Do I Need Public Liability Insurance?

At Towerstone Accountants we provide specialist limited company accountancy services for directors and owner managed businesses across the UK. We created this webpage for business owners who want clear guidance on business and personal insurance, including what cover may be required, how policies are taxed, and how insurance costs impact a company. Our aim is to help you understand your options, manage risk sensibly, and avoid unnecessary expense or compliance issues.

This is one of the most common questions I hear from people starting a business or reviewing their costs. It usually comes with a follow up such as my business is small, I work from home, or I rarely see customers. In my experience the confusion comes from mixing up what is legally required with what is sensible and commercially necessary.

Public liability insurance sits in an awkward space. For most businesses it is not a strict legal requirement yet operating without it can expose you to risks that far outweigh the cost of the cover. Whether you need it depends on how your business operates, who you interact with, and what could realistically go wrong.

In this article I want to explain clearly what public liability insurance is, when you need it, when you might not, and why many businesses choose to take it out even when the law does not force them to. I will also cover the situations where not having it can prevent you from working altogether and the common misunderstandings I see time and again.

What public liability insurance actually covers

Public liability insurance protects your business if a member of the public suffers injury or property damage as a result of your business activities.

This could include situations where

• A customer slips and is injured on your premises
• You damage a client’s property while carrying out work
• Equipment you use causes injury to someone else
• Your business activity creates a hazard that leads to a claim

The insurance usually covers compensation claims and the legal costs involved in defending those claims.

It applies to people who are not your employees. Employees are covered under a different type of insurance.

What public liability insurance does not cover

It is just as important to understand what public liability insurance does not cover.

It usually does not cover

• Injury to employees
• Poor quality work or mistakes in advice
• Professional negligence
• Deliberate acts or misconduct

Other types of insurance such as employer’s liability insurance or professional indemnity insurance cover these risks.

Is public liability insurance legally required

For most UK businesses public liability insurance is not legally mandatory.

There is no general law that says every business must have public liability insurance. You can legally trade without it in many industries.

This is where a lot of confusion arises. People hear insurance discussed alongside legal obligations and assume it is compulsory in all cases. It usually is not.

However legal requirement is only one part of the picture.

Situations where public liability insurance is required

There are circumstances where public liability insurance becomes effectively mandatory.

This can include

• Certain regulated activities
• Work carried out under specific licences
• Industry rules or professional bodies

In these cases the requirement usually comes from a regulator or governing body rather than general business law.

You should always check whether your industry has specific rules.

Employer’s liability insurance is different

One of the most common misunderstandings is confusing public liability insurance with employer’s liability insurance.

Employer’s liability insurance

• Is legally required in most cases
• Applies if you employ staff
• Covers injury or illness suffered by employees

Public liability insurance

• Is usually not legally required
• Covers injury or damage to members of the public

If you have employees you almost certainly need employer’s liability insurance regardless of whether you need public liability insurance.

Why many businesses need public liability insurance in practice

Even though public liability insurance is not usually required by law many businesses still need it in practice.

This is because other organisations often require it as a condition of working with them.

Common examples include

• Local authorities
• Councils and housing associations
• Commercial landlords
• Event organisers
• Large corporate clients
• Schools and public venues

If you want to work on their premises or take on contracts they may insist on seeing proof of public liability insurance.

Without it you may not be allowed to work.

Public liability insurance and client contracts

Many client contracts include clauses that require public liability insurance.

These clauses may specify

• Minimum cover levels
• The duration of cover
• Evidence of insurance before work starts

If you sign a contract that requires insurance and you do not have it you may be in breach of contract even though the law does not require it.

That breach can expose you to serious financial risk.

Working on other people’s property

If your business involves working on other people’s property public liability insurance becomes particularly important.

Examples include

• Tradespeople
• Cleaners
• IT engineers visiting offices
• Gardeners
• Maintenance services

Accidental damage is more common than people expect and claims can arise even when you believe you were not at fault.

Do sole traders need public liability insurance

Sole traders often ask whether public liability insurance matters if they are small or just starting out.

In my experience sole traders are often more exposed than limited companies.

As a sole trader

• You are personally liable for claims
• There is no separate legal entity to absorb losses
• Your personal assets may be at risk

A single claim could affect your home savings or future income.

For many sole traders public liability insurance is not just sensible, it is essential.

Do limited companies need public liability insurance

Limited companies benefit from limited liability but that does not mean insurance is unnecessary.

If a company faces a claim

• The company’s assets are at risk
• The business may be unable to continue trading
• Reputation damage may occur

Insurance provides practical protection that complements the legal structure.

Limited liability does not stop claims. It only affects who ultimately bears the cost.

Businesses with high exposure to public risk

Some businesses face higher risk simply because of how they operate.

These often include

• Retail businesses with customer footfall
• Construction and trades
• Fitness instructors and personal trainers
• Event based businesses
• Child related activities
• Hospitality and food service

In these sectors operating without public liability insurance is rarely realistic.

Businesses with lower exposure

Some businesses have lower interaction with the public.

Examples might include

• Home based consultants
• Remote online services
• Software developers working from home

Even here risk is not zero. Clients may still visit your premises or claim that your actions caused loss or damage.

Lower risk does not mean no risk.

What happens if you do not have public liability insurance

If you do not have public liability insurance and a claim is made

• You must handle the claim yourself
• You must pay legal fees yourself
• Any compensation awarded must be paid by you or your business

Legal costs alone can be significant even if you successfully defend the claim.

I have seen cases where the cost of legal advice exceeded the value of the claim itself.

The role of health and safety enforcement

Claims often arise alongside health and safety issues.

Investigations may involve bodies such as the Health and Safety Executive.

Insurance does not stop investigations but it often provides access to legal support and guidance during the process.

How much cover do you usually need

There is no single correct level of cover.

Common levels include

• £1 million
• £2 million
• £5 million
• £10 million

The right level depends on

• The type of work you do
• Client requirements
• Contract terms
• Potential severity of claims

Many councils and public bodies require at least £5 million of cover.

How much does public liability insurance cost

Cost is often the reason people hesitate.

In practice for many small businesses

• Premiums are relatively modest
• Annual costs may be a few hundred pounds
• Costs vary by industry and risk

When compared to the potential cost of a claim the premium is often small.

Public liability insurance as a business expense

Public liability insurance premiums are usually an allowable business expense.

This means

• The cost reduces taxable profit
• The net cost after tax is lower

This does not make it free but it reduces the real cost.

Public liability insurance and peace of mind

Beyond compliance and contracts there is a psychological benefit.

Insurance allows you to

• Focus on running your business
• Take on work with confidence
• Avoid constant worry about what might go wrong

In my experience business owners who are properly insured make better decisions because they are not operating from fear.

Public liability insurance versus professional indemnity insurance

These two are often confused.

Public liability insurance covers

• Physical injury
• Property damage

Professional indemnity insurance covers

• Financial loss caused by advice or services
• Errors or omissions
• Negligent professional work

Some businesses need one. Some need both. Understanding the difference matters.

Situations where public liability insurance is strongly expected

Even where not legally required some industries treat public liability insurance as standard.

These include

• Construction and trades
• Events and entertainment
• Education and training
• Sports and leisure
• Hospitality

Trying to operate without it often limits opportunities.

What clients usually ask for

When clients ask for proof of insurance they usually want

• An insurance certificate
• Confirmation of cover level
• Dates showing the policy is current

Not being able to provide this can delay work or lose contracts.

Common misconceptions I see

Over the years I see the same misunderstandings repeatedly.

These include

• Thinking public liability insurance is always legally required
• Assuming small businesses do not need it
• Believing limited liability removes the need
• Confusing it with employer’s liability insurance
• Thinking it only matters if something goes wrong

Understanding these points helps you make an informed decision rather than guessing.

Public liability insurance and risk management

Insurance is only one part of managing risk.

Businesses should also

• Follow health and safety guidance
• Maintain safe premises
• Use equipment properly
• Train staff where relevant

Insurance supports good practice but does not replace it.

What happens if you misdescribe your business

Insurance policies rely on accurate information.

If you

• Understate your activities
• Take on work outside your policy scope

The insurer may refuse to pay a claim.

It is important to review cover when your business changes.

Startups and new businesses

New businesses often delay insurance to save money.

In my experience this is a false economy.

New businesses often

• Have less cash buffer
• Are more vulnerable to claims
• Have less experience managing risk

Early cover provides stability while the business finds its feet.

Reviewing your need for public liability insurance

You should review whether you need public liability insurance when

• You start trading
• You change the type of work you do
• You take on new clients
• You work in new locations

Needs change over time.

The role of HMRC

HM Revenue and Customs does not require public liability insurance as part of tax compliance.

However HMRC expects businesses to operate responsibly and insurance costs are usually allowable.

So do you need public liability insurance

The honest answer is it depends but for most businesses the practical answer is yes.

You may not need it because the law forces you to buy it. You may need it because

• Clients require it
• Landlords require it
• Your work involves risk
• You cannot afford the consequences of a claim

The absence of a legal requirement does not remove exposure.

Final thoughts from experience

In my experience the better question is not do I need public liability insurance but what would happen if I did not have it and something went wrong.

For many businesses the answer is uncomfortable.

Public liability insurance is not about expecting accidents. It is about recognising that accidents happen and protecting the business when they do.

Understanding your risk your client expectations and your financial exposure allows you to make a calm informed decision rather than relying on assumptions.
