£5m Public Liability Insurance

No. There’s no statutory minimum for public liability insurance in the UK. £5 million is usually required by a council, principal contractor, venue, or client contract, rather than by law. Employers’ liability insurance is the one that’s legally required, and is itself fixed at a £5 million minimum for most employers.

The core cover works the same way, both pay out for third-party injury or property damage claims up to the stated limit. The difference is who tends to require each level: £2 million is often enough for smaller trades and mobile businesses, while £5 million is the common benchmark for council contracts, principal contractors, and larger commercial or public sector work.

Possibly, if you work on larger construction sites, major infrastructure projects, or for principal contractors who specifically require it. £10 million is typically reserved for higher-risk or higher-value contracts than £5 million usually covers.

Possibly, check your contract terms. Many policies exclude claims arising from subcontracted work if the subcontractor doesn’t hold their own public liability cover, so it’s worth confirming whether your policy extends to their work or whether you need to require proof of their own insurance.

A minimum indemnity limit of £5 million has been considered standard practice for local authority contracts since 1988, reflecting the potential scale of claims on public sector and larger commercial work. Some councils, such as West Sussex County Council, set their own minimum higher still, so always check the specific contract rather than assuming a round figure applies.

It varies by trade, site risk, turnover, and claims history, there’s no fixed price. Moving from £2 million to £5 million is often a smaller jump in cost than businesses expect, particularly for lower-risk trades with a clean claims record. Compare quotes for a price based on your own business.

Yes. Cover level isn’t tied to business structure, sole traders, partnerships, and limited companies can all buy £5 million cover, though sole traders more commonly need it when bidding for contract work that specifies the requirement.

Claims at this level often involve either multiple people affected by one incident, or damage to higher-value property, such as a contractor damaging underground utilities on a council site, where repair costs and third-party disruption claims can run into six figures once legal and business interruption costs are added. This is why £5 million is commonly set as a minimum on contract and public sector work rather than lower tiers.

Some specialist brokers offer short-term or single-event public liability cover at this level, useful if you only need proof of insurance for one contract or event rather than a full annual policy. Availability varies by insurer and trade.

It doesn’t cover injuries to your own employees, damage to your own tools or property, professional negligence, or usually damage to the specific item or structure you’re actively working on. Each of these typically needs a separate policy, such as employers’ liability, contractors’ all risks, or professional indemnity.

If you employ anyone, even part-time or casual staff, employers’ liability insurance is a separate legal requirement, currently fixed at a £5 million minimum for most businesses. Public liability and employers’ liability cover different things and are usually bought together but are not interchangeable.

Many insurers can issue a certificate of insurance the same day or within a few working days of the policy starting, though this varies by provider. If you’re working to a tender deadline, it’s worth checking certificate turnaround time before you choose a policy, not just the price.

Yes, if your business causes an injury, the NHS can separately claim treatment costs, including ambulance costs, from you under this scheme. This is typically absorbed within your £5 million public liability cover rather than being an additional bill you’re left to pay yourself.

Business insurance, including public liability, is generally treated as an allowable business expense for UK tax purposes, though individual circumstances vary. Check with an accountant or HMRC guidance for advice specific to your business.
