How to Start an Electrical Business in the UK

Is Starting an Electrical Business Right for You?

Electrical work is one of the trades where going self-employed makes most sense. Demand arrives from several directions: tripping circuits that cannot wait, consumer unit upgrades and rewires on older housing, landlords who need condition reports before a tenancy, and newer work in EV chargers, solar and batteries. Customers choose on registration, reviews and responsiveness rather than price alone, which suits a local business that answers its phone. Most are started by people with years on the tools for a contractor who sense they generate more than they are paid.

Working for yourself changes the job. You become the person who quotes, orders materials, keeps the instruments calibrated, writes the certificates, notifies the work, chases invoices and does the books after a day in a loft. The early months are uneven: small jobs that barely cover the fuel, then a rewire that ties up three weeks and pays six weeks later. The people who do well are methodical about paperwork and willing to turn away work outside their competence or registration.

If you are qualified and experienced, the business side is learnable. If you are new to the trade, the usual route is an apprenticeship, or Level 2 and Level 3 electrotechnical qualifications with the practical assessment and supervised site experience that follow, then time with an established contractor before setting up alone. Short courses promising a fast route exist, but assessors, insurers and landlords judge experience, and electrical work done badly has serious consequences.

Qualifications, Registrations and Rules

• Qualifications and the Wiring Regulations. No licence is needed to trade as an electrician, but the recognised standard is a Level 3 electrotechnical qualification, usually gained through an apprenticeship or a diploma followed by the NVQ and a practical assessment, plus a current qualification in BS 7671, the IET Wiring Regulations, which is amended every few years, most recently in 2026.
• Part P and competent person schemes. In England and Wales, much domestic electrical work is notifiable under Part P of the Building Regulations. Registering with a government-authorised competent person scheme, such as NICEIC, NAPIT or another approved scheme, lets your business self-certify that work instead of paying building control to inspect it. Expect an assessment of your qualifications, insurance, calibrated instruments and completed work before you join, then a yearly visit. The notifiable lists differ between England and Wales, so read the Part P guidance on GOV.UK.
• Scotland and Northern Ireland. Part P does not apply in Scotland, where domestic electrical work comes under the building standards system, a building warrant may be needed and approved certifier schemes run by SELECT and NICEIC let registered electricians certify compliance. Northern Ireland currently has no equivalent statutory requirement for domestic installation work. The IET summarises the position for Scotland and Northern Ireland.
• Inspection, testing and landlord EICRs. Private landlords in England must have the fixed wiring inspected and tested at least every five years by a qualified and competent person, and Scotland, Wales and Northern Ireland have their own five-yearly rules. To issue Electrical Installation Condition Reports credibly you need a recognised Level 3 inspection and testing qualification, and agents increasingly look for a scheme registration covering periodic inspection.
• EV chargers, solar and batteries. Installing chargepoints under the government grant schemes, where they are open, requires authorisation from the Office for Zero Emission Vehicles, and solar and battery storage work is usually expected to be MCS certified before customers can claim export payments or grants. Both need extra training and assessment, so add them later unless you already hold them.
• Waste carrier registration. If old consumer units, cable, fittings and packaging leave the job in your van, you usually need to be registered as a waste carrier with the Environment Agency in England, Natural Resources Wales, SEPA in Scotland or the Northern Ireland Environment Agency. Registering is simple, and carrying waste without it is costly.

Setting Up the Business

• Sole trader or limited company. Sole traders register with HMRC for Self Assessment and keep the admin light. A limited company is set up at Companies House, files accounts, pays Corporation Tax and keeps your personal finances separate from the business. Many electricians start as sole traders and incorporate once income is steady. Take an accountant's advice before you register anything.
• HMRC, VAT and the Construction Industry Scheme. Register with HMRC as soon as you start trading and set money aside for tax. VAT registration is compulsory once turnover passes the threshold published on GOV.UK, and some electricians register early to reclaim VAT on the van and instruments, which only helps if your customers are VAT registered too. Subcontracting to builders brings you into the Construction Industry Scheme.
• Bank account, bookkeeping and certification software. Open a business bank account before the first job and run everything through it. Choose bookkeeping software that handles quotes, invoices and receipts, and certification software or your scheme's system for the certificates and reports you issue. Making Tax Digital for Income Tax is being phased in for sole traders above a qualifying income published on GOV.UK, so keep digital records from the start.
• Insurance. Public liability insurance is the minimum, and schemes and letting agents will ask for the certificate. Employers' liability insurance is required by law as soon as you employ anyone, including an apprentice or a mate paid by the day. Add cover for the van, tools and test instruments, which thieves target, and consider professional indemnity if you design installations or issue condition reports.
• Wholesaler accounts and materials. An account with one or two electrical wholesalers brings trade prices, credit once you have a trading history, and a record of what each job cost in materials. Decide whether materials are built into a fixed price or itemised with a margin, because that decision runs through every quote. Keep van stock modest, since cable in racking is cash you cannot spend.
• Data protection and the legal details. You will hold names, addresses, access arrangements and certificates for every property you work in, so you need a short privacy notice and secure storage, and most businesses must pay the data protection fee to the Information Commissioner's Office unless an exemption applies. Your van, invoices and website should carry your trading name, and a limited company must show its registered name and number.

Start-up Costs and What You Need

The largest early costs are the van, the test instruments and the registrations. A reliable van, bought, financed or leased, needs commercial insurance, racking, livery and secure storage for the instruments, which are the next item: a multifunction tester, voltage indicator and proving unit, clamp meter and the yearly calibration, with records kept, that keeps them trustworthy and satisfies the scheme. Scheme assessment and membership, Wiring Regulations updates, insurance renewals and software subscriptions repeat every year, so treat them as running costs.

Then comes working capital. Materials are paid for at the wholesaler before the job and invoices settle weeks later, so you need enough in the account to cover living costs and the materials for several jobs at once. Fuel, parking, consumables, a phone, software, a website, a domain and the directory listings you choose to pay for all add up quietly.

Do not rely on a typical total. List every item you will need in your first year, get prices from suppliers and wholesalers yourself, and add a contingency for a van repair, a stolen tester or a rewire that overruns. That list is also the foundation of your day rate, because every item on it has to be recovered through the hours you charge.

Pricing Your Work

Start from your costs, not the market. Add together everything the business must pay in a year, including your own wage, the van, insurance, scheme fees, instruments, calibration and software, then divide by the number of days you can honestly charge for once quoting, travel, paperwork and quiet weeks are removed. The result is the day rate below which the business shrinks, and it is usually higher than expected.

Then decide how each kind of work is charged. Fault finding and small jobs usually carry a fixed first-hour or call-out charge with time after that, out-of-hours work a premium, and larger jobs such as consumer unit changes, rewires and chargepoint installations a fixed written quote. Condition reports are often priced by property size or circuits, and agents want a standard rate to quote to landlords. Take a deposit on large jobs so you are not funding the cable.

Quote in writing, say what is included and excluded and how long the price holds, and set out your terms for remedial work found during an inspection, which is the usual point of dispute on EICRs. Competing with the cheapest advert in town rarely works, because customers who choose that way also query every invoice. Registered, insured, tidy and on time is what most households and agents are paying for.

Finding Your First Customers

• People who already know you. Former colleagues, family, friends, neighbours and customers who followed you from your last job produce nearly every new electrician's first invoices, and their recommendations are the second source. Tell everyone you are trading, make your number easy to pass on and ask every happy customer for a Google review.
• Letting agents and landlords. Agents need condition reports, remedial work, alarm upgrades and fast fault repairs across their managed properties, and a landlord with a dozen flats can keep a sole trader busy for years. Visit local agents with your registration, qualifications and insurance certificate, offer a clear EICR price and quick turnaround, then be as reliable as you promised.
• Builders, kitchen fitters and other trades. Builders, kitchen and bathroom fitters and plumbers need an electrician who turns up when the first fix is ready and certifies the work. Subcontracting fills the diary while your own customer base grows, though margins are thinner and the Construction Industry Scheme may apply. Treat it as a bridge rather than the whole business.
• A Google Business Profile. Free and, for a local electrician, usually the listing that brings the most calls from strangers. Set it up as a service-area business with your name, number, the towns you cover and photographs of real work, and point it at a website, because people check before they call. Our guide to getting found on Google explains the basics.
• Scheme and directory listings. Your scheme's find-a-contractor search brings genuine enquiries at no extra cost. Checkatrade, Rated People, MyBuilder and similar platforms bring leads while you have no reviews elsewhere, but they charge for membership or per lead and put you in a price race. Trial one, record what each lead costs and let your reputation take over.
• Being visible where you work. A signwritten van outside a job, a card through the doors either side, a post in the local community group and a chat at the wholesaler counter all bring work over time. None of it replaces neat, certified work and an answered phone.

Your Website and Online Presence

An electrician's first website is proof rather than a brochure. A homeowner with a tripping circuit, or a landlord who needs a certificate by Friday, wants to see within seconds and on a phone that you are registered, insured, cover their town and can be called in one tap. A page per main service, a landlord EICR page if you are qualified for it, your registration and insurance details, photographs of tidy consumer units and your reviews are enough to launch, and chargepoint, solar and commercial pages can follow.

Have it live before you need it, because local rankings take months to build and the Google Business Profile that brings your calls needs a site to point to. If scheme registration is still pending, the site can launch describing your qualifications and insurance and gain the logo and number later. Our startup website checklist lists what to have ready.

Mistakes New Electrical Businesses Make

• Taking on notifiable work in England or Wales before scheme registration is confirmed, then finding the building control notification costs more than the job paid.
• Issuing condition reports without the qualification or experience behind them, the fastest route into a dispute with a landlord or their insurer.
• Pricing from what other electricians advertise rather than from your own costs, so the business is busy and still cannot pay you.
• Letting the instruments drift out of calibration and the certificates pile up unwritten, which the assessor notices at the annual visit.
• Mixing personal and business money and leaving the bookkeeping until the tax return is due.
• Depending on one builder or one letting agent for most of the work, so a single lost relationship empties the diary.
• Ignoring the Google Business Profile, reviews and website while you are busy, which is exactly when they should be bringing in next month's work.

Your First 90 Days

1. Gather your qualification certificates, your current BS 7671 certificate and any inspection and testing award, and check which notifiable work rules apply where you will trade.
2. Choose sole trader or limited company with an accountant's advice, register with HMRC or Companies House and decide what share of each invoice goes aside for tax.
3. Open a business bank account, choose bookkeeping and certification software and set up a wholesaler trade account.
4. Arrange public liability insurance, van, tool and instrument cover, and employers' liability if anyone will work for you, and register as a waste carrier if needed.
5. Apply to a competent person scheme, have the instruments calibrated and prepare the completed work and records the assessor will want to see.
6. Buy or lease the van, fit racking and security and have it signwritten, adding the scheme logo once registered. Our guide to startup logos and branding explains what to decide first.
7. Set your pricing: a day rate from your real costs, a first-hour or call-out charge, an out-of-hours rate, a standard EICR price and written terms for deposits and remedial work.
8. Register a .co.uk domain in your own name, set up a Google Business Profile and get a simple website live with your services, areas, registrations and phone number. Our domain name guide covers the checks.
9. Tell everyone you are trading, visit letting agents and local builders with your details, and trial one lead platform while tracking what each lead costs.
10. Photograph every job and ask every satisfied customer for a review, then at ninety days review where the work came from and what it paid, and adjust prices and marketing.
