Two bedrooms above a formula

The bedroom standard assigns a notional bedroom requirement using the ages, relationships and sex of household members. A couple is allocated one bedroom; another adult aged 21 or over is allocated their own. Children and younger people are paired under specified rules. The survey compares that requirement with the bedrooms available to the household.

One bedroom above the standard does not qualify as under-occupation here. Nor does the classification tell us that two rooms stand empty. Rooms converted to other uses are excluded unless respondents still describe them as bedrooms. That detail matters when the guest bed and the working desk share an address.

A very different picture for owners and renters

The national average conceals a large tenure gap. The annex records under-occupation in 54.7% of owner-occupying households, 15.0% of private-renting households and 9.5% of social-renting households. Each percentage describes households within that tenure, rather than its share of England’s under-occupied homes.

The distinction changes the design conversation. An owner deciding what to do with an extra bedroom and a renter fitting a desk beside the bed may both want a more useful home, but they begin with very different choices. A room makeover cannot supply the missing floor area.

A bedroom can have more than one use

A bed kept for a visiting parent has a purpose even on the nights nobody sleeps in it. So does a room used for sewing, quiet work or possessions that need somewhere accessible to live. These are possible uses, not findings from this table: the figures do not tell us what England’s spare rooms contain.

Before buying furniture for a spare room, write down what actually happens there over a month. A room that works daily as an office and occasionally as a bedroom needs a different arrangement from a guest room with a laptop balanced on the dressing table. The door still has to open when the bed is in use.

Keep overcrowding in view, and its dates separate

The same release estimates that 824,000 households were overcrowded, meaning they had fewer bedrooms than the standard required. Its annex gives 3.3%. That estimate combines three survey years, from 2022–23 to 2024–25, because the annual overcrowded sample is small. It should not be subtracted from the single-year under-occupation figure to produce a neat national space balance.

Start with the room’s obligations

For a room with several jobs, decide what must remain available and what can be moved without a major performance. A visitor needs somewhere for a bag; a working day needs space to pull the chair back. Keeping those small requirements visible is more useful than furnishing for a photograph and discovering later that the suitcase blocks the desk.

These statistics describe how bedroom provision is distributed. They cannot decide whether somebody should downsize or surrender a useful room. The practical question at home is more specific: whose needs must this space accommodate, and can they use it without clearing somebody else’s things first?

Methodology & sources

Source: MHCLG English Housing Survey 2024–25, Chapter 1: Housing quality and its Annex Tables 1.2 and 1.3, published 29 January 2026. The Room Study downloaded the official ODS and checked its displayed table values on 22 October 2026. Geography is England, not the United Kingdom.

Under-occupation uses the full 2024–25 household sample. Annex Table 1.3 reports 16,438 sampled households: 8,366 owner occupiers, 3,538 private renters and 4,534 social renters. Counts and percentages are weighted population estimates, not counts of surveyed people. The annex publishes household estimates in thousands; their precision should not be mistaken for an exact census count.

The chart and table retain the annex’s one-decimal percentage values. The lead rounds 39.8% to 40%, as the official narrative does. That narrative also rounds 54.7% to 55%, 9.5% to 10%, and 9.952 million households to 10.0 million. The apparent differences are rounding, not competing estimates.

The bedroom standard compares available bedrooms with a requirement based on household composition. Under-occupation means two or more bedrooms above that requirement; overcrowding means fewer bedrooms than required. Converted bedrooms are excluded unless respondents still identify them as bedrooms; unused habitable bedrooms are counted. The measure does not record empty-room frequency, room dimensions or satisfaction with the use of space.

Overcrowding uses the pooled 2022–23, 2023–24 and 2024–25 surveys, presented as a three-year average ending in 2024–25. Annex Table 1.2 reports a total sample of 43,489. It is shown as separate context and is not combined with the single-year under-occupation figures in the chart or used to calculate a residual category.

Room-planning observations are The Room Study’s editorial interpretation. The survey did not test furniture arrangements, measure spare-room use or demonstrate that any product improves household wellbeing.
