Public Liability Insurance

Do I Need Public Liability Insurance?

Fact Checked

Public liability insurance isn’t a legal requirement in the UK, but you almost certainly need it if your business interacts with the public, clients, or other people’s property. Councils, landlords, venues, and private clients routinely refuse to work with uninsured businesses, so the practical need is closer to mandatory than the law suggests.

The quick test: if a member of the public could be injured by your work, or their property damaged, you need cover. Without it, any claim comes straight out of your pocket, including legal fees, settlements, and court costs.

This guide walks through who needs cover, when it becomes contractually obligated, what happens if you skip it, whether home-based workers are exempt, and how much you should expect to pay.

Key Takeaway

Public liability insurance isn’t legally required in the UK, but councils, landlords, venues, and platforms like Checkatrade usually won’t work with you without it. A single uninsured claim can easily run past £100,000 once legal fees and compensation are in.

Check public liability insurance prices against the cover level your contracts require.

What is public liability insurance?

Public liability insurance pays out if a member of the public is injured or their property damaged because of your business activities. It covers legal defence costs, compensation, and associated expenses up to your policy limit.

What it covers

The policy responds to third-party injury or property damage caused by your business operations, premises, or products.

Examples include a customer slipping on a wet shop floor, a tradesperson cracking a client’s window with a ladder, or a delegate tripping over a stand at an event. For a full breakdown of inclusions, see our explainer on what PLI actually covers.

What it doesn’t cover

Public liability won’t touch injuries to your own employees, poor workmanship, or professional advice that turns out badly.

For staff injuries you need employers’ liability, and for bad-advice claims you need professional indemnity cover instead.


Who typically needs public liability insurance?

Anyone whose work brings them into contact with the public or their property needs public liability cover, from sole-trader tradespeople up to multi-site businesses.

Common industries and roles

Sector Typical cover level Why it’s needed
Tradespeople (plumbers, electricians, builders) £2m–£5m On-site property damage and injury risk
Mobile therapists and beauticians £1m–£2m Treatment-related injury claims at clients’ homes
Retailers and café owners £2m–£5m Slip, trip, and product-related claims
Event organisers and stallholders £5m–£10m Crowd injury and venue-required minimums
Freelance consultants with client meetings £1m Damage to client property during visits

Mobile trades and lower-risk professions often settle on £2 million public liability cover as the middle ground between affordability and contract acceptance.

Sole traders and the self-employed

Being a one-person business doesn’t reduce the exposure, and if anything a sole trader pays a claim personally rather than from business reserves.

Our guide on whether sole traders need PLI breaks down the scenarios where cover becomes non-negotiable.

Businesses that usually don’t need it

Purely online businesses with no client visits, no product shipments, and no physical premises can often skip public liability cover.

That list is narrower than it sounds, and a single client site visit, pop-up stall, or product demo pulls you back into the need-it category.


Public liability is never legally required in the UK, but it’s routinely contractually required by councils, landlords, venues, marketplaces, and larger commercial clients.

The legal position

Only employers’ liability insurance is compulsory by law. If you employ anyone, the Employers’ Liability (Compulsory Insurance) Act 1969 requires at least £5m of employers’ liability cover, enforced by the HSE.

The HSE’s guidance on employers’ liability confirms public liability is separate and voluntary, though strongly recommended for most trading businesses.

When contracts demand it

Typical situations where proof of cover is required:

  • Local authority contracts (often a minimum of £5m).
  • Shopping centres and market halls (£5m+ for stallholders).
  • Event venues, halls, and festival organisers (£5m to £10m).
  • Commercial landlords requiring tenants to insure activities.
  • Referral platforms such as Checkatrade or Bark.

The most common contract threshold is £5 million public liability cover, which is what councils, larger events, and commercial landlords typically specify.

Employers’ vs public liability

The two are often confused but cover different people. Our comparison of employers’ liability and public liability lays out which one handles which claim type.


What happens if I don’t have public liability insurance?

Without public liability cover, you pay every legal and compensation cost yourself. A single serious claim can run into tens of thousands of pounds and bankrupt a small business.

The financial exposure

Legal defence alone typically costs £5,000 to £15,000 before any compensation is awarded. Add a serious injury payout and the total can exceed £100,000.

Sole traders carry unlimited personal liability, so the claim can come after personal savings, property, and future earnings, not just the business.

Reputational fallout

Uninsured status tends to surface during a claim, and word travels fast through trade bodies, referral platforms, and review sites.

Rehiring from councils, landlords, and marketplaces becomes materially harder once you’ve been flagged as a non-compliance risk.

Lost contracts and listings

Most platform marketplaces suspend accounts the moment a valid certificate lapses, and councils can remove approved-contractor status without notice.

Getting back on an approved-supplier list afterwards often takes longer than simply keeping cover in place.


Do I need public liability insurance if I work from home?

Yes, if you host clients at home, visit other people’s premises, or handle their property, you still need public liability cover. Home office workers with zero client contact are the exception, not the rule.

Clients visiting your home

The moment a client steps over the threshold, they become a third party on your business premises in insurance terms.

A trip down the hallway or spilled coffee on a client’s laptop is enough to trigger a claim that your home insurance almost certainly excludes.

Visiting client premises

Freelancers, consultants, photographers, and tradespeople who work at client sites carry the same exposure whether their business address is commercial or a spare bedroom. Cover typically starts around £1m for low-risk professions.

Why home insurance doesn’t help

Standard home insurance excludes business activities, so any client-related claim is usually rejected.

Some insurers offer a business-use extension, but it’s narrower than standalone public liability and often won’t meet contract minimums.


How much does public liability insurance cost?

Most UK small businesses pay between £60 and £300 per year for public liability cover, depending on trade, turnover, location, and required cover level.

Typical cost by profession

Business type £1m cover £5m cover £10m cover
Graphic designer / low-risk freelancer £60 £80 £110
Mobile beautician £90 £130 £170
Plumber (sole trader) £120 £180 £240
Electrician (sole trader) £140 £210 £280
Event organiser (small-medium) £200 £320 £420

These are illustrative annual premiums for standalone cover, and the exact figure moves with turnover and claims history. See our full breakdown of what PLI costs across different trades for more detail.

What drives your premium

Insurers weight the quote on trade risk, turnover, number of staff, locations worked at, claims history, and the cover level you pick.

Higher-risk trades such as roofers, tree surgeons, and anyone using heat or hazardous materials typically sit at the top of the range.

Is it tax deductible?

Yes, premiums are treated as an allowable business expense by HMRC so they reduce taxable profits, and the gov.uk guide to self-employed expenses confirms the rules for sole traders and partnerships.

Frequently Asked Questions (FAQs)

Can I get public liability insurance for just one event?

Short-term cover runs from a single day to a few weeks and is commonly used for fairs, exhibitions, market stalls, and one-off gigs.

Is public liability insurance tax deductible?

In most cases yes, because HMRC treats premiums as an allowable business expense for sole traders and limited companies.

Does public liability insurance cover subcontractors?

Not always: many policies exclude subcontractors unless they’re declared, so check the wording and either add them or make sure they carry their own cover.

What happens if I’m uninsured and someone makes a claim?

You personally pay every legal, court, and compensation cost, and for a sole trader that liability extends to personal assets rather than just business reserves.

Do online-only businesses need public liability insurance?

Usually not, unless your work involves physical contact such as product demos, site visits, or photography sessions where a client could be injured or their property damaged.

Does public liability insurance cover faulty workmanship?

No: it covers injury and property damage to third parties, not poor workmanship or professional advice, so you’d need professional indemnity insurance for that.

Can I get cover without being a limited company?

Yes, because sole traders and partnerships are eligible on the same basis as limited companies, and business structure doesn’t affect your right to take out cover.

Is it mandatory for market stallholders?

Often yes, because although it’s not a legal requirement, most markets, festivals, and public venues require proof of cover (usually £5m) before they’ll let you trade.

How much cover do I need?

£1m suits low-risk freelancers, £2m to £5m fits most trades, and £10m is the norm for council contracts, events, and high-value commercial work.

Does public liability insurance cover injuries to my own staff?

No, because injuries to employees are handled by employers’ liability insurance, which is a separate and legally compulsory policy if you have any staff.
