How To Read Construction Insurance Clauses

Construction contracts should be checked for required public liability limits, employers' liability evidence, contract works responsibility, professional indemnity requirements, joint names wording, existing structures, plant obligations and evidence deadlines before work starts.

The certificate alone may not answer every requirement. Contractors should compare the policy wording with the contract schedule, because exclusions, excesses, height or heat conditions and subcontractor rules can matter as much as the headline limit.
