If you're a UK tradesperson thinking about insurance for the first time — or rethinking the policy you took out before you took on staff — this is the practical, jargon-free version of the conversation we have most often with new customers. It covers what tradesperson insurance actually is, who needs it, the covers most trades end up needing, and the situations in which UK customers, sites, and the law will simply not let you work without it.
What is tradesperson insurance?
Tradesperson insurance is a specialist business insurance product designed for the specific risks of UK trades — electrical, plumbing, gas, building, decorating, joinery, roofing, and landscaping. A typical policy bundles together the four covers most tradespeople will need: public liability (universally required), employer's liability (legally required if you employ anyone), tools and equipment cover (often the largest day-to-day exposure), and contract works (for the value of the job in progress). Most policies also include legal expenses for customer disputes and increasingly offer professional indemnity for design-led trades. Specialist trade policies differ from generic small-business policies in their treatment of overnight-in-vehicle tool cover, sub-contractor relationships, and JCT-style contract requirements.
Who in the UK needs tradesperson insurance?
Anyone who takes payment for trade work in the UK should hold, at minimum, public liability insurance. If you employ anyone — even one part-time apprentice or labourer — UK law requires you to hold employer's liability insurance with a minimum of £5m of cover. Sole traders working on residential customer jobs need public liability and tools cover at the absolute minimum; sub-contractors working on commercial sites typically need higher PL limits (£5m–£10m), tools cover with site-based extensions, and often contract works. Small firms with employees need the full bundle, including employer's liability and legal expenses.
The four covers most UK tradespeople need
Public liability is the foundational cover for every UK tradesperson. It pays out when a customer or member of the public is injured by your work, or when you cause damage to a customer's property — flooded floor, damaged wiring, broken pipework. Most residential customers expect £2m of cover and most commercial sites require £5m–£10m, with some larger principal contractors requiring £10m or more.
Employer's liability is the cover that responds to staff injury claims, and it is legally required for any UK business that employs anyone, with a minimum of £5m. The legal definition of 'employee' is broader than many tradespeople realise — some sub-contractor arrangements fall within scope, and the penalty for not holding cover is up to £2,500 per day.
Tools and equipment cover protects against theft, accidental damage, and loss. The single most common claim from UK tradespeople is theft from a van — particularly overnight at home or on a residential job. Specialist trade policies include overnight-in-vehicle cover with realistic conditions; many generic policies exclude this entirely.
Contract works protects the value of work-in-progress against fire, theft, vandalism, and storm damage. Critical for builders and decorators on multi-week jobs, and often required under JCT and similar construction contracts.
When you legally — or practically — need cover
UK law requires employer's liability insurance for any business that employs anyone, with a minimum of £5m of cover and a penalty of up to £2,500 per day for non-compliance. Beyond that, there is no UK law that obliges every tradesperson to hold cover, but the practical requirements amount to the same thing. Residential customers increasingly require evidence of public liability before letting you start. Commercial sites and principal contractors universally require evidence of public liability (typically £5m–£10m), employer's liability if you have staff, and often contract works. Trade bodies — NICEIC, Gas Safe, FENSA, NHBC — frequently require specific levels of cover as a condition of registration. Local authority and council work usually requires £10m of public liability.
What affects the cost of tradesperson insurance in the UK
Tradesperson insurance is risk-priced — every trade's premium is calculated against a small set of factors. The most material are: the trade itself (electrical, gas, and roofing are rated differently to decorating or carpentry), your annual turnover, the value of your tools and how you store them overnight, whether you employ anyone or use sub-contractors, the kinds of contracts you take (residential vs commercial vs JCT-led), your claims history, your trade body memberships and certifications, and the levels of cover you select. The most accurate way to understand what you'd pay is to get a quote tailored to your work.
Five things to check before you buy
1. Whether tools cover includes overnight-in-vehicle. The single most common gap in generic policies — and the single most common claim.
2. Whether employer's liability is included if you have any staff. Legally required, and the legal definition of employee includes some sub-contractor arrangements.
3. Whether contract works is included. Required under most JCT contracts and many commercial site rules.
4. Whether public liability limits match your typical contracts. £2m is the residential standard; £5m–£10m is typical for commercial sites; £10m+ for some principal-contractor and council work.
5. Whether legal expenses are included. Often the most-used element of any tradesperson's policy in any given year — covers customer disputes, recovery actions, and contract claims.
