Professional indemnity insurance — usually shortened to PI — is the single most important cover for UK freelancers who give advice or produce deliverables for clients. If a client claims your work caused them financial loss, PI is what pays the defence costs and any settlement. This guide covers the cover itself: what's in, what's out, how to size it, how to read the policy, what to do if a claim arises.

What PI actually covers

UK professional indemnity covers civil claims arising from your professional services where the claimant alleges your work, advice, design, or deliverable was negligent and caused them financial loss.

The standard policy heads typically include:

• Defence costs — legal fees defending the claim, regardless of outcome (subject to insurer consent on solicitors)
• Settlement / damages — sums you become legally liable to pay the claimant
• Court awards — judgments against you
• Mitigation costs — reasonable steps to prevent or reduce a claim once notified
• Loss of documents — replacement of client documents you've lost or damaged
• Dishonesty of employees — third-party losses caused by dishonest acts of staff (if you have any)

The cover is "claims made" — the policy in force when the claim is notified to the insurer is the policy that responds, not the policy in force when the work was done. This makes continuous cover critical, and is why run-off cover (continuing PI after you stop trading) matters.

Real claim examples

Anonymised representative examples of the kinds of claims UK freelance PI policies handle:

Web developer, e-commerce site

Freelance developer delivers a custom e-commerce site for a £25k fee. Three months post-launch, a payment-flow bug causes failed orders worth approximately £12k. Client demands repair, refund of fee, plus the lost order value. Claim total ~£35k. PI pays defence costs and a negotiated settlement after expert-witness review of the bug.

Brand designer, IP infringement

Freelance designer creates a logo that turns out to closely resemble a registered trademark. Client receives a cease-and-desist and a £15k IP-damage demand. Designer is contractually liable to indemnify the client. PI covers defence and the negotiated settlement.

Management consultant, strategy advice

Consultant recommends an investment in a new product line based on market analysis. Two years on, the line is unprofitable and the client claims the consultant's analysis was negligent. £180k claim. PI pays for forensic review of the consultant's methodology, defends successfully, but defence costs alone are £35k.

Accountant, missed deadline

Bookkeeper misses a VAT return deadline for a client; HMRC issues £1,800 in penalties and interest. Client demands the accountant cover the cost. Below most policies' excess, but if the accountant carries multiple similar mistakes the aggregate triggers cover.

Copywriter, defamation

Freelance journalist's article contains a factual error that a third party alleges is defamatory. £40k claim plus legal costs. PI policies with libel/slander extension cover; without that extension, may be excluded.

Common exclusions

PI is a defined-perils policy — it covers professional negligence claims, not everything that could go wrong with your business. Standard UK PI exclusions include:

• Deliberate or fraudulent acts — if you knowingly did wrong, no cover
• Criminal acts — fines and penalties from regulatory breach are typically excluded (the underlying defence may still be covered subject to terms)
• Bodily injury / property damage — handled by PL, not PI
• Contractual penalties — liquidated damages clauses that aren't tied to negligence (e.g. simple late-delivery fees) are usually excluded
• Insolvency — claims arising from your own insolvency are excluded
• Asbestos / pollution / war / terrorism — standard market exclusions
• Work outside your declared profession — if you do web design and start giving tax advice, the tax advice claim isn't covered unless declared
• Prior known circumstances — any situation you were aware of before the policy started that could give rise to a claim
• Acts of sub-contractors — unless declared at policy inception

Some exclusions can be removed for additional premium — e.g. libel/slander extension for journalists and copywriters, sub-contractor extension for freelancers who occasionally sub-out work.

Choosing your cover level

The right PI cover is the larger of:

• What your client contracts require
• What your realistic worst-case claim could be
• Any professional body or regulatory minimum (some industries)

Common levels for UK freelancers:

Most clients won't ask for proof of cover for sub-£10k engagements. Above that, expect requests for a certificate showing PI limit and PL limit.

Aggregate vs each-and-every. Most UK PI policies are written on an aggregate basis — the limit is the total across all claims in a policy year. A £250k aggregate policy with three claims totalling £270k has hit the limit. Each-and-every limits exist but are more expensive and less common at freelance scale.

What PI costs

Typical UK freelance PI premiums for £250k aggregate cover (illustrative — get actual quotes):

• Copywriter / VA / coach — £140–£220/year
• Designer / illustrator — £150–£250/year
• Web developer — £200–£350/year
• Marketing consultant — £180–£300/year
• Management consultant — £220–£400/year
• Bookkeeper / accountant — £280–£500/year
• IT contractor — £200–£380/year

Premium variables: industry, cover level, declared revenue, claims history, territorial scope (UK only is cheapest; worldwide ex-US/Canada moderately more; including US/Canada significantly more).

How to read a PI policy

UK PI policy documents typically contain five sections worth reading carefully:

1. Schedule

The personalised front sheet showing: insured name, period of cover, limit of indemnity (aggregate or each-and-every), excess (the amount you pay before insurer pays), declared turnover, declared services. Read these carefully — if your work has changed since you bought the policy, the cover may not respond.

2. Insuring clause

The core promise: what triggers cover. Standard wording is "any claim first made against the insured during the period of insurance arising from any negligent act, error or omission in the conduct of the insured's professional business."

3. Extensions

Additional cover heads — typical extensions include defence costs, mitigation costs, loss of documents, court attendance, public relations costs, employee dishonesty.

4. Exclusions

What's not covered. Read all of them. The most claim-relevant exclusions to check: prior known circumstances, deliberate acts, contractual penalties, sub-contractors, declared activities.

5. Conditions

What you must do to maintain cover. The big one: notification. Most policies require notification of any circumstance that could give rise to a claim, not just formal claims. Failure to notify on time can void cover entirely.

If a claim arises

What to do if you become aware of a possible claim:

1. Notify your insurer immediately — same day if possible. Use the notification line on your policy schedule. Include: what happened, when, who the client is, what they're alleging, any documents.
2. Do not admit liability — verbally or in writing. Don't apologise in writing for the substance of the claim (procedural sorry-you-feel-this-way is usually fine; "I'm sorry I made a mistake" is not).
3. Do not negotiate or settle — without insurer involvement. Doing so can void cover.
4. Preserve all documents — emails, contract, briefs, deliverables, file history. Do not "tidy up" your records after a claim notification.
5. Use insurer-approved solicitors — your insurer will appoint or approve a panel firm. Using your own solicitor without consent typically means the insurer won't pay the bill.
6. Tell the truth on the notification — non-disclosure or misrepresentation can void the policy retrospectively under the Insurance Act 2015.

UK PI providers

The UK freelance PI market has four meaningful options at SME / freelance scale:

• Hiscox — specialist insurer, direct sale. Established freelance and SME presence. Tailored by industry.
• Markel Direct — contractor-focused specialist, particularly strong for IT contractors and consultants.
• Simply Business — comparison broker. Quotes from multiple insurers (Aviva, Zurich, AXA, Hiscox, etc.) via one journey.
• PolicyBee — specialist professional-cover broker, often strong for niche or unusual freelance categories.

Optional extensions worth considering

Standard PI is a defined-perils policy, but most UK insurers offer extensions for an additional premium. The ones worth considering carefully:

Sub-contractor cover

If you ever sub out work — even occasionally to a trusted freelancer collaborator — PI cover doesn't automatically extend to their negligence. A sub-contractor extension covers you as the contracting party if your sub-contractor's work generates a claim. Typically adds 10–20% to premium; essential if sub-contracting is part of your model.

Libel and slander

For journalists, content writers, reviewers, and anyone publishing opinion or factual content, libel/slander extension covers defamation claims. Often a default add-on for content-producing freelancers; without it the standard PI usually excludes these claims.

Intellectual property infringement

Specifically for unintentional IP infringement (you genuinely didn't know a design or content resembled existing IP). Most policies cover this within base PI; some require explicit extension. Worth checking your schedule.

Court attendance compensation

Pays a daily allowance if you have to attend court, mediation, or arbitration as a witness in a claim against you. Modest cost; useful for the time you'll spend on it.

Loss of fees

Some policies extend to your own loss of fees if you have to spend significant time on a covered claim. Not universal — check policy wording.

Worldwide / US-Canada extension

If you work with North American clients, default UK/EU territorial cover doesn't extend to US/Canada jurisdictions. The US extension typically increases premium by 30–80% but is essential if you have meaningful North American client exposure — US litigation costs alone can exceed total claim values for European jurisdictions.

PI market cycles

Like all insurance markets, UK PI has cyclical pricing. Premiums tend to rise after periods of high claims experience and fall when underwriting capacity is plentiful. The freelance / SME segment has been broadly stable over the past several years but is sensitive to:

• Major sector claims events (large data breaches, prominent IT delivery failures)
• Insurance Act / regulatory changes
• Capacity withdrawal at the Lloyd's / reinsurance end of the market

Practical implication: at renewal, even if your own claims record is clean, premium movement isn't fully in your control. Shopping the market every 2–3 years is healthy practice; sticking with a single insurer for 5+ years without quote benchmarking sometimes leaves money on the table.
