Commercial Property Development Finance: 2026 Market Outlook

Building a commercial scheme ties up cash for a long time before a single tenant moves in or a single unit sells. Land has to be bought, drawings paid for, contractors invoiced month after month, and none of that turns into value you can bank until the building is finished and let or sold. Commercial property development finance exists to bridge that gap, and getting the structure right at the outset decides whether a scheme runs smoothly or runs out of money halfway up. We arrange this funding every week, and this piece sets out how it works in the 2026 market.

In plain terms, commercial property development finance is short-dated, drawdown lending that funds the land purchase and the construction of a commercial building through to practical completion and exit. It is released in stages against work done on site, the interest is usually rolled up rather than paid monthly, and it is repaid in one go when the scheme is sold or refinanced onto longer-term debt. It is not a mortgage on a finished, income-producing asset. It is money against a plan, a cost schedule and an end value that does not yet exist.

This article covers what the product is, how a lender works out the maximum facility, the full product ladder from senior debt up to joint venture equity, the leverage you can reach on each rung, the sectors it spans, and a short view on the next twelve months. One point up front: we are an arranger and introducer, not a lender. We place schemes with the right funders rather than lending our own money, we are not authorised by the FCA, and the lending we arrange is unregulated commercial lending. Every figure below is indicative market commentary for UK property in 2026, never an offer of finance.

The 2026 market backdrop

The Bank of England base rate sits at 3.75%, held there since the December 2025 cut, which was the fourth reduction of 2025. That matters to developers for two reasons. First, short-dated and bridging-style debt prices off SONIA, which tracks the base rate closely, so the cost of the money you borrow during construction is anchored to where the Bank has settled. Second, a lower and steadier rate environment tends to support end values, because the investors and owner-occupiers who buy your finished building borrow off the same curve.

Against that backdrop, senior development finance is pricing indicatively at 9 to 12% per annum in 2026, with short-dated bridging-style facilities at roughly 0.65 to 1.0% per month. Arrangement fees typically run at 1 to 2% of the loan. None of these are fixed: pricing moves with the strength of the scheme, the experience of the borrower, the sector and the exit. They are the bands we are seeing across the market right now, and they give you a realistic starting point for an appraisal.

How a lender sizes a development facility

There are two tests, and the maximum facility is the lower of the two. The first is loan to cost, or LTC, which is the loan measured against the total cost of the project, including land, build, professional fees and finance costs. Senior lenders are indicatively comfortable at 65 to 70% of cost. The second is loan to gross development value, or LTGDV, which measures the loan against the finished, completed value of the scheme. Senior LTGDV sits indicatively at 60 to 65%.

The lender runs both and lends the smaller number. Take a scheme with a £3m gross development value and £2.2m of total cost. Senior at 70% of cost gives £1.54m. The same scheme capped at 65% of GDV gives £1.95m. The lower of the two is £1.54m, so that is the maximum senior facility, and the remaining cost is day-one equity the developer puts in first. On this scheme the cost test bites before the value test does, which is common where the margin between cost and value is tight. Get the appraisal wrong on either line and the facility you were counting on shrinks.

It is also worth knowing how the interest is handled. It can be retained, meaning deducted up front and held by the lender, or serviced, meaning paid monthly out of your own cash. Most ground-up schemes roll the interest up, and that rolled-up interest sits inside the loan to cost from day one. So when you model 70% LTC, the interest is already eating into your headroom before the first brick is laid.

A development lender sizes on the lower of loan to cost and loan to GDV, and every rung of the leverage ladder above senior is bought with a higher cost of capital.

The product ladder

Development finance is not a single product. It is a stack, and you climb it when senior debt alone does not stretch far enough to fund the scheme against the equity you have.

Senior development finance is the base layer, sitting first in line for repayment at 65 to 70% of cost and 9 to 12% per annum. Stretched senior pushes the same single facility up to 75 to 80% of cost at a blended rate above standard senior, which suits developers who want one lender and one set of terms but need more gearing. Mezzanine finance sits behind the senior loan and fills the gap above it, taking combined leverage to 85 to 90% of cost in exchange for a higher return, because it is repaid after the senior debt and carries more risk. Above that, JV equity partners and family offices can take a scheme to as much as 100% funded, but they price on a share of the profit rather than a rate, so you give up upside instead of paying interest.

Two further products sit at the back end of the lifecycle rather than the build. Development exit finance refinances a completed or near-complete scheme onto cheaper, longer terms, which buys a developer time to sell or let without the original facility expiring. Stabilisation finance does a similar job for a finished building that is still filling up with tenants, holding the asset until it reaches the income level a long-term lender wants to see. Permitted development finance funds conversion schemes that use PD rights rather than a full planning consent. The point of the ladder is simple: more leverage is available, and each rung is bought with a higher cost of capital.

Which lender camps fund it

We place schemes across the whole funder market rather than with any single name, because the right home for a deal depends on its size, sector and risk. Specialist development lenders are the workhorses for ground-up schemes and move quickly on build risk. Challenger banks compete hard on senior debt for stronger sponsors with a track record. Senior, clearing and insurance-backed banks offer the keenest pricing but ask for the most cover and the cleanest schemes. Real estate debt funds bring flexible senior and stretched senior money where a bank will not go. Mezzanine providers fill the gap above the senior loan, and JV equity partners and family offices come in where a scheme needs equity rather than debt. Matching the scheme to the right camp is most of the job.

How we approach a development finance scheme

We start with the appraisal, not the lender. Before we approach anyone we pressure-test the costs, the programme, the gross development value and the exit, because that is what every funder will do and it is better to find the weak line ourselves. We work out where the scheme sizes on both loan to cost and loan to GDV, confirm the day-one equity the developer needs to commit, and decide whether senior alone funds it or whether it needs stretched senior, a mezzanine layer or equity to complete the stack. Then we take it to the camps most likely to back it, on terms that reflect the strength of the deal rather than a headline rate.

Cross-sector by design

Commercial property development finance is not limited to one building type. We arrange it across offices, warehouses, logistics, PBSA and student accommodation, care homes, retail, hotels, leisure, industrial, mixed-use, self-storage, data centres, life sciences, build to rent and wider healthcare. Each sector carries its own appetite, its own view on end value and its own preferred funders, which is exactly why matching the scheme to the right camp matters so much.

The next twelve months

With base rate held at 3.75% and the market expecting stability rather than sharp moves, we expect development pricing to stay broadly where it is through the second half of 2026, with the strongest schemes and most experienced sponsors continuing to win the keenest terms. Appetite for logistics, build to rent, student accommodation, data centres and life sciences remains firm, while secondary retail and older offices face more questions on exit. Stable funding costs make appraisals easier to underwrite, and that tends to bring more lenders to the table. The developers who do best will be the ones who size their schemes honestly against both tests and line up the right layer of the ladder before they need the money.

FAQ

Are you a lender? No. We are an arranger and introducer. We place schemes with development funders rather than lending our own money. We are not authorised by the FCA, and the lending we arrange is unregulated commercial lending.

What is the maximum I can borrow on a development scheme? The facility is the lower of two tests: loan to cost, indicatively 65 to 70%, and loan to GDV, indicatively 60 to 65%. The lender runs both and lends the smaller figure, with the rest being your day-one equity.

What does development finance cost in 2026? Senior development finance is pricing indicatively at 9 to 12% per annum, short-dated bridging-style facilities at 0.65 to 1.0% per month, with arrangement fees of 1 to 2% of the loan. These are indicative bands, not an offer.

Do I pay the interest monthly? Usually not. On most ground-up schemes interest is rolled up and sits inside the loan to cost from day one. It can also be retained up front or serviced monthly, depending on the structure and the lender.
