What Is Public Liability Insurance?
Public liability insurance (also known as PL insurance or PLI) is a type of business insurance that protects your business against financial claims made by members of the public, including customers, clients, suppliers, and bystanders, if they suffer injury, illness, or property damage as a result of your business activities.
It covers two primary types of claims:
- Personal injury claims: A customer slips on a wet floor in your shop, a client trips over equipment you left at their home, or a member of the public is injured at an event you organized.
- Property damage claims: You accidentally damage a client’s belongings while working at their property, a subcontractor damages a neighbouring property during a building project, or your delivery vehicle scrapes another car in a car park.
Crucially, public liability insurance covers both the cost of legal defence and any compensation awarded against your business. In serious injury cases, these costs can run into hundreds of thousands or even millions of pounds.
Is Public Liability Insurance a Legal Requirement in the UK?
With one notable exception, public liability insurance is not a legal requirement under UK law. The exception is horse-riding establishments, which must hold PLI under the Riding Establishments Act 1970.
However, being “not legally required” does not mean it is optional for most businesses. In practice, public liability insurance is often a contractual requirement.
- Local authority contracts: Councils may require £5 million or £10 million of public liability cover.
- Trade body membership: Some professional and trade associations require PLI as a condition of membership.
- Commercial landlord requirements: Many commercial leases require tenants to hold PLI.
- Venue hire: Event organisers, market traders, and craft fair stallholders may need to show proof of PLI.
- Client contracts: Larger businesses may require suppliers and contractors to have PLI.
- Public-facing events: Businesses organising events attended by the public will generally need appropriate cover.
Operating without insurance can expose a business to potentially significant uninsured losses.

Failure to hold the required employers’ liability insurance can result in significant fines.

Important considerations include:

- Review your policy annually: Your business activities, turnover, and staffing can change over time.
Frequently Asked Questions About Public Liability Insurance UK
Do I Need Public Liability Insurance If I Work From Home?
If clients visit your home office, you may need public liability insurance. Standard home insurance may not cover business-related claims.
If you work entirely online without clients visiting your home, your exposure may be lower, although PLI can still be worth considering.
What Is the Difference Between Public Liability and Professional Indemnity Insurance?
Public liability insurance generally covers physical injury and property damage claims made by third parties.
Professional indemnity insurance covers financial losses arising from professional errors, omissions, or negligent advice.
Some businesses, particularly consultants, accountants, architects, and IT professionals, may need both types of insurance.
Can I Get Public Liability Insurance for a One-Day Event?
Yes. Short-term or event-specific public liability insurance can be available for individual days or short periods.
It can be useful for market traders, craft fair stallholders, pop-up retailers, and event organisers.
Does Public Liability Insurance Cover Online Businesses?
For businesses operating entirely online without physical premises or face-to-face customer contact, public liability exposure may be relatively low.
However, PLI can still be relevant if you hold stock, deliver products, or meet clients in person. For businesses selling physical goods, product liability may also be important.
