How to organise construction insurance for your next project

  1. Outline your project scope, contract value, timeframes and any special risks such as high-rise or complex engineering.
  2. Gather details about staff, subcontractors, equipment and prior claims history to help assess your construction insurance coverage needs.
  3. Request construction insurance quotes and review inclusions, exclusions and excesses before you confirm your policy.

Staying on top of changing building codes, workplace safety rules and client requirements is essential. Visit our news hub for updates that can affect contract works insurance, construction liability limits and income protection insurance expectations on major projects.

Manage construction site risks and downtime

Smart risk management works alongside your construction business insurance to help reduce accidents, disputes and costly delays.

  • Implement robust safety procedures and site inductions for employees and subcontractors.
  • Secure tools, equipment and materials to limit theft, vandalism and weather damage.
  • Review contract terms so your insurance aligns with indemnities, hold harmless clauses and handover milestones.

Explore practical risk checklists, case studies and guidance in our latest construction risk management articles.

Plan your construction insurance budget

Understanding construction insurance cost drivers can make cover more predictable and easier to plan for each project.

  1. Estimate project values, annual turnover and payroll to gauge likely contract works and liability premiums.
  2. Consider optional covers such as income protection insurance for key people or additional equipment breakdown cover.
  3. Use our calculators on the insurance calculators page for general guidance when modelling different excesses and limits.
