How to Access Development Finance in the UK

15 July 2025

The Funding Behind Every Build

Property development requires capital—often far beyond the reach of personal funds or buy-to-let mortgages.

That’s where development finance comes in. It’s the engine behind:


  • New builds
  • Conversions
  • Heavy refurbishments
  • Mixed-use schemes
  • Commercial-to-residential projects


In 2025, demand for development funding remains high, and lenders are still eager to back viable schemes—provided they’re well structured.


What is development finance?


Development finance is a short-term loan that funds:


  • The acquisition of land or property
  • The cost of construction or renovation
  • Sometimes the professional fees and contingency


The loan is repaid upon:


  • Sale of the completed units
  • Refinance onto long-term debt
  • Exit via another developer or investor


Terms are typically 6 to 24 months, and funds are drawn in stages as the project progresses.


Who uses development finance?


๐Ÿงฑ First-time developers (with good support team)
๐Ÿ—๏ธ Experienced developers scaling projects
๐Ÿ˜๏ธ SME builders and construction firms
๐Ÿข Landowners converting or upgrading stock
๐Ÿก Homeowners undertaking significant rebuilds


If you’re planning to build or refurbish at scale, development finance is likely the best route.


How much can you borrow?


Lenders assess the loan based on two key figures:


  • Loan to GDV (Gross Development Value): How much they’ll lend vs. the final sale value
  • Loan to Cost (LTC): How much they’ll fund of your total costs


Typical ranges in 2025:


๐Ÿ“ˆ Up to
70% of GDV
๐Ÿ’ฐ Up to
85–100% of build costs
๐Ÿก Up to
50–75% of land/property purchase price


You’ll need to contribute some equity—though mezzanine lenders and JV partners can sometimes top this up.


What does development finance cost?


Costs vary depending on experience, risk, and leverage. Expect:


๐Ÿ’ธ Interest: From 7%–12% per annum (often rolled up)
๐Ÿ”
Arrangement fees: 1%–2%
๐Ÿงพ
Exit fees: 1%–2% (sometimes based on GDV)
๐Ÿ”
Valuation and QS fees
๐Ÿงฎ
Legal and monitoring costs


A broker can often negotiate blended rates or introduce senior + mezzanine structures to optimise pricing.


What types of development finance are available?


๐Ÿ“ Land with planning

Funds the purchase of land that already has planning permission. Higher LTVs available with full planning.


๐Ÿ“„ Land without planning

Riskier. Requires strong experience and evidence of planning potential. Expect lower LTV and higher pricing.


๐Ÿš๏ธ Heavy refurbishment

Funding for projects involving structural changes, extensions, or reconfigurations.


๐Ÿงฑ Ground-up development

For brand-new builds on vacant or cleared land. Includes multi-unit residential, commercial, or mixed-use.


๐Ÿงฎ Development exit finance

Allows developers to repay existing finance and gain more time to sell units. Typically cheaper than original funding.


What do lenders want to see?


To get approved, lenders want:


๐Ÿ“Š A detailed development appraisal
๐Ÿ“
Plans and planning permission documents
๐Ÿ“
CV of the developer and contractor
๐Ÿ’ฐ
Evidence of equity or capital contribution
๐Ÿ“ˆ
Realistic GDV and exit strategy
๐Ÿ“„
JCT contracts or build schedule
๐Ÿ› ๏ธ
Contingency and cost buffers (usually 5–10%)


The better your preparation, the stronger your application.


Exit strategy is everything


Development lenders care most about how you’ll repay the loan.


Exits include:


  • Selling the finished units
  • Refinancing onto BTL or commercial mortgage
  • Refinancing with JV partner or longer-term investor
  • Selling the site mid-development (less common)


If your exit is a remortgage, make sure rental coverage or yield supports the new debt.
