Do sole traders need insurance?
Quick Answer / Executive Summary
Not by default. A UK sole trader with no employees has almost no compulsory business insurance, apart from motor insurance for any vehicle and, in a few regulated professions, cover set by the regulator. Employers liability becomes mandatory the moment you employ someone. Everything else, including public liability and professional indemnity, is voluntary but often demanded by clients. The full breakdown is in our sole trader insurance guide.
Key Takeaways at a Glance
- The law makes very little compulsory for a one-person business: employers liability once you hire, and motor insurance for vehicles you drive.
- Some regulated professions must hold professional indemnity under their regulator's rules, for example solicitors and architects.
- Clients, landlords, councils and venues are the real source of most insurance requirements, usually through contract clauses.
- A sole trader has unlimited personal liability, so voluntary cover protects your savings and home, not just the business.
- Work out what you need with what insurance do I need as a sole trader rather than buying a package you do not use.
What the Law Actually Requires
Two requirements commonly apply to sole traders:
• Employers liability, under the Employers' Liability (Compulsory Insurance) Act 1969, as soon as you employ someone. The minimum is £5 million, and GOV.UK says fines can reach £2,500 for every day you are not properly insured. Details: do sole traders need employers liability insurance.
• Motor insurance for any vehicle you drive, with the right use class if you drive for work; see business car insurance for sole traders.
If you work alone, have no staff and do not drive for the business, UK law requires no business insurance at all.

Where Requirements Come From in Practice
Most sole traders end up insured because someone else asks. Supplier forms, main contractors, landlords, event organisers and professional bodies commonly require public liability (£1m to £5m is typical) or professional indemnity. Some regulators also set minimum cover for their members. These are contractual or professional rules, not general law, but you cannot work without meeting them.
Why Voluntary Cover Matters More for You
A limited company is a separate legal person. A sole trader is not, so a court judgment against the business is a judgment against you, payable from personal savings and, in the worst case, your home. That is why advisers treat public liability and, where relevant, professional indemnity as sensible even when nobody compels you. Compare the position in sole trader vs limited company insurance.
When You Genuinely May Not Need Cover Yet
If you are testing a side project with no clients on site, no advice-giving and no employees, you can reasonably delay some policies. Check first with do I need insurance for a side hustle. Do not delay motor use cover, and do not ignore your home insurer: tell them if you are running a business from home (working from home insurance). Think also about income, since the self-employed get no statutory sick pay; income protection for the self-employed covers that gap.
Is It Worth the Cost?
Public liability for a low-risk sole trader can cost £50 to £65 a year, and around £106 to £140 a year for £1m to £5m of cover in 2026. Business policies are generally an allowable expense for tax, as explained in is business insurance tax deductible for sole traders. Set that against the cost of defending even one weak claim yourself.
Real-Life Case Incident & Precedent
Precedent: No statute requires professional indemnity for copywriters. The obligation arose from contract law: once signed, the insurance clause bound Hannah to hold and evidence the cover.
The Copywriter and the Supplier Form
Scenario: Hannah is a self-employed copywriter working from home with no insurance. A new corporate client sends a supplier agreement requiring £250,000 of professional indemnity cover in force before the first invoice is paid.
Resolution & Judicial Outcome: She buys a professional indemnity policy online the same day, sends the certificate, and the contract proceeds. No law required it, but the contract did. Her policy also gave her a route to defence costs if the client later disputed her work.

What You Should Do: Step-by-Step Action Plan
1
Confirm whether you employ anyone or drive for work. Those two facts trigger the only compulsory covers.
2
Read the insurance clauses in any contract or booking terms you are about to sign.
3
Use what insurance do I need as a sole trader to match cover to how you actually work.
5
Diary an annual review, since cover needs change as you take on staff or larger clients.
Critical Mistakes to Avoid
- Assuming no law means no risk. Your personal assets are the business's assets.
- Hiring casual help without checking employers liability duties.
- Ignoring contract insurance clauses until the day before a job starts.
- Relying on a home or car policy that excludes business use.
