UK Public Liability Insurance for Sole Traders Explained
If you work in other people's homes, run a market stall or meet clients face to face, sooner or later someone will ask: "Have you got public liability?" For UK sole traders it is not a legal requirement, but it is often a condition of getting the work. This explainer covers what public liability insurance does, what it does not, and how to choose a policy that fits. It is general information, not insurance or legal advice.
Key takeaways
- Public liability insurance covers claims from members of the public, clients and customers for injury or property damage caused by your business.
- It is not a legal requirement in the UK, but clients, venues, councils and main contractors frequently require it.
- It does not cover injury to you, your own tools, your employees or losses caused by bad advice.
- If you employ anyone, employers' liability is usually a legal requirement, with a minimum of £5 million cover.
- Choose your limit based on the contracts you sign and the work you do, and describe every activity accurately.
As a sole trader, you and your business are legally the same person. If a customer trips over your toolbox, or water from a pipe you fitted ruins a neighbor's ceiling, the claim lands on you personally. Without insurance, the compensation and legal costs could come from your savings or your home.
Public liability insurance exists to take that risk off your shoulders. It is one of the most common policies for self-employed people in the UK, and for many trades it is effectively the price of entry to bigger jobs. Below you will find what it covers, who needs it and how to buy it sensibly.
What public liability insurance covers
Public liability, often shortened to PL, responds when a third party claims your business caused them harm. A third party is anyone who is not you or your employee: customers, clients, passers-by, neighbors and other trades on site. A typical policy covers:
- Injury to third parties. A visitor trips over a cable at your craft stall, or a client is hurt by falling materials while you work in their home.
- Damage to third-party property. You knock over an expensive vase while decorating, or a leak from your plumbing work damages a kitchen.
- Legal costs. The cost of defending a claim, which can be significant even if the claim fails.
- Compensation awarded. Damages you are legally liable to pay, up to the limit of the policy.
Public liability is usually written on a "claims occurring" basis. That means the policy in force when the incident happened responds, even if the claim arrives later. Check your policy wording to confirm how yours works.
What it does not cover
Many sole traders assume public liability covers everything that might go wrong. It does not. Knowing the gaps helps you decide what else you might need.
| Situation | Covered by PL? | Cover to look at instead |
|---|---|---|
| Injury to an employee | No | Employers' liability |
| Your own injury or illness | No | Personal accident or income protection |
| Theft of or damage to your tools | No | Tools or business equipment cover |
| Client loses money because of your advice or design | No | Professional indemnity |
| Harm caused by a product you made or sold | Sometimes, if included | Product liability, often sold alongside PL |
| Cost of redoing faulty work itself | Usually not | Check contract works or guarantee options |
| Damage to your van or injury from driving | No | Business motor insurance |
Common mistake
Believing that public liability pays to fix your own poor workmanship. It is designed for injury and damage to others caused by your work, not for the cost of putting right the work itself. Read the exclusions section of your policy so you know where that line sits.
Do sole traders need public liability insurance?
Legally, no. Public liability insurance is not a legal requirement in the UK. In practice, many sole traders cannot work without it because the people who hire them insist on it.
Who commonly asks for it
- Main contractors who hire subcontracting trades.
- Councils and public bodies that require cover for suppliers and licensed traders.
- Event organizers and market operators who will not give you a pitch without a certificate.
- Venues and landlords where you run classes, workshops or treatments.
- Larger business clients whose procurement process lists insurance requirements.
Who should consider it even when nobody asks
Any sole trader who works in public spaces, visits clients' homes or premises, or has customers visit them carries a real risk. That includes electricians, plumbers, decorators, cleaners, gardeners, mobile hairdressers and beauty therapists, personal trainers, photographers, dog walkers, market traders and anyone who runs workshops or events. A home-based freelancer who never meets clients may have a lower need, but should still think through whether anyone visits.
Example
Imagine a self-employed decorator painting a hallway. A client's child runs past, knocks over a stepladder and is injured. The family makes a claim against the decorator. With public liability cover, the insurer handles the claim, pays legal costs and pays any compensation owed up to the policy limit. Without it, the decorator would face the full cost personally.
Public liability vs employers' liability
These two policies are easy to confuse, but the difference matters because one of them is a legal duty.
- Public liability covers claims from the public and clients. It is optional by law, but often required by contract.
- Employers' liability covers claims from your employees for injury or illness caused by their work. It is a legal requirement for most employers in the UK, with a minimum of £5 million cover.
As a sole trader working alone, you usually do not need employers' liability. The picture changes the moment you take someone on, even part-time, temporarily or casually. Laborers, apprentices and some subcontractors you direct and supply with tools may count as employees for this purpose. Some family arrangements are exempt. Because the rules depend on the facts, check the official GOV.UK guidance on employers' liability or ask a broker before anyone starts working for you.
How to choose the right policy
Public liability policies look similar on comparison sites, but small details make a big difference. Work through these steps:
- Check what your contracts require. Look at the insurance clauses in client contracts, pitch agreements and venue terms. Note the minimum limit and any special wording they ask for.
- Describe your trade accurately. Choose the occupation that matches your real work and list every activity, including occasional jobs. An unlisted activity may not be covered.
- Pick a limit of indemnity. This is the most the insurer pays for one claim. Match the highest limit your contracts require, then consider whether your work could cause a larger loss.
- Check the excess. Property damage claims often carry an excess you pay first. Make sure it is affordable.
- Read key exclusions. Look for limits on heat work, work at height, certain materials or work in particular locations.
- Add what you need alongside. Tools cover, product liability, professional indemnity or employers' liability may be offered in the same package.
- Keep your certificate handy. Save a copy on your phone so you can send proof quickly when a client or venue asks.
Pro tip
Some main contractors and public bodies ask for an "indemnity to principal" clause, which extends your cover to them for claims arising from your work. If a contract mentions it, check that your policy includes it before you sign, rather than discovering the gap when the paperwork is reviewed.
Annual cover or short-term cover
Most sole traders buy an annual policy. If you only trade at a few events a year, some insurers offer short-term or event cover. Compare the total cost across a year and check that the cover meets each organizer's requirements.
Tax treatment
Insurance bought wholly for your business is generally treated as an allowable business expense for sole traders. Keep the policy schedule and receipts with your records, and check HMRC guidance or an accountant if a policy mixes business and personal cover.

Frequently asked questions
Is public liability insurance a legal requirement for sole traders?
No. Public liability insurance is not required by UK law. It is often required by clients, venues, councils and main contractors, so in practice many sole traders need it to win work.
Does public liability cover me if I work from home?
It can cover claims from clients or couriers who visit your home for business. Check that your home insurer knows you run a business from home, as a home policy may exclude business visitors and equipment.
What if a claim arrives after my policy ended?
Most public liability policies respond on a claims occurring basis, so the policy in force when the incident happened usually deals with it. Keep old policy documents in case a late claim appears.
Do I need public liability if I only work online?
Your need may be low if no one visits you and you never visit clients. Professional indemnity or cyber cover may be more relevant. Think about meetings, events and any physical products before deciding.

For a UK sole trader, public liability insurance protects your personal finances from claims by the people you work around, and it often unlocks contracts that would otherwise be closed to you. It is not a legal requirement, but it is a practical one for most trades and client-facing services. Know its limits, add the cover it leaves out and arrange employers' liability before you hire.
