The Pre-Let Coverage Ratio is a key financial metric in UK property development finance that measures how well anticipated rental income from pre-let agreements covers the interest payments on a development loan. It is calculated by dividing projected net rental income by expected interest costs during the development phase. Lenders and developers use this ratio to evaluate the early financial strength and risk of a scheme before full lettings are achieved. A higher ratio indicates greater confidence in meeting loan obligations from secured tenants, supporting lending decisions alongside metrics like Loan to Value (LTV) and overall project yield.
This sits beneath Interest Coverage, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Pre-Let Covenant Ratio (Net Rent ÷ Debt Service), as both are closely related measures used to assess similar aspects of performance or risk.
