Quick answer: what public liability is for (and what it isn’t)
Public liability insurance is designed to protect your business if a third party claims you caused injury or damage to their property in connection with your work. It’s often used by trades, contractors and service businesses working in customer premises, commercial sites or public areas.
Third-party injury and third-party property damage claims (subject to policy terms and acceptance).
Your own tools, your own injuries, employee injuries, pure poor workmanship, or advice/design errors.
If you’re comparing price, see Public Liability Insurance Cost (UK). If a client asks for a specific limit, check £5m vs £10m Public Liability. Need proof? Use PL Certificate (UK).
The biggest things public liability insurance usually does NOT cover
These are the exclusions that most often surprise people. In most UK policies, they are either excluded outright or require a different type of cover.
1) Poor workmanship / your work needing redoing
If a customer says “the finish is poor” or “the job needs redoing”, public liability usually isn’t designed to pay to redo your work. Public liability is primarily about third-party injury or third-party property damage — not quality disputes.
2) Your own tools, kit and equipment
Public liability typically doesn’t cover theft or damage to your own tools or equipment because that’s not third-party property. (This is usually handled by tools cover or a broader trades package, depending on the provider.)
3) Employee injuries (you’ll need employers’ liability)
If you employ anyone (including some casual arrangements), injury claims by employees are not usually covered by public liability. You may need Employers’ Liability Insurance.
4) Professional advice, design or specification errors (often needs PI)
If your work involves advice, design, drawings, specifications, surveys, consultancy or “professional services”, public liability may not respond to pure financial loss arising from that advice. That’s where Professional Indemnity Insurance can be relevant.
5) Your own injury
Public liability is about third parties. It typically does not cover your own injury at work. (Some businesses look at personal accident cover for that risk.)
6) Motor incidents
If an incident involves a vehicle on the road, that’s usually handled by motor insurance rather than public liability.
7) Deliberate acts and illegal activity
Deliberate damage and illegal acts are typically excluded.
8) Certain “special risks” unless declared
Some higher-risk activities (e.g., certain types of working at height, hot works, specialist contracting) may require specific declaration or endorsements. If you do higher-risk work, make sure your activities are described accurately.
Most claim problems come from buying the cheapest policy with an activity description that doesn’t match reality. Start a quote with accurate details: Start Quote.
Grey areas that cause disputes (where people get caught out)
Grey areas are where people assume they’re covered — but the insurer asks questions, points to exclusions, or says the work wasn’t declared. These aren’t guaranteed exclusions, but they are common “friction points”.
Some policies have limits on working at height or excavation depth, or require it to be declared. If you do roof work or trees, be extra clear about your activities.
Heat-related activities can have conditions (risk controls, declarations, exclusions). If you’re unsure, compare policies and check endorsements before buying.
If you sign a contract agreeing to liabilities beyond normal negligence, some policies may not cover that extra exposure. Read what you’re signing and keep wording aligned with your insurance.
If you supply goods/products as well as services, product-related claims can behave differently. See Product Liability Insurance.
If clients require higher limits for these environments, see: £5m vs £10m Public Liability.
Real-world examples: what’s covered vs not covered (typical outcomes)
Policies and insurers vary, but these examples show how public liability is usually intended to work — and where people misunderstand it.
| Situation | Typical outcome | Why | Best next step |
|---|---|---|---|
| A customer trips over your cable/ladder and is injured | Often covered | Third-party injury claim (subject to terms and evidence) | Keep good records + ensure your work type is declared |
| You scratch a customer’s floor while moving materials | Often covered | Third-party property damage | Check your limit and excess; see cost guide |
| Your tools are stolen from your van overnight | Usually not | Your own property, not third-party property | Consider tools cover (if relevant in your policy bundle) |
| You fitted something poorly and it needs redoing | Usually not | Poor workmanship/quality dispute (not injury/property damage) | Clarify scope + expectations in writing |
| Your advice/specification causes a financial loss | Often needs PI | Professional services and “pure financial loss” can fall outside PL | See Professional Indemnity |
| An employee is injured on the job | Needs EL | Employee claims usually sit under employers’ liability | See Employers’ Liability |
| You supply a product that later injures someone | May need product cover | Product-related claims can require product liability | See Product Liability |
| A client refuses onboarding without a £10m certificate | Not a claim — admin | They need the certificate to match contract requirements | See £5m vs £10m + certificate |
The policy is “cheap” because it doesn’t match the work. Compare options with the right activity description: Start Quote.
How to avoid claim rejection (practical checklist)
You can’t control every claim outcome, but you can massively reduce the risk of “not covered” surprises by tightening up these basics.
- Describe your work accurately (avoid vague categories if you do specialist work).
- Don’t understate turnover to get a cheaper price — it can create disputes later.
- Confirm where you work (domestic vs commercial vs public areas).
- Check height/depth/hot works if relevant to your trade.
- Match the cover limit to your contracts (some require £5m or £10m).
- Keep your certificate current and saved for quick sending.

Limits matter: £5m vs £10m (and why clients care)
Many “not covered” problems aren’t about exclusions — they’re about contracts. If your client requires £10m and you only have £5m, you can fail onboarding even though you “have public liability”. This is extremely common on commercial sites and public sector work.
£5m vs £10m Public Liability Insurance (UK) explains when £10m is required, when £5m is enough, and how to compare the uplift.
Trade pages: exclusions differ by work type (use the right guide)
The fastest way to avoid mismatched cover is to start from your trade page and ensure your activities match. Here are your internal trade guides for stronger interlinking.
| Trade | Why exclusions matter here | Guide |
|---|---|---|
| Electricians | Public areas, cables/trip risks, high-value property | Electricians PL |
| Plumbers | Water damage severity + landlord requirements | Plumbers PL |
| Builders | Broader activities = higher chance of mismatched cover | Builders PL |
| Roofers | Working at height conditions are common “grey areas” | Roofers PL |
| Tree surgeons | High severity incidents + public spaces | Tree Surgeon PL |
| Cleaners | Slip claims + commercial site requirements | Cleaners PL |
| Painters & decorators | Damage disputes on finished surfaces | Painters & Decorators PL |
| Carpenters & joiners | Second-fix, kitchens, high-value finishes | Carpenters & Joiners PL |
| Landscapers | Public-facing work + property damage exposure | Landscapers PL |
| Flooring contractors | High-value surfaces increase claim severity | Flooring Contractors PL |
| Heating engineers | Risk profile differs by work type (domestic vs commercial) | Heating Engineers PL |
