Practical Completion Slippage describes delays in achieving practical completion, the stage when a property is sufficiently finished for handover or occupation, within UK property development projects. Such delays can affect scheduled lender drawdowns, disrupt cash flow projections, and increase holding costs, putting pressure on project budgets. Common causes include construction setbacks, regulatory inspections, or design changes. In the context of property development finance UK, effectively managing slippage is essential to preserve project profitability, control risks, and maintain strong developer-lender relationships. Timely identification and mitigation of slippage supports compliance with loan terms and ensures smoother financial planning throughout the development process.
This sits beneath Handover & Post-Delivery Oversight, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Stabilisation Period Length, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Practical Completion Slippage is most commonly encountered in connection with Senior LP (Priority Equity) vs Junior LP (Residual Only) within the property development capital stack.
