Developer finance, often called development finance, is short-term secured funding used to buy land or property and pay for construction, conversion or major refurbishment works. It is normally repaid when the finished project is sold, refinanced or repaid from another agreed source.

It is not just a larger version of a normal mortgage. A development lender will usually look closely at the project itself: the planning position, build costs, professional team, borrower contribution, experience, gross development value, cash flow and exit strategy.

This guide is for general information only and is not personal mortgage advice. Your options depend on your circumstances, the site or property, lender criteria, the proposed works and the route for repaying the borrowing.

What does developer finance mean in practice?

Developer finance is usually used where a property project involves building, converting or substantially changing a site before it can be sold, let or refinanced.

In practice, it may fund:

• buying a plot of land with planning permission
• building one or more new properties
• converting a commercial building into residential units
• completing a part-built development
• carrying out heavy refurbishment before sale or refinance
• funding construction costs on a site you already own
• buying a property that is not currently suitable for a standard mortgage because of its condition or use

The loan is usually secured against the site or property. Instead of releasing all the money at once, a lender may provide an initial amount for the purchase or refinance, then release further funds in stages as the build progresses.

Those staged releases are important. They mean your cash flow needs to be planned carefully, because you may need to pay for some work before the next drawdown is approved.

How is developer finance different from a mortgage or bridging loan?

The right route depends on the property, the works and the exit plan. The table below gives a simple comparison.

For straightforward homebuyers, a normal mortgage route is usually more relevant. public guidance explains the basics of mortgages, deposits, repayments and budgeting for homebuyers here: public guidance buying a home.

GOV.UK also sets out the standard home-buying process, including preparing to buy, arranging finance, surveys and conveyancing: GOV.UK buying a home.

Developer finance becomes more relevant when the lender has to assess build risk, planning risk, staged costs and how the finished project will repay the debt.

Who is developer finance relevant for?

Developer finance may be relevant for:

• experienced property developers
• landlords moving into heavier refurbishment or conversion projects
• limited company property investors
• builders or property professionals developing a site
• borrowers buying land with planning permission
• owners of a site who need funds to build or complete works
• investors converting property for sale or refinance
• first-time developers with a strong professional team and realistic figures

It may be less suitable if:

• you are buying a standard home to live in
• the property only needs light decoration
• you want a long-term repayment mortgage from day one
• you do not have a clear exit route
• the planning position is uncertain
• you cannot evidence the build costs
• your figures rely on optimistic resale or rental assumptions

If you are unsure whether the case is a mortgage, bridging or development finance case, it is worth checking before you apply. Applying to the wrong type of lender can waste time and may create avoidable problems.

How does development finance work step by step?

A typical development finance process may look like this:

The lender will usually want to understand not only whether the numbers work today, but also what happens if costs rise, the build takes longer or the sale/refinance takes more time than expected.

Can you get 100% development finance?

Some borrowers search for 100% development finance, but it is important to be precise about what that means.

In many cases, lenders expect the borrower to put in cash, land equity or another acceptable contribution. A lender may talk about funding a high proportion of build costs, but that does not necessarily mean funding 100% of the whole project with no borrower contribution.

There are three different ideas that are often confused:

If a project is advertised or discussed as “100% funded”, ask what is actually included:

• land purchase
• build costs
• professional fees
• planning costs
• valuation and monitoring costs
• legal fees
• interest
• contingency
• exit fees, if any
• VAT or tax-related costs, where relevant

Do not assume a headline funding percentage tells you whether the project is viable. The total cost, cash flow and exit route matter more.

A common trap: confusing “funding the build” with funding the whole project

A landlord buying a tired mixed-use building might be told the works could be funded in stages once planning is in place. On paper, the project looks simple: buy the property, convert the upper floors into flats, refurbish the ground floor, then refinance when the units are lettable.

The problem is that the headline funding figure may not cover the cash needed at the points it is actually needed. The first release might help with the purchase, but the next drawdown may only come after a monitoring surveyor confirms enough work has been completed. That can leave the borrower having to pay contractors, materials, professional fees and VAT before the next tranche is available.

A lender would also look beyond the build budget. If the exit is a buy-to-let refinance, the finished property still needs to meet the future lender’s criteria. That may include lease structure, planning sign-off, building control, warranties, rental evidence, valuation and whether the commercial element affects appetite.

Practical lessons:

• do not rely on the phrase “100% of build costs” without mapping the full cash flow
• include professional fees, monitoring fees, legal costs, interest and contingency
• check when each drawdown is released, not just the total facility size
• make sure the refinance exit is realistic for the finished property, not just assumed
• keep a fallback plan if costs rise, completion slips or the valuation is lower than expected

This is where developer finance differs sharply from a standard mortgage: the timing of money can matter as much as the amount available.

What might lenders assess?

Development lenders usually assess both the borrower and the project. The exact criteria vary, but the key areas are often similar.

The borrower

A lender may consider:

• development experience
• credit history
• assets and liabilities
• borrower contribution or equity
• income and wider financial position
• professional background
• previous projects, where relevant
• whether the borrowing is personal, limited company or another structure

A first-time developer may still have options, but the lender may want stronger evidence around the professional team, contingency, project management and exit plan.

The site or property

The lender will usually look at:

• location
• current use
• title
• condition
• access and services
• planning status
• valuation
• existing charges or restrictions
• whether the property is suitable security

A site with full planning permission is not the same as a site where planning has not yet been granted. Planning risk can change the lender’s view of the case, the amount available and the structure of the facility.

The works

The lender will want to understand the scope of the build or refurbishment. This may include:

• schedule of works
• drawings and specifications
• build cost breakdown
• contractor details
• fixed-price contract or cost estimate
• professional team
• timescale
• building control position
• warranty position, where relevant
• contingency allowance

Underestimating costs is one of the most common ways a viable-looking project becomes difficult. If the facility is based on unrealistic figures, the project may run out of money before completion.

The numbers

Lenders commonly review:

• purchase price or existing site value
• current value
• build cost
• professional fees
• finance costs
• contingency
• gross development value, often called GDV
• borrower contribution
• projected profit margin
• loan-to-cost position
• loan-to-value or loan-to-GDV position
• expected sale or refinance values

A lender is effectively asking: does the project still make sense if costs rise, values change, the build is delayed or the exit takes longer?

The exit route

The exit route is one of the most important parts of the application.

Common exits include:

• selling the completed property or units
• refinancing onto a buy-to-let mortgage
• refinancing onto a commercial mortgage
• refinancing onto a residential mortgage, where appropriate
• using another agreed source of funds

If the exit is refinance, the lender may want to understand whether the finished property is likely to meet the future lender’s criteria. If the exit is sale, they may look at likely demand, comparable sales and the expected sales period.

The Financial Conduct Authority sets the conduct framework for regulated mortgage activity and consumer protection. You can read more here: FCA consumers and FCA mortgage rule review.

Not all development finance is regulated mortgage business. The position depends on the borrower, property use and structure of the borrowing, so it should be checked rather than assumed.

What documents make a developer finance enquiry easier?

You do not always need every document on day one, but the more complete the information, the easier it is to assess the case properly.

A short project summary can also help. It should cover what you are buying or developing, what works are required, how much they cost, how the funds will be released, and how the loan will be repaid.

What can make developer finance harder?

Development finance can become harder where there is uncertainty around the project or exit.

Common issues include:

• no planning permission where the project depends on consent
• unclear or unresolved planning conditions
• unrealistic build costs
• no contingency
• weak or missing contractor information
• limited borrower contribution
• poor credit history without a clear explanation
• no previous development experience and no strong professional team
• uncertain end value
• weak evidence for expected sale or rental demand
• unclear exit route
• tight deadlines that do not allow for valuation, legal work and due diligence
• title, access, lease or legal issues affecting the security

The wider interest-rate environment can also affect borrowing costs and lender appetite. The Bank of England explains the Bank Rate here: Bank of England Bank Rate. Individual development finance pricing still depends on the lender, project risk, borrower profile and facility structure.

Which mistakes cause the biggest problems?

Treating it like a normal mortgage

A standard mortgage usually focuses heavily on personal affordability and whether the property is acceptable security. Development finance is different because the project itself is central.

If you approach it like a normal mortgage application, you may miss the information the lender needs most.

Relying on a weak exit route

A lender will usually want a credible repayment route before agreeing the facility. “We will sell when finished” may not be enough if the projected value, demand, timescale and fallback plan have not been considered.

Underestimating total cost

Development projects can involve more than the purchase price and build cost. Potential costs may include:

• arrangement fees
• valuation fees
• monitoring surveyor fees
• legal fees
• planning costs
• professional fees
• insurance
• warranty costs
• contingency
• interest
• broker fees, where applicable
• exit fees, if charged

Not every fee applies in every case, but the full cost should be modelled before you commit.

Ignoring cash flow

Even if a lender agrees to fund part of the project, money may be released in stages. You need to know what must be paid before each drawdown and what happens if the next drawdown is delayed or reduced.

A project can look profitable on paper but still run into trouble if cash flow is too tight.

Applying to the wrong lender

Some lenders prefer experienced developers. Some consider smaller schemes. Some are more comfortable with certain property types, regions, planning positions or exit routes.

The value of advice is often in knowing where not to apply, as well as where to apply.

What could developer finance look like in practice?

Example 1: Buying a plot with planning permission

A borrower wants to buy a small plot with planning permission to build one residential property. They need funding for the land purchase and staged build costs.

A lender may look at:

• purchase price of the plot
• planning permission and conditions
• build cost estimate
• borrower contribution
• builder or contractor details
• projected completed value
• contingency
• exit route, such as sale or refinance

If the borrower has limited development experience, the lender may place more weight on the builder, professional team, contingency and project management.

Example 2: Converting a commercial property

A borrower wants to convert a small commercial property into residential units.

A lender may focus on:

• current use of the property
• planning status
• conversion costs
• professional reports
• expected completed value
• demand for the finished units
• borrower experience
• route to repay the loan

This may be more complex than a simple refurbishment because the lender needs comfort around planning, building control, conversion risk and exit.

Example 3: Heavy refurbishment before refinance

A landlord owns a property that needs significant work before it can be let or refinanced. The plan is to carry out the works, then refinance onto a buy-to-let mortgage.

A lender may ask:

• is the property currently mortgageable?
• what works are needed?
• how much will the works cost?
• what rent is expected after completion?
• will the finished property meet buy-to-let lender criteria?
• what happens if refinance is delayed?

Depending on the scale of works, this could sit between bridging finance and development finance.

Example 4: First-time developer with a strong team

A borrower has not completed a development before but has found a viable project and appointed experienced professionals.

A lender may still consider the case, but may want stronger evidence around:

• project management
• contractor experience
• contingency
• borrower contribution
• professional oversight
• realistic exit assumptions

First-time development does not automatically mean there are no options, but the case usually needs to be prepared carefully.

Is developer finance always the right route?

No. The right route depends on the works, the property condition, timing and exit.

The key is not to chase a label. It is to match the finance to the project risk, timescale and repayment route.

What should you prepare before asking for help?

Before speaking to a broker or lender, prepare a short summary covering:

• the site or property address
• whether you own it already or are buying it
• purchase price or current value
• planning status
• what you intend to build or change
• estimated build cost
• professional team involved
• your contribution or equity
• expected completed value
• intended sale price or refinance route
• expected timescale
• your development experience
• any credit or income issues that may need explaining
• hard deadlines, such as auction completion or contract dates

Also think about your fallback plan. What happens if the valuation is lower than expected, the works cost more, the build takes longer or the refinance route is not available at the point you need it?

When should you speak to a broker?

It is sensible to speak to a broker before applying if:

• you are buying land or a property to develop
• the property is not currently mortgageable
• you need staged funding
• planning permission is involved
• you intend to convert the property
• you are relying on sale or refinance as the exit
• you are borrowing through a limited company
• you are unsure whether you need bridging, development finance or a mortgage
• your credit profile or income is not straightforward
• the timescale is tight

We can help you understand how lenders may view the case before you commit to an application. That does not mean funding is guaranteed. It means we can help you prepare the right information, identify suitable routes and avoid approaches that are unlikely to fit the project.

FAQs

What is developer finance?

Developer finance is short-term secured funding used for property development, such as building, conversion or heavy refurbishment. It is usually repaid by selling the finished property, refinancing it or using another agreed exit route.

Is developer finance the same as development finance?

In UK property finance, the terms are often used to mean broadly the same thing. Some people say developer finance, while lenders and brokers commonly use development finance.

How long does development finance usually last?

It is usually short-term finance. The exact term depends on the lender, project and exit route. The term should allow enough time for the build, any sales or refinance process, and a sensible contingency.

Do you need planning permission for development finance?

Not always, but planning status is a major factor. A site with full planning permission is usually viewed differently from a site where permission has not yet been granted. If the project depends on planning consent, the lender will want to understand that risk.

Can first-time developers get development finance?

Some lenders may consider first-time developers, but they may want stronger evidence of a realistic project, borrower contribution, professional support, contractor experience, contingency and exit route.

Is development finance regulated?

Some property finance is regulated and some is not. It depends on the borrower, property use and loan structure. If the finance relates to a home you live in or intend to live in, regulated mortgage advice may be relevant.

Is developer finance expensive?

It can be more expensive than mainstream residential borrowing because it is short-term, specialist and project-based. The total cost can include interest, arrangement fees, valuation fees, legal fees, monitoring fees and possible exit fees.

What is GDV?

GDV means gross development value. It is the expected value of the completed project. Lenders often use it when assessing how much they may be prepared to lend and whether the project looks commercially viable.

What is the most important part of a development finance application?

There is no single factor, but lenders usually pay close attention to the planning position, build costs, borrower contribution, experience, GDV, cash flow and exit route. Weakness in one area may need to be balanced by strength elsewhere.
