Quick answer

The direct answer

Tradesman insurance for builders is not one policy but a stack. The core is public liability — typically £120–£300 a year for a sole trader at the £2 million limit most domestic clients expect. On top of that sit the optional layers: tools cover (usually £60–£160 a year for a £2,500 kit), contract works for jobs you would have to rebuild if damaged mid-project, and personal accident cover. One layer is not optional: the moment you employ anyone — including labour-only subcontractors — the law requires employers’ liability insurance of at least £5 million, and trading without it risks a fine of up to £2,500 for every uninsured day. A full combined builders package bringing all of this together typically lands between £200 and £800 a year in 2026.

Pricing

What builders pay for tradesman insurance in 2026

The figures below are typical annual premiums for an established sole-trader builder with no recent claims, drawn from published UK price indices and cost guides in 2026. Riskier work — roofing, structural alterations, heat work — pushes premiums towards the top of each range, while a clean claims history, a voluntary excess and paying annually pull them down.

Cover explained

What a builder’s policy covers — and who needs which layer

Public liability is the foundation. It pays compensation and legal costs if your work injures a member of the public or damages their property — a dropped scaffold board, a burst pipe behind a wall, a client tripping over your materials. It is not a legal requirement, but in practice you cannot work without it: most domestic clients, all main contractors and every local authority tender will ask for proof, usually at £2 million for domestic work and £5 million for commercial or contractor-led sites.

Employers’ liability is the legal layer. Under the Employers’ Liability (Compulsory Insurance) Act, any UK business that employs staff must hold at least £5 million of cover, and the penalty for trading without it is up to £2,500 per uninsured day. The trap for builders is labour-only subcontractors: if a subbie works under your direction, on your programme, with your materials or tools, the law generally treats them as your employee for insurance purposes — regardless of how HMRC taxes them. Bona-fide subcontractors who quote for a package of work, carry their own insurance and supply their own kit usually fall outside the duty, but you should collect and check their certificates every time.

Tools and equipment cover matters more than most builders expect. UK trades lost an estimated £99 million to tool theft in 2025, a theft was reported roughly every 20 minutes, and the average claim reached £2,646. Policies differ sharply on the detail: some exclude tools left in a van overnight entirely, others pay only if the van was locked, alarmed and forced open. Read the overnight condition before you buy, not after the claim.

Contract works: covers the partially built job itself — if a storm, fire or theft wrecks an extension at first fix, this pays to redo the work. Essential for new builds and structural projects.
Personal accident: pays a weekly benefit if injury stops you working — the self-employed get no sick pay, so this is the income backstop.
Plant cover: for owned or hired-in diggers, mixers and access kit; hire agreements usually make you liable for the machine.
Professional indemnity: only needed if you provide design as well as build — design-and-build contracts increasingly require it.

What moves the price most: your trade mix (roofing, demolition and heat work cost more than general building), annual turnover, number of employees, cover limits, voluntary excess, claims history and postcode. Insurers price builders individually, which is why published ranges are wide — and why comparing quotes rather than auto-renewing typically saves the most.

Common questions

Builders’ insurance FAQs

How much is tradesman insurance for a builder in 2026?

A sole-trader builder typically pays £120–£300 a year for £2 million public liability in 2026, with entry prices from around £7.32 a month. A combined package adding tools cover, employers’ liability and personal accident usually lands between £200 and £800 a year depending on turnover, staff and claims history.

Is public liability insurance a legal requirement for builders?

No — public liability is not required by law for any UK trade. In practice it is unavoidable: main contractors, local authorities and most domestic clients will ask for proof before you start, and many contracts specify a minimum limit of £2 million or £5 million. The only legally compulsory cover is employers’ liability once you employ anyone.

Do I need employers’ liability if I only use subcontractors?

It depends on the type. Labour-only subcontractors — paid for their time, working under your direction with your materials — count as employees for insurance law, so you need employers’ liability at £5 million minimum. Bona-fide subcontractors who price a package of work and carry their own insurance usually do not, but always collect their certificates and check the limits.

How much cover do I need — £1m, £2m or £5m?

£2 million is the working standard for domestic building; £5 million is commonly demanded for commercial sites, council frameworks and main-contractor work. The step from £1m to £5m often costs surprisingly little — typically well under £100 a year extra — so most builders buy more than the bare minimum rather than risk being turned away from a job.

Does tradesman insurance cover tools left in my van overnight?

Only if the policy says so — and the conditions are strict. Many insurers exclude overnight van storage completely, others cover it only if the van was locked, fitted with an alarm or deadlocks, and shows evidence of forced entry. With the average tool-theft claim at £2,646 in 2025, this single clause is worth checking before anything else in the wording.

What is contract works insurance and do builders need it?

Contract works covers the job itself while it is unfinished — if fire, flood, storm or theft destroys a half-built extension, it pays the cost of redoing the work and replacing materials. Public liability will not do this. Any builder taking on new builds, extensions or structural work should price it; JCT-style contracts often require it explicitly.

What affects the price of a builder’s policy most?

The biggest drivers are the type of work you do (roofing, demolition and heat work sit in higher rating bands than general building), annual turnover, how many people you employ, your chosen cover limits and excess, your claims record and your postcode. Working at height or on structural jobs moves you up a band faster than anything else.

Can I pay monthly, and does it cost more?

Almost all insurers offer monthly payment, but most fund it through an interest-bearing credit agreement, typically adding 5–15% to the annual price. If cash flow allows, paying annually is usually the single easiest saving on a builder’s policy — often worth more than shaving a cover limit or raising the excess.
