London's Social Housing Waiting List Grows 30% in a Decade.
New data published this week by the London Assembly should stop us in our tracks.
As of December 2025, there are 341,421 households on the social housing waiting list across London. A decade ago, that figure was 263,493. That is a 30% increase, and it is four times higher than the 7% rise recorded across the rest of England over the same period.
This is not a natural disaster. This is the predictable, documented consequence of forty years of political choices.
The stock we destroyed
Let us start with the most uncomfortable truth. The total number of council homes in London has fallen from 715,000 in 1980 to 390,000 in 2024, a 45% decrease. Over that period, 316,000 council homes were sold in London through Right to Buy. That figure is startlingly close to the 330,000 households currently stuck on waiting lists in the capital.
We sold the homes. We did not replace them. And we are still living with the consequences.
Nationally, there are now over 131,000 fewer affordable homes than when Right to Buy was introduced in 1980. The Resolution Foundation has described the near-halving of affordable homes relative to population as "largely the result of failure to replace the social housing stock lost to Right to Buy sales." This is not a contested finding. It is settled evidence.
The borough-level reality
The London-wide figure masks extraordinary variation at borough level. Brent has seen a rise of just under 880% in the number of households on its social housing waiting list over the past decade, meaning the number is almost ten times the size it was.
That is not a statistic. That is a complete collapse of social housing supply in one of London's most densely populated, most deprived boroughs.
The human cost: one child in every classroom
When waiting lists grow and supply stays flat, families do not disappear. They end up in temporary accommodation.
The latest available data shows 74,720 households in temporary accommodation in London as of June 2025. London Councils estimates there is at least one homeless child in every London classroom.
Two-thirds of Londoners living in temporary accommodation are families with dependent children, many of whom are placed in poor-quality, overcrowded homes, often far from their schools and support networks. London Councils
We know what that does to a child's life chances. We have the evidence on educational attainment, on health outcomes, on long-term wellbeing. And we continue to allow it.
The financial collapse
This crisis is not only a human one. It is a fiscal one, and it is accelerating.
London boroughs are now spending £5.5 million a day on homelessness in 2024-25, up from £4.2 million a day the year before. The bulk of that, almost £5 million a day, goes on temporary accommodation alone. Net current expenditure on homelessness in London has risen by 42% in a single year.
Boroughs were forced to overspend their homelessness budgets by at least £330 million in 2024-25, representing a 60% increase on their original budget plans.
LSE research commissioned by London Councils found that eight London boroughs alone spent a combined £543 million on temporary accommodation in 2024-25, with all London boroughs facing an estimated £740 million funding shortfall, equivalent to £202 per household.
Critically, the amount national government reimburses councils for temporary accommodation spend has been frozen for 14 years. Councils have a legal duty to house homeless families. They cannot cap that spending. The system is designed to drain them.
The government is moving, but is it fast enough?
To be fair to the current government, it is not standing still. Right to Buy reforms announced last year will increase the qualifying tenancy period from 3 to 10 years and dramatically reduce purchase discounts. In 2024-25, local authorities reported 7,494 eligible Right to Buy sales, with only 3,593 replacement homes funded from those receipts. We are still losing more homes than we are building to replace them.
The £27.3bn Social and Affordable Homes Programme is the most significant investment in a generation, with a requirement that at least 60% of funded homes must be delivered at social rent. The King's Speech this month introduced a Social Housing Renewal Bill. These are genuine steps.
But the waiting list in London has grown by nearly 78,000 households in a decade. At the current trajectory, legislative ambition will take years to translate into homes families can actually live in.
What needs to happen
The evidence is unambiguous. We need social rent homes at genuine scale, in London and across England. We need a funding system for temporary accommodation that does not structurally bankrupt councils. And we need to stop treating a 30% rise in ten years as background noise.
Shelter's Director of Campaigns and Policy said this week: "The severe lack of social rent homes in London has left families languishing on waiting lists for years on end."
That is correct. And it will remain correct until we build the homes.
The data is in. The case is made. The question now is whether the political will matches the scale of the problem.
