April Newsletter: The government has just announced a National Housing Bank and plans to build seven new towns
It's the kind of headline that sounds transformational. And in the long run, it might be.
But if you work in construction, architecture, or development, you already know the uncomfortable truth sitting beneath the announcement: the UK doesn't just have a housing ambition problem. It has a delivery infrastructure problem. And right now, those are very different things.
The numbers don't lie.
Private housebuilding starts are down 34% year-on-year, the fifth consecutive quarter of decline. Just 42,239 homes were approved in Q2 2025, a 19% drop on the year before. Planning delays are averaging over 18 months. The pipeline exists. But converting it to live sites is where the system is breaking down.
ICAEW's April 2026 analysis is worth reading carefully. It warns that without simultaneous action across planning reform, biodiversity net gain requirements, Section 106 obligations, and NIC pressure, the sector risks a self-reinforcing spiral: insolvencies reduce capacity, reduced capacity slows delivery, slow delivery pushes costs up, rising costs make schemes unviable, unviable schemes trigger more insolvencies.
The National Housing Bank and new towns programme are long-run structural tools. They don't fix what's happening on the ground this quarter.
What is happening on the ground this quarter:
The Future Homes Standard is confirmed. Part L goes live March 2027. On-site renewables are now mandatory. Timber is up 7.6% year-on-year. Cement and brick remain elevated due to energy costs. Tender price inflation is running at 3-4% for 2026.
Structural steel and imported timber are easing, which matters for frame packages, but M&E and envelope costs remain sticky. Every QS we know is reworking elemental cost plans right now.
From 30 September 2026, second staircases become mandatory in residential buildings over 18 metres under the Approved Document B amendments. If you're in RIBA Stage 2 or 3 on anything near that threshold, this isn't a future consideration, it's a present design constraint that changes your core layout.
The Building Safety Levy arrives in 2026 too. It's a new cost on new residential development, intended to fund unsafe cladding remediation on buildings outside developer agreements. It belongs in every viability appraisal being written right now.
Infrastructure is the outlier
HS2, Hinkley Point C, the Lower Thames Crossing - these remain the rare bright spots keeping parts of the contracting market busy. But they also illustrate the skills problem. The engineering and construction workforce is increasingly concentrated in major infrastructure. Residential capacity is thinning. That's not a short-term fix.
So what does the National Housing Bank actually change?
Potentially a great deal - over time. Access to patient, long-term capital is genuinely one of the structural barriers to building at scale, particularly for SME developers and housing associations who can't absorb the front-loaded costs of large-scale development. Seven new towns, if properly masterplanned with infrastructure delivered ahead of housing, could avoid the viability trap that's killed so many large-site allocations before.
But the word if is doing a lot of work in that sentence.
The history of UK housing policy is littered with bold announcements that met the planning system, the infrastructure funding gap, the skills shortage, or the interest rate cycle, and stalled. The question isn't whether the ambition is right. It is. The question is whether the machinery exists to execute it.
We are at an unusual moment. The policy intent is the strongest it's been in decades. The regulatory environment is tightening in the right directions - on safety, on energy performance, on accountability. The financing architecture is being rebuilt.
But the construction industry - its contractors, architects, quantity surveyors, developers, planners - is being asked to deliver more, to higher standards, with greater complexity, against a backdrop of margin compression, skills shortages, and input cost volatility.
That's not a reason for pessimism. It's a reason for precision. The firms and professionals who understand exactly what the regulatory and cost environment demands right now, and who build that into their advice, their designs, their appraisals, will be the ones still standing when the pipeline finally starts to flow.
