Electrical Repairs in London
Fault finding and repairs by NICEIC electricians
Our electricians carry out electrical repairs in London for homeowners, landlords and businesses. If a circuit keeps tripping, a socket has stopped working or your lights flicker, we track down the fault with proper test equipment and fix the cause, not just the symptom. We repair sockets, switches, light fittings, RCDs and breakers, and test the circuit before we leave. For power cuts or burning smells, call our emergency electrician, or see all our electrical services.

How we find and fix electrical faults
- Inspect: Tell us what’s happening and when. We check the consumer unit, look for signs of damage and find out which circuit is affected.
- Test and diagnose: We test insulation, earthing and RCD operation to pinpoint the fault, and unplug appliances one by one in case one of them is the cause.
- Repair and retest: Once you’ve agreed the price, we replace the faulty part or cable, then retest the circuit so you know it’s safe.
Why does my RCD keep tripping?
An RCD cuts the power in a split second when it detects current leaking to earth, which protects you from electric shock. If it trips again and again, it’s doing its job. The usual causes are a faulty appliance, water getting into an outdoor socket or light, or damaged cable.
Don’t keep resetting it and hoping for the best. Call us and we’ll find the cause. If your property has several faults, an EICR will give you a full picture of its condition.

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![]()
