you need a rewire or whether a repair will do.

What a fantastic company! From my first conversation with Sian to installation of my new Vaillant boiler they have been absolutely brilliant. Sian responded instantly via What's App when ever I had a question regarding pricing and installation. Sam the installer and his colleague with very friendly, professional, tidy and talked me through the full installation once completed. I have already given contact details to some of my work colleague's this morning. I will use them to service my boiler going forward in the future and for any other plumbing needs. Absolutely 1st Class Company!Posted on Google![]()

Easily one of the best experiences I’ve had with tradesmen. Sian was super friendly and helpful, and then Harry showed up early, fixed the issue promptly and was a legend! Highly recommended.Posted on Google![]()

I’ve been dealing with ongoing pump issues for as long as I can remember, and after multiple visits from different plumbers, nothing ever fully got resolved. Harry from Jennings was the first to actually diagnose the problem and sort it in one visit. Professional, efficient, and clearly knows his craft inside out. I couldn’t recommend Jennings more highly.Posted on Google![]()
