A guarantor is a third party who provides a legally binding undertaking to fulfil the borrower’s obligations under a property development finance agreement in the event of default. In UK development funding, this is often a director, shareholder, or related company offering additional security to the lender. The guarantee may be limited or unlimited in scope and can cover loan repayment, interest, costs, or other liabilities. Guarantors are usually required to undergo due diligence and are named in the facility documentation.
In practice, a guarantor provides lenders with an additional layer of recourse where the borrowing entity has limited assets outside the development project itself. This is particularly relevant in special purpose vehicle structures, where repayment depends heavily on project delivery, sales performance, or refinancing outcomes. As a result, the strength, financial standing, and covenant profile of a guarantor can influence lending terms, facility size, and overall credit assessment. Within the wider framework of Parties and Roles, the position is closely connected to the Original Guarantor, particularly where guarantees remain in force despite changes in ownership, corporate structure, or borrower arrangements during the life of a development facility.
