If your business deals with the public, one slip or accident could lead to a costly compensation claim. Public liability insurance protects against exactly that. This guide explains public liability insurance in plain English: what it covers, who needs it, whether it is compulsory, and how much cover to choose.
What public liability insurance is
Public liability insurance covers claims made against your business by members of the public, customers, clients or other third parties, who suffer injury or whose property is damaged in connection with your business activities. If someone trips over your equipment, is hurt on your premises, or has their property damaged by your work, and you are held legally responsible, the policy pays the compensation and legal costs, up to its limit.
What it covers
A public liability policy covers the cost of defending a claim and any compensation or damages awarded, where your business is found liable for injury to a third party or damage to their property. That includes things like a customer injured by a falling display, a passer-by hurt near your work, or accidental damage you cause to a client's property while working. It is third-party cover; it does not cover injury to your own employees.
Who needs it
Any business that interacts with the public or works on others' premises should consider public liability cover. That includes shops, cafes and other premises the public visit, tradespeople working in customers' homes, and businesses whose staff are out and about. Even a small business can face a large claim if someone is seriously hurt, so the size of the business is no guide to the size of the risk it faces.
Is it compulsory?
Public liability insurance is generally not required by law, unlike employers' liability cover, as our guide to employers' liability insurance explains. However, it is often required in practice. Clients, landlords, local authorities and contracts frequently insist on it before they will work with you or let you on site. So while no statute forces most businesses to hold it, you may find you cannot trade without it.
Public liability and your contracts
It is common for contracts and clients to require a minimum level of public liability cover, often £1 million, £2 million or £5 million, before they will engage you. Larger organisations and public bodies may demand higher limits. So the cover you need is sometimes dictated not just by your own assessment of risk but by what your customers require. Check your contracts, as a missing or inadequate policy could cost you work.
How much cover to choose
Public liability cover is commonly offered at limits of £1 million, £2 million, £5 million or more. The right level depends on your activities, the size of the potential claims, and any contractual requirements. Higher-risk work, or work for larger clients, generally calls for a higher limit. Since the difference in premium between levels is often modest, many businesses choose a generous limit for peace of mind, especially where serious injury is possible.
Public liability versus product liability
Public liability is sometimes bundled with product liability, which covers claims arising from products you supply causing injury or damage. If your business makes, sells or supplies products, product liability cover is worth considering alongside public liability, since a faulty product can cause harm just as an accident on your premises can. Check whether a policy includes both, or whether you need to add product liability separately, depending on what your business does.
How it fits with other business cover
Public liability is one piece of a business's insurance, alongside employers' liability if you have staff, professional indemnity if you give advice, and cover for your premises and contents. Many insurers offer combined business policies bundling these together. Understanding what each covers, as our guides to professional indemnity and business contents and commercial property insurance explain, helps you build the right overall protection.
Examples of public liability claims
Public liability claims arise in everyday situations. A customer slips on a wet floor in your shop and is injured; a member of the public is hurt by tools or materials at your work site; you accidentally damage a client's property while carrying out a job. In each case, if you are found legally responsible, the costs of compensation and defending the claim can be substantial, and it is these third-party costs that public liability cover is designed to meet.
Tradespeople and working on others' property
For tradespeople and others who work in customers' homes or premises, public liability cover is particularly important, because the risk of injuring someone or damaging property is ever-present. A plumber who causes a flood, or a builder whose work injures a passer-by, could face a large claim. Many clients will also insist on seeing proof of cover before letting you start. For these trades, public liability is close to essential in practice.
Events and temporary cover
Public liability is also relevant for one-off situations, such as running a stall, holding an event, or doing temporary work, where members of the public are present. Some insurers offer short-term or event-specific public liability cover for exactly these occasions, so you are protected for the period without committing to an annual policy. If you are organising or taking part in a public event, it is worth checking whether such cover is needed or required.
Why even small businesses need it
It is a mistake to think public liability only matters for large businesses. A sole trader or small firm can cause exactly the same injury or damage as a big one, and face just as large a claim, but with far less ability to absorb the cost. A single serious claim could threaten a small business's survival. The modest premium for public liability cover is small set against the protection it provides against that risk.
A small premium against a large risk
The case for public liability comes down to proportion. The premium for cover is usually modest, while a single serious injury claim can run to very large sums that few businesses could absorb. For the cost of the cover, you remove a risk that could otherwise threaten the business itself. That is why so many businesses, large and small, treat public liability as a basic foundation of their insurance, even where no law or contract compels it.
In short
Public liability insurance covers compensation and legal costs if a member of the public is injured, or their property damaged, because of your business, and you are liable. It is not usually required by law, but clients, landlords and contracts often insist on it. Common limits are £1 million, £2 million or £5 million, sometimes set by your contracts. It is third-party cover and does not protect your own employees, for which you need employers' liability.
