Electrician insurance UK: what a self-employed sparky actually needs

TL;DR: Most self-employed electricians carry public liability insurance (usually £1m–£2m), and NICEIC's Domestic Installer scheme asks for at least £2 million. If you do EICRs under NICEIC, they also ask for at least £250k professional indemnity. Taking someone on? Read GOV.UK's employers' liability page first. On cost, Simply Business says the cheapest 10% of its electrician customers paid £80.40 or less a year for up to £2m public liability (Jan–Jun 2026).

Insurance is boring until a customer's ceiling comes down.

This pays out if your work injures someone or damages their property. A drill through a water pipe. A customer trips over your cable reel. A fire after a job.

In practice it's hard to trade without it:

• Your scheme asks for it. NICEIC says Domestic Installer applicants need a minimum of £2 million public liability in the registered trading name. If it's not in place on assessment day, they can't do the site assessment.
• Customers ask for it. Letting agents and commercial clients often want to see your certificate before you start.

How much cover? Simply Business says 66% of its electrician customers pick a £1 million limit and 34% pick £2 million. If you're joining NICEIC's Domestic Installer scheme, £2 million is the floor. If a contract asks for more, buy what the contract says.

PI covers claims that your advice, design or report caused someone a financial loss. For electricians, the big one is inspection and testing. If you miss something on an EICR and the landlord loses money, that's a PI claim, not public liability.

NICEIC says businesses certified to do EICRs need professional indemnity of at least £250k. Its Approved Contractor scheme, which covers periodic inspection and testing, lists £250k PI as a requirement to apply.

If you only do installation work and no inspection, design or advice, ask your broker if you need PI at all.

Before anyone works for you, even part-time, read GOV.UK's employers' liability insurance page and talk to your broker.

Practical checks:

• Ask how the broker treats subcontractors, labourers and family members who help out. It depends on how you work together.
• Get the certificate before the first day, not after an accident.
• Keep the certificate where staff can see it, and a copy on your phone.

GOV.UK's vehicle insurance page covers the basics. Two things to check with your insurer:

1. Tell them it's for business. Say what you carry and where you go. A policy for social use only may not cover driving to jobs.
2. Tools in the van. Many van policies don't cover the tools inside. That's usually a separate tools policy.

Your tester, your drills, your stock of cable. Losing them stops you working. Tools cover is optional, but price it up against what it would cost to replace your kit tomorrow.

When you compare policies, check:

• Is there cover overnight in the van? Some policies have conditions, like the van being locked or parked at home.
• Is it new-for-old or with wear and tear taken off?
• Is your test equipment covered at its real value?

These figures come from insurers and brokers, based on their own customers. They're not a survey of the whole market, and your quote will depend on your work, turnover, staff and claims history.

The useful number is the last one. A single claim can cost many times the premium.

1. List what you actually do. Domestic, commercial, EICRs, EV chargers, solar, work at height. Insurers price on this.
2. Check what your scheme asks for. Look up your scheme's current insurance rules. NICEIC's are on its scheme pages.
3. Check what your customers ask for. Some contracts set a minimum. Get it in writing.
4. Get at least three quotes. Use the same limits and the same job list each time so you're comparing like with like.
5. Read the exclusions. Ask about heat work, height limits, work on commercial sites, and subcontractors.
6. Keep the certificate handy. Have a PDF on your phone. Letting agents will ask for it.
7. Diary the renewal date. NICEIC says if compliant cover isn't in place on assessment day, it has to book an extra, chargeable assessment.

The Electrician Business Documents — Premium (£19.99) includes a Business Insurance Declaration and an Accident & Incident Report template, among its 17 business-record templates. They help you show customers your cover and record anything that goes wrong. The Electrician Startup Guide (£4.99) covers insurance alongside competence, Part P boundaries and voluntary scheme options. Neither is insurance advice.

In practice, yes. NICEIC asks for at least £2 million for its Domestic Installer scheme, and many customers and agents won't book you without it.

It depends on your work and your limits. Simply Business says the cheapest 10% of its electrician customers paid £80.40 or less a year for up to £2m public liability in January to June 2026. MoneySuperMarket, using Simply Business data for 2024 policies, says 51% paid £88.30 or less. Get your own quotes.

Most start with public liability. Ask about professional indemnity if you do EICRs or design work. Check GOV.UK's employers' liability page before anyone works for you. Make sure your van policy covers business use. Tools cover is worth pricing.

NICEIC says businesses certified to do EICRs need at least £250k professional indemnity. Other schemes set their own rules, so check yours.

It may be for some domestic work, but NICEIC's Domestic Installer scheme asks for £2 million. Simply Business says 34% of its electrician customers chose £2 million. Buy at least what your scheme and your contracts ask for.
