If you run a business in the UK — whether self-employed, freelance, or managing a team — you’ve probably heard about public liability insurance and professional indemnity insurance.
They both protect you from costly claims, but they cover very different types of risks.
Understanding the difference can help you choose the right cover — and avoid paying for the wrong one.
What Is Public Liability Insurance?
Public Liability Insurance (PLI) protects your business if someone from the public — like a customer, supplier, or visitor — is injured or their property is damaged because of your work.
It covers the cost of compensation, repairs, and legal fees if someone makes a claim against you.
Example:
-
A customer slips on a wet floor in your café and breaks their arm.
-
A tradesperson accidentally damages a client’s wall while working.
In both cases, public liability insurance pays for the claim costs and protects your business financially.
What Is Professional Indemnity Insurance?
Professional Indemnity Insurance (PI) covers you if a client claims that your advice, service, or work caused them financial loss or reputational damage.
It’s particularly important for businesses that offer professional advice or design services — like consultants, accountants, architects, or marketing agencies.
Example:
-
A web designer accidentally deletes a client’s website.
-
A financial advisor gives incorrect advice leading to client losses.
-
An architect makes a design error that causes extra construction costs.
Professional indemnity insurance covers legal defence costs, compensation, and settlements.
Key Differences Between Public Liability and Professional Indemnity
| Feature | Public Liability Insurance | Professional Indemnity Insurance |
|---|---|---|
| Who It Protects | Public, customers, visitors | Clients who rely on your advice or service |
| Type of Risk Covered | Physical injury or property damage | Financial loss from advice, mistakes, or negligence |
| Typical Users | Shops, cafés, tradespeople, event organisers | Consultants, designers, accountants, IT professionals |
| Example Claim | Customer trips over a cable | Client loses money due to your mistake |
| Legal Requirement | Not legally required but often needed by contracts | Required by many professional bodies and clients |
Do I Need Both Types of Insurance?
In many cases, yes — especially if you:
-
Work with the public and provide professional services or advice
-
Run a consultancy, design, or trade-based business
-
Work on client sites or offer specialist advice
For example:
A construction consultant visiting a client’s site might accidentally damage property (public liability issue) and also give incorrect advice that causes delays (professional indemnity issue).
Having both types ensures you’re fully covered from physical and professional risks.
When You Might Only Need Public Liability Insurance
You might only need public liability insurance if:
-
You have a shop, café, salon, or trades business
-
You interact physically with the public
-
You don’t provide specialist advice or professional services
Examples:
-
Hairdresser
-
Plumber
-
Electrician
-
Event organiser
When You Might Only Need Professional Indemnity Insurance
You might only need professional indemnity insurance if:
-
You work mainly with clients who rely on your advice
-
You don’t have in-person interactions with the public
Examples:
-
Accountant
-
Consultant
-
Graphic designer
-
Software developer
-
Copywriter
Typical Costs in the UK
The cost depends on your business type and cover level.
| Insurance Type | Average Annual Cost | Typical Cover Amount |
|---|---|---|
| Public Liability | £70–£300 | £1–£5 million |
| Professional Indemnity | £100–£500 | £250k–£2 million |
You can often get a discount by combining both policies with the same insurer.

Final Thoughts
Public liability and professional indemnity insurance may sound similar, but they protect you from completely different situations.
-
Public Liability = Protects against physical injury or damage.
-
Professional Indemnity = Protects against mistakes or bad advice.
If your business deals with the public and provides expert services, having both is the safest and smartest choice.
Insurance isn’t just a formality — it’s your business’s shield against unexpected claims and financial loss.
