Tradesman Public Liability Insurance UK 2026: Cost, Cover and Providers
Public liability insurance is the single most important policy a UK tradesperson can hold. It protects you if your work causes injury to a third party or damages someone's property, and without it you would be personally liable for legal costs and compensation that can run into tens of thousands of pounds. This guide covers what PLI actually covers, how much it costs by trade, which providers to consider, and what the policy will not pay for.
Quick Answer
Is public liability insurance a legal requirement for tradespeople in the UK?
Is PLI a Legal Requirement?
Public liability insurance is not legally required for self-employed tradespeople in the UK. There is no law that compels a sole trader plumber, electrician or builder to hold a PLI policy before starting work.
The practical reality is different. Most principal contractors will not allow an uninsured subcontractor on site. Housing associations and local authorities require proof of PLI as a condition of any contract. Domestic clients are increasingly asking to see a certificate before work begins. A tradesperson without PLI is not breaking the law, but they are significantly limiting the work they can take on.
The rules change the moment you employ anyone. Employers' liability insurance is legally required for any business with employees, including part-time workers, casual labour, and temporary staff. The statutory minimum is £5 million and you must display the certificate at your premises. Failure to hold valid employers' liability insurance carries a fine of up to £2,500 per day.

What affects your PLI premium?
Annual turnover
Higher turnover means more job exposure and a higher premium
Number of employees
Each worker you employ or subcontract increases the risk profile
Trade type
Roofers and scaffolders pay the most; painters and decorators the least
Claims history
Prior claims add 10 to 30% to your renewal premium
Level of cover
£1m vs £2m vs £5m makes a meaningful difference to price
Work type
Commercial jobs attract higher premiums than domestic work
How Much Cover Do You Need?
Most UK insurers offer PLI at three main levels: £1 million, £2 million and £5 million. The difference in annual premium between £1 million and £2 million is usually small enough that most tradespeople opt for at least £2 million as a baseline.
Minimum acceptable cover for low-risk domestic work. Some clients and housing associations will not accept this level.
Best for: Sole traders doing small domestic jobs only
The most common level among UK tradespeople. Accepted by most housing associations and standard domestic clients.
Best for: Most sole traders and small businesses
Required for local authority contracts, NHS work, larger commercial sites, and most principal contractor requirements.
Best for: Anyone doing commercial or public sector work
What PLI Covers and What It Does Not
Understanding the exclusions is as important as knowing what is covered. Many claims disputes arise because a tradesperson assumed their PLI would pay for something that is explicitly excluded.
What PLI covers
- Third-party bodily injury (e.g. client trips over your equipment)
- Third-party property damage (e.g. you accidentally flood a floor)
- Legal defence costs if a claim is made against you
- Emergency medical treatment costs you are liable for
- Damage to a neighbouring property caused during work
What PLI does NOT cover
- Damage to the property you are actively working on
- Your own tools, equipment or van
- Your own employees (requires employers' liability)
- Defective workmanship claims for your own faulty work
- Professional negligence or design errors
- Work at height above limits specified in the policy
- Hot works without adequate fire watch (some policies)
- Theft of tools or materials
To cover the property you are working on, you need contract works insurance (also called contractors all-risk insurance). To cover defective workmanship, professional indemnity insurance is the relevant policy. See our tradesman insurance overview for a full breakdown of all policy types.
