Public liability insurance can help protect a business if a customer, visitor or other member of the public claims its activities caused them injury, illness or property damage. It is generally not required by UK law, but a venue, client or landowner may make it a condition of working or hosting an event. It is separate from employers’ liability insurance, which covers work-related injury or disease suffered by employees and is generally compulsory for covered employers.
What is public liability insurance?
Public liability insurance is business cover for claims from people the business does not employ. A claim might allege that the business’s work, premises or event caused bodily injury, disease or damage to someone else’s property. GOV.UK describes it as protection against claims that a member of the public was injured or their property damaged because of business activities; the Association of British Insurers (ABI) likewise distinguishes it from cover for employees.
For example, a customer could claim they were hurt in a shop, a contractor could face a claim after allegedly damaging a client’s property, or an event organiser could be sued over an injury at an event. Whether a particular claim is covered depends on the policy wording, its exclusions and the circumstances.
Is public liability insurance compulsory in the UK?
There is no general UK law requiring every business to buy public liability insurance. However, a council, landowner, venue or client may require it as a condition of using a site, holding an event or taking on a contract. GOV.UK’s guidance for voluntary events says the insurance is not compulsory in law for that type of event, while noting that a venue or other party may require cover (GOV.UK event guidance).

That practical requirement can be decisive: a business may need a policy to meet a contract or venue condition even though the law does not generally require public liability cover. Ask the organisation specifying the requirement what limit and scope it expects.
What does public liability insurance cover?
The central distinction is who brings the claim: public liability is for third parties, rather than people the business employs. Depending on the wording, it may respond to allegations of bodily injury, disease or damage to third-party property connected with the insured business activities. It is not a guarantee that every incident, loss or claim will be covered; check the policy’s exclusions, conditions and definitions.
Before buying, verify that the policy names the right business and covers the work actually carried out. Relevant details can include the services or trades performed, events organised, premises and sites used, and whether workers or volunteers need to be included. GOV.UK advises event organisers to make sure their insurance covers the activities they carry out and to check its terms and exclusions.

| Cover | Whose claim it addresses | What it concerns | Is it generally required by law? |
|---|---|---|---|
| Public liability | People the business does not employ, such as customers, visitors or members of the public | Alleged injury, disease or damage to their property linked to business activity | No general legal requirement for every business; a contract, venue or landowner may require it. |
| Employers’ liability | Employees | Work-related bodily injury or disease suffered by people the business employs | Generally compulsory for covered employers in Great Britain. |
The Employers’ Liability (Compulsory Insurance) Act 1969 establishes the compulsory-insurance requirement for covered employers in Great Britain. GOV.UK states that employers’ liability insurance must provide at least £5 million of cover. That minimum applies to employers’ liability, not automatically to public liability. GOV.UK also states that failing to have required employers’ liability insurance can result in a £2,500 fine for each day without it, and failing to display the certificate can result in a £1,000 fine (GOV.UK employers’ liability guidance).
How much public liability cover do you need?
There is no single statutory public-liability limit that suits every business. The appropriate limit depends on the nature of the work, the people and property exposed to risk, and any contractual or venue requirements. For voluntary events, GOV.UK says limits can start at £1 million and rise depending on the event type, activities and expected attendance (GOV.UK voluntary-event insurance guidance). This is event-specific guidance, not a universal minimum or recommendation for every trade.
- Check the exact limit specified by a client, venue, council or landowner.
- Consider the potential scale of injury or property-damage claims arising from the work or event.
- Confirm that the limit applies to the activities, people and locations involved.
- Read how the policy treats legal defence costs, settlements and the excess; these details vary by policy wording.
GOV.UK’s event guidance gives illustrative premium examples of around £50–£60, but these are not market-wide average prices and should not be treated as estimates for other businesses. Premiums and suitable limits depend on the specific risk and cover requested.

- Activities declared: Describe all work, services, premises and events accurately. A policy may not protect activity outside the scope it covers.
- Limit of indemnity: Match the limit to the realistic risk and any client or venue requirement; there is no universal public-liability statutory minimum.
- Exclusions and conditions: Check what is excluded and any requirements concerning safety, supervision, subcontractors or how incidents must be reported.
- Who and where are insured: Check the named business, workers or volunteers, locations and territorial scope against the actual operation.
- Claims handling: Confirm how the insurer handles investigation, legal defence, settlement and the excess rather than assuming those terms are the same across policies.
- Contractual requirements: Compare the policy wording and limit with the exact terms imposed by clients, venues or landowners.
GOV.UK recommends speaking with an insurer or broker about event cover and points readers to the British Insurance Brokers’ Association (BIBA) to find a broker (BIBA broker finder). A broker or insurer can help assess the stated activities and requirements, but the policy wording remains the place to verify what is covered.
Who may want to consider public liability cover?
Any business whose work brings it into contact with customers, visitors, clients’ property or public-facing events can consider whether this cover is appropriate. The exposure differs: a sole trader working in customers’ homes, a shop receiving visitors, a contractor at a client site and an event organiser do not necessarily need identical terms or limits. A contract or venue requirement may settle the question even when the law does not.
