What Is Public Liability Insurance
Public liability (PL) insurance covers a business against claims from third parties -- customers, clients, members of the public, visitors -- who suffer injury or property damage as a result of the business's activities. If a customer slips on a wet floor, a contractor damages a client's property, or a visitor is injured at your premises, PL insurance covers legal defence costs and any compensation awarded.
Is Public Liability Insurance Legally Required
Public liability insurance is not legally required for most UK businesses. Legal compulsion applies only to employers liability (for businesses with employees) and motor insurance (for vehicles on public roads). However, PL is commercially essential -- most commercial leases, client contracts, public sector frameworks, venue access agreements and trade association memberships require evidence of cover as a condition.
How Much Cover Do You Need
The appropriate PL cover level depends on the scale and risk profile of the business. Common benchmarks: £1 million for most small sole trader or home-based businesses. £2 million to £5 million for most SMEs with client-facing operations. £5 million to £10 million for local authorities, public sector bodies and large corporate clients. £10 million or more for construction, events and high-risk activities.
What Public Liability Insurance Covers
PL insurance typically covers injury to third parties on your premises or caused by your business activities, damage to third-party property caused by your business or employees, legal defence costs even where a claim is unfounded, and products liability covering injury or damage caused by goods you manufacture or sell. It does not cover employees (covered by EL insurance), damage to your own property, or contractual disputes.
Products Liability
Products liability insurance covers claims arising from products your business manufactures, supplies or sells that cause injury or property damage. It is typically included in a combined public and products liability policy. The Consumer Protection Act 1987 imposes strict liability on producers for defective products -- products liability insurance covers this exposure.

Frequently Asked Questions
Is public liability the same as employers liability?
No. Public liability covers claims from third parties -- customers, visitors, members of the public. Employers liability covers claims from your own employees. EL is legally required for businesses with employees; PL is not legally required but commercially essential.
What is the difference between public liability and professional indemnity?
Public liability covers physical injury or property damage to third parties. Professional indemnity covers financial losses caused by professional advice or errors. Most professional service businesses need both.
How much does public liability insurance cost for a small business?
A small sole trader in a low-risk service business might pay £80 to £200 per year for £1 million of PL cover. Higher-risk trades or those requiring higher cover levels pay more.
Does public liability insurance cover online businesses?
Yes. Online businesses can hold PL insurance. It is particularly relevant for e-commerce businesses selling physical goods, where products liability covers injury or damage caused by goods sold.
