Time Overrun Risk in property development finance UK refers to the potential for a development project to extend beyond its scheduled completion date. Delays can arise from planning issues, construction setbacks, supply chain disruptions, or regulatory approvals. Such overruns may increase holding costs, interest payments, and working capital requirements, affecting the project’s return on investment. Lenders and developers carefully monitor schedules to mitigate this risk, linking project timelines to funding drawdowns and milestone payments. Accurately assessing and managing Time Overrun Risk is essential for maintaining cash flow, meeting loan conditions, and ensuring timely delivery of property development projects.


This sits beneath Time Efficiency, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Programme Overrun Probability, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Time Overrun Risk is most commonly encountered in connection with Deferred Comp + Equity within the property development capital stack.
