A development site can look profitable until the funding structure is tested, which is why developers searching for development finance UK need to look past the headline rate. In our specialist property finance work, the harder questions are usually about cash required at the start, when build money is released, what evidence the lender will expect and how the debt is repaid if the project takes longer than planned.
Criteria from specialist lenders show how wide the range can be. Some advertise development facilities from £1m to £30m, up to 85% loan to cost and terms up to 36 months, while others offer loans from £1m with first-charge lending up to 70% of value over similar terms. Those are lender-specific figures, not market rules.
How Does Development Finance Work in Practice?
Development finance is short-term property funding used for construction, conversion or substantial refurbishment, with the facility structured around the site, the works and the expected completed value. It differs from a conventional mortgage because later funds can depend on build progress and evidence from the project.
For a developer, the lender will usually examine the acquisition, build budget, professional team, valuation and proposed exit. The finished value matters, but so does the cash needed between one construction stage and the next.
Stage 1: Appraise and agree the facility
The lender assesses the site, borrower, build budget, planning position, completed value and proposed repayment route.
Stage 2: Complete and draw against progress
An initial advance may support the purchase, with later drawdowns released against evidenced work and monitoring.
Stage 3: Repay through sale or refinance
The facility is normally cleared through completed-unit sales or an appropriate refinance, so the exit is part of the credit decision from the start.
What Do Lenders Assess for Development Finance UK?
Lenders assess the whole scheme rather than a single affordability figure. Key numbers usually include the site value or purchase price, total project cost, gross development value and the borrower’s cash contribution. Loan to cost compares borrowing with eligible project costs, while loan to gross development value compares borrowing with the expected completed value.
A credible file also needs to explain who is delivering the scheme and how. Our investor-led scheme funding client story shows why ownership, valuation, structure and the parties involved can materially affect a funding case. The property is only one part of the underwriting picture.
How Is Development Finance Released During the Build?
Build funding is commonly released in stages rather than handed over in full at the start. Lenders typically draw down funds as the project progresses, charging interest only on the amount used, with further tranches released under the loan agreement following due diligence and monitoring.
For a developer, cash-flow timing matters as much as the total facility. If a drawdown follows evidenced work, contractors may need paying before the lender’s money arrives, leaving the appraisal to absorb timing differences and contingency.
What Does Development Finance Cost Beyond Interest?
The total cost is wider than the interest rate alone. Depending on the facility, a developer may face arrangement or commitment fees, valuation costs, monitoring surveyor costs, legal fees and charges linked to extensions or exit. Staged drawdowns can also change the interest bill because the full facility is not necessarily outstanding from day one, so the appraisal needs to show deductions and the cash required at each stage.
Which Funding Alternatives Should Be Compared?
The closest alternative depends on the project stage. Bridging finance can suit a short acquisition or refinancing gap, development exit finance can replace construction debt on a complete or near-complete scheme, and some lenders offer separate pre-planning acquisition finance.
| Facility | Typical Role | Main Repayment Route |
|---|---|---|
| Development finance | Construction, conversion or major refurbishment | Sale of completed units or refinance |
| Bridging finance | Short acquisition, refinance or property funding gap | Sale, refinance or replacement by development funding |
| Development exit finance | Completed or near-complete scheme awaiting sales or refinance | Unit sales or longer-term refinance |
Once construction risk has largely fallen away, our guide to development exit finance explains how an exit facility can create time for sales or refinance. Extending with the existing lender may be simpler, while refinancing may change the cost or available time; neither route is automatically preferable.
How Can the Funding Gap Appear in a Worked Example?
A simple hypothetical example makes the cash requirement clearer. Take a Wandsworth developer buying a site for £900,000, with £1.1m of build and professional costs and an expected gross development value of £2.8m. Assume, purely for illustration, a £500,000 acquisition advance and up to £900,000 of staged build funding.
The project cost before finance fees is £2m and the illustrative facility is £1.4m, leaving £600,000 of developer equity before contingency, tax and finance costs. £400,000 fills the purchase-price gap and £200,000 covers the build-cost gap. This is not a lender quote and deliberately excludes an assumed rate; it shows why day-one cash and drawdown timing matter alongside the maximum facility.
In Summary
Development finance is best understood as project funding built around acquisition, construction, evidence and exit rather than a single mortgage-style advance. Loan size, day-one cash, staged releases, fees, monitoring, planning position and the repayment route can all change the practical result, so two apparently similar offers may produce very different cash requirements.
Frequently Asked Questions
The questions below cover the points we are most likely to examine when a development funding case is first being structured.
When people search for development finance, what are they usually looking for?
The phrase development finance generally refers to short-term property funding for construction, conversion or major refurbishment projects in the UK. The facility may support acquisition and build costs, with repayment normally expected from sale or refinance when the scheme reaches the appropriate stage.
How are development finance funds released?
Funds are commonly released in stages as the project progresses rather than as one full advance at the start. A lender may require valuation, monitoring surveyor evidence and confirmation of completed work before later drawdowns are made available.
What do LTC and LTGDV mean?
Loan to cost compares borrowing with eligible project costs, while loan to gross development value compares borrowing with the expected value of the completed scheme. Lenders can apply both measures, alongside other limits, when deciding the maximum facility.
Do I need planning permission before applying?
Not in every funding scenario. Some lenders offer separate pre-planning acquisition finance, while construction or material changes of use may require planning permission under the relevant planning rules; the project-specific position should be confirmed by the appropriate planning and legal professionals.
Can a first-time developer obtain development finance?
Some lenders will consider first-time developers, while others place greater weight on a proven development record. The strength of the professional team, project appraisal, borrower equity and proposed exit can all affect whether a lender is prepared to consider the case.
How is a development finance loan repaid?
Repayment commonly comes from selling the completed units or refinancing the finished property onto another suitable facility. The proposed exit is usually assessed before the development loan is agreed because it determines how the lender expects its capital to be returned.
Is development finance regulated by the FCA?
Not always. Some development lending is business finance outside mortgage regulation, while FCA guidance uses factors including the use of at least 40% of the secured land as or in connection with a dwelling and contains exclusions for some commercial borrowers; the exact regulatory position depends on the borrower, security and purpose.
What happens if the build finishes before the units sell?
A developer may compare an extension with the existing lender, development exit finance or another refinance route, depending on the completed scheme and lender criteria. None is automatically cheaper, and the relevant comparison is the full cost, time available and credibility of the remaining sales or refinance plan.
Development funding works best when the finance structure reflects the build rather than forcing the build to fit the finance. We can assess the project, the available funding routes and the evidence lenders are likely to require, while legal, tax, valuation and planning matters remain with the appropriately qualified professionals.
