Barnet's housing stock is a real mixed bag, which keeps local electricians busy with all sorts. You've got Edwardian terraces around East Barnet, 1930s semis in Whetstone and New Barnet, and newer flat conversions near High Barnet and Totteridge, each with their own quirks. Older properties often still have outdated fuse boxes or ageing rubber and lead pipework hiding behind the walls, while newer builds bring their own issues with consumer unit spacing or EV charger installs where the driveway wasn't designed for one. Electricians working across the borough need to be comfortable switching between rewiring a period conversion one day and fitting smart home systems in a new-build the next.
The businesses featured here are pulled from public business listings and ranked mainly by review rating and review count, with a small boost given to those showing a working website and phone number. We also read through each business's homepage to check that electrical work is genuinely their main trade, which stops unrelated tradespeople from cluttering up the page. Any listing flagged as permanently closed gets removed automatically, so you're not wasting time on numbers that no longer connect. Where you spot a Trust Verified badge, that business has gone through our fuller verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company details. Have a look at our How We Verify page if you want the complete breakdown. For businesses without that badge, those checks haven't been done by us, so it's worth doing your own homework before booking anyone.
Before you commit to an electrician, ask to see their registration with a recognised scheme such as NICEIC or NAPIT, and get proof of public liability insurance too. Any notifiable work, like a full rewire or a new consumer unit, needs to comply with Part P of the Building Regulations, so ask how they'll certify the job and whether you'll receive an Electrical Installation Certificate afterwards. It's also worth checking how long they've been trading locally and asking for a couple of recent customer references if you're having major work done. Getting two or three quotes is standard practice in Barnet, since prices can vary quite a bit between firms, and it gives you a decent feel for who actually listens to what you need rather than just quoting a number and moving on.
How We Select & Rate The Best Electricians in Barnet
Rankings are based on review rating and review count taken from public business listings, with a small lift given to businesses that show a working website and phone number. We check each business's homepage to confirm electrical work is what they primarily do, and listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have gone through our full verification process, 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 detail. Other businesses on this page haven't been independently verified by us, and being listed isn't an endorsement. Always carry out your own checks before hiring anyone.

Small jobs like fitting a new socket or light fitting typically run from £60 to £120, including call-out. A full consumer unit upgrade tends to sit between £250 and £450 depending on the property and how much extra work is needed to bring wiring up to standard. A full rewire on a three-bedroom terrace in Barnet can range from £3,500 to £6,500, depending on access and whether floors or walls need lifting. Prices shift depending on the age of the property and how easy the wiring is to get at, so getting two or three quotes before you commit is a sensible move.
Do I need a certificate after electrical work in Barnet?
Yes, for most notifiable work such as a new consumer unit, rewiring, or adding circuits in a kitchen or bathroom. Under Part P of the Building Regulations, this work needs to be certified, either through a registered competent person scheme like NICEIC or NAPIT, or by getting Building Control sign-off separately. Ask your electrician upfront how they'll handle certification and get the paperwork in writing before the job starts.
How long does a full rewire take?
For a typical three-bedroom house in areas like Friern Barnet or Cockfosters, expect anywhere from five to ten working days, longer if floorboards and plaster need to be lifted and made good afterwards. Flats and smaller properties can sometimes be done in three or four days. It's disruptive, so ask your electrician to walk you through the stages and how they'll manage things like temporary power while sockets are out of action.
What should I check before hiring an electrician for emergency work?
Confirm they can actually get to you quickly, some firms advertise 24-hour callout but really mean next working day. Ask for an estimate over the phone based on the fault you're describing, and check whether there's a separate call-out charge on top of labour. For anything involving a tripped consumer unit or exposed wiring, don't attempt a fix yourself, isolate the circuit at the fuse box if it's safe to do so and wait for a qualified electrician.
Can an electrician help with an EV charger install in Barnet?
Most local electricians now offer EV charger installation, and costs typically range from £800 to £1,200 depending on the charger model and how far the cable run is from your consumer unit. Properties without off-street parking, common in parts of New Barnet and East Finchley border streets, may need a chat with the installer about cable routing options before work starts. Always confirm the charger itself comes with manufacturer warranty separate from the installation guarantee.
How do I choose between electricians in Barnet?
Start by checking their registration number with NICEIC, NAPIT or a similar scheme directly on that scheme's website, rather than just taking their word for it. Ask to see proof of public liability insurance and check it's current, not expired. Read through recent customer reviews for patterns, one bad review isn't a red flag but several mentioning the same issue is. Get quotes from at least two or three electricians for anything beyond a small repair, and ask each one exactly what's included, since some quotes cover materials and certification while others don't.
