What's Actually Inside a Freelancer's Professional Indemnity Policy (UK 2026)

Most freelancers buy professional indemnity insurance because a client contract demands it — then never read the policy. Here's what's actually inside, which exclusions catch people out, and what "run-off cover" really means.

⚡ 2026 update: The FCA's General Insurance Pricing Practices rules continue to reshape how insurers calculate renewal premiums — meaning your PI renewal quote in 2026 may look very different from last year's. Now is a good time to actually read what you're buying.At a glance

  • Professional indemnity (PI) insurance covers you if a client claims your work caused them a financial loss — but the details vary enormously between policies.
  • Most policies are written on a claims-made basis, meaning the policy active when the claim is made pays out — not the one active when the work was done.
  • Run-off cover is what protects you after you stop trading; without it, claims relating to past work may be uninsured.
  • Common exclusions include deliberate acts, contractual liability beyond common law, and claims arising from work done before the policy's retroactive date.
  • Your limit of indemnity is the maximum the insurer will pay per claim (or in aggregate per year) — check which applies to your policy.
  • Not legal/financial advice: This article explains the rules in plain English. For your specific situation, speak to an insurance broker or Citizens Advice.

A client emails on a Friday afternoon. They say a report you delivered six months ago contained an error, and because of it they've lost a contract worth £50,000. They're looking to you to cover the loss.

This is exactly the scenario professional indemnity insurance is supposed to handle. But whether your policy actually pays out depends entirely on the small print — the stuff most freelancers have never read.

This guide walks through a standard UK professional indemnity policy section by section, in plain English, so you know what you've got before you need it.

What professional indemnity insurance actually covers

Professional indemnity (PI) insurance is designed to protect you if a client suffers a financial loss as a result of your professional advice, service, or work. The core promise is: if a client sues you for negligence, the insurer will cover your legal defence costs and, if you're found liable, pay out the damages — up to the policy limit.

The key word is professional. PI is about the quality of the work and advice you provide in your professional capacity. It is not the same as:

  • Public liability insurance — which covers physical injury or property damage to a third party (e.g. you spill coffee on a client's laptop during a meeting).
  • Employers' liability insurance — legally required if you hire anyone, even on a casual basis.
  • Cyber insurance — which covers data breaches, ransomware, and digital liability.

Many freelancers need all three, but they're separate products. Don't assume one policy covers everything.

Claims-made vs occurrence: the most important clause you've never read

Almost every professional indemnity policy sold in the UK is written on a claims-made basis. This is fundamental and often misunderstood.

Under a claims-made policy, what matters is when the claim is first notified to the insurer — not when the work was done, and not when the error happened. If a client discovers a mistake you made in 2023 and makes a formal claim in 2026, your 2026 policy responds, not your 2023 one.

The practical consequence: if you let your policy lapse — even for a single day — work done while you were insured may be left uncovered. That's why continuous renewal is so important for freelancers, even when work is slow.

What's a retroactive date?

Most claims-made policies include a retroactive date — the earliest point in time for which claims will be accepted. Work done before this date is excluded, even if the claim arrives while the policy is active.

When you buy a new policy, always check the retroactive date. Ideally it should go back to when you first started freelancing in your profession. If a new insurer offers you a cheaper premium but resets the retroactive date to today, you've lost cover for all your historical work.

Run-off cover: the clause that matters when you stop

When you retire, close your business, or change careers, you stop paying for PI insurance. But claims can still arrive years later — and a claims-made policy won't respond if there's no active policy when the claim comes in.

Run-off cover (sometimes called "tail cover") solves this. It's a policy you take out when you stop trading that keeps you covered for a fixed period — typically two, four, or six years — for claims arising from past work.

Run-off cover costs vary, but many insurers offer it at a reduced rate because no new work is being done. The standard recommendation is to maintain at least six years of run-off cover after stopping work, to match most contractual limitation periods.

Limit of indemnity: per claim or in aggregate?

Your policy's limit of indemnity is the most the insurer will pay. But there are two different ways this limit can work, and it matters enormously:

  • Per claim — the limit applies to each individual claim. If you have a £1m per-claim policy and face two separate £800,000 claims in one year, both are (in principle) covered.
  • In aggregate — the limit is the total the insurer will pay across all claims in a policy year. A £1m aggregate policy paying out £600,000 on one claim leaves only £400,000 for everything else that year.

Per-claim limits offer more protection but typically cost more. Read your schedule carefully to see which applies.

How much cover do freelancers actually need?

The right amount depends on the scale of projects you work on and what clients demand. Many freelancers are required by contract to hold a minimum of £1m or £2m. Technology consultants, financial advisers, and those working in regulated sectors often need £5m or more.

A sensible starting point: your limit should be at least as high as the total value of the largest single client project you've ever worked on, multiplied by two.

Struggling to make sense of your own PI policy?

Upload your policy documents to Clarify and ask in plain English: "What does my run-off cover include?" or "Is my retroactive date set to when I started freelancing?" You'll get cited, plain-English answers — no insurance jargon, no broker fees.

Common exclusions — the clauses that catch freelancers out

All PI policies exclude certain things. The exact list varies by insurer, but these are the most common ones freelancers encounter:

Deliberate, dishonest, or fraudulent acts

If you knowingly misled a client or committed fraud, the insurer won't pay. This applies even if the fraud is alleged rather than proven — many policies suspend cover while investigations are ongoing.

Contractual liability beyond common law

If you voluntarily accepted liability in a contract that goes further than what the law would impose on you anyway, that extra liability is often excluded. For example, agreeing to guarantee a specific business outcome (rather than just professional care and skill) can leave you personally exposed.

This is a key reason to have a solicitor or specialist AI review client contracts before you sign — and why you should think carefully before agreeing to "performance warranties".

Work done before the retroactive date

As covered above, any claim arising from work done before the retroactive date is excluded. Always check this date when switching policies.

Intellectual property disputes

Some standard PI policies exclude IP infringement claims — for example, if a client alleges you plagiarised their competitor's work. This matters for writers, designers, and developers. Check whether your policy includes IP cover or whether you need it as an add-on.

Insolvency of the client

If a client goes into administration before settling a dispute, your ability to recover costs — even if you win — may be limited. PI insurance covers your defence and damages, but it won't recover unpaid invoices.

What "defence costs" actually means

One of the most valuable parts of a PI policy is that it covers your legal defence costs — which can be substantial even if a claim is ultimately unsuccessful. The phrase to look for in your policy is whether defence costs are:

  • Included within the limit of indemnity — meaning your defence eats into the maximum payout available. If you spend £80,000 defending a £100,000 claim, only £20,000 remains for any damages.
  • In addition to the limit of indemnity — meaning defence costs are covered on top of your limit. This is better for the policyholder and is now common in many mid-market policies.

When comparing quotes, check this point explicitly. It can make a bigger difference than the headline premium.

What to do if a client threatens a claim

  1. Don't panic — and don't admit liability. Even an informal "sorry, I'll fix it" email can be treated as an admission. Keep communications factual.
  2. Notify your insurer immediately. Most policies require you to notify the insurer as soon as you become aware of a potential claim — not just when a formal claim arrives. Late notification can give the insurer grounds to reduce or refuse cover.
  3. Preserve all evidence. Keep emails, contracts, drafts, and version histories. These will form the backbone of your defence.
  4. Follow the insurer's instructions. Once notified, the insurer will typically appoint solicitors to handle the claim. Don't instruct your own lawyers without checking whether this is allowed under the policy.

Get answers from your policy, not guesswork

Before a claim happens, upload your PI policy to Clarify and ask: "What are my notification obligations?" or "Does this policy cover IP infringement?" Know your policy before you need it.

Frequently asked questions

Do I legally have to have professional indemnity insurance as a freelancer?

In most cases, no — PI insurance is not a statutory requirement for the majority of freelancers in the UK. However, certain regulated professions (such as solicitors, financial advisers, and architects) are legally required to hold it. Beyond that, clients routinely demand a minimum level of cover as a contractual requirement before you can work with them.

Does PI insurance cover mistakes made by subcontractors I hired?

It depends on the policy. Some policies cover work performed by subcontractors on your behalf; others exclude it. If you regularly engage subcontractors, make sure they hold their own PI cover and check whether your policy explicitly includes or excludes their work.

My client's contract says I need £5m of cover, but I only have £1m. What should I do?

Contact your insurer or broker to discuss increasing your limit of indemnity. Temporary increases (sometimes called "project-specific cover") are available from many insurers for large one-off contracts. Don't start work requiring a higher limit of cover until the policy is in place.

What's the difference between "any one claim" and "annual aggregate"?

"Any one claim" means the limit applies separately to each claim you make in a policy year. "Annual aggregate" means the total paid across all claims in that year cannot exceed the limit. If you make multiple claims, an aggregate limit can run out — a per-claim limit resets for each new claim.

Can I get PI insurance if I work through a limited company?

Yes. PI insurance is available to both sole traders and limited companies. If you operate through a limited company, make sure the policy is in the company's name — a personal policy may not respond to claims made against the company as a legal entity.

What is "civil liability" cover and do I need it?

Some PI policies are narrowly written to cover only "professional negligence" — that is, mistakes in your professional work. Broader "civil liability" policies extend cover to other civil wrongs such as defamation, breach of confidentiality, or infringement of intellectual property rights. Whether you need this depends on the nature of your work.

If I take a career break, do I need to keep paying for PI insurance?

If your policy is claims-made (as most are) and you stop paying, claims arising from past work will not be covered while the policy is lapsed. Either maintain your policy at a reduced level during a break, or take out run-off cover for the period you're not actively insured.

How do I find a good broker for freelance PI insurance?

Look for a broker who specialises in your sector — a broker who mainly handles tradespeople may not understand the nuances of technology or creative freelance work. The British Insurance Brokers' Association (BIBA) has a "find a broker" tool on their website. Always compare at least two or three quotes before buying.
