Development finance

Development finance for property developers across the UK

Senior development debt, stretched senior and mezzanine arranged through 100+ lenders, with indicative heads of terms in 3 to 5 working days, structured as a single stack so you keep more equity working across schemes.

£250k–£25m+Up to 70–75% LTGDV80% LTCFirst-time developers considered

You have a site, or a scheme you can see clearly, and the only thing between it and the first drawdown is the right funding structure. Senior debt caps below what the deal needs, and your equity is tied up in the last project. Development finance pays for ground-up builds, conversions and major works, covering the land purchase plus construction, released in stages against verified progress rather than handed over in one lump.

We do not lend our own money. We arrange finance for property development whole-of-market: we sit on your side of the table, shop a panel of 100+ lenders, and place your case with the lender most likely to fund it first time. Where one lender will not stretch far enough, we structure senior and mezzanine as a single stack so the parts fit together. There is no fee to get indicative heads of terms, and our fee model is confirmed upfront before any application, disclosed before you commit. All figures here are indicative; the lender confirms on application after the valuation and appraisal.

The mechanics

How development finance work funds a ground-up development

Development finance is staged funding for property development projects where value comes from the works. The role of development finance is to fund the build: you buy a plot or a consented site, then construct from foundations to finished units. The lender sizes a facility against your total cost and finished value, releases it in tranches against a monitoring surveyor’s sign-off, and you repay from a sale or a refinance onto a term mortgage.

Because the security is the scheme rather than your income, the lender weighs the site, the development appraisal and the exit far more than a credit score. Using development finance suits a new property build and residential property from houses to build-to-rent; commercial development and a commercial property scheme; ground up development on a cleared plot; converting a property under permitted development; and developing a property to a high standard, once your development plans and planning permission are in place. Flipping property and light works route to a refurb bridge instead.

Know your options

Different types of development finance

The layers map to where the money sits in the capital stack, so you borrow the right one at the right price.

  • Senior debt is the main development loan, first in priority and the cheapest.
  • Stretched senior extends it beyond the usual cap through a single facility, simpler than stacking a second loan.
  • Mezzanine finance is a second-layer loan behind the senior lender, pricing higher for the extra risk, that experienced developers use to push leverage and free working capital between schemes.
  • Conversion finance funds works on an existing property as a bridging loan with a refinance exit.
  • An exit bridge then sits below the build facility, a cheaper bridge to repay a completed development while units in an existing development still sell; a land bridge secures the site beforehand.
Three numbers that size the deal

How a lender sizes the loan against GDV

Three numbers decide how far your facility stretches. Loan-to-Cost (LTC) measures the loan against total development costs; mainstream senior debt funds up to 80% LTC. LTGDV measures it against Gross Development Value, the finished worth valued today; standard senior debt reaches 70% to 75% LTGDV. The day-one land advance releases against the site at the start, usually 60% to 70% of site value.

That finished value anchors the deal. The lever most developers miss is that a 65% cap is not the end of it: mezzanine or stretched senior pushes leverage to 75% to 80% LTGDV, so more of your equity stays free for the next scheme.

Total cost, not the headline

Development finance rates and the total cost of a build

Interest rates are priced per annum, and the rate is only part of the cost. A mainstream residential development prices between 6.5% and 9.5%; higher-risk schemes and first-timers sit above that. Stretched senior runs 8% to 12%, and mezzanine, when used, prices 12% to 20% behind the senior lender.

On top sit an arrangement fee, valuation, monitoring-surveyor and legal costs, with repayment usually rolled up and settled from your exit. Judge the cost against your profit, not the headline: on a typical 18-month build the total cost of finance lands at 8% to 15% of the finished value. Every figure is indicative, confirmed by the lender on application.

Whole-of-market

Using a development funding broker instead of one bank

Go direct to one bank and a property developer gets one cap and one yes-or-no; if your scheme sits outside that box, you get a decline and a wasted credit search. We hold relationships across 100+ specialist property lenders who provide development finance for property projects of every shape, plus bridging finance providers, and arrange the onward commercial mortgage when a finished scheme refinances. The lenders who fund the PD conversions, HMOs and modular schemes banks turn away bring you the best property finance deals.

That is the value development finance through whole-of-market access adds: it widens your access to finance and matches the facility to your development goals and the property market you build in, not one bank’s appetite. Securing property development finance this way means we run a soft check with your consent so exploring never marks your record, then package the development finance application so the underwriter reads a clean file. This is information, not advice; a qualified adviser confirms your case.

Straight answers

Common worries about development funding, answered straight

Is development finance only for experienced developers? +
No. Repeat operators get the keenest terms, but lenders back first-timers who have a credible team in place, usually a main contractor, a quantity surveyor and an architect, plus more equity in. We tell you whether your scheme stacks up, and if not, what to build first.
What if my scheme overruns or the exit slips? +
This is the one to plan for. We stress-test your numbers, build a contingency into the cost plan, and choose lenders whose terms give you room if the build or sales run late.
Can I fund the full cost of the scheme? +
Sometimes. Beyond a standard senior facility, 100% of cost is workable with extra security across another asset, a mezzanine layer, or an equity partner. We model the structure and tell you what it does to the total cost before you commit.

FAQ

Your development finance questions, answered

What does development finance fund? +
Ground-up builds, conversions and heavy refurbishments where you add value through works. It covers land purchase plus construction, released in stages against verified progress. It suits residential schemes, permitted-development conversions, HMOs and mixed-use projects, and is repaid when you sell the units or refinance onto a term mortgage.
How much can I borrow on a development project? +
What you can borrow is sized on eligibility against two figures: senior debt funds up to 80% of total project cost and 70% to 75% of finished value, with day-one land advances usually 60% to 70% of site value. Stretched senior or mezzanine can push past 75% to 80% at a higher rate. We weigh your finance options once we see the cost plan and appraisal. All figures are indicative.
I am a first-time developer. Can I still get funding? +
Yes, though it is harder and priced a notch higher. Lenders want relevant experience and a credible team, usually a main contractor, a quantity surveyor and an architect. First-timers normally put in more equity at a lower LTGDV. We tell you honestly whether your scheme stacks up as it stands.
How long does it take to secure development finance? +
Indicative heads of terms usually come back within 3 to 5 working days. From instruction to first drawdown is typically 4 to 8 weeks for first-time developers and 2 to 4 weeks for experienced operators who can evidence a track record. We push the valuer, underwriter and solicitors from day one.
Is development finance regulated or unregulated? +
Most development finance is unregulated, because it funds a business rather than a home you live in. Regulated development finance applies where a scheme is secured on your own residence, under Financial Conduct Authority rules, and is confirmed by a qualified adviser on the call.
What is GDV? +
Gross Development Value, the worth of the finished scheme on completion, valued today. If you build three flats expected to sell at £400k each, that figure is £1.2m. Lenders size the loan against it alongside your total project cost.
