How to start an electrical business in 10 steps (UK guide)

Going self-employed is the moment a lot of electricians start doing the sums. You know what the firm charges for a consumer unit change. You know what you get paid for fitting it. The gap looks very tempting.

It can be. But an electrical business has more hoops than most trades, and one or two of them catch newly qualified sparks out. This guide covers how to start an electrical business in 10 steps, how hard it really is and what it costs, with the regulations checked against the official sources as of October 2026.

Quick disclaimer: I'm not an electrician. I build websites and do SEO for trades. So I've stuck to what the IET, the government and the schemes themselves say, linked it all, and saved my own opinions for the marketing end.

How hard is it to start an electrical business?

Harder than most trades, for one main reason. In England you can't sign off notifiable domestic electrical work yourself unless you're registered with a competent person scheme, and the schemes have entry requirements of their own.

The one to check first: NICEIC's Domestic Installer scheme asks for a Qualified Supervisor with at least two years' responsibility for electrical work (NICEIC). If you only qualified last year, find out where you stand before you hand your notice in. Other schemes set their own criteria, so compare a few.

The rest is the same graft as any trade: finding work, pricing it properly and keeping on top of the paperwork. And there's steady demand if you want it. Landlords in England must have their electrics inspected and tested at least every five years, and since 2025 that's applied to social housing as well as private rentals (gov.uk). That's a lot of EICRs every year.

How to start an electrical business in 10 steps

1. Make sure you're fully qualified and up to date

   The industry benchmark for a fully qualified electrician is a Level 3 competence-based qualification (usually an NVQ, often through an apprenticeship) plus a pass in the AM2 practical assessment. That's what the JIB looks for, alongside the current wiring regulations qualification and the health and safety test, before it issues an ECS Gold Card. Apprentices sit the AM2S, and experienced workers coming through the experienced worker route sit the AM2E.

   You also need to be current on the wiring regulations. As of October 2026 that's BS 7671:2018+A4:2026, and the IET says the previous version stays valid only until 15 October 2026 (IET). Check what your scheme expects you to hold.

2. Decide what kind of electrical work you want

   Domestic rewires and consumer units, landlord EICRs, commercial fit-outs, EV chargers, solar and batteries: they're different businesses with different customers, kit and registrations. You don't have to choose forever, but your first year goes better if you know which phone calls you want, and it decides which scheme and insurance you need. If EV chargers appeal, I've written about winning EV charger and rewire searches.

3. Join a competent person scheme

   In England, some domestic electrical work is notifiable under Part P of the Building Regulations: a new consumer unit, a new circuit, and changes to circuits in the spaces around baths and showers (Planning Portal). Register with a competent person scheme and you can self-certify that work. If you're not registered, it has to go through building control (or, in England, a third-party certification scheme), which is slower and dearer for the customer. Wales has a slightly different list, and Scotland and Northern Ireland run their own systems.

   The government's list of authorised schemes for electrical work in homes includes Certsure (which runs NICEIC and ELECSA), NAPIT, BESCA and Blue Flame Certification, among others (gov.uk). For a feel for cost, NICEIC lists its Domestic Installer scheme for 2026/27 at a £95 application fee plus £600 for the first year, both before VAT, with an assessment of about three hours. Compare at least two schemes on price, assessment and support.

4. Choose sole trader or limited company

   Most sparks start as sole traders. You register for Self Assessment once you earn over £1,000 in a tax year, by 5 October after the end of the tax year you started (gov.uk). A limited company costs £100 to register online with Companies House, and directors now verify their identity through GOV.UK One Login. It's more admin, but it separates you from the business and can be more tax-efficient as profits grow. Whether that's true for you is a conversation for an accountant.

   Two more tax points. Making Tax Digital for Income Tax has applied since April 2026 to sole traders with qualifying income (turnover, not profit) over £50,000, dropping to £30,000 in April 2027 and £20,000 in April 2028 (HMRC). And if you work for building contractors you'll come under the Construction Industry Scheme, where they deduct 20% from your payments if you're registered and 30% if you're not. So register.

5. Get your insurance sorted

   The covers most electrical businesses look at:

   • Public liability. Not a legal requirement, but customers and contractors expect it, and plenty won't let you start without seeing the certificate. Commercial clients often set a minimum level of cover, so ask before you buy.
   • Employers' liability. A legal requirement the moment you employ someone, apprentices included: at least £5 million of cover, and you can be fined £2,500 for every day you're not properly insured (gov.uk).
   • Professional indemnity. Worth asking your broker about if you'll design installations or produce inspection reports that people make decisions on.
   • Tools and test kit. Your tester is expensive and small enough to walk off. Check what the policy says about vans left overnight.
   • Van insurance with business use. Commuting cover won't do.

6. Buy the right test kit

   Your multifunction tester is the one tool you can't fudge. A decent one runs from several hundred pounds to well over £1,000 new, and you'll need to keep it calibrated with records to show your scheme. Add a voltage indicator and proving unit, then buy the rest of your tools as the jobs demand them rather than all on day one.

7. Get a van that looks like a business

   A tidy used van with racking beats a new one on finance in year one. Keep it clean and get it lettered with your name, number and web address. To a homeowner deciding whether to let you near their fuse board, your van is your shop front.

8. Set up your paperwork

   Certificates are part of the job: Electrical Installation Certificates, Minor Works certificates and EICRs, and there's plenty of software and apps to produce them. Alongside that you need a quote template, terms and conditions, and invoicing that works with Making Tax Digital. If you agree jobs in customers' homes, your paperwork also has to tell them about their 14-day right to cancel under the Consumer Contracts Regulations. Miss it out and the window can stretch to 12 months.

9. Work out your prices

   Start with what the business needs to earn, not what the sparky down the road charges. Made-up numbers to show the method: you want £45,000 a year before tax, your running costs (van, scheme fees, insurance, calibration, software, phone, accountant) are £10,000, and you manage about 190 paid days once you take off holidays, quoting, admin and quiet weeks. £55,000 divided by 190 is about £290 a day before materials. That's your floor, not your price.

   For the common jobs, like consumer unit changes, EICRs and extra sockets, think about fixed or "from" prices. Customers like knowing roughly what they'll pay, and it stops you spending your evenings quoting for £80 jobs.

10. Get your first customers

    This is the bit I know, so it gets its own section below.

How much does it cost to start an electrical business?

Less than you might think if you already own your tools. Here's how it breaks down, with the fixed fees as listed by the organisations themselves as of October 2026:

So a spark who already has a van and tools can realistically get going for the cost of a scheme, insurance and a good tester. The bigger cost is the quiet weeks at the start before word of mouth kicks in, so have a couple of months' bills put aside if you possibly can.

Getting your first customers as an electrician

I've spent over ten years in SEO and grown my own websites from 10 clicks a day to 1,000. None of it involved tricks. It was getting the basics right before anything clever, and it's the same for a new electrical business.

A name people remember

Three initials and "Electrical Services" tells nobody anything, and there are probably a dozen of them. Pick a name that works on the van, over the phone and as a web address. My guide to trade business name ideas has the checks to run first.

A Google Business Profile

When someone's lights trip at 7pm they search "electrician near me" and ring one of the three businesses on the map. That free listing is your Google Business Profile, and here's how to set up a Google Business Profile properly as a trade that goes to customers. Add your scheme membership in the description and photos of tidy work, because a neat consumer unit photo sells better than any slogan.

A website that proves you're registered

Electrical work makes people nervous, and they want proof before they let you in. A simple site that shows your scheme registration, your services, the areas you cover and real photos does that job. Not sure you need one yet? Read do I need a website first. If you do, this is how I build websites for electricians.

Reviews, steadily

Ask every customer for a Google review before you leave, and text them the link. A few a month beats fifty in one go. Landlords and letting agents who like your EICRs will often send repeat work too, so look after them.

SEO once you're established

Ranking for "electrician in Barnsley" or "EV charger installer Sheffield" is a longer game, and I'd only pay for it once your profile, website and reviews are in place. When that time comes, here's how I approach SEO for electricians.

Mistakes that quietly cost new electricians work

I look at a lot of trade websites and Google profiles. These are the ones I'd fix first, and none of them cost money:

• Hiding the registration. If you're with a scheme, say so near the top of your website and on your Google profile, with your registration number. Customers look for it, and some check it on the scheme's own search.
• The wrong main category. On your Google profile, "Electrician" is the obvious main category for most domestic sparks. Pick something vaguer and you can end up matched to the wrong searches.
• Stock photos. A photo of a model in a hard hat holding a screwdriver the wrong way round convinces nobody. Your own phone photos of real boards and tidy cable runs beat it every time.
• Listing every town in the county. Google still weighs distance. Be honest about where you actually work and you'll show up better in those places.
• Not answering the phone. The first spark to pick up often gets the job. If you're up a ladder all day, a missed-call text back is better than silence.

Questions about starting an electrical business

Can you start an electrical business without being an electrician?

You can own one, but the notifiable work has to be done or supervised by qualified people, and schemes assess the business's Qualified Supervisor, not just the owner. In practice that means employing an experienced electrician who meets the scheme's requirements before you take on domestic work.

Do I have to join NICEIC?

No. NICEIC is one of several authorised competent person schemes, and you can also use building control for notifiable work. Plenty of domestic electricians join one anyway, because self-certifying is quicker and customers recognise the logos.

How long does it take to set up?

Registering the business can take a day. The scheme is usually the slow part, because you need to show examples of your work and book the assessment, so start that process early.

Do I need to register for VAT?

Only once your taxable turnover goes over £90,000 in a rolling 12 months, as of October 2026 (gov.uk). Most domestic customers can't reclaim VAT, so registering early makes you dearer to them. Talk it through with an accountant.

Where I come in

I can't test an RCD, but I can make sure people looking for an electrician in your area find you and trust you enough to ring. I build trade websites personally: £497 one-off, no VAT, no deposit, and you see your homepage design within 24 hours of the set-up call before you pay anything. Hosting and your web address are £20 a month, paid by you.
