Contract works insurance can help protect the project itself while work is still in progress. It is different from liability cover because the focus is unfinished work, materials and the cost of putting damaged work right before handover.

What Is Contract Works Insurance?

Contract works insurance is designed to protect building work, materials and partially completed projects before completion. It can be important where fire, theft, flood, storm, accidental damage or site incidents could mean the contractor has to redo work or replace materials at their own cost.

Insure24 can help UK contractors compare cover where contract works needs to sit alongside liability, tools, plant and site-based insurance requirements.

Where Contract Works Becomes Valuable

  • Projects with exposed materials and unfinished work
  • Jobs where damage before handover would be expensive to re-do
  • Sites with weather, theft or accidental damage exposure
  • Contracts that make the contractor responsible until practical completion

How It Differs From Liability

Public liability is about claims from other people. Contract works is about protecting the job itself before completion. Buyers usually need both questions answered rather than choosing one and hoping it covers the other.

What Contract Works Cover Can Include

The exact wording varies by insurer, but contract works cover is usually linked to the value of the work being carried out. It may include materials on site, temporary works and the partially completed project, subject to exclusions and policy limits.

For example, a contractor refurbishing a commercial unit may face a serious loss if installed materials are damaged before the client signs off the project. Liability cover may not solve that problem because there may be no third-party claim. The issue is the value of the work itself.

Questions To Check Before Buying Cover

  • What is the maximum project value at risk before handover?
  • Are materials stored on site, in transit or away from the premises?
  • Does the contract specify who is responsible for the works?
  • Are temporary works, hired-in plant or existing structures involved?
  • Does the job involve heat work, height work, roofing or other higher-risk activity?

How To Set A Contract Works Limit

The contract works limit should reflect the maximum value exposed before handover, not just the average job size. Contractors may need to include labour, materials, partially completed work, temporary works and items awaiting installation. The figure can also change where several jobs are live at the same time or where a large project has staged payments before completion.

Policy wording should be checked against the contract. Some contracts place responsibility for the works on the contractor until practical completion, while others may include existing structures, free-issued materials or joint names requirements. Those details can affect whether a basic contractor package is enough or whether a more specific contract works arrangement is needed.

Values To Check

  • Maximum live project value before handover
  • Materials stored on site or in transit
  • Temporary works and hired-in plant exposure
  • Multiple jobs running at the same time

Contract Points

  • Who is responsible until practical completion
  • Whether existing structures are included or excluded
  • Any joint names or principal contractor wording
  • Heat, height, theft and weather conditions
