Time to Full Let (Commercial) measures how long it takes for a commercial property to be entirely leased following completion. It is a vital consideration in property development finance UK, as full occupancy directly affects total rental income, project cash flow, and loan repayment capacity. Developers and lenders use this metric to assess risk, optimise drawdown schedules, and plan for long-term operational stability. Evaluating Time to Full Let in conjunction with Time to First Occupation and Time to 75% Let provides a full understanding of occupancy dynamics and financial performance for commercial property developments.
This sits beneath Cash Inflow Timing, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Time to Lease-Up (BTR/PRS), as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Time to Full Let (Commercial) is most commonly encountered in connection with Commercial Mortgage within the property development capital stack.
