Contractor insurance for UK trades, builders and subcontractors

What is contractor insurance?

Contractor insurance is business insurance for people and companies carrying out work on client sites, construction projects, commercial premises or domestic properties. It can combine public liability, employers' liability, tools, plant, contract works and professional indemnity depending on the work and contracts involved.

Insure24 helps UK contractors match cover to the way they trade: self-employed or limited company, staff or subcontractors, small jobs or larger contracts, standard work or specialist site access requirements.

What Contractor Insurance Can Cover

Different contractor setups need different combinations of liability, equipment, contract-focused and evidence-ready protection.

Liability & Contract Covers

  • Public liability insurance for contractors working on site, in homes or at commercial premises.
  • Employers' liability insurance where you employ staff or use labour-only subcontractors.
  • Professional indemnity for contractors giving advice, design input, plans, specifications or project guidance.
  • Contract works cover for building work, installations, refurbishments and work in progress.
  • Contractual liability review where contracts, frameworks or site access documents set minimum limits.
  • Products liability where supplied items, fitted parts or installed materials create an after-completion risk.

Tools, Plant & Business Protection

  • Tools insurance for theft, accidental damage and loss from vans, sites or locked storage.
  • Plant and machinery cover for owned equipment and hired-in plant where relevant.
  • Goods in transit insurance where tools, materials or equipment are regularly moved between jobs.
  • Portable equipment cover for laptops, testing equipment and mobile devices used away from base.
  • Cyber and data cover for contractors with client-system access, remote working or digital exposure.
  • Legal expenses and tax investigation support for wider business protection.

Construction & Engineering Insurance

Many larger or more complex projects need broader cover. If your work involves infrastructure, civil engineering, highways, rail or utilities, compare specialist construction insurance and road maintenance insurance options.

How Much Does Contractor Insurance Cost?

Premiums vary depending on your trade, turnover and overall risk exposure.

Typical Pricing Factors

  • Type of work, from lower-risk trades to higher-risk site activities.
  • Annual turnover and contract values.
  • Number of employees or subcontractors involved.
  • Claims history and insurer appetite for the trade.
  • Level of cover required, often GBP 1 million, GBP 5 million or GBP 10 million.

Cost Guidance

  • Low-risk trades: from GBP 5 to GBP 15 per week.
  • Medium-risk contractors: roughly GBP 15 to GBP 40 per week.
  • Higher-risk construction work: GBP 50+ per week.

The right structure still matters more than the lowest headline premium, especially where site access, plant use, subcontract labour or contract wording can change the real risk.

Contractor Insurance For Different Business Types

Self-employed contractors: usually start with public liability insurance and then add tools cover or goods in transit insurance where equipment is moved between jobs.

Subcontractors: often need cover that reflects whether the arrangement is labour-only or bona fide, which is why many buyers move from this page into insurance for subcontractors.

Limited company contractors: may need a wider mix of public liability for contractors, employers' liability and professional indemnity depending on the contracts they sign and the work they deliver.

We needed cover that would satisfy the site paperwork, protect our tools and still make sense for how we actually use subcontract labour. Insure24 helped us structure it properly instead of just focusing on the lowest headline premium.
