Rework % of Cost is a key performance metric in property development finance UK, representing the proportion of a construction budget allocated to correcting defects, errors, or design changes during a development project. It is calculated by dividing the total rework costs by the total project cost and multiplying by 100. Monitoring this percentage provides insight into operational efficiency, quality control, and financial discipline, helping SME property developers and professionals identify recurring issues, optimise resource allocation, and reduce cost overruns, ultimately supporting more predictable project cash flows and enhanced profitability across development phases.
This sits beneath Handover & Post-Delivery Oversight, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Latent Defects Quality Score, as both are closely related measures used to assess similar aspects of performance or risk.
