Is Public Liability Insurance a Legal Requirement in the UK?

Editorial review: 28 June 2026

Public liability insurance is not a universal legal requirement for every UK business. Many businesses buy it voluntarily or because a client, tender, venue, landlord or licence requires evidence of cover.

The correct question is therefore not only “Is it required by law?” It is:

1. does a statute, regulation or licence condition apply to this activity;
2. does a regulator, trade scheme or membership rule apply;
3. does a contract, tender, lease, venue or permit require it;
4. if none of those applies, does the business still choose it to manage third-party injury and property-damage risk?

Quick answer: For most ordinary businesses, public liability insurance is optional in the sense that no general statute compels every business to buy it. That does not mean it is optional under a particular contract or licence, or that operating without it carries no financial risk.

Start with the Public Liability Insurance UK guide for the wider cover and claims framework.

The general UK position

Government business guidance identifies employers’ liability and motor insurance as the main broadly applicable legal requirements. It describes public liability separately as cover businesses may need where they work with the public or where a venue or client requires it in a contract.

The ABI likewise states that employers’ liability is legally required for employers, while other liability types are generally optional. That is a useful general rule, but it should not be turned into the absolute statement that public liability can never be legally required.

Specific legislation and licensing regimes can require public liability insurance for particular activities.

Statutory and licensing requirements

Hiring out horses

In England, businesses hiring out horses for riding require a local-authority licence. Schedule 5 of the Animal Welfare (Licensing of Activities Involving Animals) (England) Regulations 2018 requires the licence holder to hold a valid public liability insurance certificate covering specified injury and death liabilities connected with hiring the horse.

GOV.UK guidance also states that a riding establishment in England needs public liability insurance to cover injuries to or caused by people hiring horses.

For Wales and Scotland, GOV.UK licensing guidance says a riding establishment needs liability insurance covering injuries resulting from people riding its horses. The applicable legal framework and council conditions should be checked in the relevant nation.

Animals kept or trained for exhibition in England

Schedule 7 of the 2018 England Regulations requires a licence holder to hold valid public liability insurance for the licensable activity of keeping or training animals for exhibition.

These examples demonstrate why the legal question must be answered by activity and jurisdiction. They are not a complete list of every specialist licence, statutory scheme or regulated activity that may involve insurance.

Employers’ liability is a different requirement

A business with employees may need employers’ liability insurance. GOV.UK states that it must generally be obtained when a business becomes an employer, subject to defined exceptions, and must provide at least £5 million of cover from an authorised insurer.

Employers’ liability concerns injury or illness suffered by employees through work. Public liability concerns third parties such as customers, visitors and members of the public. Buying public liability does not satisfy an employers’ liability obligation.

Motor insurance is different too

A business using vehicles must consider the motor-insurance requirements that apply to those vehicles and their use. Public liability commonly excludes liabilities that must be insured under compulsory motor law.

A public liability certificate should not be presented as evidence that the business has the correct motor or employers’ liability cover.

Contractual requirements

A client may require public liability insurance as a condition of appointment. This is common in:

• construction and maintenance contracts;
• facilities-management and cleaning work;
• public-sector and large-company procurement;
• event, exhibition and entertainment work;
• supplier onboarding;
• consultancy assignments involving site visits;
• concessions, franchises and market stalls;
• work involving vulnerable people or public access.

The contract may specify:

• a minimum limit, such as £2 million, £5 million or £10 million;
• the activities that must be covered;
• the territorial scope;
• how long evidence must remain valid;
• whether products liability is also required;
• whether subcontractors need equivalent insurance;
• whether the client must be noted or indemnified in a particular way;
• a deadline for providing a certificate.

A contractual limit is not automatically a recommendation of adequate cover. It is a minimum term set by that counterparty. The policy still needs to match the actual work and liabilities.

Tender requirements

A tender questionnaire may ask for the insurer, policy number, expiry date and limit. It may make a particular limit a pass-or-fail condition.

Before confirming compliance, check:

• whether the limit applies to each occurrence or in total;
• whether the tender requires products liability as well as public liability;
• whether the declared business activities include the tendered work;
• whether relevant exclusions conflict with the contract;
• whether the policy territory and jurisdiction match the project;
• whether the business can maintain cover throughout the contract.

Do not state that a policy “fully complies” merely because the certificate shows the requested headline limit.

Venues, event organisers and landowners

A venue or landowner may require insurance before allowing an event, class, stall, performance, filming activity or contractor onto the site. The requirement may appear in:

• hire terms;
• a permit or licence;
• event-supplier conditions;
• market rules;
• a risk-assessment process;
• a lease or concession agreement.

The venue may require its own name to appear on evidence or ask for a particular indemnity. Any request to amend the policy should be referred to the insurer or broker rather than improvised on a certificate.

Local-authority requirements

Local authorities can act in different capacities: regulator, licensor, venue operator, landowner, contracting authority or event organiser. A council requirement may therefore arise from law, a licensing condition or a contract.

Ask for the precise basis of the requirement and the exact insurance wording. Do not assume that every council in every nation uses the same limit or conditions.

Trade bodies and membership schemes

A trade body, accreditation scheme, platform or franchise may require public liability cover even when no statute does. The rule may protect customers, support complaints arrangements or create a minimum entry standard.

Check whether the requirement is mandatory for membership, recommended only, or limited to particular categories of work.

Working from home

There is no general rule that every home-based business must buy public liability insurance. Exposure changes when customers, suppliers, students or other visitors attend the home.

The ABI suggests considering public liability where people visit a home for professional purposes. The household insurer, landlord or mortgage provider may also require notification of business use. Public liability does not automatically amend or replace home insurance.

Sole traders and limited companies

The legal form does not decide whether public liability insurance is compulsory. A sole trader and a limited company can each face contractual, licensing and third-party liability exposures.

A limited company may separate company liabilities from personal assets in many circumstances, but it does not make claims disappear or guarantee that no individual will ever be named. Insurance should be assessed by activity, parties, contracts and legal duties.

What happens if a required policy is missing?

The consequence depends on why the insurance was required.

Statutory or licence requirement

The business may be unable to obtain or retain the licence, may face enforcement or may be unable lawfully to carry on the activity.

Contract or tender requirement

The business may fail the tender, be refused site access, breach the contract, lose payment rights or face termination and indemnity issues.

Voluntary risk decision

There may be no insurance to fund the defence and covered compensation if a claim arises. The business could have to meet legal and settlement costs from its own resources.

Insurance does not cap legal liability merely because the policy limit is lower than the claim.

Evidence of insurance

A certificate or schedule can show that a policy exists and state a limit and dates. Use Understanding Business Insurance Documents to distinguish the certificate, schedule, wording and endorsements. A certificate does not necessarily show:

• every exclusion and endorsement;
• whether the activity is correctly declared;
• whether products liability is included;
• whether defence costs reduce the limit;
• whether a special contract clause is covered;
• whether the insured has complied with conditions;
• whether the policy will respond to a particular incident.

Provide genuine insurer-issued evidence. Do not alter a certificate or describe cover more broadly than the documents support.

No compulsory policy does not mean no legal duty

A business can owe duties to visitors, customers, neighbours and other third parties even when no law requires it to buy public liability insurance. The legal duty and the insurance requirement are separate questions.

For example, a premises occupier may have duties to lawful visitors, and a supplier may face liability connected with a defective product. If no insurance applies, the business may still have to defend the allegation and pay any liability from its own resources.

The absence of a compulsory-insurance rule should therefore never be described as permission to ignore health and safety, product safety, occupiers’ duties, licensing conditions or contractual obligations.

Questions to put to the person requiring insurance

Where a client, venue or authority asks for public liability insurance, obtain the requirement in writing and clarify:

• the exact insured name and contracting entity;
• the required limit and whether it is any one occurrence or aggregate;
• whether products liability is included;
• the required territory and jurisdiction;
• whether subcontractors need separate evidence;
• whether any principal must receive an indemnity or be noted;
• the period for which evidence must remain current;
• whether special activities or event dates must be stated;
• what happens if the policy renews during the contract.

Refer unusual wording to the insurer or broker. A business should not promise an extension, waiver or indemnity that the insurer has not agreed.

Four-step requirement check

Step 1: identify the activity and jurisdiction

List every material activity and where it is carried out. Search the current licensing and regulatory rules for that activity in England, Wales, Scotland or Northern Ireland as applicable.

Step 2: read contracts and permissions

Check client contracts, tenders, leases, venue terms, permits, platform rules and membership conditions.

Step 3: compare the requirement with the policy

Match the insured name, activities, limit, products cover, territory, dates, excess and exclusions. A requested certificate is the end of the check, not the start. Record the result in the Business Insurance Review Checklist so the evidence can be revisited at renewal.

Step 4: assess voluntary exposure

Even where there is no mandatory rule, consider who could be injured, what property could be damaged and whether the business could fund an uninsured defence and award.

Practical next step

Create a practical requirement register with four clear columns: source of requirement, exact wording, evidence needed and renewal date. Keep legal and contractual requirements separate so that the business can prove why each policy and limit is maintained.
