Professional Indemnity Insurance for UK Freelancers
If clients pay you for advice, designs, code, writing or any other professional service, a mistake in that work could cost them money. Professional indemnity insurance is designed to cover claims like that. This explainer covers what it does, when UK freelancers need it, how to pick a level of cover and the policy details that are easy to miss. It is general information, not insurance or legal advice, so read policy documents carefully and speak to a broker if you are unsure.
Key takeaways
- Professional indemnity insurance covers claims that your professional work or advice caused a client a financial loss.
- It is not generally required by law for freelancers, but many clients, agencies and some professional bodies require it.
- Most policies are written on a claims made basis, so the policy in force when the claim is made is the one that responds.
- Choose your limit based on contract requirements and the realistic size of a client loss, not on price alone.
- Read the exclusions, the excess and whether the limit is per claim or in total for the year.
Freelancers tend to think about insurance only when a client asks for a certificate. By then you are rushing to buy something before a contract starts, which is the worst time to compare policies. Understanding the basics in advance helps you buy the right cover once and renew it sensibly each year.
This guide focuses on professional indemnity. Public liability insurance, which deals with injury to people and damage to property, is a separate product that we cover in its own guide.
What professional indemnity insurance covers
Professional indemnity insurance, often shortened to PI, protects you if a client claims that your work, advice or service was negligent, wrong or incomplete and that it cost them money. The policy typically pays the legal costs of defending the claim and any compensation you are required to pay, up to the policy limit.
Exact cover varies by insurer and by policy, but claims PI is designed for commonly include:
- Professional negligence: an error, omission or poor advice that causes the client a loss.
- Breach of confidentiality: accidentally disclosing information the client shared in confidence.
- Intellectual property infringement: unintentionally using material that belongs to someone else.
- Defamation: content you produce that damages someone's reputation.
- Loss of documents or data: client material lost or damaged while in your care.
Some of these may be standard, optional or excluded depending on the policy, so check the wording rather than assuming.
What it usually does not cover
PI is not a catch-all. It typically does not cover injury to people or damage to property (that is public liability), your own equipment, deliberate wrongdoing, contractual promises that go beyond normal professional standards, or claims you knew about before the policy started. Cyber incidents may be partly covered or need a separate cyber policy.
Pro tip
Describe your work precisely when you buy cover. If your policy says "copywriter" but you also give marketing strategy advice or build websites, an insurer may argue that a claim from those activities is outside the policy. Update your business description whenever your services change.
Do UK freelancers need it?
For most freelancers, professional indemnity insurance is not a general legal requirement. Whether you need it depends on three things.
Your clients
Many larger businesses, public sector bodies and recruitment agencies require contractors to hold PI cover at a stated minimum level, and they may ask for a certificate before you start. If a contract requires cover and you do not have it, you can be in breach before any work begins.
Your profession
Some regulated professions and professional bodies require members to hold PI insurance, often with set minimum terms. If you belong to such a body, check its rules, because they override any general guidance.
Your risk
Even when nobody requires it, consider what would happen if a client blamed you for a loss. Advice, technical work, financial or legal content, software, data handling and design that others rely on all carry real potential for costly disputes. Defending a claim can be expensive even when you did nothing wrong.
Example
Imagine a freelance web developer, Sam, who builds an online shop for a small retailer. A bug in the checkout means some orders fail for two weeks before anyone notices. The retailer says it lost sales and wants Sam to pay. Whether Sam is actually liable is unclear, but he still needs legal help to respond. With PI cover that includes his web development work, he notifies his insurer, which deals with the claim under the policy terms.
How claims made cover works
This is the detail that catches people out. Most professional indemnity policies are written on a claims made basis. That means the policy that responds is the one in force when the claim is made against you, not the one in force when you did the work.
In practice this has two consequences:
- You need continuous cover. If you let your policy lapse and a client brings a claim next year about work you did this year, you may have no policy to respond.
- Think about run-off cover when you stop. If you close your business, retire or move into employment, run-off cover can protect you for claims that arrive after you stop trading. Claims can come months or years after the work.
Check the retroactive date too. Some policies only cover work done after a certain date, often when you first bought cover. Keeping continuous cover with an unchanged retroactive date protects your earlier work.
Common mistake
Cancelling PI cover the moment a big contract ends to save money. Because most policies are claims made, a claim about that contract could arrive after the policy has gone. If you are winding down, ask about run-off cover before you cancel.
Choosing the right level of cover
PI policies have a limit of indemnity: the maximum the insurer will pay. Picking that number is a judgment call, and these steps help you make it sensibly.
- Start with contract requirements. Check every current and likely client contract for a minimum PI limit. Your cover needs to meet the highest one you are likely to sign.
- Estimate a realistic worst case. Think about how much a client could lose if your work went wrong. Consider the size of the projects you work on and what depends on them.
- Check per claim or aggregate. Some limits apply to each claim, others to all claims in the policy year combined. Clients sometimes specify which they want.
- Check whether costs are inside the limit. Some policies include legal defence costs within the limit; others pay them in addition. This makes a real difference to how far the limit goes.
- Look at the excess. This is the amount you pay toward each claim. A higher excess may lower your premium but leaves you exposed to more cost.
Premiums depend on your profession, turnover, claims history, the limit you choose and the insurer, so compare like for like. A broker can be useful if your work is specialist or clients set unusual requirements.
What to check in a policy
| Policy feature | Question to ask |
|---|---|
| Business description | Does it cover every service I actually provide? |
| Limit of indemnity | Does it meet my contract requirements? Per claim or aggregate? |
| Defence costs | Are legal costs included in the limit or paid in addition? |
| Excess | How much do I pay toward each claim? |
| Retroactive date | Is my earlier work covered? |
| Territory and jurisdiction | Am I covered for overseas clients or claims brought abroad? |
| Exclusions | Are contractual liabilities, cyber or specific activities excluded? |
| Notification rules | How and how quickly must I report a possible claim? |
Insurance and your contract work together
Your contract and your insurance should support each other. A sensible limitation of liability clause in your contract caps what a client can claim, and your PI cover pays for claims up to its limit. If your contract promises more than your policy covers, or accepts unlimited liability, you could be left with a gap. Check both together whenever a client sends you their own terms.
If something goes wrong
If a client complains about your work or hints at a claim, tell your insurer promptly, following the notification terms in your policy. Avoid admitting liability or offering compensation before talking to the insurer, because that can affect your cover. Keep records of the work, emails and any decisions the client made.
Your PI insurance checklist
- List the PI requirements in your current and likely client contracts
- Write an accurate description of every service you provide
- Decide a limit of indemnity and whether you need per claim or aggregate cover
- Compare excess, defence costs, territory and exclusions, not just price
- Keep cover continuous and note your retroactive date
- Save your certificate where you can send it to clients quickly
- Ask about run-off cover before you stop trading or change structure
Frequently asked questions
Is professional indemnity insurance a legal requirement in the UK?
For most freelancers it is not a general legal requirement. It is often required by clients, agencies or professional bodies, and some regulated professions must hold it. Check your contracts and any membership rules.
What is the difference between professional indemnity and public liability?
Professional indemnity covers financial loss caused by your professional work or advice. Public liability covers injury to people or damage to their property connected with your business. Many freelancers need both, and some insurers sell them together.
Does my policy cover work for clients outside the UK?
Not always. Policies set territorial and jurisdiction limits, and claims brought in some countries may be excluded. If you have overseas clients, check this before you buy and tell the insurer where your clients are.
Is professional indemnity insurance a business expense?
Insurance taken out wholly and exclusively for your business is generally an allowable expense for sole traders. Check HMRC guidance or ask an accountant how it applies to your situation.

The bottom line
Professional indemnity insurance protects you against the cost of a client blaming your work for a financial loss. Most freelancers are not legally required to have it, but many clients will ask for it, and the cost of defending even an unfounded claim can be serious. Describe your services accurately, choose a limit that fits your contracts, keep cover continuous and read the exclusions.
This is general information, not insurance or legal advice. Policy terms differ widely between insurers, so read the full policy wording and speak to a broker or adviser if your work carries particular risks.
