How public liability insurance cover works in the UK

Public liability insurance responds when a member of the public brings a compensation claim against a business for personal injury, loss, or property damage connected to its activities. According to the Association of British Insurers, the cover typically pays the compensation awarded plus the legal costs of defending the claim. The policy protects third parties such as customers, visitors, and passers-by; it does not cover the business' own employees, who fall under employers' liability insurance instead.

Unlike employers' liability, public liability is not a blanket legal requirement in the UK. The ABI notes that the main statutory exception is a horse riding establishment, which is legally obliged to hold the cover. In practice, many client contracts, local authority permits, and trade body memberships require a minimum level of public liability cover before work can begin, which is why the ABI records it as the most widely held SME policy.

Cover is sold at fixed limits of indemnity, commonly £1 million, £2 million, £5 million, or £10 million, with the right level driven by the size of contracts a business takes on and the requirements set by its clients. Every insurer underwriting this cover in the UK must be authorised by the Financial Conduct Authority, and any rejected claim or dispute can be referred to the Financial Ombudsman Service once the insurer's own complaints process is exhausted.

How to compare public liability insurance objectively

Start with the limit of indemnity your contracts require. Many commercial clients and public bodies specify a minimum of £5 million or £10 million, so check tender and contract documents before choosing a level. A higher limit raises the premium but is fixed per claim period, so under-buying can leave a gap.

Read the exclusions before the headline price. Public liability does not cover employee injury, which is the separate compulsory employers' liability cover, and it does not cover professional negligence, which sits under professional indemnity. Check whether products you supply, work carried out away from your premises, and sub-contractors are included.

Verify the insurer or intermediary on the FCA Register at register.fca.org.uk before buying. The Register confirms a firm is authorised and shows the activities it is permitted to carry out. If you buy through a broker or comparison intermediary such as an FCA-authorised arranger, confirm both the intermediary and the underlying insurer are authorised. If a claim is later rejected and you disagree, the Financial Ombudsman Service can review eligible complaints once the insurer's complaints process is complete.
