New data from NHBC, the UK's biggest provider of warranties and insurance for new homes, shows the housing supply pipeline weakening further, with 26,231 new homes registered in Q3 2026 — a 13% drop from 30,279 in Q3 2025. The figures come as the Autumn Budget approaches, highlighting pressure on policymakers to shore up demand and ease delivery constraints.

Affordability challenges and supply-side hurdles weighed on activity. Private sector registrations declined 8% to 18,359 from 20,054 a year earlier, while the rental and affordable segment fell 23% to 7,872 from 10,225.

Daniel Pearce, Chief Strategy Officer at NHBC explains: "The housing industry is at a critical point. Demand remains fragile, affordability is stretched and our latest figures show that the pipeline of new homes is continuing to shrink. Without action to support demand and tackle the barriers to delivery, increasing housing supply will remain extremely challenging.

"The Government's proposed Your First Home equity loan scheme is a significant and welcome step towards tackling one of the market's biggest challenges - affordability. The Budget now needs to provide clarity on how this scheme will operate. Targeted support for first-time buyers could help more people achieve home ownership while supporting demand for new homes, but its effectiveness will depend on getting the design right, including the nature of developer contribution and ensuring that any price and salary caps are set to reflect local market conditions and support viability and affordability.

"Alongside planning reform, greater regulatory certainty and stability is critical to investor and house builder confidence and to long-term delivery. A clear forward programme of regulatory change, with sufficient lead times and coordinated implementation, would give businesses greater confidence to invest in delivering more new homes, including in the skills and capacity needed to support it."

Ten of the UK's 12 regions recorded year-on-year falls in Q3 2026, led by the South East (-32%), Northern Ireland (-32%) and Wales (-24%). Yorkshire and The Humber posted the strongest growth (+27%), with the West Midlands also rising (+10%).

In London, registrations settled back to roughly Q3 2025 levels after a 170% year-on-year spike in Q2 2026. While quarterly numbers in the capital can swing with the timing of major schemes, the longer-term picture remains muted: registrations have dropped from 5,130 in Q3 2019 to 1,223 in Q3 2026.

All house types saw declines year-on-year in Q3 2026. Only 267 bungalows and 3,217 apartments were registered, as builders focused on viability and areas of relatively stronger buyer demand.

Looking ahead to the Autumn Budget, Daniel Pearce, Chief Strategy Officer at NHBC adds: "Our new homes data underlines the scale of the challenge facing Government and the industry if it is to materially increase housing supply. The proposed Your First Home scheme is a welcome and important step, but there is no single solution. Sustainable growth will require action on both demand and supply - improving affordability for buyers while creating conditions for developers and investors to build with confidence by considering delivery costs, planning and regulatory constraints and investment barriers. The Budget is an important opportunity to make progress on both sides of the equation."
