A Top-Up Facility is a variant of a Second Charge Revolving Facility, designed to release additional funds during the course of a project when certain performance or valuation milestones are met. In property development finance across the UK, these facilities are often structured to respond to enhanced Gross Development Value (GDV), improved site metrics, or successful planning gain. They allow a developer to boost available capital without restructuring the original finance package. Funds may be drawn in tranches and are generally secured on the uplifted site value under a second charge.
This structure sits beneath the Second Charge Revolving Facility, refining capital stack dynamics by introducing more granular controls over cash flow timing, risk allocation, and return sequencing without altering its subordinated position within UK development finance structures. It is typically analysed alongside the Cost Buffer Facility, as both represent flexible mechanisms used to manage volatility in development funding and protect project liquidity frameworks. In underwriting and monitoring, performance is often assessed using the Security Realisation Risk Score, which helps lenders evaluate the likelihood of effective recovery under changing project conditions.
