Development Finance Guide – Property Development Loans UK

Development finance is a specialist form of short-term property funding used to build, convert, refurbish, or redevelop property. It is usually used when a standard mortgage is not suitable because the project depends on future value, construction progress and a clear exit strategy.

This guide explains how development finance works, what lenders look for, how staged drawdowns are released, and when a property developer may need a specialist adviser. It is written for UK developers, investors, landlords, builders and property professionals who want to understand property development loans before speaking to a lender or broker.

If you are already planning a project, you can find a development finance adviser through Connect Experts.

Connect Experts is a mortgage adviser directory and matching platform. We do not provide mortgage advice directly. Advice is provided by the adviser or firm you choose.

What is Development Finance?

Development finance is a property loan designed to fund construction, conversion or major refurbishment projects. Unlike a standard mortgage, which is primarily based on the property’s current value and the borrower’s affordability, development finance is usually based on the project’s expected value upon completion.

That future value is called Gross Development Value, or GDV.

For example, a developer may buy land, obtain planning permission, build several homes and then repay the loan by selling the finished units. Another developer may convert a commercial building into flats and repay the loan by refinancing onto a longer-term mortgage once the development is complete.

Development finance is generally used when the work is too complex, too structural or too construction-led for a normal mortgage or simple bridging loan.

You may want to read the bridging loan guide if the project is mainly a short-term purchase, an auction purchase, a chain-break solution, or a light refurbishment.

How Does Development Finance Work?

Development finance is normally arranged around a development appraisal. This appraisal sets out the purchase price, build costs, professional fees, contingency, finance costs, expected sales values and projected profit.

The lender reviews the project before deciding whether the scheme is viable. If the lender agrees, the facility is usually structured in two parts:

  1. An initial advance
    This may help fund the purchase of the site or refinance existing borrowing.
  2. Staged drawdowns
    These help fund the build as work progresses. Drawdowns are normally released after inspections by a Quantity Surveyor or monitoring surveyor.


This staged structure helps control risk. It also means interest may apply only to the amount drawn, depending on the lender’s terms.

A specialist adviser can help present the project clearly to lenders. You can find a development finance adviser if you want support from someone experienced in this type of funding.

Development Finance vs Bridging Finance

Development finance and bridging finance are both short-term property funding options, but they are not the same.

QuestionDevelopment financeBridging finance
What is it mainly used for?Construction, conversion and heavy refurbishmentShort-term purchases, auction purchases, chain breaks and lighter works
How are funds released?Usually in stages as the build progressesOften as one initial advance
What does the lender assess?Current site value, GDV, build cost, planning and exitCurrent property value, security, exit and borrower profile
Is a Quantity Surveyor usually involved?Often yesNot always
Is it suitable for ground-up builds?Usually yesUsually no, unless very specialist
Is it suitable for light refurbishment?Sometimes, but often too specialistOften yes

If your project involves structural works, construction, conversion or a significant uplift in value, development finance may be more suitable. If your project is mainly a short-term purchase or light refurbishment, the bridging loan guide may be more relevant.

What Projects can Development Finance Fund?

Development finance can be suitable for a wide range of property projects, subject to lender criteria.

Ground-up residential developments

Development finance is often used for new-build houses, flats and small residential schemes. Lenders will usually assess planning permission, build costs, GDV, developer experience and projected demand.

Commercial developments

Commercial development finance can support projects involving offices, shops, industrial units, warehouses or other business premises. If the finished property will be used for business or investment purposes, the commercial mortgage guide may also be useful when considering the exit route.

Mixed-use and semi-commercial schemes

A mixed-use project may include both residential and commercial space, such as flats above a shop or a development with retail units and apartments. These schemes may require further assessment by specialist lenders. You may also want to read the semi-commercial mortgage guide.

Commercial to residential conversions

Development finance may be used where a commercial building is being converted into residential units. Lenders will review planning consent, permitted development rights where relevant, conversion costs, local demand and the intended exit strategy.

HMOs and multi-unit projects

Large HMO conversions and multi-unit refurbishments may suit development finance where the works are substantial. Smaller or less structural projects may be better suited to bridging finance.

Heavy refurbishments

Heavy refurbishment usually involves structural changes, extensions, change of use, reconfiguration or major works. Development finance may be appropriate where the project requires staged funding and monitoring.

Student accommodation and specialist residential schemes

Purpose-built student accommodation and specialist residential developments may qualify, depending on location, demand, planning and the exit strategy.

Light refurbishments

Light refurbishments are often better suited to bridging finance rather than development finance. Examples may include cosmetic improvements, new kitchens, new bathrooms or minor upgrades where the property is not being structurally changed.

Key Development Finance Terms Explained

Gross Development Value, or GDV

Gross Development Value is the estimated value of the completed development. It is one of the most important figures in a development finance application because lenders use it to assess the likely repayment position.

Loan to Gross Development Value, or LTGDV

Loan-to-Gross Development Value is the loan amount expressed as a percentage of the expected completed value. A lender may set a maximum LTGDV to limit risk.

Loan to Cost, or LTC

Loan-to-Cost compares the loan amount to the total project cost. Total costs may include land, construction costs, professional fees, financing costs, contingency, and other development expenses.

Gross Development Cost, or GDC

Gross Development Cost is the total expected cost of the project. It usually includes purchase price, build costs, professional fees, planning costs, legal costs, finance costs and contingency.

Drawdown

A drawdown is a release of funds from the lender. In development finance, drawdowns are usually staged and linked to progress in construction.

Quantity Surveyor, or QS

A Quantity Surveyor may be appointed to review costs, inspect the site, monitor progress and confirm whether the next drawdown should be released.

Rolled-up interest

Rolled-up interest is added to the loan and repaid at the end of the term, rather than paid monthly. This can help cash flow during the build, although it increases the final amount due.

Retained interest

Retained interest is interest deducted or held back from the facility at the start. It is used to cover interest during the loan term.

Exit strategy

An exit strategy explains how the loan will be repaid. Common exits include selling the completed units or refinancing into a longer-term mortgage.

Profit on cost and profit on GDV

Lenders want to see that the project has a sufficient profit margin to absorb delays, increased costs, or a softer sales market. A low profit margin can make a development finance application harder to place.

How Much Can You Borrow with Development Finance?

The amount you can borrow depends on the lender, project, location, developer experience, planning status, build costs and exit route.

Lenders may consider:

  • The current site value
  • The purchase price
  • The expected GDV
  • The total project cost
  • The developer’s cash contribution
  • The strength of the build schedule
  • The expected profit margin
  • The borrower’s experience
  • The professional team
  • The proposed exit strategy

Most lenders will not look at one figure in isolation. They may apply both LTGDV and LTC limits, then use the lower figure to manage risk.

For example, a lender may be comfortable with the GDV but reduce the loan if the developer has limited experience, weak cost evidence or an uncertain exit strategy.

This is why a detailed development appraisal matters. A strong appraisal helps the lender understand the numbers quickly and gives the adviser a better chance of matching the project with suitable lenders.

How Saged Drawdowns Work

Development finance is usually released in stages. This is different from a standard mortgage, where the loan may be released in a single amount upon completion.

A staged drawdown process may look like this:

  1. The lender agrees the overall facility.
  2. The initial advance is released.
  3. The developer starts or continues the build.
  4. The monitoring surveyor inspects the site.
  5. The surveyor confirms progress against the agreed schedule.
  6. The lender releases the next drawdown.
  7. The process repeats until the project is complete.
  8. The loan is repaid through sale or refinance.

Staged drawdowns protect both the lender and the borrower. They help ensure funds are released in line with progress and reduce the risk of money being used before it is needed.

Documents Usually Needed for Development Finance

A development finance adviser may ask for documents such as:

  • Development appraisal
  • Planning permission documents
  • Site address and title information
  • Purchase contract, if applicable
  • Build cost schedule
  • Schedule of works
  • Architect drawings
  • Details of the main contractor
  • Details of the professional team
  • GDV evidence and comparable sales
  • Asset and liability statement
  • Proof of deposit or cash contribution
  • Company accounts, if applicable
  • Experience summary or previous project evidence
  • Exit strategy
  • Timeline for the works
  • Details of any existing borrowing

Providing documents early can reduce delays and help advisers approach suitable lenders more effectively.

What Lenders Look for in a Development Finance Application

A strong development finance application should be clear, realistic and supported by evidence.

1. A realistic Gross Development Value

The GDV should be supported by recent and relevant comparable evidence. Lenders will not rely only on optimistic sales expectations.

2. A detailed cost schedule

The build cost schedule should include labour, materials, professional fees, contingency, planning costs and other expected expenses. It should be realistic and, where possible, professionally prepared.

3. Planning permission

Many lenders prefer full planning permission before funds are released. Some specialist lenders may consider earlier-stage projects, but this usually depends on risk, location and borrower experience.

4. Developer experience

Experienced developers may have more lender options. First-time developers may still be considered, but lenders may want a stronger professional team, a larger cash contribution, or an experienced contractor.

5. A strong professional team

Lenders may review the builder, architect, solicitor, planning consultant, project manager and Quantity Surveyor. A credible team can improve lender confidence.

6. A clear exit strategy

The lender needs to understand how the loan will be repaid. The exit should be realistic and supported by market evidence.

7. Suitable contingency

A contingency allowance helps protect against unexpected costs. Without a sensible contingency, lenders may question whether the scheme can be completed if prices rise or delays occur.

8. Evidence of demand

Lenders want to know that the completed units can be sold or refinanced as expected. Local demand, comparable sales and rental evidence may be important.

Development Finance Costs

Development finance costs vary depending on the lender, project and risk profile. Common costs may include:

  • Arrangement fee
  • Interest
  • Valuation fee
  • Quantity Surveyor or monitoring surveyor fee
  • Legal fees
  • Exit fee, where applicable
  • Broker fee, where applicable
  • Drawdown fees, where applicable
  • Administration fees
  • Planning or professional fees
  • Contingency allowance
  • Insurance and warranty costs


Interest may be rolled up, retained or serviced monthly. The right structure depends on cash flow, lender criteria and the planned exit.

Before proceeding, ask your adviser to explain the full cost of borrowing, not only the headline interest rate

Example Development Finance Scenario

A developer plans to buy a site and build four residential units.

ItemExample figure
Site purchase£500,000
Build costs£700,000
Professional fees and contingency£150,000
Total project cost£1,350,000
Expected GDV£1,800,000
Expected profit before finance costs£450,000

A lender would review the total cost, expected GDV, planning permission, build schedule, developer experience and exit strategy. The lender may then apply its maximum LTGDV and LTC limits.

If the figures work, the lender may provide an initial advance towards the site purchase and staged drawdowns during construction. The loan could then be repaid when the completed units are sold or refinanced.

This example is for illustration only. Actual lending depends on the lender’s criteria, project risk, and individual circumstances.

Can first-time developers get development finance?

First-time developers may be able to access development finance, but lender criteria can be stricter. Lenders may want to see a strong professional team, a realistic appraisal, a higher cash contribution and a clear exit.

A first-time developer may improve their application by showing:

  • Relevant construction, property or project management experience
  • A qualified builder or contractor
  • Detailed costings
  • Full planning permission
  • Strong comparable evidence
  • A realistic timeline
  • A sensible contingency
  • A clear repayment route


If you are new to development finance, it may help to speak to an adviser before approaching lenders directly. A specialist adviser can explain what lenders may expect and how to present the project.

Exit strategies for development finance

An exit strategy is one of the most important parts of a development finance application. It explains how the loan will be repaid.

Common exit strategies include:

Sale of completed units

The developer sells the finished houses, flats or commercial units and repays the facility from sale proceeds.

Refinance onto a longer-term mortgage

The developer keeps the completed property and refinances it onto a longer-term product, such as a buy-to-let mortgage, commercial mortgage or semi-commercial mortgage.

If the completed property will be used for business purposes, read the commercial mortgage guide. If it includes both commercial and residential elements, read the semi-commercial mortgage guide.

Sale of the site

In some cases, a developer may sell the site with planning or part-completed works, although this may be a less common or higher-risk exit.

A lender will want the exit to be realistic. If the exit depends on refinancing, the lender may assess whether the completed development is likely to meet refinance criteria.

Common development finance mistakes to avoid

Avoid these common issues before applying:

  • Overstating the GDV
  • Underestimating build costs
  • Leaving out professional fees
  • Using weak comparable evidence
  • Ignoring contingency
  • Assuming all lenders use the same criteria
  • Applying before planning is clear
  • Failing to provide evidence of experience
  • Choosing an unrealistic build timeline
  • Relying on a vague exit strategy
  • Confusing development finance with bridging finance

A well-prepared application gives lenders more confidence and may improve the chance of suitable terms.

Why Use a Development Finance Adviser?

Development finance is specialist lending. Lenders may differ significantly in how they assess GDV, build costs, developer experience, planning status, location, property type and exit strategy.

A development finance adviser can help you:

  • Understand whether development finance is suitable
  • Prepare your proposal for lenders
  • Compare potential lender options
  • Identify likely issues before submission
  • Understand key terms and fees
  • Structure the facility around the build
  • Plan the exit strategy
  • Reduce avoidable delays

When Development Finance may not be Suitable

Development finance may not be suitable if:

  • The project is only a light refurbishment
  • The exit strategy is unclear
  • Planning permission is uncertain
  • The GDV is not supported by evidence
  • The project has a weak profit margin
  • The borrower cannot provide enough contribution
  • The build costs are not realistic
  • The borrower does not have a suitable professional team

In some cases, bridging finance, a commercial mortgage, a semi-commercial mortgage or another funding route may be more appropriate.

Read the bridging loan guide, commercial mortgage guide or semi-commercial mortgage guide if your project sits outside a standard development finance structure.
