What Is Public Liability Insurance?
Public liability insurance covers claims from third parties — a client, visitor or member of the public — for injury or property damage connected to your work. Here's the part the industry tends to blur: it is not a legal requirement in the UK. You can legally trade without it. What makes it near-essential is that clients, contractors, landlords, trade platforms and some licences won't let you work without proof of cover, commonly at £1m, £2m or £5m. Those levels are set by the contract in front of you, not by any statutory minimum.
Not mandated by statute
Often £1m–£5m by contract
Strongly recommended
The £1m/£2m/£5m figures are cover levels required by contracts and clients — they are not statutory minimums. There is no legal minimum for public liability insurance, because it isn't required by law.
What public liability insurance covers
Public liability responds when your business activity causes injury to a third party or damage to their property — someone who isn't you or your employee. A visitor trips over a cable you left out; you knock over and break something in a client's home; a member of the public is hurt near where you're working. The policy is designed to cover the third party's claim, typically leaving you the excess.
It's distinct from the cover for your own staff. Injuries to your employees fall under employers' liability, which — unlike public liability — is required by law once you employ anyone (see do I need employers' liability insurance?).
Is it a legal requirement? (No — and this matters)
There's no legislation forcing a business to hold public liability insurance. You can legally trade without it. What makes it near-essential isn't the law — it's the people you work for. Most commercial clients, main contractors, property managers, trade platforms and some local-authority licences simply won't let you start work without seeing a valid certificate. So when someone says you “must” have public liability, they usually mean their contract requires it — which is a different thing from the law requiring it, and worth being clear about.
How much cover: the £1m/£2m/£5m levels are contract-driven
Because there's no legal minimum, the amount of cover is set by whoever is asking you to have it. Cover is commonly required at £1m, £2m or £5m depending on the client and site: commercial and construction contracts frequently specify £5m, while £2m is a common baseline for domestic work. Treat the figure in your contract as the target — not because a statute sets it, but because that's the level the contract won't proceed without.
Who typically needs it — and who may not
As a rule of thumb, the more contact your work involves with clients, the public or their property, the harder public liability is to do without. It's near-standard if you:
- enter clients' homes or premises to do the work
- have premises — a shop, salon, studio or office — that clients or the public visit
- work on commercial or construction sites, or list on trade platforms, where proof of cover is usually mandatory
- meet clients or the public face-to-face, or work at events
A purely remote business — no client visits, no premises the public enter, and no contract requiring cover — may have little public liability exposure. But that changes the moment a client, landlord or platform asks for it. If you're not sure which side of the line you're on, the checker below will tell you based on your actual setup.

Frequently asked questions
Is public liability insurance a legal requirement in the UK?
No. There's no UK law requiring a business to hold public liability insurance — you can legally trade without it. When you're told you must have it, that requirement comes from a client contract, a main contractor, a commercial landlord, a trade platform or a licence, not from statute.
What does public liability insurance cover?
It covers claims from third parties — a client, visitor or member of the public — for injury or property damage connected to your work. Typical examples are a visitor tripping over your equipment, or accidentally damaging a client's property while working on their premises.
How much public liability cover do I need?
There's no legal minimum, because it isn't required by law. Cover is commonly required at £1m, £2m or £5m depending on the client and site: commercial and construction contracts frequently specify £5m, while £2m is a common baseline for domestic work. The level is set by whoever is asking you to have it, not by statute.
Who needs public liability insurance?
In practice, anyone who has face-to-face contact with clients or the public, works on others' premises, or has premises the public visit. A purely remote business with no client visits, no public premises and no contract requiring cover may have little exposure — but as soon as a contract, landlord or platform asks for it, you need it to work.
Does public liability cover damage to the item I'm working on?
Not always. Standard policies often cover damage to a client's other property but may exclude the specific item or surface you were working on — the “care, custody and control” point. If that exposure matters to your work, check your policy extends to property in your care.

Public liability insurance is not legally mandated in the UK; the requirement to hold it typically comes from client contracts, contractors, landlords, trade platforms or licences rather than law. That's the opposite of employers' liability insurance, which is required by law once you employ anyone (minimum £5m cover) under the Employers' Liability (Compulsory Insurance) Act 1969 — see do I need employers' liability insurance? for that side of the picture.
