For Borrowers

Development Finance

Development finance is a short-term loan that pays for buying a site and building on it, with the money released in stages as the work progresses. Lenders on our panel will typically lend up to 70% of the finished scheme’s value (GDV) and up to 90% of total costs, and both first-time and experienced developers are considered.

Every property development needs the right foundations, and so does your funding. 

Whether you’re a first-time or more seasoned developer, converting an existing building or starting from the ground up, our team takes the time to structure your loan so it stacks up strongly from the start. 

We work with lenders that aren’t available to every broker and have access to the most competitive rates on the market. We can even release funds in stages aligned to the build progress, helping you manage your cash flow. We’re clever like that.

What Makes us so Clever?

When you need development finance, you need more than just the right rate; you need someone who understands build costs, timings and exactly how funding should be released.

That is why we match your project to the right lender and agree on a funding structure that reflects how the build will actually be delivered, ensuring money is available when you need it.

Whether you’re converting an existing property or taking on a ground-up scheme, our team takes the time to understand your future plans and structures the funding so it stacks up, even when the scaffolding comes down.

How much can you borrow on development finance?

Lenders size a development loan using two tests, and the loan is capped at whichever gives the lower figure.

Loan to gross development value (LTGDV) compares the loan with what the scheme will be worth once it’s finished. Loan to cost (LTC) compares the loan with what it will cost to deliver, meaning the site, the build, professional fees and contingency.

Take a site bought for £400,000, with build costs of £600,000 and £100,000 of fees and contingency. Total costs are £1.1 million and the finished units are valued at £1.6 million.

  • At 70% LTGDV, the lender could go to £1.12 million.
  • At 90% LTC, the lender could go to £990,000.

The lower figure applies, so the facility would be £990,000 and you would put in the remaining £110,000. Rolled-up interest usually sits inside the facility too, so the amount you can spend on the build is a little less than the headline loan. For a step-by-step version with fees and interest included, see our worked example of how much you can borrow on development finance.

Mezzanine and stretch senior finance

If the senior loan leaves a gap you can’t fill from your own funds, there are two ways to borrow more.

Mezzanine finance is a second loan from a separate lender that sits behind the senior lender. It raises your total borrowing, but it costs more because the mezzanine lender is paid back second, and the senior lender has to agree to it.

Stretch senior finance does a similar job in a single loan. One lender goes further on gearing than a standard senior facility, so there is only one set of legals, one monitoring surveyor and one lender to deal with. The rate usually sits somewhere between senior and mezzanine pricing.

Which one suits depends on your margin, how much you need to bridge and how much the extra borrowing costs against your profit. We’ll model both before you commit.

Development exit finance

Development finance is designed to be repaid when the units sell or the scheme is refinanced. If the build finishes before the sales do, development exit finance can repay the development loan and give you more time to sell or let.

Exit loans are usually cheaper than the development facility, because the build risk has gone. They can also release some of your profit early to put towards your next project. Lenders will want to see that the build is complete or close to it, plus evidence of sales values or rental demand. Our guide to development exit finance explains how it works in a slower market.

Our Process

Typical timing: Straightforward development finance cases can be completed in 12 to 18 weeks. It can be quicker where planning, costings and the professional team are all in place before you apply.

Same-Day Sense Check

Send us a quick outline including site address, GDV, loan amount, build costs, timescale, exit plan, and we will come back within 24 business hours with a clear plan and the likely structure of your loan.

DIP → Valuation → Offer

Once that is approved, we will request a signed Decision in Principle (DIP), from you and instruct the property valuation and set out any conditions in clear terms.

Legals & Completion

We keep the legal process moving and update you at every stage. If, for whatever reason, a date shifts, you’ll hear it from us first (along with a new date).

Development Finance FAQs

You apply with details of the site, your costings, the planning position and the end value. The lender sends a valuer and a monitoring surveyor to check the figures. Once the loan completes, the first payment usually goes towards buying the site, and the rest is released in stages as the monitoring surveyor signs off each stage of the build.

Interest is normally rolled up and added to the loan, and you repay everything when the units sell or you refinance onto a longer-term mortgage.

The usual fees are a valuation fee, legal fees and a lender application or arrangement fee to cover the costs of setting up the loan.


It is very important that you fully plan your project to avoid unnecessary fees.  If you decide to proceed with a property development loan through Clever Lending, we will also charge a fee (which will be discussed on application) and we can help you ensure you have the correct funds in place for the correct time period.

Due to the slight increase in risk with property development finance and the short-term nature, lenders charge slightly higher rates compared to a traditional mortgage.


Property Development finance interest rates are set by considering:

  • The value of the property or site
  • The size of the loan and total development costs
  • The loan-to-cost (LTC) and loan-to-gross development value (LTGDV)
  • The scale and complexity of the build
  • Your experience and track record


Property development loans are typically repaid in full at the end of the project, once the development has been completed.

If your sale or refinance takes longer than expected, lenders may allow an extension to the development loan, subject to review.


This will usually depend on:

  • How far the development has progressed
  • The reason for the delay
  • Updated valuations or sales evidence
  • Continued confidence in the exit strategy


Extensions can involve additional interest or fees, so the key is early communication and realistic planning from the outset. A well-structured development loan allows enough time and contingency to reduce the risk of pressure at the end of the project.

Yes. A number of UK lenders will fund first-time developers, and many assess the scheme more than your personal finances. They’ll look at the build costs and contingency, the planning position, the end value and how you plan to repay. Where you don’t have a track record, they’ll want related experience, such as a trade background, a buy to let portfolio or project management work, plus a credible main contractor and professional team.

Expect gearing to be a little lower than for experienced developers. Smaller schemes of one to four units and straightforward conversions are far easier to fund for a first project than a large ground-up site.

LTGDV stands for loan to gross development value. It’s the loan shown as a percentage of what the scheme will be worth once it’s finished. A £700,000 loan on a scheme with a GDV of £1 million is 70% LTGDV. Lenders use it alongside loan to cost to decide how much they’ll lend.

Clever Lending's panel funds senior development finance up to 70% Loan-to-GDV and 90% Loan-to-Cost, with most lenders requiring both ratios to be met. The right pairing depends on margin strength and the lender's appetite for the scheme. Mezzanine finance can lift overall gearing further by sitting behind the senior lender, usually at higher cost.
Funds are released in stages tied to build progress, certified by a monitoring surveyor at each milestone. Day-one funds usually cover land purchase. Subsequent drawdowns reimburse build costs as work is completed and signed off. You only pay interest on the funds drawn, not the full facility, which keeps interest costs proportional to your actual build spend.
Most development finance is structured with rolled-up interest, where interest accrues monthly, is added to the loan balance, and is then repaid at exit alongside the principal. That protects project cash flow during construction. Some lenders offer part-serviced options for experienced developers with rental income or other cash flow to call on. Rolled interest is included in the lender's day-one facility sizing.
The two standard exits are sale (selling completed units on the open market) and refinance (onto a buy-to-let mortgage, term loan or developer-exit bridge while the sales close out). Lenders want the exit identified at application, with sales-rate evidence (comparables, agent reports) or refinance terms (a DIP from the take-out lender). We sense-check the exit before submission.
Bridging is a single tranche drawn on day one and works best for light works, refurbishment or short-term holding. Development finance is staged drawdowns designed for ground-up construction or heavy conversions, with rolled interest and a longer facility. Heavy refurb (structural works, change of use) sits between the two and is sometimes funded by a dedicated refurb-bridge product.
Most senior development lenders require detailed planning consent to be in place before drawdown. A handful will fund site purchase pre-planning via a planning bridge, with the development finance refinancing once consent is granted. Permitted Development schemes can be funded once Prior Approval is in place. We sequence bridge-then-develop where planning timelines require it.
Lenders typically require 5 to 10% contingency built into the build budget, depending on project complexity, contractor experience and how fixed-price the build contract is. Older buildings, conversions and heavy refurb usually attract the higher end of the range. The contingency forms part of total project cost and is drawn down only when needed, signed off by the monitoring surveyor.
