Why Londoners call us first in an emergency

We move fast

Most emergency calls get a qualified electrician on-site within the hour, anywhere across Greater London. You speak to a real person, not an answering service.

Safe and certified

Every electrician is NICEIC registered and works to BS 7671. We isolate the danger first, find the root cause, and put it right, not just paper over the symptom.

No nasty surprises

We confirm the call-out charge before we set off, then agree the cost of any repair with you before we start. Clear, honest pricing even at 2am.

Power went out at 11pm on a Sunday. Called Capital Electrician and someone was at my door within 45 minutes. Turned out to be a faulty connection in the consumer unit. Fixed on the spot. Could not ask for more.

Needed an EICR for my rental flat before the new tenants moved in. Booked for the following week, electrician arrived on time, and I had the certificate emailed to me the same day. Simple and professional.

Wandsworth

January 2026

Had our 1930s house fully rewired. It was a big job and they were upfront about the disruption, but the team worked tidily and finished a day ahead of schedule. The new consumer unit is a big improvement on the old fuse box.

Harrow

Our old fuse board kept tripping. Had a new consumer unit with RCBOs installed. No more losing power to the whole house when one circuit plays up. Fair price and clean work.

Installed downlights throughout our kitchen extension and outdoor lights in the garden. Really pleased with the result. The electrician helped us choose the right colour temperature and spacing.

Had an Easee charger fitted at home. The survey was thorough and they explained I would need a small upgrade to my consumer unit, which was included in the quote. No surprises. Charging my car at home now, which is so much more convenient.

Manage a small office building and use Capital Electrician for annual emergency lighting tests and PAT testing. They are always easy to deal with and work around our office hours. Records are well organised.

Rachel P.

Richmond

Had a socket that kept sparking when I plugged things in. They came out the next morning, found a loose connection, replaced the socket, and checked the rest of the circuit. Quick and reassuring.

I have four rental properties and use these guys for all my EICRs and remedial work. They coordinate with my letting agent so I barely need to get involved. Always compliant, always on time.

Linda F.

Fulham

March 2026

Needed extra sockets in our home office and USB sockets fitted in the kitchen. Small job but they treated it with the same professionalism as a big one. Tidy work, fair price.

Daniel S.

Hackney

November 2025

Our RCD kept tripping and nobody could figure out why. Capital Electrician found a damaged cable behind the kitchen units that was only faulting when the dishwasher heated up. Proper diagnosis, not guesswork. Very impressed.

Karen B.

Croydon

January 2026

Had a consumer unit upgrade and EICR done together. The electrician explained everything clearly and the certificates arrived by email that evening. Good experience overall, would use again.
