When Contractors Usually Need Cover

  • Employers' liability where staff are employed
  • Public liability where clients or sites require evidence of cover
  • Tools, plant and contract works where losses would stop the job

Why Buyers Search This Question

Many contractors ask this after a client requests insurance documents, after moving from employment into self-employment, or before taking on larger site-led work. The right answer usually depends on labour model, site rules and what would happen if a claim landed tomorrow.

For a full package view, start with contractor insurance. If you work alone, compare self-employed contractor insurance. If third-party claims are the main issue, see contractor public liability insurance.
