How to Start an Electrician Business in the UK: The Complete Guide
If you want to know how to start an electrician business in the UK, the first thing to understand is that notifiable electrical work requires registration with a competent person scheme – without it, you cannot legally self-certify domestic electrical work, and your customers face building control involvement for every job. Getting this right from day one is what separates a professional electrician business from one that undercuts on compliance.
This guide covers every step: competent person scheme registration, insurance, business setup, finding customers, and building a profitable electrical business.
The UK Electrical Market in 2026
Starting an electrician business in 2026 is commercially well-timed. The UK electrical industry faces a persistent skills shortage – demand for qualified electricians consistently outstrips supply across domestic, commercial, and industrial sectors. Key market drivers include:
- EV charger installations (one of the fastest-growing domestic electrical segments)
- Solar PV electrical work and battery storage
- Consumer unit upgrades and EICR surveys
- New build first and second fix
- Smart home and lighting control systems
- Commercial fit-out and maintenance contracts
A well-positioned electrician business can command premium rates and stay fully booked within months.
Step 1: Competent Person Scheme Registration
Starting an electrician business for domestic work requires registration with an approved competent person scheme. This allows self-certification of notifiable electrical work under Part P of the Building Regulations without separate building control involvement.
Main schemes for electricians:
| Scheme | Notes |
|---|---|
| NICEIC | Largest UK electrical scheme, widely recognised |
| NAPIT | Strong in electrical and renewables |
| ELECSA | Part of the NICEIC group |
| STROMA | Energy and renewables focus |
Requirements for registration: relevant electrical qualifications (18th Edition + NVQ Level 3), public liability insurance, and a technical assessment by the scheme. See gov.uk’s competent person schemes list for all approved schemes.
Step 2: Register Your Electrician Business
Sole trader: Register with HMRC at gov.uk/register-for-self-assessment – free. Receive a UTR within 10 days. File Self Assessment annually.
Limited company: Register at Companies House – £50. Better for commercial contracts and limits personal liability. Budget £800-1,500/year for an accountant.
Put aside 25-30% of all income for tax. See HMRC’s self-employment guidance for full details.
Step 3: Insurance for an Electrician Business
| Insurance | Minimum | Why essential |
|---|---|---|
| Public liability | £2m (£5m for commercial) | Electrical faults can cause fires and significant property damage |
| Professional indemnity | £1m | Covers system design and specification errors |
| Employers liability | £10m | Legally required if you employ anyone |
| Tools insurance | Replacement value | Test equipment, tools, and meters are high-value |
Ensure your policy explicitly covers electrical installation work. Get quotes from Simply Business or NICEIC Insurance.
Step 4: Qualifications for Starting an Electrician Business
The foundation qualifications for starting an electrician business:
- NVQ Level 3 in Electrotechnical Technology (or equivalent) – the core trade qualification
- 18th Edition IET Wiring Regulations (BS 7671: 2382-22) – current wiring regulations, renewed every few years
- City & Guilds 2391 (Inspection and Testing) – required for EICR surveys
- AM2 assessment – practical skills assessment required for most NVQ routes
See City & Guilds electrical qualifications for qualification routes.
Step 5: Finding Your First Customers
When starting an electrician business, initial customers come from:
Google Business Profile: Set up immediately at business.google.com. Emergency electrical searches (“electrician near me”, “fuse box replacement [town]”) are high-frequency and high-value.
Lead platforms: Checkatrade, Rated People, and MyBuilder all work well for electrical work. Customers specifically look for NICEIC or NAPIT registered electricians.
Letting agents and landlords: EICR (Electrical Installation Condition Report) surveys are legally required for rental properties every 5 years. One property manager with 30 properties is a significant recurring revenue source.
Builders and developers: Getting on a builder’s approved subcontractor list provides consistent new build work.
Conclusion
Starting your own trades business is one of the most financially and personally rewarding things a skilled tradesperson can do. The foundations – the right structure, the right insurance, the right systems – take a few weeks to set up properly, but getting them right from the start saves significant time and money further down the line.

Frequently Asked Questions
Do you need qualifications to start an electrician business in the UK?
Yes, effectively. Notifiable domestic electrical work requires registration with a competent person scheme, which requires relevant qualifications. Without registration, every job must be notified to building control – commercially impractical. See NICEIC’s registration requirements for full details.How much can an electrician business earn?
A sole trader electrician business typically earns £45,000-£85,000 per year. Businesses with EV charging and solar qualifications earn at the higher end. A small electrician business with a team of 2-3 can turn over £300,000-£600,000 annually.How long does it take to start an electrician business?
If already qualified with 18th Edition and NVQ Level 3, competent person scheme registration takes 4-8 weeks. If starting from scratch, allow 3-5 years for the apprenticeship and qualification pathway before registering your own business.Related reading:
