The Complete Guide to Development Finance in the UK

Development finance is a specialist form of property lending designed specifically for developers undertaking construction projects, from ground-up residential schemes to commercial conversions and heavy refurbishments. Unlike traditional mortgages, development finance is structured around the project lifecycle, with funds released in stages as construction progresses and verified by independent quantity surveyors.

The UK development finance market offers funding from £150,000 to £100m+, catering to first-time developers through to experienced housebuilders and commercial developers. Lenders assess projects primarily on the viability of the scheme -- the relationship between costs, end value (GDV), and profit margins -- rather than solely on the borrower's personal income.

This makes development finance accessible to developers who may not qualify for traditional lending but have viable, well-planned projects. Whether you're building your first development or your fiftieth, understanding how development finance works is essential for maximising returns and minimising risk.

The mechanics revolve around two core metrics: loan-to-cost (LTC) and loan-to-gross-development-value (LTGDV). LTC represents the total loan as a percentage of total project costs. LTGDV represents the total loan as a percentage of the completed scheme's market value. Standard senior development finance typically offers up to 65% to 70% of costs and 60% to 65% of GDV. For experienced developers, stretched senior facilities can reach up to 85% to 90% of costs and up to 75% of GDV through a single loan facility.

The loan is structured in two parts: the day-one advance, which typically covers land acquisition, and the construction drawdown facility, which is released in tranches as the build progresses. Drawdowns are triggered by completion of pre-agreed milestones and verified by an independent monitoring surveyor before each release. This staged mechanism protects both lender and developer.

Developer experience is a critical factor. Lenders want evidence of successfully completed comparable projects. First-time developers face more limited options but can secure finance with strong professional teams, simpler schemes, and slightly more equity. We regularly assist first-time developers in navigating this requirement.

How Development Finance Works

From initial enquiry to completion, here is what to expect at every stage.

1

Day 1 Advance

Initial tranche released on completion to fund land acquisition. Typically 60-70% of purchase price or current market value. Some lenders offer "Day 1 Uplift" where they'll lend against a higher value if you've purchased at a discount.

2

Build Drawdowns

Construction costs released in arrears against QS-certified progress. Typically monthly drawdowns once work is verified by an independent monitoring surveyor. Up to 100% of build costs funded, reducing developer equity requirement.

3

Exit & Repayment

Loan repaid from unit sales or refinance onto term lending. Interest typically rolled up throughout and paid at exit. Development exit finance available for completed schemes awaiting sales at significantly lower rates.

Frequently Asked Questions

Everything you need to know about development finance.

How is development finance released during the project?

Development finance is released in stages aligned with your construction programme. The initial advance — typically on completion of the land purchase — covers the site acquisition and sometimes initial professional fees. Subsequent drawdowns are released as construction milestones are achieved: foundations, superstructure, wind and watertight, first fix, second fix, and practical completion. Before each drawdown, a monitoring surveyor appointed by the lender visits the site to verify that the claimed works have been completed satisfactorily and that the remaining budget is sufficient to finish the project. Once the monitoring surveyor's report is approved, the funds are released — typically within 3 to 5 working days. This staged mechanism ensures capital flows match the actual progress of the build.

What costs are involved in development finance?

Development finance costs fall into several categories. Interest is charged on drawn funds only — not the full facility — and is typically rolled up (added to the loan) and repaid at the end of the project from sales or refinance proceeds. Expect rates from 0.65% to 1.15% per month. An arrangement fee of 1.5% to 2% of the total facility is charged on completion. A monitoring surveyor is appointed at a cost of £750 to £1,500 per inspection, with inspections occurring at each drawdown stage. A valuation and development appraisal fee of £2,500 to £7,500+ covers the initial property and scheme assessment. Lender legal costs of £3,000 to £8,000+ cover the legal work on the facility. Some lenders also charge an exit fee of 1% to 1.5%. Your own professional costs — solicitor, QS cost plan, and broker fee — are additional.

Can I get development finance with limited development experience?

Yes, although your options will be more limited and the terms less favourable than for experienced developers. Many lenders will consider first-time developers if you can demonstrate relevant transferable skills — for example, a background in construction, architecture, surveying, or project management — and have assembled a competent professional team. You may need to accept lower leverage (typically 55-60% of costs versus 65-70% for experienced developers), appoint an employer's agent or project manager approved by the lender, and provide a more detailed business plan. Some lenders have specific first-time developer programmes with structured support. Starting with a smaller, simpler project and building a track record is the most effective route to accessing better terms on future developments.

What GDV and profit levels do development finance lenders require?

Most development finance lenders require a minimum profit on cost of 20% to 25%, or equivalently a profit on GDV of approximately 15% to 20%. These thresholds provide a buffer for cost overruns, sales price reductions, and time delays. Lenders will stress-test your development appraisal by increasing build costs by 5% to 10% and reducing sales values by 5% to 10% — the scheme must still demonstrate viability under these stressed assumptions. Projects with thinner margins will either be declined or offered lower leverage, requiring the developer to contribute more equity. We always recommend building realistic contingency into the appraisal rather than presenting optimistic numbers, as experienced lenders will see through unrealistic assumptions and it can undermine credibility.

What is stretched senior development finance?

Stretched senior finance is a single development loan facility that provides higher leverage than standard senior lending — typically up to 85% to 90% of total project costs and up to 75% of GDV. It effectively combines what would traditionally be separate senior and mezzanine facilities into one loan, simplifying the capital stack and often reducing the overall cost of finance. Stretched senior is available to experienced developers with proven track records, typically requiring completion of at least 3 to 5 comparable projects. The advantages include dealing with a single lender, lower total arrangement fees than dual facilities, simplified legal documentation, and often a competitive blended interest rate. The minimum project size and profit margin requirements are typically higher than for standard senior lending.

How long does it take to arrange development finance?

From initial application to first drawdown, development finance typically takes 4 to 8 weeks for straightforward schemes with all documentation in order. More complex projects — large multi-unit schemes, sites with planning conditions to be discharged, or applications requiring additional due diligence — may take 8 to 12 weeks. The main factors affecting timeline are the completeness of documentation provided at application, the time required for the development valuation (typically 2-3 weeks), the complexity of legal work including review of planning consent and building contracts, and the lender's credit committee schedule. Starting the process early and having all documentation prepared before submitting the application is the most effective way to minimise the timeline.

Show 10 more questions

What happens if my development project runs over budget or over time?

Cost overruns and programme delays are common in development, which is why lenders require contingency provisions in the appraisal. If costs exceed budget within the contingency, the lender will usually continue to fund drawdowns. If costs exceed the contingency, the developer will typically need to inject additional equity to cover the shortfall, as the lender's total exposure cannot increase beyond the approved facility. For time overruns, most development finance facilities include a provision for extension — typically 3 to 6 months — at an additional cost. Communicating early with your lender and monitoring surveyor if issues arise is critical. We maintain ongoing contact with lenders throughout our clients' projects and can intervene early to negotiate extensions or restructured terms if the project encounters difficulties.

Can development finance cover the cost of purchasing the land?

Yes, most development finance facilities include a day-one advance to fund or contribute to the land purchase. Typically, the lender will advance 50% to 65% of the site purchase price on day one, with the developer contributing the balance from their own funds. For experienced developers with strong track records, some lenders will advance up to 100% of the land cost, provided the overall facility remains within the maximum LTC and LTGDV parameters. Where a developer has owned the site for some time and its value has increased, lenders may advance against the current market value rather than the original purchase price, effectively releasing equity.

What professional team do I need for a development finance application?

Lenders expect a competent professional team to be in place before approving development finance. At a minimum, this includes: an architect who has prepared the scheme design and obtained planning consent, a structural engineer for any structural works, a contractor or building firm (ideally appointed on a fixed-price or design-and-build contract), a solicitor experienced in development transactions, and for larger schemes, a quantity surveyor who has prepared a detailed cost plan. Some lenders also require a project manager or employer's agent, particularly for first-time developers. The quality and track record of your professional team is a factor in the lending decision — lenders take comfort from experienced architects, reputable contractors, and solicitors who specialise in development work.

What is the difference between development finance and heavy refurbishment bridging?

The distinction relates to the nature and extent of works. Heavy refurbishment bridging finance covers structural works, extensions, and reconfiguration of an existing building where the fundamental structure is retained. Development finance covers ground-up construction, demolition and rebuild, and more extensive conversion projects. In practice, the line between heavy refurbishment and development is not always clear, and lenders differ in their categorisation. Development finance typically involves more detailed appraisal, monitoring, and documentation requirements, but may offer higher overall leverage and longer terms. We assess each project individually and advise whether development finance, heavy refurbishment bridging, or a hybrid approach offers the best fit.

What experience do I need for development finance?

Experience requirements vary by lender and project complexity. For smaller schemes (1-4 units), some lenders accept first-time developers with strong professional teams. Larger projects typically require a demonstrable track record of delivering similar schemes. Consider partnering with experienced contractors or starting with simpler refurbishment projects if you're new to development. We regularly help first-time developers by presenting transferable skills and assembling strong professional teams.

What deposit do I need for development finance?

With typical 65% LTGDV and 85-90% LTC parameters, developer equity usually represents 10-15% of total project costs. For a £1m project, expect to contribute £100,000-£150,000. Some lenders offer higher leverage for experienced developers with strong track records, while first-timers may need more equity. The equity must come from personal resources -- lenders do not accept borrowed deposits.

How do drawdowns work on development finance?

Build costs are released in arrears following verification by an independent monitoring surveyor. The process: complete a stage of works, request drawdown, QS inspects and certifies progress, lender releases funds (usually 5-7 working days). Most lenders operate monthly drawdown cycles. Funds are released against pre-agreed milestones such as foundations, superstructure, wind and watertight, first fix, second fix, and practical completion.

What happens if my project overruns or costs increase?

Lenders typically require 5-10% contingency in your cost plan. If costs exceed this, additional equity is usually required first. Some lenders may increase facilities if headroom exists. For time overruns, most loans include extension options (typically 3-6 months) for additional fees. Communicate early with your lender if you foresee issues -- we maintain ongoing contact with lenders throughout our clients' projects.

What GDV and profit levels do lenders require?

Most development finance lenders require a minimum profit on cost of 20% to 25%, or a profit on GDV of 15% to 20%. These thresholds provide a buffer for cost overruns and market fluctuations. Lenders will stress-test your appraisal by increasing costs and reducing sales values by 5-10% -- the scheme must still show viability under these stressed assumptions. Projects with thinner margins may be offered lower leverage.

Can development finance cover the cost of purchasing the land?

Yes, most development finance facilities include a day-one advance for land acquisition. Typically, lenders advance 50-65% of the site purchase price on day one. For experienced developers, some lenders advance up to 100% of land cost provided the overall facility stays within maximum LTC and LTGDV parameters. Where a developer has owned a site and its value has increased, lenders may advance against the current market value rather than original purchase price.
