Senior Debt 1st Charge is the main loan secured against a development site or property. It holds the first legal charge, meaning it has priority in repayment over all other forms of finance in the event of a default or sale. In UK property development finance, senior debt typically funds the bulk of acquisition and construction costs. It is lower risk for lenders due to its security position and often comes with lower interest rates than subordinated debt or equity. The lender’s rights are enforceable first, making it the most protected capital layer in the stack.
Within the wider Debt structure, Senior Debt 1st Charge defines the foundation of lender priority and risk allocation, sitting ahead of all subordinate capital including Subordinated Debt 2nd Charge. Its position is formalised through a Legal Mortgage, giving the lender enforceable rights over the asset and control in downside scenarios. For developers, this layer typically dictates the overall funding envelope, with quantum and pricing closely tied to scheme viability and risk profile. Ongoing performance and funding headroom are commonly monitored using measures such as Capital Structure Leverage, ensuring the senior lender remains adequately protected throughout the development lifecycle.
