Electrician in London You Can Rely On
If you’re searching for an electrician in London who turns up when they say they will, quotes fairly, and does the job properly the first time, that’s exactly what First Strike Electrical Ltd has been doing since 1999. We’re an NICEIC approved electrical contractor based in Marylebone, in the City of Westminster, and we work right across London on everything from a single faulty socket to a full commercial rewire.
Electrical work isn’t somewhere to cut corners. A poor installation can mean nuisance trips today and a genuine fire risk tomorrow, so whether you’re a homeowner in Fitzrovia, a landlord in Bayswater, or a facilities manager running a building in the City, you want an electrician London residents and businesses have actually vetted, not just the first name that comes up in a search. That’s the gap we set out to fill over twenty five years ago, and it’s still what gets us out of bed for a 3am emergency call today.
Why Londoners Choose First Strike Electrical
NICEIC approved, so the paperwork is right as well as the wiring. Being NICEIC approved means our work is periodically assessed against British Standard BS 7671 (the IET Wiring Regulations), and that notifiable domestic work is certified and registered correctly. If you’ve ever tried to sell a house or satisfy a mortgage lender with missing electrical certificates, you’ll know why this matters. It’s not a badge we bought, it’s a standard we’re checked against.
Trading in London since 1999. We’ve wired houses that have since been extended twice, fitted consumer units that are still going strong, and watched entire streets go from gas lighting relics to smart homes. That length of time in one city means we’ve generally already seen your specific problem before, whether it’s the quirks of Victorian lath and plaster wiring in a period conversion or the demands of a modern glass office fit-out.
Available around the clock. Electrical faults don’t check a diary before they happen. Our emergency electrician London service runs 24 hours a day, 7 days a week, because a dead consumer unit at midnight on a Sunday is exactly as urgent as one at 9am on a Tuesday.
Fair, transparent pricing. We’ll tell you what a job involves and roughly what it costs before we start, not after. No jargon, no pressure to buy work you don’t need, no surprise invoice at the end.
Genuinely local. We’re based in W1, not routing your call through a national call centre to a subcontractor you’ve never met. When you call us, you’re talking to the people who’ll actually be doing the work, or someone who works alongside them every day.
Electrical Services We Offer in London
We split our work into four areas, each with its own dedicated page so you can see exactly what’s involved and what to expect.
Common Electrical Issues We’re Called Out to Fix in London
London’s housing stock is a mix of Victorian and Edwardian conversions, post-war rebuilds, and new-build flats, and each brings its own electrical quirks. A few of the jobs we see most often:
Outdated fuse boards.
Many older London properties still have wire fuse boards or early plastic consumer units with no RCD protection. These aren’t necessarily dangerous by themselves, but they don’t offer the same protection against electric shock as a modern board, and insurers and mortgage surveyors increasingly flag them.
Flickering lights and nuisance tripping.
Sometimes it’s a loose connection, sometimes it’s an overloaded circuit, and sometimes it’s a sign a consumer unit is at the end of its working life. Either way, it’s worth having checked rather than resetting the trip and hoping it doesn’t happen again.
Rising demand for EV chargers and higher loads.
As more London households run an electric car, an EV charger, or high-draw appliances off a supply that was designed decades ago, we’re seeing more consumer units and incoming supplies that need upgrading to cope safely.
Period property rewires.
Converting a Victorian terrace into a modern home usually means stripping out old wiring entirely rather than patching it, particularly if lath and plaster walls or old lead-sheathed cable are involved.
Burning smells or visibly damaged sockets and switches.
This is one to treat seriously. If you notice this, switch off the circuit at the consumer unit if it’s safe to do so, and call us straight away.
Signs It’s Time to Call an Electrician, Not Reach for a YouTube Tutorial
Minor jobs like changing a light bulb are obviously fine to do yourself. Anything involving the fixed wiring, a consumer unit, or work that would be notifiable under Part P of the Building Regulations is a different matter, both legally and for your own safety.
As a general rule, if a job involves opening up a consumer unit, adding a new circuit, working in a bathroom or kitchen, or you’re not entirely sure what you’re looking at, it’s worth a phone call before a screwdriver. Getting it wrong isn’t just a wasted afternoon, it can invalidate your home insurance and put your household at real risk.
Fully Certified, Fully Accountable Work
Because we’re NICEIC approved, our certification isn’t just a piece of paper we hand you. It’s backed by a scheme that assesses our technical work against national standards. For notifiable domestic electrical work under Part P of the Building Regulations, that means the right paperwork goes to the right places, protecting you if you ever need to prove the work was done properly, whether that’s for a home insurance claim, a house sale, or a landlord’s legal obligations.
We’re also happy to talk through, in plain English, exactly what any certificate we issue actually covers. Too many people are handed paperwork they don’t understand. We’d rather you understood what you were paying for.
Areas We Cover Across London
We’re based on Crawford Street in Marylebone, which puts us within easy reach of central London, including Fitzrovia, Mayfair, Paddington, Bayswater and the wider City of Westminster, and we regularly travel further out across Greater London for both domestic and commercial jobs. Being based just off the Marylebone Road means we can generally get a van across central London quickly, which matters when a job is genuinely urgent.
If you’re not sure whether your address falls within our working area, the simplest thing is to give us a call. We’d rather tell you honestly if a job is outside our usual patch than take it on and let you down. We’re also happy to discuss larger commercial or multi-site jobs further afield in Greater London, where a single point of contact for electrical work across several properties can save a facilities team a lot of admin.
Our Process, Start to Finish
- 01
Get in touch.
Call, email, or send a message describing what’s going on. For anything urgent, phone is always fastest.
- 02
Assessment and quote.
For non-emergency work, we’ll ask enough questions (or arrange a site visit) to understand the job properly before giving you a price, so there are no surprises later.
- 03
The work itself.
Our electricians turn up when they say they will, protect your floors and furniture while they work, and clean up after themselves. You’ll always know what’s being done and why.
- 04
Testing, certification and sign-off.
Every job is tested before we call it finished. Where certification is required, whether that’s a minor works certificate, an electrical installation certificate, or an EICR, you’ll receive the correct paperwork, which matters for insurance, resale, and Building Control purposes alike.
What Our Customers Say
Over more than two decades of trading in London, we’ve built a reputation the way every trade business should: job by job, referral by referral.
Rather than ask you to take our word for it, we’d encourage you to check our latest Google reviews before you book, and to ask us directly for references from recent domestic or commercial jobs similar to yours.
Frequently Asked Questions
Is First Strike Electrical actually NICEIC approved?
Yes. We’re assessed under the NICEIC scheme, which checks our technical competence and business practices against national wiring standards. You’re welcome to ask us for our registration details before booking.
Do you offer a genuine 24 hour emergency electrician service in London?
Yes, our emergency line runs around the clock, every day of the year, for faults that can’t reasonably wait, such as total loss of power, a tripping consumer unit, or exposed live wiring. See our emergency electrician London page for more detail on what counts as an emergency and what to do while you wait for us.
How much does it cost to hire an electrician in London?
It depends entirely on the job. A socket replacement and a full rewire are obviously priced very differently, and location, access, and the age of a property’s wiring all play a part too. We give clear, upfront pricing before starting non-emergency work, so you’re never guessing.
Do you work on homes and businesses, or just one or the other?
Both. Our team handles domestic electrical work such as rewiring and consumer unit upgrades, and commercial work such as office and retail fit-outs, fire alarm testing, and planned maintenance. See our domestic and commercial pages for the specifics.
Which parts of London do you cover?
We’re based in Marylebone in the City of Westminster and regularly work across central London and further into Greater London. If you’re unsure whether we cover your area, just call and ask, it takes thirty seconds and saves any confusion later.
Do I need an electrician who’s NICEIC approved, or is any qualified electrician fine?
You don’t legally have to use an NICEIC approved contractor for most electrical work, but using one gives you a level of independent checking that an unregistered electrician doesn’t have, and it can matter for certification, insurance, and mortgage or sale purposes on notifiable work.
Can you provide certification for a house sale or mortgage application?
Yes. Where work we carry out is notifiable under Part P, or where you specifically need an EICR for a sale, purchase or remortgage, we issue the correct certification and can explain exactly what it covers before you pass it on to your solicitor or lender.
Do you offer ongoing maintenance for landlords or businesses with multiple properties?
We can arrange rolling electrical testing and minor repair work across several properties or sites, rather than you needing to call a different electrician for every address. Get in touch to discuss how that would work for your portfolio or premises.
