No contract, however well-drafted, can fully shield you from the cost of a professional negligence claim. If a client suffers financial loss because of your advice or work — even if you believe the claim is unjust — defending it costs money. Professional indemnity insurance covers that risk. This guide explains what it is, who needs it, and how to choose a policy.
What Professional Indemnity Insurance Covers
Professional indemnity (PI) insurance — called "errors and omissions" (E&O) insurance in the US — covers claims made against you for:
- Professional negligence: Your work didn't meet the required standard and caused loss
- Errors and omissions: You made a mistake or left something out that caused financial harm
- Bad advice: A client followed your recommendation and lost money as a result
- Intellectual property infringement: Your work inadvertently infringed a third party's copyright or trademark
- Breach of confidentiality: You accidentally disclosed confidential information
- Defamation: Content you created was found to be defamatory
Crucially, PI insurance covers your legal defence costs even if the claim against you is ultimately unsuccessful. Legal fees for defending a professional negligence claim can run to tens of thousands of pounds or dollars even when you win.
What PI Insurance Doesn't Cover
Standard PI policies do not cover:
- Intentional wrongdoing or fraud
- Criminal acts
- Bodily injury or property damage (public liability insurance covers this)
- Employment disputes (employers' liability or employment practices liability insurance covers this)
- Claims arising from work done before the policy's retroactive date
Which Freelancers Need PI Insurance?
Any freelancer who provides advice, expertise, or a professional service that a client could claim caused them financial loss should seriously consider PI insurance. High-risk categories include:
- Consultants and advisors: Business, IT, marketing, HR, financial consultants
- Web designers and developers: A website bug, security vulnerability, or missed deadline could cause significant client losses
- Copywriters and content creators: IP infringement, inaccurate content, or defamation claims
- Graphic designers: IP infringement, brand damage from design errors
- Architects and engineers: Often legally required to hold PI insurance
- Accountants and bookkeepers: Errors in financial advice or reporting
Some professions are legally required to hold PI insurance as a condition of practice (solicitors, financial advisers, architects, chartered accountants). Check your professional body's requirements.
How Much Coverage Do You Need?
Coverage limits depend on the scale and nature of your work:
- £100,000/$100,000: Suitable for freelancers doing small-scale work with individual clients
- £500,000/$500,000: Appropriate for most professional freelancers working with SMEs
- £1-2 million: Required by many larger corporate clients and public sector bodies
- £5 million+: Required for high-risk professional work or major contracts
Check what your clients require — many corporate clients specify a minimum PI coverage level in their contracts. If you're applying for a public sector contract, £1-2 million is typically the minimum.
How Much Does PI Insurance Cost?
Typical annual premiums for freelancers in the UK:
- £100,000 coverage: £80-£200/year
- £500,000 coverage: £150-£400/year
- £1 million coverage: £200-£600/year
- £2 million coverage: £300-£1,000+/year
Premiums vary by profession (higher-risk professions pay more), annual revenue, nature of clients, and claims history. Compare quotes from specialist freelance insurers such as Hiscox, Simply Business, and Kingsbridge.
PI vs Public Liability: Do You Need Both?
PI insurance and public liability (PL) insurance cover different risks:
- PI: Financial loss caused by your professional services or advice
- PL: Physical injury to people or damage to property caused by your activities
If you work entirely remotely and never visit client premises or have clients visit you, PI alone may be sufficient. If you work on-site, attend client offices, or have meetings in person, both PI and PL are recommended. Many insurers offer combined packages.
What to Check When Buying PI Insurance
- Claims-made vs occurrence basis: PI policies are typically claims-made — the policy active when the claim is made covers it, not the policy active when the work was done. Keep coverage active even after you finish with a client.
- Retroactive date: Check whether prior work is covered. Some policies cover claims arising from work done before the policy start date (retroactive cover).
- Run-off cover: If you stop working, you may need run-off cover for claims that arise after you've cancelled your policy.
- Policy exclusions: Read what's excluded — some policies exclude specific industries or types of work.
Protect Your Work With a Professional Contract
A strong contract works alongside PI insurance to minimise your liability exposure.

What does professional indemnity insurance cover?
PI insurance covers claims for professional negligence, errors, omissions, bad advice, IP infringement, and breach of confidentiality that caused a client financial loss. It covers legal defence costs plus compensation — even in claims you ultimately win.
Which freelancers need professional indemnity insurance?
Any freelancer giving advice or providing a professional service that could cause financial loss should consider PI insurance: consultants, developers, designers, copywriters, accountants. Some professions (solicitors, financial advisers, architects) are legally required to hold it.
How much does professional indemnity insurance cost for a freelancer?
PI insurance for freelancers typically starts at £80-£200/year for £100,000 coverage. Higher limits (£1-2 million) cost £200-£1,000+/year. Premiums vary by profession, revenue, and nature of work. Compare quotes from multiple providers.
What is the difference between professional indemnity and public liability insurance?
PI insurance covers financial loss from professional services or advice. Public liability covers physical injury or property damage. Freelancers who work on-site or meet clients in person should consider both.
Does a freelance contract replace the need for PI insurance?
No. A contract can limit liability but cannot eliminate it. PI insurance covers situations where you are legally liable despite contract terms and funds your legal defence even when you win. Contract protection and PI insurance are complementary, not interchangeable.
