What Is Public Liability Insurance?
Public liability insurance protects a business or individual against claims made by third parties — members of the public, clients, or other contractors — who suffer injury or property damage as a result of the insured's work or activities. If a claim is made against you, the policy covers legal defence costs and any compensation awarded, up to the policy limit.
For tradespeople and contractors, public liability insurance is one of the most fundamental covers to have in place. Working in clients' homes and on construction sites creates daily exposure to third-party risks: a slip hazard left on a staircase, a tool dropped from height, or damage to a client's property during the course of work.
Key point: Public liability insurance is not a legal requirement in the UK for most trades, but it is widely required by clients, contractors, and trade bodies as a condition of engagement. Many local authorities and housing associations will not allow uninsured tradespeople onto their properties.
Why Tradesmen Need It
The nature of trade work creates a range of third-party liability exposures that are difficult to eliminate entirely. Even experienced, careful tradespeople can face claims arising from:
- A client tripping over tools or materials left on site
- Accidental damage to a client's property during the course of work (e.g., breaking a pipe, cracking a tile)
- A third party being injured by falling materials or equipment
- Damage to neighbouring properties caused by vibration, dust, or water ingress
- A client claiming that completed work caused subsequent damage to their property
Without public liability insurance, a tradesperson would need to fund legal defence costs and any compensation from their own resources. Claims can be substantial — particularly where personal injury is involved — and can easily exceed the financial capacity of a sole trader or small business.
What Does It Cover?
A standard public liability policy for tradesmen covers claims arising from:
| Type of Claim | What the Policy Covers |
|---|---|
| Third-party bodily injury | Compensation for injury or death suffered by a member of the public, client, or other contractor as a result of your work |
| Third-party property damage | Compensation for damage to a client's or third party's property caused during the course of your work |
| Legal defence costs | Solicitors' fees and court costs incurred in defending a claim, even if the claim is ultimately unsuccessful |
| Products liability | Claims arising from products you have supplied or installed (often included as standard in tradesman policies) |
Most tradesman public liability policies also include completed operations cover — protection against claims arising from work that has already been completed. This is important because defects in workmanship may not become apparent until weeks or months after the job is finished.
What public liability does not cover: Your own injury or illness (this requires personal accident or income protection insurance), damage to your own tools or equipment (this requires tools cover), and liability to your employees (this requires employers liability insurance).
How Much Cover Do You Need?
Public liability insurance for tradesmen is available at various indemnity limits. The most common levels are £1 million, £2 million, £5 million, and £10 million. The appropriate level depends on the nature and scale of your work, and the requirements of your clients and contracts.
| Indemnity Limit | Typical Use Case |
|---|---|
| £1 million | Sole traders doing small domestic jobs with limited exposure |
| £2 million | Standard for most domestic and light commercial tradespeople |
| £5 million | Required by many commercial clients, housing associations, and local authorities |
| £10 million | Required for larger commercial contracts, government work, and high-risk trades |
It is important to check the requirements of any contracts you are tendering for before arranging cover. Arranging a higher limit than strictly necessary is generally preferable to finding that your cover is insufficient after a claim has been made.
Which Trades Does It Cover?
Public liability insurance is available for a wide range of trades and contracting activities. Specialist tradesman policies are available for:
- Builders and general contractors
- Electricians and electrical contractors
- Plumbers and heating engineers
- Roofers and roofing contractors
- Painters and decorators
- Carpenters and joiners
- Plasterers
- Tilers
- Groundworkers
- Scaffolders
- Locksmiths
- Window fitters and glaziers
The premium for public liability insurance varies by trade, reflecting the different risk profiles involved. High-risk trades — such as roofing, scaffolding, and demolition — typically attract higher premiums than lower-risk activities.

Employers Liability: A Legal Requirement
If you employ anyone — including part-time workers, temporary staff, or labour-only subcontractors — you are legally required to hold employers liability insurance under the Employers' Liability (Compulsory Insurance) Act 1969. The minimum statutory limit is £5 million, though most policies provide £10 million as standard.
Failure to hold valid employers liability insurance when required is a criminal offence. The Health and Safety Executive (HSE) can issue fines of up to £2,500 per day for non-compliance.
Sole traders and the self-employed: If you work alone and do not employ anyone, employers liability insurance is not legally required. However, if you use subcontractors, you should seek advice on whether they are classified as employees for insurance purposes, as this is not always straightforward.
Tools and Equipment Cover
Public liability insurance does not cover your own tools and equipment. If your tools are stolen from a van, lost on site, or damaged during work, you would need a separate tools and equipment policy to cover the cost of replacement.
Many tradesman insurance packages combine public liability, employers liability, and tools cover into a single policy. This can simplify administration and ensure there are no gaps in cover between separate policies.
Contract and Client Requirements
Many clients and contractors specify minimum insurance requirements as a condition of engagement. Common requirements include:
- A minimum public liability limit (often £2 million, £5 million, or £10 million)
- Employers liability insurance if you employ anyone
- A certificate of insurance to be provided before work commences
- The client or main contractor to be noted on the policy as an additional interested party
- Professional indemnity insurance for design-and-build or specification work
It is important to review contract requirements carefully before tendering. If a client requires a higher indemnity limit than your current policy provides, you will need to arrange additional cover before the contract can proceed.
Getting Covered
Arranging public liability insurance through a specialist broker gives you access to insurers who understand the specific risks associated with trade work. A broker can help you identify the right level of cover, ensure that your trade activities are correctly described on the policy, and provide a certificate of insurance for clients and contracts.
When approaching a broker, it is helpful to have the following information available:
- Your trade or trades (if you carry out more than one type of work)
- Your annual turnover or contract value
- The number of employees or subcontractors you use
- The types of clients and contracts you work on (domestic, commercial, public sector)
- The indemnity limit required by your clients or contracts
- Details of any claims in the past five years
