The Standard That Invented a Crisis

1The number that runs the debate

There are 1.34 million households on the social housing waiting list.^[1] Labour ministers cite it as the primary justification for mandatory housebuilding targets — 1.5 million new homes over five years, with local authorities empowered to build council housing directly. The Green Party use it to demand that 150,000 homes a year must be built for social rent specifically. The Resolution Foundation’s Housing Outlook for Q2 2026 treats it as the self-evident measure of unmet housing need against which every policy must be calibrated.^[2]

2The 52% who need no crisis

Of the 1.34 million, 52% — approximately 696,000 households — are not recorded as having Reasonable Preference status.^[3] They are on the register because the financial incentive is large and the cost of registering is zero. Average social rents run at £129 a week nationally, against average private rents of £207 outside London and £393 in the capital.^[4] Registration is rational regardless of housing distress. This is not gaming the system. It is households responding sensibly to an incentive the system creates and makes no attempt to limit.

That leaves 645,000 who do hold priority status — known in the statutory framework as Reasonable Preference. Under the Housing Act 1996, Reasonable Preference covers five categories: homelessness or threat of homelessness; medical or welfare needs requiring a move; hardship; armed forces need; and — the largest single category — ‘insanitary, unsatisfactory or overcrowded conditions.’^[5] This last category accounts for 23% of all households on the national register: approximately 307,000 households.^[6] Holding it does not guarantee a social letting. It means only that the applicant has cleared the minimum bar for priority consideration. And it is here, in what that bar requires and how it is assessed, that the accounting fiction at the heart of the 1.34 million becomes visible.

3A standard built for one tenure, applied to another

The Decent Homes Standard was designed for social housing. It sets out what a council or housing association property must provide: freedom from certain defined hazards under the Housing Health and Safety Rating System, which range from the alarming (uncombusted fuel gas) to the prosaic (differences between floor levels); a reasonable state of repair; reasonably modern facilities; and efficient heating and insulation.^[7] When its logic is carried across into assessments of private rented conditions — whether directly through Decent Homes language or indirectly through HHSRS hazards, disrepair, overcrowding and energy-efficiency criteria — it risks turning ordinary defects in England’s old private rented stock into evidence of social housing need.

Private rented stock is not social housing. It was not built to the same specification, is not maintained under the same regulatory framework, and is not owned by landlords with the same incentive structures. The principal-agent problem in private renting is structural: landlords bear maintenance costs while tenants receive the benefit of a well-maintained property, producing systematic under-maintenance at the margin relative to owner-occupied stock. This is not a problem, per se — it is the predictable consequence of a tenure type in which ownership and occupation are separated. However, applying a standard calibrated to a subsidised, regulated, professionally managed social home to stock operating under entirely different conditions will always produce findings of inadequacy. Those findings do not reflect a housing crisis; it is simply a way to articulate the difference between two non-comparable types of housing.

The consequences of this category error — the comparing of apples with oranges — flow directly into the waiting list. A family renting a period property with single-glazed windows, an ageing boiler, and intermittent damp may qualify for Reasonable Preference under the insanitary or unsatisfactory conditions category, depending on the local authority’s allocation policy and assessment. So does someone in a Victorian terrace with inadequate loft insulation. So does anyone in a pre-1970 property whose heating system falls below the EPC threshold implied by the standard. These are not unusual conditions — they are the normal condition of a very large proportion of England’s housing stock, stock that is old because England’s housing stock is predominantly old, and that carries the characteristics of age, because age has characteristics.

4The King qualifies

To illustrate how wide these criteria are in practice: an assessor applying the Decent Homes Standard would find category 1 hazards in Buckingham Palace. On energy efficiency alone — a Grade I listed building, largely uninsulated, heated by ageing systems — it fails the standard’s fourth criterion. The National Audit Office flagged a maintenance backlog in the building running to £369 million in 2016; that is precisely the state of disrepair the standard’s second criterion is designed to catch.^[8] Excess cold hazards in winter would be triggered across large portions of the building. The point is not that the King is about to join the housing register. It is that modern adequacy tests can classify old, inefficient and expensive-to-maintain property as deficient without proving acute housing need. Approximately one in ten of those currently on the register qualify on grounds no more specific than those that would apply to him.

The state sets a standard that generates inflated need, publishes the inflated figure, and the sector uses the figure to demand more of the product. A perfect circle.

5The circle nobody breaks

This is not a coincidence or an administrative anomaly, but the direct consequence of using a standard designed for one context to assess the adequacy of provision in another. The Resolution Foundation’s report commits the same error in a different manner. It benchmarks private rented conditions against social housing and concludes that the private rented sector is failing the households within it. In this a perfect circle is described: the government sets a standard that generates inflated need, publishes the inflated figure, and the sector uses the figure to demand more of the product whose inadequate supply the standard was designed to measure.

The Resolution Foundation does not acknowledge any of this. It does not ask whether applying social housing standards to private stock might inflate the apparent need figure its policy recommendations are calibrated against. It does not engage with the mechanism by which the Decent Homes Standard, applied to England’s predominantly old private stock, accounts for 23% of all households on the national register. These are not difficult questions, and they are questions the report had the data to ask. It does not, because asking them would require confronting the possibility that the crisis is smaller than the number advertises, and the remedy rather less obvious than the politics it attracts. A larger apparent need justifies larger programmes, larger budgets, larger ambitions. The sector that benefits from those programmes does not scrutinise the methodology that generates them. Neither does the research foundation that publishes the analysis. Neither, apparently, does the government that set the standard in the first place.

6An honest accounting

But what would an honest accounting look like? It would begin by separating the three components of the 1.34 million: the 696,000 not recorded as having Reasonable Preference status, responding rationally to a financial incentive the system creates; the 307,000 qualifying on insanitary or overcrowded grounds, many of whom are living in conditions that are normal for their tenure type rather than evidence of crisis; and the residual 338,000 with priority status on grounds of homelessness, medical need, or genuine hardship.

Note: components as recorded in MHCLG local authority housing statistics and social housing lettings releases for 2024/25. Figures rounded; shares of the 1.34 million total.

Against that residual, the only externally verified acute need figure in the system — the 131,140 households in temporary accommodation at 31 March 2025, formally homeless and placed by their council at public expense^[9] — suggests that the floor of genuine acute need is somewhere between 130,000 and 338,000. Not 1.34 million.

Before any government commits hundreds of billions to a programme built on that figure, it should ask what the figure actually represents. The answer is available in its own published data. It has simply never been incentivised enough to look.

7Nobody intended this. Nobody will look

The Decent Homes Standard was designed to protect social housing tenants. Nobody intended it to manufacture a housing crisis in the private rented sector. Nobody modelled what would happen to the apparent need figure if it did. But the figure now underpins billions in committed expenditure, an entire sector’s case for expansion, and the policy programme of at least two political parties. Nobody has found it in their interest to look too closely at what it counts.
