England is hurtling towards one of the most severe supply-demand imbalances in its modern housing history, with the number of households forecast to swell by 17% to 27.6 million by 2040, a demographic shift that threatens to redraw the investment landscape across every region and tenure.
Fresh analysis from multi-disciplinary development consultancy Marrons paints a stark picture for developers, landlords and institutional investors alike. Already more than 1.3 million households are languishing on local authority housing registers in 2025, and a further 320,600 social homes are projected to disappear from the national stock by 2040 if present trends persist, a hollowing out of the affordable sector that will ripple through the private rental and ownership markets.
For property investors watching regional hotspots, the figures make compelling reading. The South West is pencilled in for the sharpest rise in household formation at 20%, followed by the East Midlands, East of England, Greater London and the South East, each forecast to grow by 18%. The North East brings up the rear at 14%, though even this slower pace will test a planning system widely acknowledged to be creaking.
The generational split is equally telling. First-time buyer households aged 25 to 44, the beating heart of the mortgage market, are expected to expand by 14% to 16.1 million. Student-age and young professional households between 19 and 24 will climb 9% to 710,800, while the later-living cohort aged 65 and over is set to balloon by 36% to 9.4 million. That last figure alone underscores the investment case for purpose-built retirement living, a sector that has struggled to scale in Britain despite mounting demand.
Dan Usher, economics director at Marrons and a specialist in housing need evidence, warned that the country is drifting into “a structural mismatch between the homes England needs and the homes being delivered”.
“Household growth is accelerating across all age groups, but supply, particularly in social and affordable housing, is not keeping pace,” he said. “The scale of projected losses to social housing, combined with record waiting lists, points to a system under sustained strain. Without intervention, affordability pressures will intensify and access to homeownership will become increasingly out of reach for many.”
Mr Usher added that the Government’s proposed revisions to the National Planning Policy Framework, in particular policy HO7, would place greater emphasis on delivering homes that reflect evidenced local need, raising the stakes for developers seeking to unlock sites. “This makes robust, up-to-date data more important than ever in supporting planning applications and unlocking sites,” he said.
“The challenge isn’t just how many homes are built but whether they reflect the way people actually live, and will live, in the years ahead. Without a step change in delivery, we risk locking in a housing crisis that will become far more difficult and costly to resolve.”
Originally published in May 2024, the Marrons research has been refreshed with the latest datasets for its Housing 2040: Phase II report. The new edition draws on the Office for National Statistics’ 2022-based household projections, released in October 2025 and the first such figures in more than five years, covering both overall 16+ household growth and a detailed age demographic breakdown.
The analysis is supplemented by local authority housing register data for 2025, offering a near real-time snapshot of unmet social housing need, alongside movements in social housing stock between 2014/15 and 2023/24, including demolitions, Right to Buy sales and new completions.
For investors, registered providers and local authorities, the findings amount to a region-by-region playbook for aligning pipelines with the shape of future demand — and a warning that capital deployed without reference to these shifting demographics risks missing the mark in the decade ahead.
