Are Development Finance Projects Still Viable in 2026?

Development finance projects are still viable in 2026, but the margin for error can be smaller.

Higher property development costs, changing funding conditions and a subdued sales market mean assumptions that may once have looked comfortable can now require closer scrutiny. For brokers, this makes understanding the numbers behind a development increasingly important.

A strong site and experienced developer remain important, but development finance lenders also need to understand whether the project works financially, whether costs and values are realistic and how the loan will ultimately be repaid.

The question in 2026 is therefore not simply whether development finance is available. It is whether the individual project remains viable under realistic assumptions.

The Development Finance Market in 2026

The development market continues to face pressure in 2026.

The Bank of England reported in September that construction remained weak, particularly housebuilding, with continuing cost pressures and tighter funding conditions weighing on activity. Across the wider corporate lending market, it also reported increased competition for viable borrowers. For brokers, this reinforces the importance of assessing lender appetite for the individual development rather than assuming that broader credit availability translates into funding for every scheme.

Cost pressure has not disappeared either. Government construction-material statistics published in September showed that the material price index for all work was 5.9% higher in July 2026 than a year earlier.

For brokers, that distinction matters. Development finance in 2026 is not necessarily about lenders withdrawing from the market. It is about demonstrating that the individual scheme, borrower and exit make sense.

What Makes a Development Project Viable?

Development finance viability comes down to more than whether the finished properties should be worth more than the site and build costs.

Lenders will typically need to understand the complete project: the purchase or current site value, build costs, professional fees, contingency, timescale, planning position, expected gross development value (GDV), developer experience and proposed exit.

The amount of development finance required also needs to make sense in relation to the overall project.

A scheme with apparently attractive headline profit can become much tighter if construction takes longer than expected, costs increase or completed units achieve less than originally forecast.

That is why realistic assumptions are so important. A proposal should work based on credible figures rather than depending on everything going perfectly.

Have Build Costs and GDVs Been Realistically Assessed?

Two figures can fundamentally change the viability of a development: what it costs to complete and what it will ultimately be worth.

Property development costs should account for more than the headline construction contract. Professional fees, planning-related costs, utilities, finance costs, contingencies and potential delays can all affect the total requirement.

Current cost pressures make this particularly important. Official government data continues to show year-on-year increases in construction material prices.

The GDV needs equally careful consideration.

An optimistic gross development value (GDV) may make a proposal look attractive on paper, but the exit still depends on what buyers or refinancing lenders will realistically support when the development is completed.

The residential sales market has remained subdued during 2026. RICS reported in its July survey that buyer enquiries and agreed sales remained weak, although the pace of deterioration had eased.

For brokers, the useful question is therefore: what happens to the project if costs rise or the GDV comes in below expectations?

What Are Development Finance Lenders Looking For in 2026?

Development finance criteria vary between lenders, but the underlying assessment usually extends beyond the property itself.

Lenders may consider the developer’s experience and track record, planning status, project costs, proposed loan structure, GDV, expected profit margin, contingency and exit strategy.

Experience can be particularly important. A developer who has successfully delivered comparable projects may present a different risk profile from someone undertaking their first development.

That does not necessarily mean less experienced developers cannot obtain property development finance. However, the lender may want additional comfort around the professional team, contractor experience, project structure or borrower contribution.

Ultimately, development finance lending is about whether the lender is comfortable with both the project and the people responsible for delivering it.

Understanding these points before approaching the market can help brokers present a stronger case and identify lenders whose criteria are more closely aligned with the project.

What Can Make a Development Finance Application More Challenging?

A development finance application can become more difficult where there is uncertainty around one or more fundamental parts of the project.

Examples might include an unresolved planning position, limited developer experience, unrealistic build costs, insufficient contingency, an ambitious GDV or a weak exit strategy.

Complex site conditions, unusual construction methods or a development that is difficult to compare with surrounding schemes can also require more explanation.

The important point for brokers is to identify these issues before approaching development finance lenders.

A complicated case is not necessarily an unfinanceable one. But understanding where the complexity sits can make it easier to approach lenders whose appetite matches the project rather than submitting applications without knowing whether the scheme fits their criteria.

Is the Exit Strategy Still the Key to the Deal?

The development finance exit strategy remains fundamental because the lender needs a credible route to repayment.

For many developments, the exit will involve selling the completed units. In other cases, the developer may intend to refinance onto longer-term investment finance and retain some or all of the properties.

Either route needs to stand up to scrutiny.

If the strategy relies on sales, assumptions around achievable values and the expected sales period should be realistic. If refinancing is planned, the completed property, expected rental income, borrower and proposed loan will need to fit the anticipated longer-term lending criteria.

How Can Brokers Stress-Test a Development Finance Proposal?

Brokers do not need to become quantity surveyors or valuers to ask useful questions about a proposal.

Start with the assumptions.

What happens if build costs increase? Is there sufficient contingency? What happens if the project takes longer to complete? Would additional finance be required?

Then look at the exit. What happens if completed units take longer to sell or achieve a lower price than expected? If refinancing is the intended route, does the projected rental income and value support the anticipated borrowing?

Even modest changes can affect the numbers across a development.

FAQs

Is development finance still available in 2026?

Yes. Development finance lenders remain active, although appetite, leverage and development finance criteria vary. Lenders will assess the individual developer, project, costs, GDV and exit before deciding whether a proposal is suitable.

What is gross development value (GDV)?

Gross development value is the estimated value of a development once the project has been completed. It is an important part of assessing development finance viability and the amount a lender may be prepared to advance.

What costs should be included in a development finance proposal?

Alongside construction costs, a proposal may need to account for professional fees, planning-related expenses, utilities, finance costs, contingency and other project-specific expenditure. The exact costs will depend on the development.

Do development finance lenders require previous experience?

Experience is an important consideration for many lenders, but requirements differ. Where a developer has limited experience, lenders may consider factors such as the strength of the professional team, contractor experience, borrower contribution and overall project.

Why is the exit strategy important for development finance?

The exit explains how the development finance loan will be repaid. Common routes include selling completed units or refinancing onto longer-term finance. Lenders need to be comfortable that the proposed exit is realistic.

When should a broker consider specialist development finance?

Specialist development finance may be appropriate where a project is more complex, the borrower falls outside standard criteria or the funding structure requires greater flexibility. Speaking to a specialist early can help establish lender appetite before an application is submitted, improving the chances of the case being placed.
