The Undrawn Facility Ratio assesses the unused portion of a property development finance UK facility relative to the total committed funding. It demonstrates a developer’s liquidity cushion and ability to meet unforeseen costs during a development project. Calculated as undrawn facility divided by total facility, this ratio is a key indicator for lenders and developers to evaluate financial resilience, risk exposure, and funding flexibility. High ratios indicate strong liquidity availability, supporting contingency planning and stress management, while lower ratios may signal tighter access to immediate funds for construction, acquisition, or development-related expenses.
This sits beneath Liquidity Coverage & Availability, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Liquidity Reserve to Total Project Cost, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Undrawn Facility Ratio is most commonly encountered in connection with Development Top-Up Bridge within the property development capital stack.
