The scale of the need

The shortage has accumulated over decades

The housing requirement has two parts: homes for additional households and homes to relieve the shortage already experienced by people living here. Keeping pace with new demand leaves the existing shortfall untouched.

Comparative studies put that accumulated deficit in the millions. Centre for Cities estimated 4.3 million missing homes in its 2023 analysis of historic UK underbuilding against European comparators. The Centre for Policy Studies estimated a UK gap of 6.5 million in its 2025 homes-per-person comparison. These are separate studies with different methods and reference periods, rather than the lower and upper bounds of one official count.

The practical consequences include adults unable to establish independent households, overcrowding, insecure accommodation and households priced out of suitable homes. Existing housing need remains even when population growth slows.

Demand follows households as well as population

People share homes in different ways. Young adults forming households, separations and more people living alone change the number of homes required. Births, deaths, ageing and migration all affect the population and its household structure. A count of additional people cannot be read as an equal number of additional homes.

The ONS 2022-based migration-category projection shows England gaining approximately 2.4 million households between 2022 and 2032: an average of about 242,000 a year. One-person households are projected to grow particularly strongly. This is a demographic scenario based on stated assumptions, not a building target or a forecast that incorporates every housing constraint.

That changes the mix of homes needed. Family housing remains essential, alongside smaller homes, accessible homes and accommodation for older people. A national programme has to fit local household needs.

Immigration and emigration both enter the calculation

Immigration adds residents; emigration removes residents. Net migration is the difference. ONS provisional estimates for the year ending December 2025 show 813,000 long-term arrivals and 642,000 departures, giving net migration of 171,000 across the UK. This includes British nationals as well as people of other nationalities.

New building and net supply are different measures

England gained 208,600 net additional dwellings in 2024–25, down from 221,410 a year earlier. New-build homes accounted for 190,600. Changes of use and conversions also added homes, while demolitions reduced the total. The net-additions series measures the overall change in housing stock.

The last row is part of the 2024–25 total and must not be added to it. A year of completions is also different from construction starts or planning permissions: a consented or unfinished home cannot yet house a family.

The supply series records annual delivery; the household projection describes a longer-term scenario. Their different periods and assumptions prevent a precise annual deficit calculation. The policy requirement is sustained delivery that accommodates household growth and makes progress on existing need.

Homes must be within reach of work

A national total cannot establish that suitable homes are available where people need to live. A home elsewhere only meets a worker’s needs if employment, travel costs, journey times and family commitments make the move practical. Nurses, school staff and other on-site workers still need access to their workplaces.

ONS workplace-based affordability figures make the geography visible. In 2025, median house prices were 10.6 times median full-time earnings in London and 5.0 times in the North East; England’s ratio was 7.6. These compare homes with earnings where jobs are located. They show sharply different affordability pressures, rather than proving that every expensive area has the same shortage.

The delivery implication is specific: select sites against local housing need, nearby employment, actual rents and earnings, transport and service capacity. Assess homes in the surrounding commuting area as well as the council boundary. Empty homes and conversions can contribute where they are suitable, available and connected to work; their location and condition determine what they deliver.

The programme adds homes where they serve households

The proposal combines additional supply with an income-based affordability rule. Public land is useful when its location and infrastructure support a viable community. The pilot establishes delivery across ten sites; subsequent programmes need the same discipline in matching homes, households and work.

The measure of success is occupied, affordable homes in places where people can build a life. That requires more than counting units or naming a national target.
