Commercial Development Finance: Costs, Criteria and How to Apply

If you’re planning a commercial build, conversion, or refurbishment, commercial development finance can be a practical way to fund the project, because it’s designed around development milestones rather than a single upfront draw.

This guide explains what lenders typically want to see, how the funding is released, what costs to budget for, and how to prepare an application that stands up to scrutiny.

Commercial development finance

What is commercial development finance?

Commercial development finance is short-term borrowing used to fund the purchase of land or property and the costs of building or renovating a commercial scheme.

It’s commonly used for projects such as:

Retail units
Industrial units
Hospitality venues
Offices and mixed-use schemes
Schools and colleges
Care homes
Churches and community buildings
Residential developments for sale or rent (where the lender supports the risk profile)

It can be suitable for individuals, limited companies, LLPs, and other entities involved in property development.

How commercial development finance works (in plain English)

Most commercial development finance is structured to release funds in stages. Instead of receiving the full amount at the start, the lender typically releases tranches when agreed milestones are reached.

Common milestone triggers include:

Completion of site acquisition
Planning or pre-development steps
Start of works
Key build stages (for example, structural completion)
Practical completion and handover

Why staged drawdowns matter

Staged funding helps align the lender’s risk with the project’s progress. It also means you may only pay interest on the amount drawn at any point in time.

During the construction period, lenders may require updates and evidence of progress, and they may revisit valuations or assumptions if circumstances change.

The lender will expect an exit plan

Before agreeing to release funds, lenders usually want to understand how the development will be completed and how the loan will be repaid. Typical exit routes include:

Selling the completed units
Refinancing into a commercial mortgage
Long-term letting (where the lender supports the strategy)
partial sales with retention of remaining units (for example, holding some for rental income)

Costs to budget for: interest and fees

Commercial development finance often uses interest arrangements that differ from a standard monthly mortgage.

A common structure is interest rolled up, meaning interest is added to the loan balance and settled when the loan ends (for example, on completion, sale, or refinance).

Exact interest terms vary by lender and project, so it’s important to review the offer carefully and understand how interest and any fees interact over the term.

In addition to interest, development finance can involve several fees. These may include (depending on the lender and the deal):

Arrangement fees
Valuation fees
Legal fees
Exit fees
Non-utilisation fees (where applicable)
monitoring surveyor fees during construction
drawdown administration and reporting requirements

Non-utilisation fees

If a lender charges a non-utilisation fee, it’s usually intended to compensate them for funds that are reserved but not drawn. This is one reason your drawdown schedule and project programme matter.

Deposit and LTV considerations

Commercial development finance is usually assessed using the project’s total funding needs, which typically include:

Purchase costs (land or existing property)
Build and development costs

Purchase element

Many providers lend a proportion of the purchase price, which often means a deposit is required. The exact deposit and loan-to-value (LTV) can vary depending on the scheme, borrower strength, and the lender’s risk appetite.

Build element

For the build costs, lenders may lend a proportion of the development budget, often influenced by:

The strength of your business plan
The experience of the development team
The quality of the site and proposed works
The clarity of the exit strategy

In practice, the achievable loan-to-cost can range widely, so it’s worth preparing for lender-by-lender differences.

Key metrics lenders assess

Gross Development Value (GDV)

GDV is the expected market value of the completed development. Lenders use GDV to understand whether the project's end value can support repayment. GDV assumptions are usually supported by evidence such as comparable sales, appraisal methodology, and market testing.

Loan to Cost (LTC)

LTC compares the proposed borrowing against the total development cost. This includes professional fees and contingency. A lower LTC can indicate more borrower equity and may reduce lender risk, but the "right" level depends on the project type, location, and the credibility of the cost plan.

Loan to Value (LTV)

LTV compares the borrowing to the value of the asset. Depending on the stage of the project, this may refer to the land value or the value of an existing property. Where the project involves land already owned, LTV can influence how the facility is structured.

What lenders look for when deciding whether to lend

Commercial development finance is not only about the property, it’s about the likelihood of successful delivery and repayment.

While each lender has its own process, common requirements include:

A robust business plan

Your business plan is often the centrepiece of the application. Lenders typically expect:

A detailed schedule of works
A full cost breakdown (including professional fees and contingencies)
Evidence that the project is deliverable within the proposed timescales
A credible repayment strategy

If you have a track record of similar projects, highlight it clearly. If you’re a first-time developer, you may need to show additional support (for example, experienced consultants or a proven delivery team).

Planning and constraints

Many lenders will want to see the planning position before they commit to formal terms.

Full planning permission is often required before funds are released.
Some lenders may consider outline planning in principle, but they may still require full permission before drawdowns.

You should also be ready to explain any covenants, restrictions, or unusual planning conditions.

Site assessment and project viability

Lenders commonly assess the site and the development proposal to understand risk.

They may look at:

The suitability of the site for the proposed works
Access, servicing, and build feasibility
The quality of the contractor and delivery plan

Lenders usually take security over the site and may also require additional protections, such as:

conditions tied to planning progress and construction milestones
valuation reviews at key stages
monitoring of spend and progress
requirements around contractors and build programme

For schemes where the end product is primarily commercial, key considerations often include:

the expected rental or sale profile for the finished space
letting risk (if the plan involves leasing rather than immediate sale)
market demand and comparable evidence

Your financial position and structure

Lenders will review the borrower’s ability to manage the project and support the development if required.

They may consider:

Assets and liabilities
Existing commitments
Company structure and accounts (where relevant)

Some projects don't fit neatly into standard categories. Bespoke development finance may be used where the scheme is unusual in size, complexity, or structure.

Examples of why a bespoke approach may be considered include:

mixed-use or phased developments with different end products
complex refurbishment where costs and timelines are harder to predict
joint venture structures or alternative exit routes

In these cases, the facility terms may be tailored to reflect the project's specific risks and funding needs.

How to apply: a practical step-by-step checklist

Use the steps below to prepare an application that’s easier for a lender to assess.

Step 1: Define the project clearly

Be specific about what you’re building, where, and how you’ll deliver it. Include:

Property address and description
Scope of works
Target completion date

Step 2: Build a lender-ready business plan

Include a costed development appraisal and a schedule of works. Make sure it covers:

Purchase costs
Construction/build costs
Professional fees
Contingency allowance
Marketing and exit-related costs (if applicable)
planning and statutory costs
site preparation and remediation
certain holding costs, depending on the structure

Step 3: Prepare the documentation lenders usually request

While requirements vary, you should expect to gather items such as:

Business plan and development appraisal
Planning permission documentation (and any supporting evidence)
Details of your assets and liabilities
Information on any covenants or planning restrictions

Step 4: Align your drawdown plan with milestones

Your drawdown schedule should match the programme. If you’re likely to delay works, be realistic, because lenders may charge fees on undrawn amounts depending on the structure.

Step 5: Confirm your exit route

Before you apply, be clear on how the loan will be repaid.

Your exit plan should be consistent with the market assumptions in your business plan.

Step 6: Review the full offer details

When you receive terms, don’t focus only on the headline interest. Check:

How interest is calculated and when it’s payable
All fees and when they’re triggered
Any conditions tied to drawdowns

Which lenders offer commercial development finance?

Commercial development finance can be available from a range of providers, including specialist lenders and some mainstream banks.

In general:

Specialist providers may be more comfortable with development risk and bespoke structures.
Mainstream banks may be more selective, but can be competitive where the project fits their criteria.

There isn’t one universally “best” lender. Success often depends on matching the project to the lender’s assessment style and risk appetite.

Other alternatives to consider

A business loan may suit smaller projects where the funding need is limited and you don’t require the staged drawdown structure.

However, development finance is often more appropriate when you:

Need funding for land purchase and construction costs
Require staged releases aligned to build milestones
Are undertaking substantial works or refurbishment

Depending on your project size, timeline, and risk profile, you may also want to explore:

Bridging finance: typically a short-term facility where funds are released in one hit (useful for shorter timelines, but not always aligned with build-stage funding).
Mezzanine finance: often used to top up funding part-way through a project where there’s a gap between senior finance and total costs. This can increase overall cost due to the additional risk position.
Joint venture development finance: some structures involve profit share rather than a traditional deposit-led model, but they can come with higher cost and more complex agreements.

Can commercial development finance be used for an apartment building?

Yes, it can be possible. Lenders will focus on the strength of the proposal and the exit plan.

Apartment schemes can be assessed as higher risk in some cases, which may affect how lenders price the deal or how they structure the facility. The key is presenting a credible delivery plan and repayment strategy that matches the lender’s expectations.
