Is public liability insurance a legal requirement in the UK?

No — unlike employers' liability insurance, public liability is not required by law. However, many clients, contracts, local authorities and trade bodies require it before you can start work, so in practice it is essential for most tradespeople and businesses that deal with the public.

Do self-employed people and sole traders need public liability insurance?

If your work brings you into contact with clients, customers or the public — on their premises or yours — a single accident can produce a claim far larger than your annual income. Public liability insurance for self-employed workers and sole traders is usually inexpensive relative to the protection it provides, and many clients will not hire you without it.

How much public liability cover do I need?

Cover limits typically range from £1 million to £10 million. Many commercial contracts and council tenders require £5 million or more. A specialist broker will size the limit to your contracts and the scale of work you take on rather than selling you a default figure.

Does public liability cover my employees?

No. Injuries to your own employees are covered by employers' liability insurance, which is a legal requirement if you employ anyone. Public liability covers third parties — customers, visitors and members of the public.

Do I need public liability insurance?

Public liability insurance isn't a legal requirement in the UK — but for most businesses that work with the public, a contract, client or trade body will require it before you can start the job. Here's how to work out whether you need it, and how much.

What public liability insurance actually covers

It pays out when a third party — a customer, a visitor, a passer-by — is injured or their property is damaged because of your work or premises. A client trips over your cable, a ladder scratches a customer's car, a burst pipe ruins the flat below: the policy covers your legal defence costs and any compensation you're liable for. Without it, those costs come straight out of your business.

Who needs it most

You're very likely to need public liability insurance if you:

Work in other people's homes or premises — builders, electricians, plumbers, cleaners, decorators.
Run a business the public visits — shops, salons, cafés, studios, gyms.
Tender for contracts — many commercial clients and councils won't award work without proof of cover, often at £5 million or above.
Belong to a trade body or accreditation scheme that requires it as a condition of membership.

Public liability insurance for the self-employed and sole traders matters just as much as for limited companies — a claim doesn't care about your business structure, and as a sole trader your personal assets are exposed too.

How much cover do you need?

Policies typically come with limits of £1m, £2m, £5m or £10m. The right figure depends on your contracts (check what limit your clients require), the environments you work in, and the worst-case damage your work could cause. A plumber working in a block of flats has a very different exposure to a market stallholder. Buying the cheapest £1m limit by default can leave you underinsured exactly when it matters.

Why a specialist public liability insurance broker beats a comparison site

Liability underwriters price on the detail of your trade: your activities, turnover, whether you use heat tools or work at height, your subcontractor arrangements and your claims history. Most specialist liability markets never appear on comparison sites at all. A public liability insurance broker who places trade risks daily presents your work accurately to the right underwriter — which is usually where the meaningful savings are, because misdescribed risks are priced on worst-case assumptions.

A broker also negotiates the things comparison sites can't: the excess you can actually afford to carry, endorsements around your real activities, and cover that holds up at claim time rather than just at quote time.
