Public liability insurance (PLI) protects your business against claims from third parties — members of the public, customers, suppliers, or other non-employees — who suffer injury or property damage as a result of your business activities. The policy covers the cost of legal defence, compensation, and related expenses.
Unlike employers’ liability insurance, public liability is not a legal requirement in the UK. However, it is considered essential for most businesses and is often required by clients, landlords, and event organisers as a condition of working together.
What Does Public Liability Insurance Cover?
PLI covers claims arising from your business activities where a third party suffers:
Bodily Injury
- A customer slipping on a wet floor in your shop
- A visitor tripping over equipment at your premises
- A member of the public being struck by materials falling from a scaffolding site
- A client being injured during a service you are providing
Property Damage
- Accidentally damaging a client’s property while working on their premises
- Spilling materials or chemicals that damage someone else’s belongings
- A fire or flood originating from your premises affecting neighbouring properties
- Dropping equipment that damages flooring, furniture, or fittings
Associated Costs
The policy covers:
- Compensation awarded to the claimant
- Legal defence costs, including solicitors, barristers, and expert witnesses
- Court costs if the case goes to trial
- Medical expenses for the injured party (in some policies)
What PLI Does Not Cover
- Injuries to your employees — This requires employers’ liability insurance
- Professional negligence — Covered by professional indemnity insurance
- Product defects — Covered by product liability insurance (though some PLI policies include basic product liability)
- Motor vehicle incidents — Covered by motor insurance
- Deliberate acts — Intentional damage or injury is excluded
- Contractual liability — Some policies exclude liability you have specifically assumed under contract
Who Needs Public Liability Insurance?
While not legally compulsory, PLI is effectively essential for:
- Any business with premises that customers or visitors can access (shops, restaurants, offices, salons)
- Tradespeople and contractors — Plumbers, electricians, builders, decorators, and other trades working on client premises
- Event organisers — Running events with public attendance
- Market stall holders and pop-up shops — Landlords and market organisers invariably require PLI
- Consultants visiting client sites — Even desk-based professionals who visit client premises
- Delivery businesses — Drivers entering customer premises
Contractual Requirements
Many organisations require you to hold PLI before they will do business with you:
- Local authorities require PLI for contractors and service providers
- Large corporate clients often set minimum PLI levels in their procurement requirements
- Landlords may require PLI as a condition of your commercial lease
- Industry bodies and trade associations may make PLI a condition of membership
How Much Cover Do You Need?
Public liability insurance is available with limits of indemnity ranging from £1 million to £10 million or more. The right level depends on:
| Factor | Consideration |
|---|---|
| Nature of your work | High-risk activities (construction, events) need higher limits |
| Client requirements | Many contracts specify minimum levels (commonly £2 million or £5 million) |
| Premises | Businesses with public-facing premises may need higher cover |
| Scale of operations | Larger operations with more public contact need higher limits |
For most small businesses, £1 million to £2 million is a common starting point. Tradespeople and contractors are typically asked for £2 million to £5 million, and businesses working on larger commercial or public-sector contracts may need £5 million to £10 million.
How Much Does PLI Cost?
| Factor | Impact on Premium |
|---|---|
| Industry | Higher-risk sectors pay more (construction > office-based consulting) |
| Turnover | Higher turnover generally means higher premiums |
| Cover limit | Higher limits of indemnity cost more |
| Claims history | Previous claims increase premiums |
| Number of employees | More staff interacting with the public increases risk |
| Location | Some areas have higher claim frequencies |
For a small, low-risk business, premiums can start from as little as £40 to £80 per year. Higher-risk businesses or those needing larger limits may pay £200 to £1,000+ per year.
PLI is commonly sold as part of a business insurance package that also includes employers’ liability and other covers, which is often more cost-effective than buying policies separately.
Making a Claim
If an incident occurs that might lead to a claim:
- Record the details — Note what happened, when, where, who was involved, and any witnesses
- Take photographs — Document the scene, any damage, and the conditions
- Notify your insurer promptly — Most policies require you to report incidents within a set timeframe
- Do not admit liability — Let your insurer investigate and respond
- Preserve evidence — Keep any relevant documents, CCTV footage, or correspondence
- Cooperate with the insurer — Provide all requested information and access
Reducing Your Risk
Good risk management reduces both the likelihood of claims and your insurance premiums:
- Carry out regular risk assessments — Identify hazards and take steps to eliminate or reduce them
- Maintain your premises — Keep floors clean and dry, repair hazards promptly, ensure adequate lighting
- Use signage — Warn of wet floors, uneven surfaces, restricted areas
- Train your staff — Ensure everyone understands their responsibilities for safety
- Keep records — Document risk assessments, maintenance, training, and incidents
- Review regularly — Update your risk assessments when circumstances change
PLI on the Balance Sheet
Public liability insurance premiums are an allowable business expense for tax purposes, reducing your taxable profit. The cost appears in the profit and loss account as part of your operating expenses.
Maintaining proper accounting records of insurance costs helps at tax time and when renewing your policy. You can find more about how expenses and liabilities are recorded in our guide to the balance sheet.
Public Liability vs Other Insurance Types
| Insurance Type | What It Covers |
|---|---|
| Public liability | Third-party injury or property damage from business activities |
| Employers’ liability | Employee injury or illness from work |
| Professional indemnity | Financial loss from professional negligence |
| Product liability | Injury or damage caused by products you sell or supply |
| Key person insurance | Financial impact of losing a critical individual |
Most businesses need multiple types of insurance working together. If you have employees, employers’ liability is a legal requirement, and if you provide professional advice, professional indemnity is strongly recommended alongside PLI.
Choosing a Policy
- Assess your risks — What activities does your business carry out that could cause injury or damage to third parties?
- Check contract requirements — What level of cover do your clients, landlords, or industry bodies require?
- Compare providers — Use a broker or comparison tool to get multiple quotes
- Read the policy wording — Understand the exclusions and conditions
- Review annually — As your business changes, your insurance needs change too
