The Cap on Contractor Liability, expressed as a percentage of the contract sum, defines the maximum financial exposure a contractor may face for losses, defects, or delays under a construction contract. In UK property development finance, this cap is a critical contractual safeguard influencing risk allocation between developer and contractor. Typical caps range from 10% to 20% of the contract value, balancing protection for the developer with the contractor’s willingness to price competitively. An overly restrictive cap may leave significant losses unrecoverable, affecting lender confidence, project risk assessment, and overall financial resilience of the development.


This sits beneath Value Engineering Metrics, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Delay Liquidated Damages Sufficiency Ratio, as both are closely related measures used to assess similar aspects of performance or risk.
