Business Insurance for UK Freelancers: What You Need and What the Law Requires (2026)

Most UK freelancers only think about insurance when a contract lands with a clause saying "the Supplier shall maintain professional indemnity insurance of not less than £1,000,000". Then it becomes urgent, and confusing: which cover is that, is it the law, and what else should you have?

This guide sets out the main types of business insurance a UK freelancer comes across, which one is actually a legal requirement, which ones clients ask for, and what to check before you buy.

Short answer: For most UK freelancers with no employees, no business insurance is legally required. Employers' liability becomes compulsory once you employ someone. Professional indemnity and public liability are optional in law, but contracts very often make them a condition of the work.

This is general information, not insurance or legal advice. FreelanceSphere is not an insurance broker.

Professional indemnity: the one clients ask for

Professional indemnity insurance covers you if a client says your work or advice was negligent and it cost them money. Typical situations include:

• a bug in code you delivered that takes a client's shop offline;
• a design that unintentionally uses someone else's copyrighted material;
• advice that turns out to be wrong and leads to a financial loss;
• a missed deadline that causes the client a measurable loss;
• an accidental breach of confidentiality.

The policy pays for your legal defence and any compensation, up to the limit. Without it, a single claim could run to more than a year's income, and if you trade as a sole trader your personal assets are exposed.

Is it compulsory?

Not for most freelancers. The exception is regulated professions, where the regulator makes PI a condition of practising: solicitors, accountants in public practice, surveyors and financial advisers, among others. If you belong to one, your professional body sets the minimum.

For everyone else, the requirement usually comes from the contract. Agencies, recruitment firms and larger clients commonly ask contractors for PI, and many will not let you start without a certificate.

How much cover?

Read the contract. It normally states the minimum limit, and £1 million is a common figure in UK freelance and IT contracts, with some clients asking for £2 million or more. Look closely at the wording:

• "Each and every claim" means the full limit is available for every separate claim.
• "In the aggregate" means the limit is the total for the whole policy year, however many claims there are.

Some contracts also ask you to keep the cover in place for a number of years after the work ends, often six, because a claim can be made long after a project finishes.

Claims-made: why you cannot just cancel it

PI policies are written on a claims-made basis. The policy that responds is the one in force when the claim is made, not when the work was done. So:

• If you cancel your policy and a past client claims next year, you are not covered.
• If you stop freelancing, you may need run-off cover to protect the work you have already done.
• Check the retroactive date on any new policy. Work done before that date is not covered.

Public liability: if you meet people or visit sites

Public liability covers claims from members of the public, including clients, for injury or property damage caused by your business. A client trips over your laptop cable in their office; you knock a monitor off a desk at their premises; a visitor slips at your home office.

It is not a legal requirement, but it is often asked for when you work on a client's premises, attend events, or run workshops. A fully remote freelancer who never meets clients in person is the least likely to need it, although some contracts ask for it regardless.

Employers' liability: the only legal requirement

According to GOV.UK, you must take out employers' liability insurance as soon as you become an employer. The rules are:

• The policy must cover you for at least £5 million, from an authorised insurer.
• You can be fined £2,500 for every day you are not properly insured.
• You must display the certificate where employees can see it (a website or intranet counts), or face a £1,000 fine.

GOV.UK lists two exemptions: if you only employ close family members, or only employ people based outside England, Scotland and Wales. The Health and Safety Executive's guidance also exempts a limited company whose only employee owns 50% or more of the shares, which covers most one-person limited companies where the director is the sole employee.

Freelancers and contractors you hire may or may not count as employees for this purpose, because it depends on their employment status. GOV.UK has a separate checker for who counts as an employee.

If you are a sole trader or a one-person limited company with no staff, you almost certainly do not need EL. The moment you take on an assistant or a junior, you do.

The covers people forget

Equipment. Standard home insurance often excludes or limits cover for equipment used for business. If your laptop is how you earn, check your home policy or add business equipment cover.

Cyber. If you hold client data, a breach brings costs that PI may not cover: notifying people, restoring systems, dealing with the regulator.

Legal expenses and tax investigation. Covers the professional fees of an HMRC enquiry or a contract dispute. Popular with limited company contractors.

What business insurance costs

Premiums depend on your profession, turnover, the limit you choose, your claims history and the excess you accept. A developer, a copywriter and a management consultant pay very different amounts for the same £1 million limit, because the size of the losses they could cause is different. The only reliable way to know is to get quotes for your own activities.

Two things apply to everyone:

• Insurance Premium Tax at the standard rate of 12% is added to the premium.
• Business insurance is an allowable expense. Sole traders deduct it from profits on their Self Assessment, and limited companies from their Corporation Tax profits.

Where to buy

• Direct from an insurer. Several specialist insurers quote freelancers and contractors online in a few minutes. Hiscox is one well-known example, selling PI, public liability, employers' liability and cyber cover direct.
• Through a broker. Useful if your work is unusual or the contract asks for something specific. GOV.UK points to the British Insurance Brokers' Association to find one.
• Through a membership body. Some freelancer and professional bodies bundle insurance into membership. Check exactly what is included and the limits before relying on it.

Whichever you choose, check the firm on the FCA register before you pay.

Before you buy: a checklist

1. Read every live contract for the cover types, minimum limits and how long cover must last after the work ends.
2. Describe your work accurately. A policy written for the wrong business activity may not pay out.
3. Check the limit basis: each and every claim, or aggregate.
4. Check the excess you pay on each claim.
5. Check the retroactive date and whether earlier work is covered.
6. Check territorial limits if you have overseas clients.
7. Keep the certificate somewhere you can send it to a new client in minutes.
8. Diarise the renewal. Many policies renew automatically, and that is the moment to check the premium and the cover still fit.

Where insurance fits in your setup

Insurance is one step in setting up properly. Our freelance business setup checklist puts it alongside registering with HMRC and opening a business bank account. Insurance clauses are also worth reading carefully when you negotiate rates and contracts, and a clear contract is your first defence against the disputes covered in what to do when a client doesn't pay.

If you work through platforms, read our comparison of Upwork vs YunoJuno, since a platform's terms decide who carries the risk if something goes wrong.

Frequently asked questions

Do freelancers legally need insurance in the UK?

Usually not. The only cover the law requires of most businesses is employers' liability, and that only applies once you employ someone. Regulated professions such as solicitors and accountants in public practice must hold professional indemnity under their regulator's rules.

Do I need professional indemnity insurance as a sole trader?

The law does not require it, but your clients may. Many agencies and larger clients make PI a contract condition, commonly at £1 million. As a sole trader you are personally liable for claims, so PI also protects your own assets.

Does a one-person limited company need employers' liability insurance?

Usually not. HSE guidance exempts a company whose only employee owns 50% or more of the shares, which covers most single-director companies. Once you employ anyone else, it becomes compulsory, with a minimum of £5 million cover.

What is the difference between professional indemnity and public liability?

Professional indemnity covers financial loss caused by your work or advice, such as a costly mistake. Public liability covers physical harm: injury to a person or damage to their property.

Can I claim business insurance as an expense?

Yes. Premiums for business insurance are an allowable expense for sole traders and limited companies.

What happens to my professional indemnity cover if I stop freelancing?

PI is claims-made, so once the policy ends, claims about your past work are not covered. Many insurers offer run-off cover for this, and some contracts require cover to continue for several years after the work finishes.
