Epsom's mix of Victorian terraces around the town centre, 1930s semis out towards Woodcote and newer builds near Epsom Common all throw up different electrical quirks. An old rewire job in a period property on East Street can mean dealing with lath and plaster and ancient cabling that's well past its best, while a newer house near Langley Vale might just need a consumer unit upgrade or extra sockets for a home office. Electricians working across Epsom and into Ewell, Stoneleigh and Ashtead tend to see a fair spread of both, which matters when you're choosing someone who actually knows the housing stock rather than just quoting off a standard job sheet.
The businesses featured here are drawn from public business listings and ranked mainly by review rating and how many reviews they've got, with a small lift given to those showing a working website and phone number. We read through each business's homepage to check that electrical work is genuinely their main trade, which stops general handymen or unrelated tradespeople sneaking onto a page like this. Listings flagged as permanently closed get removed automatically as part of that process. Where a business carries our Trust Verified badge, it means they've gone through a fuller check covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information (our How We Verify page sets out exactly what that involves). Businesses without that badge haven't been through that process with us, so it's worth doing your own homework before booking anyone.
Before you commit to an electrician, ask to see their qualification and registration details, whether that's NICEIC, NAPIT or another recognised scheme, and check they'll issue a proper certificate for the work, such as an Electrical Installation Certificate or a Minor Works Certificate. For anything involving a consumer unit change or rewire, ask how they handle Building Regulations notification, since this isn't optional. It's worth getting two or three quotes for bigger jobs like rewiring or an EICR, because prices can vary more than you'd expect between electricians covering the same postcode. And always ask what's included, some quotes cover making good after chasing out walls, others don't, and that gap can add up quickly.
How We Select & Rate The Best Electricians in Epsom
Businesses are ranked using review rating and review count from public business listings, with a small lift for those showing a working website and phone number. We check each business's homepage to confirm electrical work is what they primarily do, which keeps unrelated trades off the page. Listings marked permanently closed are removed automatically. Businesses carrying our Trust Verified badge have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for the full list. Other businesses shown here haven't been independently verified by us, so do your own checks before hiring anyone.
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 →

Is your business missing?

Simple jobs like fitting a new socket or light fitting typically run from around £60 to £120 including a call-out charge. A full consumer unit upgrade often costs between £250 and £450, while a rewire on a three-bedroom semi can range from £3,500 to £6,000 depending on access and how much making good is needed afterwards. An EICR (Electrical Installation Condition Report) for a typical Epsom house usually falls between £120 and £220. Prices vary depending on property size, age of the wiring and how easy the job is to access, so getting two or three quotes before you book is normal practice and worth doing.
Do I need an electrician for a fuse box or consumer unit change in Epsom?
Yes, this is notifiable work under Building Regulations and should be carried out by a registered electrician who can either self-certify the work or notify the local authority through their scheme. Trying to do this yourself, or using someone unregistered, can cause problems if you come to sell the property, since buyers' solicitors often ask for the paperwork.
How long does rewiring a house in Epsom take?
A full rewire on an average three-bedroom terrace or semi, common in areas like Rosebery Park or College Ward, usually takes between five and eight working days, plus extra time for plastering and decorating afterwards. Older properties with solid walls or awkward loft access can take longer, so ask your electrician for a realistic timeframe based on your specific house rather than a general estimate.
What certificate should I get after electrical work is done?
For most work you should receive either an Electrical Installation Certificate (for new circuits or significant changes) or a Minor Electrical Installation Works Certificate (for smaller jobs like adding a socket). Keep these safe, as they're often requested by mortgage lenders, insurers or buyers if you sell the property later.
Can an electrician in Epsom help with EV charger installation?
Many local electricians now fit home EV chargers, and costs typically range from £700 to £1,200 depending on your consumer unit, cable run length and whether groundworks are needed for the cable route. If you're on a driveway near an older property without off-street parking upgrades already done, ask for a site visit rather than a phone quote, since access and existing wiring make a real difference to the price.
How do I choose between different electricians in Epsom?
Check that any electrician you're considering is registered with a recognised scheme such as NICEIC or NAPIT and ask to see their registration number, which you can verify directly with that scheme. Look at recent customer reviews rather than just the overall rating, since patterns in comments about punctuality or tidiness tell you more than a star score alone. Ask for proof of public liability insurance and confirm whether quotes include materials, waste disposal and making good after the work. Finally, get a written quote rather than a verbal estimate, and be wary of anyone unwilling to put pricing and scope in writing.
