Construction Lag (Start Date to First Drawdown) measures the period between the commencement of a property development and the first release of lender funds. In property development finance UK, understanding this lag is essential for managing early-stage cash flow, ensuring sufficient liquidity for initial site works, permits, and mobilisation costs. A longer construction lag may require developers to use bridging finance or reserves, while a shorter lag can reduce interest expenses. Accurate assessment of this metric allows lenders to schedule drawdowns effectively and mitigates funding risk, supporting timely delivery of construction milestones and maintaining overall project financial stability.


This sits beneath Project Phasing Metrics, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Refinancing Execution Timeline Buffer, as both are closely related measures used to assess similar aspects of performance or risk.
