Do I need insurance as a self-employed sole trader?
A plain guide to insurance for self-employed people: what's legally required, what clients will insist on, and what's genuinely optional.
Quick answer
Public liability is not a legal requirement for most sole traders, but it's effectively compulsory in practice — clients, venues and platforms ask for it, and one claim without it can end your business. Employers' liability is legally required the moment you employ anyone. Professional indemnity matters if you give advice. Treatment risk cover matters if you work on people's bodies.
Which insurance, and when
| Cover | Required? | Who needs it |
|---|---|---|
| Public liability | Not by law, but expected | Anyone working in others' homes or spaces |
| Employers' liability | Legally required | Anyone who employs staff, including part-time |
| Professional indemnity | No, often contractual | Coaches, consultants, designers, bookkeepers |
| Treatment / malpractice | No, but essential | Therapists, beauty, massage, PTs |
| Tools & equipment | No | Trades carrying valuable kit |
| Vehicle (business use) | Legally required | Anyone driving for work |
Step-by-step
- 1
Start with public liability
It covers injury to a third party or damage to their property arising from your work. It isn't legally mandatory for most sole traders, but it's the one clients ask about, venues require, and platforms check. Working in someone's home without it is a business-ending risk for a modest annual premium.

Employers' liability the moment you take anyone on
This one genuinely is a legal requirement, and it applies as soon as you employ someone — including part-time, casual and sometimes family members. The penalties for not having it are significant. If you're moving from solo to your first hire, sort this before their first day.
- 3
Professional indemnity if you give advice
Covers claims that your advice or work caused a client financial loss. Relevant for coaches, consultants, bookkeepers, designers and anyone producing work a client relies on. Frequently a contractual requirement in B2B work — check before signing rather than after.

Treatment cover if you work on people
Massage therapists, beauty and aesthetics practitioners, personal trainers and complementary therapists need cover for the treatment itself, not just public liability. Professional body membership often bundles this, which is one of the better reasons to join one.

Put it on your website
Being insured is a genuine differentiator that most self-employed people never mention. A line stating you hold public liability cover, with the amount, converts better than it has any right to — particularly for anyone working unsupervised in a client's home.

Common questions
Do I legally need insurance to be self-employed?
+−
Public liability isn't a legal requirement for most sole traders, though clients and venues routinely insist on it. Employers' liability is legally required as soon as you employ anyone. Business use on your vehicle insurance is required if you drive for work.
What insurance does a sole trader actually need?
+−
Public liability as the baseline for anyone working in others' homes or spaces. Add professional indemnity if you give advice, treatment cover if you work on people's bodies, tools cover if you carry valuable equipment, and employers' liability the moment you hire.
What's the difference between public liability and professional indemnity?
+−
Public liability covers physical injury or property damage caused by your work. Professional indemnity covers financial loss caused by your advice or professional work. A plumber needs the first; a bookkeeper needs the second; a personal trainer arguably needs both plus treatment cover.
Do I need insurance if I work from home?
+−
If clients visit you, yes — public liability applies to your premises too, and home insurance typically excludes business activity. If you never see clients and don't handle their property, the case is weaker, though professional indemnity may still apply if you advise.
