Public liability insurance explained

Written and reviewed by Sanjeev Yoganathan · Last reviewed 10 June 2026

What is public liability insurance?

Public liability (PL) insurance covers your business if a third party — a customer, member of the public, or visitor — suffers injury or property damage as a result of your business activities. It covers the cost of legal defence and any compensation awarded.

Who needs public liability insurance?

Any business that interacts with clients, customers, or the public — whether at its own premises or at client sites — should consider public liability insurance. This includes: tradespeople; retailers; food and hospitality businesses; event organisers; consultants; and contractors. It is frequently a contractual requirement.

Public liability vs employers' liability

Public liability covers claims from third parties (customers, members of the public). Employers' liability (EL) covers claims from your own employees if they are injured or become ill as a result of their work. EL insurance is a legal requirement for most employers in the UK, with a statutory minimum cover of £5 million.
