Stretched Senior Development Finance 2026: Higher Leverage From One Facility

Most developers we speak to want the same two things at once: more leverage on the scheme, and less complexity to get there. Plain senior development finance keeps the loan conservative, usually 65 to 70% of cost, which means you carry a large slug of your own equity into the build. The classic way to push leverage higher is to bolt a separate mezzanine tranche on top of the senior loan, but that brings a second lender, a second set of terms, and an intercreditor agreement to negotiate between them. There is a middle option that solves both problems at once.

That option is stretched senior development finance: a single facility set at a higher leverage point, typically 75 to 80% of cost, from one lender on one legal charge. People also call it stretch senior. The point of stretched senior development finance is that you get more of the capital stack covered by debt than plain senior gives you, but you do it inside one loan rather than stacking two lenders. There is no mezzanine provider sitting behind the senior, and so there is no intercreditor agreement to argue over. One facility, one lender, one charge, one set of terms.

This article explains what stretched senior is, how it differs from plain senior and from a senior-plus-mezzanine stack, why the rate sits where it does, who it suits, and which lender camps tend to write it. A quick note on who we are first: we are a finance arranger and introducer, not a lender, and we are not FCA authorised because commercial development lending of this kind is unregulated. Everything below is indicative market commentary for UK property in 2026, not an offer, and every figure is a guide to where the market sits, not a quote. The Bank of England base rate has been held at 3.75% since the December 2025 cut, which is the backdrop for the pricing we describe.

What stretched senior development finance actually is

Stretched senior is a development loan that goes to a higher leverage point than a normal senior facility, while staying as a single facility. Where plain senior tends to cap out around 65 to 70% of total project cost, stretched senior reaches 75 to 80% of cost. The lender takes a first legal charge over the site and funds the land purchase and the build costs in stages, just as a senior lender does, but it is willing to advance a larger share of the cost from its own book.

The simplest way to picture it is as senior debt that has been pushed up the capital stack to a point a mezzanine lender would normally occupy, but without bringing that second lender into the deal. The single lender absorbs the extra risk of the higher leverage itself and prices for it, rather than letting a junior lender take that slice on separate terms. For the developer, the experience is the same as a senior facility: one relationship, one drawdown schedule, one set of monitoring surveyor reports, one redemption at the end.

How it differs from plain senior

The headline difference is leverage. Plain senior at 65 to 70% of cost leaves you funding 30 to 35% of the scheme yourself, plus whatever the loan to GDV cap holds back. Stretched senior at 75 to 80% of cost cuts the equity you put in to roughly 20 to 25% of cost before any GDV cap bites. On a scheme where your own cash is the constraint, that difference decides whether you can do one project or two.

The second difference is price. Senior development finance currently runs at about 9 to 12% per annum. Stretched senior is priced as a blended rate that sits above that senior range, because the lender is carrying more of the cost and therefore more risk for the same security. You are paying for the extra leverage in the rate. The arrangement fee is broadly similar to senior, in the region of 1 to 2% of the loan. So the trade is straightforward: you commit less of your own equity and keep the deal simple, and in return your blended cost of capital is higher than it would be on a conservative senior loan.

Stretched senior versus senior plus mezzanine

This is the comparison that matters most, because stretched senior and a senior-plus-mezzanine stack are aiming at a similar leverage outcome by different routes.

A senior-plus-mezzanine structure layers two facilities. A senior lender provides the bulk of the debt, and a separate mezzanine lender provides a junior tranche behind it, taking the leverage up to around 85 to 90% of cost. Because there are two lenders with claims over the same scheme, they sign an intercreditor agreement that sets out who gets paid first, who can enforce, and what each can do if the project drifts. That agreement takes time and legal cost to put in place, and it adds a second credit process to clear before you can draw.

Stretched senior collapses that into one facility. There is no junior lender, so there is no intercreditor agreement, no second legal team, and no second credit committee. The leverage is lower than a full senior-plus-mezzanine stack, 75 to 80% rather than 85 to 90% of cost, but it gets there faster and with far less moving machinery. If you need to reach the top of the stack at 85 to 90%, you still need mezzanine. If 75 to 80% is enough and you value speed and simplicity, stretched senior usually wins on both.

It helps to see the whole leverage ladder in order. Plain senior sits at 65 to 70% of cost. Stretched senior sits at 75 to 80%. Senior plus mezzanine reaches 85 to 90%. JV equity can go up to 100% for the right scheme and sponsor. Stretched senior is one rung up from senior, delivered without the complexity of the rung above it.

Sizing is still capped by the lower of LTC and LTGDV

A point that catches developers out: the 75 to 80% of cost figure is a ceiling, not a promise. Every development facility is sized on the lower of two tests, loan to cost and loan to gross development value, and the loan is set by whichever test produces the smaller number.

The loan to GDV cap typically sits at 60 to 65% of the finished value of the scheme. On a project with a healthy margin, where costs are modest relative to end value, the loan to cost test will usually be the binding one, and stretched senior can run up toward that 75 to 80% of cost. On a tighter scheme, where costs are high relative to the GDV, the loan to GDV test bites first and holds the loan below the cost-based figure regardless of how high the lender will stretch on cost. So stretched senior raises the loan to cost ceiling, but it does not move the loan to GDV cap. You still need the end value to support the debt.

Which lender camps fund it

Stretched senior is written by a particular set of lenders rather than the whole market. Speaking generically, and without naming anyone, the camps that tend to offer it are the specialist development lenders and debt funds that hold their own capital and set their own credit appetite, which lets them sit higher up the stack on a single charge. Some of the larger challenger and private lenders also have a stretched product alongside their standard senior line. Mainstream high street banks generally stay at conservative senior leverage and do not stretch, which is one reason developers come to the specialist end of the market for it. The right camp for a given scheme depends on the asset type, the location, the sponsor’s track record, and the size of the loan, which is the part we help match.

How we approach a stretched senior facility

We start with the numbers that decide whether stretched senior is the right tool: the total cost, the GDV, and the margin, so we can see which of the two sizing tests will bind and how much equity you would actually need to find. From there we compare a stretched senior facility against both a plain senior loan and a senior-plus-mezzanine stack, so the choice is made on the real cost and structure rather than on the headline leverage alone. Then we take the scheme to the lender camps that genuinely write stretched senior at the leverage and price that fit, and we manage the process through to drawdown. Because there is one lender and one charge, that process is usually quicker than arranging a two-lender stack.

Stretched senior buys you higher leverage and the simplicity of one facility, paid for with a higher blended cost of capital than plain senior.

If you want the background on the conservative end first, our note on senior development finance covers how the base senior loan is sized and priced, and our note on mezzanine finance covers the junior tranche route to higher leverage. Stretched senior sits between the two.

FAQ

Are you a lender?

No. We are a finance arranger and introducer. We bring schemes to the lender camps that fund stretched senior and manage the process, but the loan and the terms come from the lender, not from us. We are not FCA authorised, because this type of commercial development lending is unregulated.

How much more does stretched senior cost than plain senior?

Plain senior runs at about 9 to 12% per annum, and stretched senior is priced as a blended rate above that range, with an arrangement fee broadly in the 1 to 2% region. The exact figure depends on the scheme, the leverage point, and the lender. These are indicative bands, not a quote.

Will stretched senior always reach 75 to 80% of cost?

Not always. That figure is the ceiling on the loan to cost test. The loan is sized on the lower of loan to cost and loan to GDV, and the GDV cap of 60 to 65% can hold the loan below the cost-based ceiling on a tighter scheme. The end value has to support the debt.

When should I use senior plus mezzanine instead?

When you need to reach the top of the stack, around 85 to 90% of cost, which is above what stretched senior delivers. The trade-off is a second lender and an intercreditor agreement. If 75 to 80% is enough, stretched senior gets you there faster and more simply.
