Public Liability Insurance UK: What It Covers, Limits and FCA Regulation

What public liability insurance actually covers

Public liability insurance responds when a third party, meaning a member of the public, a customer or a client, suffers injury or has their property damaged in connection with the business, and the business is found legally liable. Typical examples include a customer slipping on a wet shop floor, a passer-by hurt by falling signage, or a tradesperson accidentally damaging a client's home while carrying out work. The policy pays the compensation awarded plus the legal costs of defending or settling the claim.

The cover is built around legal liability. It does not pay out simply because an accident happened: the business generally has to be at fault or otherwise legally responsible. Where liability is established, the insurer steps into the shoes of the business to handle the claim, which is valuable because legal defence costs alone can be substantial even for a claim that is ultimately defended successfully.

Crucially, public liability covers third parties only. Injuries to the business's own employees are dealt with by employers' liability insurance, which is a separate and legally required cover for firms with staff. Damage to the business's own property is covered by commercial property insurance, not public liability. Understanding these boundaries prevents an assumption that one policy covers everything.

What it does not cover

Public liability has clear exclusions. It does not cover claims arising from professional advice or services, which fall under professional indemnity insurance. A consultant whose advice causes a client financial loss needs professional indemnity, not public liability, because no physical injury or property damage may be involved. Confusing the two is a common and costly gap.

It also does not cover defective products in the way product liability insurance does, though many policies bundle public and product liability together. Damage to property in the business's care, custody or control is frequently excluded or limited, which matters for trades working inside a client's home or holding a client's goods. Employee injuries, the business's own losses, and contractual penalties also sit outside public liability.

Reading the schedule of exclusions and any conditions, such as requirements to use particular safety measures, is essential. A claim can be reduced or refused if the business breached a policy condition, for instance failing to maintain equipment or ignoring a heat-work warranty for tasks involving naked flames.

Choosing the right limit of indemnity

The limit of indemnity is the maximum the insurer will pay for a covered claim, and choosing it well is the single most important decision. Common levels are 1 million, 2 million, 5 million and 10 million pounds. For many small firms the practical driver is not guesswork but contract requirements: public sector bodies, large clients and many commercial contracts specify a minimum public liability limit, often 5 million or 10 million pounds, before they will engage a supplier.

The right level reflects the realistic worst case. A business working on or near other people's high-value property, in crowded public spaces, or in higher-risk trades faces larger potential claims and usually needs a higher limit. A serious injury claim can run well beyond a million pounds once long-term care and loss of earnings are included, so a low limit may leave the business exposed to the excess above it.

Buyers should also check whether the limit applies per claim or in the aggregate across a policy year, and what the policy excess is. A high headline limit that is eroded by multiple claims in a year, or paired with a large excess, may offer less protection than it first appears.

Who needs it and how cost is shaped

Public liability is most relevant to any business whose activities bring it into contact with the public or with clients' premises: shops, hospitality, tradespeople, event organisers, cleaners, gardeners, market traders and consultants who visit client sites. Office-only businesses with little public contact have lower exposure, but even they may need cover for visitors or for working at client locations.

The premium reflects the assessed risk. Insurers weigh the trade and its hazard level, the chosen limit of indemnity, turnover and number of staff, claims history, and where and how the work is carried out. A roofer working at height presents a different risk profile from an accountant, and the price reflects that. Higher limits and riskier trades cost more, while a clean claims record can help.

Because many small businesses buy public liability as part of a combined commercial or tradesman package alongside employers' liability, tools and product liability, the way the policy is assembled affects both price and the breadth of protection. The cheapest standalone option is not always the best fit once contract requirements and exclusions are taken into account.

Regulation, claims and complaints

The insurers and brokers that provide public liability cover must be authorised by the Financial Conduct Authority and follow its Insurance Conduct of Business rules, which require fair treatment, clear information and proper claims handling. A business can confirm a provider's authorisation on the FCA Financial Services Register before buying.

If a claim is made against the business, prompt notification to the insurer is usually a policy condition: delays can prejudice the claim. The insurer typically takes over handling, investigating liability and either defending or settling. Under the Insurance Act 2015, a commercial buyer must make a fair presentation of the risk when arranging cover, so describing the business activities accurately at the outset protects the validity of any later claim.

Where a dispute arises, for example the policyholder disagrees with how their insurer handled a complaint or a claim, the firm's complaints process comes first. Eligible micro-enterprises and small businesses can then escalate to the Financial Ombudsman Service, which considers complaints free of charge. This gives small businesses an independent route to challenge an insurer's decision without going to court.

Frequently asked questions

Is public liability insurance a legal requirement?

For most businesses, no. Unlike employers' liability cover, which is compulsory once you have staff, public liability is generally optional. However, many clients, landlords and contracts require it, so in practice most customer-facing businesses hold it.

What limit of public liability cover do I need?

Common limits are 1 million, 2 million, 5 million and 10 million pounds. The right level depends on your worst-case exposure and on contract requirements, since many public sector and large commercial clients specify a minimum, often 5 million or 10 million pounds.

Does public liability cover my employees?

No. Public liability covers third parties such as customers and the public. Injuries to your own employees are covered by employers' liability insurance, which is a separate and legally required policy for businesses with staff.

What is the difference between public liability and professional indemnity?

Public liability covers physical injury or property damage to third parties. Professional indemnity covers financial loss caused by your advice or professional services. A business that gives advice usually needs professional indemnity, which public liability does not provide.

Will public liability pay if the accident was not my fault?

Public liability responds where the business is legally liable. If the business is not at fault, the insurer may defend the claim rather than pay compensation, but the cover still funds the legal cost of defending it. Liability has to be established for a payout.

Can I challenge my insurer's decision on a public liability claim?

Yes. Use the insurer's complaints process first, and if you are an eligible small business you can then escalate to the Financial Ombudsman Service free of charge. The Ombudsman provides an independent route to review the insurer's decision.
