Do I need public liability insurance as a sole trader?
It isn't a legal requirement in the UK, but you probably need it if you work in clients' homes or premises, meet the public, or if any client, council, venue or landlord asks for it, which many do. Public liability covers injury and property damage claims from third parties. Typical 2026 premiums are about £106 a year for £1m, £118 for £2m and £140 for £5m, and low-risk sole traders can pay £50–£65. It sits alongside the other cover in what insurance does a sole trader need.
- Public liability is voluntary for sole traders but often required by contract, typically at £1m, £2m or £5m.
- As a sole trader you're personally liable, so an uninsured claim is paid from your own savings and assets.
- It covers third-party injury and property damage, not financial loss from advice (that's professional indemnity) and not your own tools.
- Moving from £1m to £2m typically costs only around £15–£20 a year.
- Describe your trade accurately. Work outside the declared occupation may not be covered.
When a Sole Trader Really Needs Public Liability
1. Do you work on other people's property? Cleaners, decorators, gardeners, electricians and mobile hairdressers all do.
2. Do members of the public come to you? Market stalls, studios, home salons and pop-ups.
3. Does anyone require it? Councils, letting agents, event organisers, facilities managers and larger clients commonly ask for a certificate before you start.
If any answer is yes, public liability is close to essential. A home-based copywriter who never meets clients may need professional indemnity insurance far more. The full picture is in what insurance do I need as a sole trader.
A sole trader is the business. A £40,000 injury claim from a client's slip on a wet floor you just mopped is a personal debt if you're uninsured. See sole trader vs limited company insurance.
How Much Cover, and What It Costs
• £1m: ~£106 a year
• £2m: ~£118 a year
• £5m: ~£140 a year
• Low-risk sole traders (personal trainers, tutors, cleaners): ~£50–£65
Price depends on trade, turnover, location, claims history and your chosen excess. Work on roofs, with heat or with gas pushes premiums up; see gas engineer public liability insurance for one specialist example. Use the Coverage Calculator to sanity-check the limit your contracts imply.
What Public Liability Won't Cover
• Financial loss from advice or errors: professional indemnity.
• Faulty goods you made or sold: often bundled, but check for product liability.
• Your own tools, van or stock: separate property cover.
• Accidents on the road: your motor policy, rated for business use.
Also check for an exclusion on work at height, heat work or specific locations. If clients visit you at home, the home insurance angle is covered in working from home as a sole trader, and the premium is normally a tax-deductible business expense.
Public liability pays other people. If you're the one injured and can't work, it pays you nothing; that gap is filled by income protection for the self-employed.
Illustrative Case: The Window Cleaner's Bucket
Scenario: A sole-trader window cleaner in Leeds leaves a bucket on a shop's front step. A customer trips, fractures a wrist and claims for injury and lost earnings. The cleaner holds £2m public liability, bought for about £120 a year because the shop's facilities manager required it.
Resolution & Judicial Outcome: The insurer handles the claim and pays compensation and legal costs, less any policy excess. Without cover, the settlement would have been a personal debt of the sole trader.
What You Should Do: Step-by-Step Action Plan
Critical Mistakes to Avoid
- Assuming it's illegal to trade without it, or that you don't need it because it isn't compulsory.
- Buying £1m when your biggest client's contract requires £2m.
- Expecting public liability to cover professional advice or your own tools.
- Under-describing your trade to get a cheaper quote.
