London's housing stock throws up challenges that electricians elsewhere rarely encounter. Victorian terraces across Hackney, Islington, and Battersea often still have original wiring runs buried in lath-and-plaster walls, and older properties throughout zones two and three regularly turn up deteriorating rubber-insulated cables that need full rewires rather than quick fixes. Newer builds in Nine Elms, Stratford, and Wembley Park bring their own headaches, with shared riser cupboards, communal metering arrangements, and building management systems that need co-ordination before any domestic work can start. Add in the sheer density of the city and the fact that many Londoners live in converted flats where circuits are shared across multiple dwellings, and it's clear that finding an electrician who actually knows the local building types makes a real difference. Expect to pay roughly £50 to £80 per hour for a qualified electrician in inner London, with consumer unit replacements typically running £400 to £700 and a full rewire of a three-bedroom Victorian terrace often coming in between £3,500 and £6,000 depending on access and the state of the existing installation.

The businesses listed on this page are drawn from third-party public business listings and ranked primarily by public review rating and review count, with a small additional lift for those that have a working website and a contactable phone number. Before any business appears here, we check its homepage to confirm that electrical work is what it primarily offers, which is how unrelated trades or general handymen get filtered out. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge next to a business, that company has gone further and passed our full independent verification process, which covers trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. You can see the complete list of what that involves on our How We Verify page. Businesses that don't carry that badge have not been independently verified by us, and it's worth keeping that in mind when you're comparing your options.

Before you book any electrician, ask to see their NICEIC, NAPIT, or ELECSA registration, all of which confirm they're a competent person able to self-certify notifiable electrical work and issue an Electrical Installation Certificate without the need for a separate building control sign-off. For larger jobs like a full rewire or a new consumer unit, always get at least three written quotes and make sure each one specifies the same scope of work, because vague quotes make meaningful price comparisons impossible. Check that whoever you hire holds adequate public liability insurance before they start, and once the job is done, make sure you receive an Electrical Installation Certificate or, for a periodic inspection, an Electrical Installation Condition Report. These documents matter if you sell the property or make an insurance claim further down the line.
How We Select & Rate The Best Electricians in London

Rankings on this page are driven by public review rating and review count pulled from third-party business listings, with a small lift applied to businesses that have a working website and phone number. We check each business's homepage to confirm electrical work is what they primarily offer, keeping unrelated trades off the page. Permanently-closed listings are removed automatically. Businesses displaying a Trust Verified badge have additionally passed our full verification, covering qualifications, accreditations, public liability insurance, trading history, customer review history, and registered company information. See our How We Verify page for the complete list. All other businesses on this page have not been independently verified by us, and inclusion is not an endorsement. Always carry out your own checks before hiring.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does an electrician cost in London?
Hourly rates typically range from £40-80, with experienced contractors charging £60-80 per hour. Call-out fees add £30-60. Simple jobs like socket installation cost £80-150, whilst consumer unit replacements run £300-800. Full house rewires vary dramatically: £3,000-6,000 for a two-bed terrace, £8,000-15,000 for larger properties. Location affects pricing, with central London commanding premium rates. Always get two or three written quotes for comparison.
Do I need Part P certification for electrical work in London?
Part P applies to notifiable electrical work including new circuits, bathroom electrics, and consumer unit changes. Your electrician must be registered with an approved scheme like NICEIC, NAPIT, or STROMA to self-certify this work. Without proper certification, you'll need separate building control approval, adding cost and complexity. Always check your contractor's registration before starting notifiable work.
How long does rewiring a London house take?
A typical two-bedroom terrace takes 3-5 days with minimal disruption methods, whilst full strip-out rewires need 5-8 days. Three-bedroom houses require 5-10 days depending on access and complexity. Victorian properties with solid walls take longer than modern builds. Partial rewires for kitchen or bathroom renovations usually complete within 1-3 days. Factor in extra time for plastering repairs and redecorating afterwards.
Can electricians work on listed buildings in London?
Yes, but they'll need conservation area or listed building consent for visible external changes like new cable routes or meter positions. Internal rewiring rarely needs permission if it doesn't affect historic fabric. Experienced contractors understand requirements for concealed wiring in period properties. Check with your local council's conservation officer for complex projects involving structural alterations or external modifications.
What electrical problems are common in London properties?
Older properties often have outdated fuse boxes needing consumer unit upgrades. Victorian houses frequently lack sufficient sockets for modern needs. Shared freehold buildings may have complex supply arrangements requiring specialist knowledge. Basement conversions need proper earthing systems. Smart home installations require neutral wires that older properties sometimes lack. Rising damp can affect ground floor electrics in period buildings.
How do I verify an electrician's credentials and reliability?
Check their NICEIC, NAPIT, or STROMA registration online using their membership number. Verify public liability insurance (minimum £2 million cover). Request three recent references and actually contact them. Check Companies House for trading history and financial health. Look for consistent positive Google reviews over time. Ask to see their qualification certificates and ensure they're qualified for your specific work type.
