Is Public Liability Insurance Mandatory

Public liability insurance is not legally required, but in many industries it is essential. Learn who needs it and when it becomes necessary.

Is Public Liability Insurance Mandatory?

Public liability insurance is one of the most common types of business insurance in the UK. It protects you if a member of the public makes a claim against your business for injury or damage to property. Whether you’re a self-employed tradesperson, a shop owner, or an events organiser, you’ve probably been told you need it. But is public liability insurance mandatory?

The short answer is: not legally, in most cases. However, there are many situations where public liability insurance becomes effectively essential. In this guide, we explain when it is required, who needs it, and why skipping it could be a costly mistake.

What Is Public Liability Insurance?

Public liability insurance covers claims made by members of the public for:

  • Accidental injury

  • Accidental damage to property

  • Legal fees and compensation costs

It applies to situations where your business interacts with the public, such as clients visiting your premises, working on someone else’s property, or dealing with customers in public spaces.

For example:

  • A customer trips over your equipment and breaks their wrist

  • You scratch a client's car while unloading tools

  • A member of the public is injured by falling signage outside your shop

In each case, public liability insurance would help cover the costs of legal defence, settlement or compensation.

Is Public Liability Insurance Legally Required?

In most industries and situations, public liability insurance is not required by law. You will not be fined by the government or HMRC for not having it, and there is no central body enforcing its use.

However, it becomes effectively mandatory in many practical scenarios. You may be required to hold it if:

  • You want to work with local authorities or public sector bodies

  • You are bidding for contracts or tenders

  • You need access to certain construction sites

  • You are joining a trade association

  • You are renting a market stall or exhibition space

  • A client or agency insists on it in their contract

In these cases, you may be turned down for work, lose out on opportunities, or be denied access if you cannot show a valid insurance certificate.

Who Should Have Public Liability Insurance?

Although not legally required, public liability insurance is strongly recommended if your work involves:

  • Dealing with clients or customers face to face

  • Visiting or working on other people’s property

  • Running a shop, café or public venue

  • Attending markets, fairs, or public events

  • Operating in trades such as plumbing, building, decorating, or gardening

Even home-based businesses may need it if clients visit your property or if you work on-site elsewhere.

Sole traders, limited companies, freelancers and partnerships are all eligible to take out cover.

When Is Insurance Legally Required?

There are some forms of business insurance that are legally required, including:

  • Employers' liability insurance: If you employ anyone, even part-time or casually, this is a legal requirement. Minimum cover of £5 million is required.

  • Motor insurance for business vehicles: If you use a car or van for work, it must be insured for business use.

Public liability insurance is not on this list, but depending on your industry, it may be viewed as a professional standard.

What Happens If You Don’t Have It?

If you do not have public liability insurance and a claim is made against you, you will have to cover all legal costs, compensation, and damages yourself. This can run into thousands of pounds or more, depending on the severity of the incident.

For many small businesses and self-employed professionals, an unexpected claim without insurance could lead to serious financial hardship or even the closure of the business.

Additionally, you may find it harder to secure clients, work on large projects, or compete for tenders if you cannot provide proof of insurance.

How Much Cover Do You Need?

The amount of cover you need depends on your industry and client requirements. Standard cover levels include:

  • £1 million

  • £2 million

  • £5 million

  • £10 million (often required for public sector contracts)

Some clients or contracts may specify a minimum amount, so always check before you take out a policy.

Final Thoughts

Public liability insurance is not a legal requirement in the UK, but in many sectors it is essential to operate professionally and safely. It protects your business financially, gives clients peace of mind, and may be required for access to certain jobs or venues.

If your business has any interaction with the public, customers, or clients, having public liability insurance is a sensible and often necessary precaution. While you may not be breaking the law by going without it, you could be taking a serious financial risk.
