The S278/S106 Infrastructure Dependency Score measures the extent to which a property development project relies on third-party obligations, including S278 highways agreements and S106 planning contributions. These legal requirements typically concern site access, infrastructure delivery, and planning approvals. A higher score signals increased exposure to potential delays, cost overruns, and regulatory hurdles, which can impact project timelines and financing arrangements. In UK property development finance, this score is crucial for lenders and developers to accurately assess construction risks, optimise cash flow planning, and allocate contingencies, thereby supporting effective risk management and well-informed funding decisions.
This sits beneath Construction & Delivery Risk, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Site Servicing Plan Robustness Score, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, S278/S106 Infrastructure Dependency Score is most commonly encountered in connection with Waterfall-Based Profit Share within the property development capital stack.
