What Insurance Do Subcontractors Usually Need?

Subcontractors commonly review public liability, tools cover, employers' liability, plant cover and sometimes professional indemnity, depending on how they work. The key question is whether the subcontractor is labour-only, bona fide, self-employed, employing others or carrying independent responsibility for part of a job.

Insure24 can help subcontractors compare suitable commercial insurance options and understand which certificate details may matter before site access is approved.

Core Insurance Questions

  • Whether you are labour-only or bona fide
  • Whether the main contractor expects your own public liability cover
  • Whether your tools, staff or plant need separate protection
  • Whether the contract asks for specific limits or wording

Why This Matters

Subcontractors often assume the main contractor's policy will do everything. In practice, that assumption can fail at exactly the point where a site claim, tool theft or contract dispute happens.

Common Covers For Subcontractors

  • Public liability insurance for third-party injury or property damage allegations
  • Tools insurance where portable equipment is owned or carried between jobs
  • Employers' liability where employees or workers are engaged
  • Plant or hired-in plant cover where machinery is owned or hired
  • Professional indemnity where design, specification or advice is part of the role

What To Check Before Starting Work

Subcontractors should check the contract, site rules, required insurance limits, payment conditions and certificate requirements before starting. If a main contractor asks for evidence, the policy should match the work being done rather than relying on a broad job title.

How To Present Subcontractor Risk Clearly

A good insurance discussion separates who is doing the work, who controls the work, who supplies tools or plant and who is responsible if something goes wrong. That distinction helps avoid the common problem where a subcontractor is described one way on a contract, another way on site and a third way on the insurance certificate.

Subcontractors should prepare details of their trade, typical sites, annual turnover, use of labour-only or bona fide subcontractors, maximum height or depth, heat work, tools values and any client-required liability limits. Main contractors should also check whether subcontracted payments are declared correctly and whether the policy expects certificates from bona fide subcontractors before work begins.

Subcontractor Details To Prepare

  • Trade description, site type and work activities
  • Tools, plant, materials and hired equipment values
  • Required limits, certificate wording and contract deadlines
  • Staff, helpers, labour-only and bona fide subcontractor use

Policy Areas To Check

  • Public liability and employers' liability responsibilities
  • Tools and plant cover away from the main premises
  • Professional indemnity where advice or design is included
  • Contract works and site-specific requirements

Public liability, tools cover and employers' liability where staff are used are among the most common covers.

What should subcontractors check before starting work?
