Public Liability vs Professional Indemnity: Which Cover You Need in 2026, in 5 Questions
Public liability vs professional indemnity insurance for UK freelancers and tradespeople in 2026: what each covers and excludes, which policies are legally required, what clients and professional bodies demand, the real prices insurers publish, the right cover limit, claims-made and run-off, and a five-question test that tells you which to buy.
A joiner fits a kitchen, a cupboard door falls on the client's foot, and the client's solicitor writes a letter. A freelance designer delivers a brochure with the wrong phone number on 10,000 printed copies, and the client wants the reprint paid for. Both are claims; only one of them is covered by public liability insurance. The other needs professional indemnity. Most people who work for themselves find out which is which from the letter, not before it, and the Association of British Insurers' January 2026 survey of 1,002 small firms found 28% of sole traders carry no business insurance at all.
Public liability vs professional indemnity is the question every new freelancer and tradesperson asks, and the honest answer is "it depends what you do, and what your clients demand". This guide gives the two definitions from the insurers' own trade body, the handful of policies the law actually requires, what professional bodies and contracts insist on, the prices insurers publish in 2026, the right cover limit, the claims-made trap, and a five-question test you can answer in two minutes.

The two covers, side by side
| Public liability (PL) | Professional indemnity (PI) | |
|---|---|---|
| What it pays for | Compensation for injury to other people, death, or loss of or damage to their property, caused by your work or your premises | Compensation for financial loss a client or third party suffers because of negligent advice, design, services or errors |
| A claim it covers | A customer trips over your toolbag; your ladder scratches a parked car; a cupboard falls on a client's foot | A wrong survey measurement; a brochure printed with an error; a website that leaks data because of your configuration; advice that loses a client money |
| What it does not cover | Injury to your own staff (that is employers' liability), damage to your own property, claims about your advice, deliberate acts | Injury or property damage (that is PL), deliberate misconduct, work done before the policy's retroactive date, employer duties |
| Who usually needs it | Anyone who works at clients' premises, in public, or has customers visit: trades, cleaners, fitness, events, shops, mobile services | Anyone paid for advice, design, calculation, writing, code or judgement: consultants, designers, developers, architects, accountants, surveyors, marketers |
| Legally required? | No, but often required by clients, venues and councils | No in general, but mandatory for regulated professions and in many contracts |
| Typical limit | £1 million or £2 million; £5 million or £10 million for public-sector contracts | £50,000 to £1 million for most freelancers; more for regulated professions |
The Association of British Insurers (ABI) puts it in one line each: public liability covers "personal injuries, loss of or damage to property and death"; professional indemnity covers claims "because of the impact of negligent services" or advice. If your work could hurt someone or break something, you need the first. If your work could cost someone money by being wrong, you need the second. Many trades need both: a kitchen fitter who also designs the kitchen is giving advice as well as swinging a hammer.
What the law actually requires
Only two business policies are compulsory for most people, and neither is PL or PI.
- Employers' liability insurance the moment you employ anyone, including part-time, casual or temporary staff: at least £5 million of cover under the Employers' Liability (Compulsory Insurance) Regulations, with a fine of up to £2,500 for every day you are not insured and £1,000 for not displaying the certificate, according to GOV.UK. Family-only businesses and sole traders with no staff are exempt.
- Motor insurance at third-party level for any vehicle, including the van.
Public liability is optional in law, and professional indemnity is not a general legal requirement either. The requirement comes from somewhere else: the client, the site, the venue, the landlord, the professional body or the regulator. That is where most freelancers meet it.
Who demands it anyway
- Regulated professions. The Solicitors Regulation Authority requires a minimum of £2 million of PI per claim (£3 million for most firms). The Institute of Chartered Accountants in England and Wales requires at least £2 million, or 2.5 times fee income with a £250,000 floor for smaller firms, under rules in force from 1 October 2026. The Architects Registration Board's guidance sets a £250,000 each-and-every-claim minimum, and an architect who departs from it has to justify why.
- Public-sector and corporate contracts. Councils routinely demand £5 million or £10 million of public liability for contractors; East Sussex County Council's tender requirements, for example, list £10 million as standard. IPSE, the self-employed trade body, says it is common for client contracts to make PI with a minimum limit a mandatory condition.
- Sites, venues and landlords. A building site, a market, a school or a serviced office will usually ask for your PL certificate before you set foot on it.
- Agencies and platforms. Recruiters placing contractors often require PI; trade platforms show insured status to customers.
The practical test is simple: read the last three contracts or terms you signed, and look for the word "indemnity" or "insurance". If it is there, so is the requirement.
What it costs in 2026, from the insurers' own pages
| Cover | Published price | Basis and date |
|---|---|---|
| Public liability, sole trader | £64.37 a year or less | What 10% of Simply Business sole-trader customers paid, January to June 2026 |
| Public liability, self-employed builder | £87.89 a year | Simply Business example quote, page updated September 2026 |
| Public liability | From £5.20 a month | Hiscox, based on 10% of its customers, August 2025 to August 2026 |
| Professional indemnity, consultant | £91 a year or less | What 10% of Simply Business consultant customers paid, January to June 2026 |
| Professional indemnity | £96.60 to £412.62 a year | Simply Business published examples, September 2026 |
| Professional indemnity | From £8.50 a month | Hiscox, same basis as above |
| Professional indemnity, £50,000 limit | From £8 a month | Markel's published starting price |
These are starting prices, not averages: a one-person consultancy with a £100,000 PI limit can pay under £100 a year; a scaffolder's public liability or a surveyor's PI costs many times that. The point is the order of magnitude. A year of public liability costs less than one hour of a solicitor's time.
How much cover: the limit question
- Public liability. Simply Business says 85% of its sole-trader customers choose £1 million and 15% choose £2 million; public-sector contracts may require £5 million or £10 million. Match the highest limit any client has asked for, and remember the limit is per claim.
- Professional indemnity. Limits run from £50,000 to £5 million. Pick the limit from the worst realistic loss a client could suffer from your mistake, not from your fee: a £2,000 brochure job can produce a £20,000 reprint. Regulated professions have their minimums set for them.
- Employers' liability. £5 million is the legal floor; most policies give £10 million.
The claims-made trap, and why you keep paying after you stop
Public liability is normally written on a "claims occurring" basis: if the accident happened while you were insured, you are covered, even if the claim arrives years later. Professional indemnity is normally "claims made": the policy that pays is the one in force when the claim is made, not when the work was done. The ABI's guidance says the insurer will only cover claims brought during the policy term, and recommends run-off cover when you cancel. The Architects Registration Board advises keeping run-off for at least six years after you stop practising (five in Scotland), and the Solicitors Regulation Authority and ICAEW make six-year run-off mandatory. If you do advisory or design work, budget for PI to outlive the business.
The add-ons tradespeople actually use
- Product liability: for things you make, supply or sell, as opposed to services. Not required by law, often required by contract.
- Tools cover: loss, theft or damage to hand and power tools, usually including from the van overnight within limits.
- Contractors all risks: covers the project itself (materials and work in progress) against fire, flood, storm, theft and vandalism, which neither PL nor PI touches.
- Legal expenses, personal accident and income protection: optional, and worth a look once the business pays the mortgage.
The 5-question test
- Could your work physically hurt someone or damage their property? Yes means public liability, at £1 million minimum, £2 million if you work in homes or busy sites.
- Are you paid for advice, design, calculations, writing, code or a judgement a client acts on? Yes means professional indemnity, with the limit set by the worst realistic loss.
- Do you employ anyone, even part-time or casual? Yes means employers' liability at £5 million, by law, from day one.
- Does any contract, site, venue, body or platform you work with name a cover or a limit? Buy exactly that, or more.
- Will you stop trading in the next few years? If you hold PI, plan for run-off.
Two yeses to questions 1 and 2 is the common case for trades who also design or specify, and for consultants who visit sites. Combined policies exist and cost less than two separate ones.

Frequently asked questions
What is the difference between public liability and professional indemnity insurance?
Public liability pays compensation when your work or premises injures someone or damages their property. Professional indemnity pays when a client or third party loses money because your advice, design, service or work was negligent. Trades mostly need the first, advisers and designers the second, and many businesses need both.
Is public liability insurance a legal requirement in the UK?
No. The only compulsory business policies for most people are employers' liability (at least £5 million, as soon as you employ anyone) and motor insurance. Public liability is demanded by clients, sites, venues and councils rather than by law, which in practice makes it essential for anyone working in public or in other people's homes.
Do I need professional indemnity insurance as a freelancer?
If you are paid for advice, design, writing, code, calculations or any judgement a client acts on, yes in practice: IPSE says contracts commonly make PI with a minimum limit a condition, and regulated professions have minimums set by their bodies. A pure labour-only trade usually does not need it.
How much does public liability insurance cost?
Insurers' own pages in 2026 show entry prices well under £100 a year: 10% of Simply Business sole-trader customers paid £64.37 or less for the year to June 2026, and Hiscox quotes from £5.20 a month. Higher-risk trades, higher limits and staff push the price up.
How much professional indemnity cover do I need?
Enough to cover the worst realistic loss a client could suffer from your mistake, and at least whatever your contracts or professional body require. Limits run from £50,000 to £5 million; £100,000 to £1 million covers most freelancers, and ICAEW, the SRA and the ARB set their own minimums.
What does claims-made mean for professional indemnity?
The policy in force when the claim is made is the one that pays, not the one in force when you did the work. That is why PI needs run-off cover after you stop trading: the ARB advises at least six years, and solicitors and accountants are required to keep it.
Can an AI agent help me get the right insurance?
It can read your contracts for the clauses, write the broker brief, compare the quotes and keep the certificates and renewal dates. Create a free Jobbit Pro profile with 300 bonus credits plus 100 a day, add the insured line to your profile, and let the briefed, scoped jobs come to you with payment held in escrow.
