Programme Overrun Tolerance refers to the predefined margin of time by which a property development project can exceed its scheduled programme without triggering financial penalties, lender intervention, or increased risk exposure. In property development finance UK, this tolerance is critical for lenders and developers to manage construction delays, cash flow pressures, and contingency planning. It influences project viability assessments, drawdown schedules, and risk-adjusted returns. Programme Overrun Tolerance is often integrated into construction contracts, loan agreements, and risk monitoring frameworks to ensure projects remain within acceptable limits, balancing practical delivery flexibility with financial discipline.
This sits beneath Construction & Delivery Risk, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Delay Cost Sensitivity Index, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Programme Overrun Tolerance is most commonly encountered in connection with Waterfall-Based Profit Share within the property development capital stack.
