A construction loan is a primary form of senior debt used to fund the main building phase of a property development project. It is usually drawn down in tranches aligned with build progress and certified valuations. Commonly secured with a first charge, construction loans fund materials, labour, and key contractual obligations. In UK property development finance, this facility is central to delivering the physical asset and is often paired with professional monitoring, development appraisals, and staged draw conditions to manage lender risk and cost-to-complete exposure.
Within the capital stack, a construction loan typically sits as Senior Debt 1st Charge, giving the lender priority over the development asset and cashflows throughout the build phase. This senior positioning drives strict control over drawdowns, monitoring surveyor sign off, and cost reporting to ensure the scheme remains on programme and within budget. The facility is usually advanced against a defined works schedule and tightly aligned with the terms of the Building Contract, which governs delivery risk, contractor obligations, and payment milestones. For developers, the structure demands disciplined cashflow management, as any delay or cost overrun can directly affect funding availability and overall project viability.
