What is Public Liability Insurance?

Public liability insurance responds when a third party suffers loss as a result of your business operations. The two main categories of covered loss are personal injury (physical harm to a person) and property damage (damage to or destruction of someone else's property). Consequential financial loss suffered by the third party — such as lost revenue — is generally excluded unless specifically added to the policy.

The scope is broad: customers on your premises, delivery drivers, visitors, neighbouring businesses, and members of the public who are affected by your activities. Typical claims include a customer slipping on a wet floor, a contractor's equipment damaging a client's infrastructure, or a hospitality business causing a water leak that damages a neighbouring property.

Standard exclusions include: damage to goods in your own custody or control (which falls under goods-in-transit or storage insurance), deliberate damage, and in many policies, product liability for goods you have manufactured or supplied (which requires separate product liability cover).

The level of cover required varies by sector and type of work. A small office-based business may need only £1 million in coverage; a contractor working on large construction sites may be contractually required to carry £5 million or more. Many public sector procurement processes require minimum coverage levels as part of the qualification criteria.

For buyers, requiring proof of valid public liability insurance from contractors and service providers who work on your premises or with your clients is a basic supply chain risk management measure. An uninsured contractor who causes harm can expose the commissioning business to liability in addition to the direct harm caused.

A single third-party liability claim — a visitor injured on your premises, or property damaged during a project — can result in costs that threaten business continuity without insurance. Public liability cover is one of the most cost-effective protections available to SMBs.

As a buyer, requiring evidence of adequate public liability cover from your suppliers and contractors is straightforward protection. If an uninsured contractor causes harm, your business may face claims that would otherwise have been absorbed by their insurer.
