Public liability insurance

Public liability covers your legal liability for accidental injury to third parties (the public, customers, visitors) and accidental damage to their property arising from your business activities. It also funds your legal defence—vital given solicitors’ rates of £150–£350 per hour outside London, and double that at City firms. It is not compulsory under statute in the UK, unlike employers’ liability under the 1969 Act, but it is functionally compulsory in many supply chains. Post‑2019, the Financial Ombudsman Service (FOS) accepts complaints from small businesses up to £6.5m turnover and up to 50 employees, which has subtly shifted market behaviour: wordings have tightened, underwriting discipline has improved, and service matters. Pricing hardened from 2020–2023 on claims inflation and reinsurance costs, then stabilised. For low‑hazard trades in 2026, a clean claim history still buys cover in double digits. For heat work, height, or heavy footfall, the floor is higher. Limits of £5m and £10m are increasingly non‑negotiable in public sector and transport procurement.

No Act forces a café, freelancer or contractor to buy PL. But several legal frameworks create exposure that only PL sensibly funds. The Occupiers’ Liability Acts 1957 and 1984 impose duties to lawful visitors and, in some cases, trespassers. The Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999 require you to manage risks to non‑employees. The Defective Premises Act 1972 bites for builders. Meanwhile, many licences and contracts mandate PL: local authority market stall permits typically stipulate £5m; councils, universities and NHS Trusts often insist on £5m–£10m; Transport for London supplier frameworks commonly require £10m. Landlords, venue hire agreements and shopping centres do the same. If you step onto a client site, sell to the public, exhibit at a fair, maintain equipment in public spaces, or run events, assume you will be asked for a certificate of insurance before you can start.

Core public liability responds when, due to your negligence, a third party suffers bodily injury or their property is damaged in connection with your business. It pays compensatory damages, claimant costs, and your defence costs. Most UK SME policies bundle public and product liability together, with the public liability limit applying “any one occurrence” (AOE) and product liability “in the aggregate” for the period. Legal defence includes representation at coroner’s inquests and Health and Safety Executive (HSE) investigations following an incident. Court attendance compensation for directors or employees is often included at fixed daily rates. Standard policies also include an “indemnity to principals” extension, covering your client where you’ve agreed to indemnify them for your negligence. Note what is not required: you do not need a claimant to have sued you before you notify the insurer. If you receive a letter of claim under the Pre‑Action Protocol for Personal Injury Claims, or a complaint alleging injury or damage, you should put insurers on notice immediately.

PL is not a maintenance contract. Exclusions are where SMEs come unstuck: damage to property in your custody or control (unless a specific “tools/plant” or “care, custody, control” extension is bought); injury to employees (that’s employers’ liability, compulsory if you employ anyone under the 1969 Act); pure financial loss unconnected to injury or damage (can sometimes be bought back as a limited “financial loss” extension, typically on a claims‑made, aggregate basis); professional advice and design (professional indemnity); defective workmanship itself (your cost to redo the job is yours—PL may cover resulting damage to third‑party property); cyber, data breach and fines (cyber insurance, with ICO oversight under the UK GDPR/Data Protection Act 2018); gradual pollution (often excluded except for sudden and accidental); hot works unless you follow strict permit conditions; work at excessive height or depth beyond stated limits; USA/Canada jurisdiction; product recall costs; asbestos and, often, underground services unless specifically covered. Read endorsements line by line and buy add‑ons only if they match real exposures.

Limit selection is not vibes; it is a blend of contract, venue requirements, and loss severity. Micro‑trades working domestic only, with no local authority contracts, often buy £1m–£2m. Any public‑facing venue, market trading, school or council work will almost certainly stipulate £5m. Rail, aviation‑adjacent, large events, or main contractor packages routinely require £10m (often structured as £5m primary plus £5m excess layer). Consider the worst‑plausible event: a member of the public suffers a life‑changing injury (spinal, brain) due to your negligence. Lifetime care and loss of earnings settlements in the UK can run into the low millions. Add legal costs, and £1m disappears quickly. Property severity can also spike—electrical work causing a terraced house fire can be £300k–£600k all‑in; a burst sprinkler in a Grade II listed venue can top £1m. If a contract demands a limit, negotiate it only with written client sign‑off and your broker’s view; don’t bluff with inadequate cover.

Pricing is gloriously unromantic. Underwriters rate by trade/hazard class, turnover, wage roll, limit required, claims history (five years), location, and specific risk features: working at height or depth; use of heat; hazardous locations (airports, rail, petrochemical, offshore); the mix of domestic versus commercial work; footfall; and your use of subcontractors. Expect to be asked for turnover split by activity, maximum height worked (e.g., above/below 10m), maximum contract value, hot‑work controls (permits, fire watches, extinguishers), and method statements/risk assessments. Previous claims matter: three small slip‑and‑trip claims can double a retailer’s premium; a single £50k property damage loss can add loadings or a larger excess. London postcodes can carry a modest loading. Buying higher limits adds cost but not linearly—going from £2m to £5m may add 10–25% for low‑hazard trades; USA/Canada exports or jurisdiction rights, if allowed, can multiply rates and excesses.

Benchmarks, excluding Insurance Premium Tax (12%) and any broker fee, for clean risks with standard terms: freelance designer or copywriter working from home: £60–£100 with £1m–£2m; domestic cleaner: £80–£150 with £1m–£2m; self‑employed electrician (domestic‑heavy, limited heat): £180–£450 with £2m–£5m; events stallholder/organiser (low‑risk stalls, local markets): £150–£600 with £5m. Add £30–£120 to step from £2m to £5m on light trades; electricians may see £75–£200. Hot works, roofing, scaffolding or working regularly above 10m changes the conversation entirely—specialist markets, higher minimum premiums, and strict conditions. For a lean micro‑business, a pragmatic annual insurance budget might be: PL £120; professional indemnity £150–£350 (if you advise/design); tools/contents £80–£200; cyber £80–£250; employers’ liability (if needed) £60–£120 when bought in a package; total cash cost £490–£1,040, plus 12% IPT on relevant lines. Excesses of £100–£500 on property damage are common; injury claims often carry no excess.

UK public liability is almost always on a claims‑occurring basis: the policy that responds is the one in force when the incident (accident causing injury/damage) happened, not when the claim is made. This matters because the Limitation Act 1980 gives claimants up to three years from the date of injury (or knowledge) to issue proceedings for personal injury, and up to six years for property damage; for children, the clock starts at 18. Keep policy records and schedules indefinitely. Beware extensions such as “financial loss” covers—they are often written on a claims‑made and aggregate basis with a retroactive date, like professional indemnity. If you buy such an extension and later switch insurers, ensure no gap in the retro date. Product liability remains occurrence‑based but aggregated, so your £5m for products can be used up across multiple incidents in a period. USA/Canada jurisdiction, if granted, may have separate aggregates and higher excesses.

Your schedule is the contract in miniature. Check: the business description precisely reflects what you do (add “including design and advice incidental to the business” if relevant); the limit of indemnity and whether it is any one occurrence or aggregate; product liability aggregate; excess for property damage (often £250–£500) and any higher excess for heat work; height/depth limits; “application of heat” conditions; territorial limits (typically Great Britain, Northern Ireland, Channel Islands and Isle of Man; Europe for temporary visits; worldwide excluding USA/Canada unless endorsed) and jurisdiction (UK courts only unless extended); endorsements adding or restricting cover; and named principals who need to be covered under “indemnity to principals”. The certificate of insurance is a one‑page proof—your insurer or broker can issue it, usually instantly via portals (Hiscox, AXA, Aviva, Markel Direct, Direct Line for Business, Tradesman Saver). If a client wants to be named, ask for an evidence of cover letter or an endorsement; do not alter certificates yourself. Keep copies with expiry dates diarised.

If you use labour‑only subcontractors (LOS), they are effectively your employees for liability purposes; your PL should cover their acts, and you may also need employers’ liability. Bona fide subcontractors (BFS) work under their own control with their own insurance; most policies require you to check and keep evidence of their EL/PL and limits—often equal to yours. Contracts increasingly demand waivers of subrogation—your insurer’s right to recover from a negligent third party. Grant them only with insurer consent; they can weaken your recovery options and load your premium. Beware broad indemnities and hold‑harmless clauses: your PL excludes “contractual liability” you assume beyond what you would have at common law (see Unfair Contract Terms Act 1977 on non‑excludable negligence for death/personal injury). Ask your broker to vet onerous terms. If you work under JCT forms, understand non‑negligent liability and project insurance arrangements; PL and the JCT 6.5.1 (now “C.1”) non‑negligent cover are not the same thing.

Most SME policies badge this section “Public and Products Liability”. Product liability covers injury or property damage caused by products you make, sell or supply, including own‑brand items. Under the Consumer Protection Act 1987, producers and own‑branders can face strict liability for defects. Typical SME wordings still require an occurrence (injury/damage) to trigger cover; they exclude recall costs and purely economic loss. Exports to USA/Canada are either excluded or tightly underwritten. If your risk is construction, don’t confuse PL with Contractors’ All Risks (CAR). CAR covers the contract works (the building project), own plant and hired‑in plant against physical loss or damage; PL sits alongside, covering your negligence towards third parties. A burst pipe damaging the works is a CAR claim; water soaking the client’s antique parquet in the lived‑in part of the house may be PL. For advice or design liability (architects, engineers, design‑and‑build), buy professional indemnity.

Do three things, fast: make the scene safe, collect evidence, and notify your broker/insurer. Do not admit liability or agree to pay anything without written insurer consent—the Insurance Act 2015 requires a fair presentation of the risk, and your duty continues at claim time. Capture names, contact details and witness statements; photographs; measurements; retained defective parts; and CCTV. Keep accident books up to date. For injuries to non‑workers that result in hospital treatment, or specified serious incidents, you may need to report to HSE under RIDDOR 2013—some reports must be made without delay. Preserve documents; instruct contractors to pause remedial work until evidence is recorded. Expect an insurer‑appointed loss adjuster or solicitor for larger claims. Cooperate, but channel communications through them. If you hit a service pipe or cable, notify utilities immediately and your insurer. If unhappy with claims handling, use the insurer’s complaints process; failing resolution, eligible SMEs can escalate to the FOS.

Go direct if your trade is simple and you know what you need; use a broker if your work involves heat, height, products, public venues or complex contracts. Brand‑name UK carriers with SME PL appetites include Hiscox, AXA, Aviva, Zurich, RSA, AIG UK, Markel, and Direct Line for Business (U K Insurance Ltd). Specialist schemes and brokers: Simply Business (aggregator), Gallagher, Towergate, Coversure, Tradesman Saver (Henry Seymour & Co.), and Markel Direct. Check FCA permissions on the Financial Services Register before you pay anyone. Membership bundles can be good value: the Federation of Small Businesses (via FSB Insurance Service) offers access to insurance broking and member‑only rates; IPSE members can buy discounted professional indemnity and PL packages (historically via Markel); APDO members have a sector‑tailored PL/PI scheme (Markel) baked into membership options. Ask about: AOE limits, product aggregates, heat/height conditions, bona fide subcontractor warranties, USA/Canada exclusions, and whether your client can be named as principal without fee.

Insurance for your business is generally an allowable expense for Income Tax/Corporation Tax, per HMRC guidance. Insurance Premium Tax (IPT) at 12% applies to UK PL premiums; insurance is VAT‑exempt, so there’s no VAT to reclaim. Code premiums in your accounts against insurance, not staff costs. Keep policy schedules, invoices and certificates filed for six years in case of HMRC queries and to evidence occurrence‑based cover. For complaints, follow your insurer’s process; if unresolved, eligible small businesses (turnover under £6.5m and fewer than 50 employees, or balance sheet under £5m) can go to the Financial Ombudsman Service. If an insurer fails, the FSCS generally protects 90% of valid claims for non‑compulsory general insurance (100% for compulsory classes). On safety, the HSE is the relevant regulator; serious incidents may attract investigation and criminal liability irrespective of insurance. If a claim involves personal data (CCTV, incident logs), ensure processing complies with the UK GDPR and the ICO’s guidance.
