How Development Finance Drawdowns Work

A development finance facility is not paid out in one go. The lender agrees a total facility (typically split into the land or purchase element and a build element), then releases the build money in stages as the project progresses. Each release is a drawdown, and each drawdown is triggered by physical progress on site that has been independently verified, not by an invoice or a promise. This is the mechanism that protects the lender's exposure on a half-built asset, and it is why cashflow planning matters so much on these deals.

The person who signs off each stage is the monitoring surveyor (often called an IMS or independent monitoring surveyor), appointed by the lender but paid for by the borrower. They review the initial appraisal, then visit site before each drawdown to confirm the work claimed has actually been done to standard, that costs are tracking to budget, and that the remaining money is still enough to finish. Their report is what unlocks the next tranche. A good relationship with the surveyor, and clean, well evidenced valuations of work in place, is often the difference between a same week release and a stalled site. The lender relies on that report; we do not set the schedule and the lender does not release without it.

Most development finance is drawn in arrears, meaning you fund the works first from your own cash or trade credit, then reclaim that spend at the next drawdown once it is verified. Some lenders will consider release in advance for specific line items (for example a large materials order or a groundworks contractor mobilisation), but advance drawing is the exception and is scrutinised harder because the lender is paying for work not yet standing on site. Assume arrears as the default and treat advance release as something to negotiate case by case; whether it is offered sits with the lender.

Lenders also hold back money through retention. A percentage of each stage valuation (commonly around 5%) may be retained and released only once that element is fully complete and signed off, which cushions the lender against snagging and defective work. On top of retention, the facility itself carries a contingency, usually in the region of 5% to 10% of build cost, ringfenced for overruns and the unexpected. Contingency is not spare spending money; drawing against it normally needs the surveyor to agree the overrun is legitimate. Build in a realistic contingency at appraisal stage, because a facility with a thin contingency is the one most likely to run out of road two thirds through the programme.

The interest structure is where development finance is genuinely borrower friendly on cashflow. You are charged interest only on funds actually drawn, not on the whole facility from day one. Draw slowly and interest accrues slowly. Interest is almost always rolled up (added to the loan) rather than serviced monthly, because a site under construction produces no income to pay it from. Rates are quoted in various ways and depend heavily on experience, gearing and scheme, so treat any headline figure as indicative only; the lender prices each case on its own risk. What matters for your model is that the interest bill grows as the facility fills, and it is repaid at exit alongside the principal.

For the developer, the practical consequence is a working capital gap. Because most money comes in arrears and after surveyor sign off, you carry the cost of each stage yourself before you get reimbursed, and the surveyor visit plus report can add days to that cycle. Under gearing your own cash across too many stages, or assuming instant release, is how projects seize up. The disciplined approach is to map the drawdown schedule against your subcontractor payment terms, keep a cash buffer for the lag, and front load your evidence so each valuation is easy for the surveyor to pass.

Our role as a broker is to get you to the right lender for your scheme, experience level and exit, and to package the appraisal so the drawdown mechanics work in your favour: sensible stage splits, a defensible contingency, and a programme the surveyor can sign against cleanly. We do not lend, price or decide the facility; those sit with the lender. What we do is tell you honestly which lenders will fund a scheme like yours, how their drawdown and retention terms actually behave in practice, and where a slightly different structure would ease the cashflow squeeze. Everything here is illustrative; the terms, the schedule and the decision are the lender's on your specific case.
