What Is Public Liability Insurance in the UK? A Plain English Guide

What public liability insurance actually means

Public liability insurance protects your business against claims made by members of the public, clients, visitors or other third parties who say they suffered injury or property damage because of your business activities. If someone trips over a cable on your stand at a trade fair, or a tradesperson accidentally floods a customer's kitchen, public liability insurance is the cover that responds.

The policy typically pays two things: the compensation (often called damages) awarded to or agreed with the injured party, and the legal costs of defending or settling the claim. Legal costs alone can run into tens of thousands of pounds, even where a business is ultimately found not to be at fault, so the cover for defence costs is often as valuable as the compensation element itself.

It is important to be precise about who counts as a third party. A "third party" is essentially anyone who is not you, your business, or your employees. Customers, suppliers, passers-by, delivery drivers and visitors to your premises are all third parties. Your own staff are not, which is why injuries to employees fall under a completely different policy.

What public liability insurance covers

The core of a public liability policy is built around two scenarios. The first is bodily injury: a third party is physically hurt as a result of your business activities or a defect at your premises. The second is property damage: a third party's property is damaged, lost or destroyed because of something your business did.

Alongside compensation, most policies cover the associated legal expenses, claimant costs, and sometimes the cost of putting things right where this reduces the overall claim. Many policies also extend to incidents that happen away from your own premises, for example at a client's home, a market stall or an event venue, which matters for mobile trades such as gardeners, handymen and caterers.

Some insurers bundle limited product liability cover into the same policy, which responds when goods you supply cause injury or damage after they leave your hands. Always read the schedule, because the headline "public liability" figure and the way product claims are treated can differ.

What it does not cover

A common and costly misunderstanding is assuming public liability is an all-purpose business shield. It is not. It does not cover injury to your own employees, claims about the quality of your professional advice, damage to your own tools or stock, or deliberate and criminal acts. The table below sets out the boundary clearly.

The "care, custody and control" exclusion catches a lot of people out. If you are working on or holding a customer's property at the time it is damaged, a standard public liability policy may exclude or restrict the claim. Trades that handle valuable items, such as removals firms or mobile mechanics, should check whether they need a separate extension.

Typical cover levels in the UK

Public liability cover is sold against a single claim limit, called the limit of indemnity. The standard tiers offered across the UK market as of 2026 are 1m, 2m, 5m and 10m pounds. For many sole traders and micro-businesses, 1m or 2m pounds is the starting point, but the level you actually need is often dictated by the people you work for rather than your own risk appetite.

Local authorities, schools, the NHS, housing associations and large construction principals frequently set a contractual minimum of 5m or 10m pounds before you can be added to an approved supplier list. Some trade associations and accreditation schemes have their own minimums. Because the difference in premium between 2m and 5m of cover is usually modest, many businesses choose a higher limit simply to keep more contracts open to them.

Choosing too low a limit is a real risk. A single serious injury claim, particularly one involving long-term care or loss of earnings, can exceed 1m pounds. If a claim is larger than your limit, you are personally responsible for the shortfall, which for a sole trader can put personal assets at risk.

Who needs public liability insurance

There is no general law in the UK that forces every business to hold public liability insurance. Despite this, it is one of the most widely held covers because so many situations make it effectively unavoidable. Any business whose staff or activities bring them into contact with the public, visit client premises, run a shop or stall, attend events, or invite customers onto their own site has meaningful exposure.

In practice you are likely to need it if you are a tradesperson, run a customer-facing shop or salon, cater or run hospitality, work in someone's home or garden, or hold any kind of public-facing event. Even office-based consultants are often asked for it as a condition of a contract. Landlords, market traders and many self-employed people across sectors carry it as standard.

It is worth stressing again that this is separate from employers liability insurance. If you employ anyone, even part-time or casual staff, you are legally required to hold employers liability cover of at least 5m pounds under the Employers Liability (Compulsory Insurance) Act 1969, with limited exceptions. Public liability does not satisfy that obligation.

What affects the cost

Premiums vary widely because insurers price the specific risk of your trade. There is no single national tariff. The main factors that influence what you pay include the following.

• Your trade and activities: a desk-based consultant presents far less public risk than a roofer or a children's play centre, and pricing reflects that.
• Limit of indemnity: moving from 1m to 5m or 10m pounds raises the premium, though usually less than proportionally.
• Turnover and size: higher turnover and more staff generally mean more exposure and a higher premium.
• Claims history: past claims can increase your premium or affect the terms offered.
• Location and premises: a high-footfall retail unit carries different risk to a home office.
• Excess: a higher voluntary excess usually lowers the premium, but means you pay more towards each claim yourself.

Because pricing is so trade-specific, two businesses with the same turnover can pay very different amounts. Be honest and complete when describing your activities: a non-disclosure or misrepresentation can give the insurer grounds to reduce or reject a claim under the Insurance Act 2015 and, for consumer policies, the Consumer Insurance (Disclosure and Representations) Act 2012.

How to check a provider is FCA authorised

Any firm selling, arranging or underwriting general insurance to UK customers must be authorised and regulated by the Financial Conduct Authority. Dealing with an authorised firm gives you regulatory protections and, in many cases, access to the Financial Services Compensation Scheme and the Financial Ombudsman Service.

To check, use the FCA Financial Services Register at register.fca.org.uk. Search the firm's name or its firm reference number, confirm the entry is current and shows the firm is authorised, and check that the activities listed cover insurance. Brokers and intermediaries should also appear, sometimes as appointed representatives of a principal firm. If a firm is not on the register and is offering insurance, treat that as a serious warning sign and do not proceed.

How to complain about your insurer

If you are unhappy with how your insurer or broker has handled a policy or a claim, the first step is to complain directly to the firm in writing and ask for its final response. Authorised firms must have a formal complaints procedure and generally have up to eight weeks to respond.

If you do not receive a satisfactory final response, or eight weeks pass without resolution, you can refer the complaint free of charge to the Financial Ombudsman Service. The Ombudsman is independent, and its decisions are binding on the firm if you accept them. It can consider complaints from consumers and from many small businesses and micro-enterprises, so most sole traders and small firms are eligible to use it.

Frequently Asked Questions

Is public liability insurance a legal requirement?

In most cases, no. There is no general UK law requiring every business to hold public liability insurance. However, it is often made compulsory by contracts, local authority licences, landlords or trade bodies, and many businesses cannot operate without it in practice. This is different from employers liability insurance, which is legally required for most employers.

How much public liability cover do I need?

The right level depends mainly on who you work for. Many small businesses start at 1m or 2m pounds, but public sector and large commercial contracts frequently require a minimum of 5m or 10m pounds. Because higher limits often cost relatively little more, many businesses choose 5m pounds to keep more contracts open to them and to protect against large injury claims.

What does public liability insurance not cover?

It does not cover injury to your own employees, claims about faulty professional advice, damage to your own property, contractual fines, or deliberate and criminal acts. It also often excludes or limits damage to property in your care, custody or control. Those risks need other policies such as employers liability, professional indemnity or property insurance.

How do I check if an insurer is FCA authorised?

Search the firm's name or reference number on the FCA Financial Services Register at register.fca.org.uk. Confirm the entry is current, shows the firm as authorised, and lists insurance activities. Brokers may appear as appointed representatives of a principal firm. If a firm offering insurance is not on the register, do not deal with it.

How do I complain about my insurer?

Complain to the insurer or broker in writing first and ask for a final response. If you are not satisfied, or eight weeks pass without resolution, you can refer the complaint free of charge to the Financial Ombudsman Service. The Ombudsman is independent and can consider complaints from consumers and most small businesses, with binding decisions if you accept them.
