The National Housing Bank goes live: £16bn and a new deal for SME developers
The National Housing Bank launches with £16bn to back SME house builders. What developers and brokers should know about the new funding landscape.

The strongest support environment for small and mid-sized builders in more than a decade. What the stack actually looks like on the ground.
The National Housing Bank launches fully in 2026 with £16 billion of capitalisation, alongside a new National Housing Delivery Fund, a £700 million extension of the Home Building Fund, and a fresh planning category for medium-sized sites. Taken together, it is the strongest support environment for SME house builders in more than a decade. What it means in practice, for a small builder trying to get out of the ground on a 20-unit site in the second half of 2026, is that the finance stack has more moving parts than ever, and stitching them together properly is the actual job.
What is on the table
Why this matters for the SME builder
The 10 to 49 homes bracket has been the squeezed middle of UK housebuilding for a decade. Too big for the pure self-build route. Too small for the plc pipeline. And increasingly under-served by high-street senior debt. This programme is aimed directly at that gap. Public capital fills the space that senior debt vacated between 2013 and 2020. Planning proportionality reduces both the cost and the cycle time of getting through committee. And the BNG simplification removes a real friction point on smaller schemes, where the requirement had started to eat viability rather than protect biodiversity.
Public money does not remove the need for private capital
This is the point that gets missed. Public facilities work best in combination, not isolation. Most SME schemes will still need senior debt and mezzanine or equity alongside a public facility, and the stack has to be structured around drawdown schedules, valuation gates and exit. Getting the structure right at term-sheet stage saves rework at legal, which saves weeks on programme, which saves cost. A public facility badly stitched into a private stack is worse than no public facility at all.
How Credco is placing these files
Four things make the difference on an SME development file:
If you have an SME development file you would like a second view on, development finance is one of the areas we place most, and we are happy to run through appetite and structure before you commit to a route. Get in touch.
“This is the most supportive backdrop for SME development we have seen in over ten years. The gap that closed most of the small builders in the mid-2010s, senior debt drying up between 5 and 50 units, is what all this is aimed at. Public capital does not sit on its own, though. It sits alongside private senior debt, mezz and equity, and the stack still has to work. For the SME developer sitting on a workable site right now, the real question is not whether the money exists. It is whether the deal is structured well enough to draw it down.”
