Property development finance is one of the most specialised lending products in the UK market. It requires developers to understand a set of concepts - GDV, LTGDV, monitoring surveyors, drawdown schedules - that are specific to this form of lending and not well understood by many first-time and even experienced developers. This comprehensive guide explains every element of UK development finance from the developer's perspective.

Sizing and structuring a development finance facility
Development finance facilities are sized against the Gross Development Value (GDV) of the completed scheme, not the cost. Typical senior development finance advances 60-65% of GDV, covering both land costs and build costs up to this cap. This is expressed as LTGDV (loan-to-GDV). On a scheme with a £2M GDV, senior development finance would advance up to £1.2M-£1.3M.
Where the developer needs more than 65% LTGDV, mezzanine finance can be layered above the senior. Mezzanine typically advances to 75-85% LTGDV at a higher rate, reflecting its junior position in the security stack. Some specialist lenders offer combined senior/mezzanine products at slightly higher rates but with simpler administration than managing two separate lenders.
The drawdown process and monitoring surveyors
Development finance does not advance in a lump sum. It is drawn down in tranches as construction milestones are reached and verified. The lender appoints a monitoring surveyor (QS) who visits the site before each drawdown, verifies that the work has been completed to the required standard and in accordance with the approved plans, and certifies the drawdown request.
The monitoring surveyor's fee (typically £5,000-£15,000 depending on project scale) is borne by the borrower and is a non-negotiable condition of development finance. Developers should budget for these costs from the outset and ensure that their build contract and programme are structured to align with the expected drawdown schedule.
"Every element of a development finance facility is negotiable at origination. Developers who understand the mechanics get better terms than those who simply accept the initial offer."

Exit strategies and repayment
Development finance must be repaid at or before the backstop date specified in the facility agreement. This date is typically 3-6 months after the expected completion date, providing a buffer. The exit options are: sale of completed units, refinancing to a term investment loan, or a combination. Each exit must be modelled in the initial appraisal to confirm viability.
The risk of not achieving the modelled exit price or timeline is significant and needs to be stress-tested. A development appraised on the assumption of achieving current market prices at practical completion has embedded risk if the market moves during the build period. Conservative exit assumptions and adequate contingency reserves are essential in any properly structured development appraisal.

Frequently Asked Questions
What experience do development finance lenders require?
Senior development finance lenders typically require the developer to have completed at least one previous residential or commercial development of comparable scale. First-time developers need a more experienced build team and are often required to contribute more equity.
Can I use development finance to fund a commercial development?
Yes. Commercial development finance (offices, retail, industrial) works similarly to residential, but the exit via investment mortgage is typically at lower LTV and the mezzanine/senior split may differ.
How is interest handled during a development project?
Interest on development finance is typically rolled into the loan rather than paid monthly. This preserves the developer's cash during the build period and is repaid in full at exit.

UK developers who take the time to understand the mechanics can access competitive facilities and structure their projects to minimise cost and risk.
