Development Finance Guides
Development finance explained for UK property projects — compare planning status, site value, build costs, GDV, experience, exit route, and lender fit.
Development finance explained
Use these guides to understand how property development finance is assessed, what evidence lenders need, and how planning, costs, GDV, and borrower experience shape funding options.
What to compare before funding a development
Planning position
Full planning, outline planning, permitted development, and pre-planning cases can all attract different lenders and terms.
Cost stack
Compare site purchase price, current site value, build costs, contingency, professional fees, and interest reserves.
GDV and profit margin
Lenders assess the gross development value and whether the projected margin leaves enough room for delays or cost overruns.
Drawdown structure
Development funding is usually released in stages, so check monitoring surveyor requirements and cash-flow timing.
Experience and exit
Your track record and planned exit, such as sale, refinance, or rental, can materially affect lender appetite.

Development Finance for First-Time Developers: What Lenders Need to See
First-time developers can access development finance from approximately 30-40 specialist lenders in the UK, but they'll face stricter criteria including higher equity requirements (minimum 20%), lower loan-to-value ratios (50-60% LTGDV), and higher interest rates (8-12% annually).

Interest Reserve in Development Finance: How Borrowed Interest Affects Cash Flow
An interest reserve in development finance is a portion of the loan facility set aside at the outset to cover interest payments during the build period, when the project generates no income. Rather than paying interest from their own pocket each month, developers draw from this pre-funded reserve.
Development Finance Costs UK: Interest, Exit Fees, QS Fees and Legal Costs
Development finance costs in the UK typically total 15-20% of the loan amount annually, combining interest rates of 6.5-12% per annum with arrangement fees (1-2%), exit fees (0.5-1.5%), QS monitoring fees (£1,500-£5,000), and legal costs (£4,000-£10,000).
Development Exit Finance: Refinancing a Finished Project Before Sale
Development exit finance allows property developers to refinance completed projects with lower-cost facilities while unsold units remain on the market. This short-term funding typically offers 3-18 month terms at competitive rates, releasing equity for new projects while reducing monthly interest costs compared to full development facilities.
Development Finance Drawdowns: How Stage Payments and Monitoring Surveyors Work
Development finance drawdowns are staged payments released by lenders as construction milestones are completed and certified by an independent monitoring surveyor. This process protects both lender and developer by ensuring funds are released only when work is verified complete, typically taking 10-20 working days per drawdown request.
