The mayors of three London boroughs have voiced their concerns regarding the recent policy changes made by Mayor Sadiq Khan, which they argue undermine the provision of affordable housing in the capital. Tower Hamlets, Hackney, and Lewisham have initiated a legal challenge against Khan, asserting that he failed to follow the proper statutory process and did not adequately consult with local councils before implementing the new policy.
In October 2025, the government and the mayor agreed to reduce the affordable housing quota for new developments in London from 35% to 20%, a decision made in response to stagnating house-building rates. While the government estimates that London requires 88,000 new homes annually to meet housing demands, only 31,000 net additional homes were constructed in the city during 2024-2025.
City Hall has defended the policy changes, stating that they aim to expedite planning decisions, encourage developers, and ultimately increase housing supply. However, the figures reveal that only 3,991 affordable homes were built in the same period, raising questions about the effectiveness of the new measures.
Concerns Over Housing Shortages
Mayor Zoe Garbett of Hackney described the housing situation in her borough as „desperate,“ highlighting that nearly 8,000 households are on the waiting list for council housing, with 3,500 families currently in temporary accommodation. She criticized the mayor’s approach, claiming that local authorities were not properly consulted and accusing Khan of prioritizing developers over community needs.
Garbett emphasized that Hackney’s planning rules require developers to offer at least 50% of new homes at affordable levels, contingent on a viability assessment. She clarified that the legal challenge is not intended to obstruct the mayor but rather to advocate for collaboration against developers who may not prioritize affordable housing.

Rising Costs and Housing Viability
The legal challenge comes amid record levels of individuals living in temporary accommodation, with London councils reportedly spending £5.5 million daily on homelessness. Analysis of government data indicates a nationwide decline in house building, with 99 out of 294 areas in England needing to significantly increase their housing output to meet annual targets.
Ian McDermott CBE, chief executive of the Peabody housing association and chairman of the G15, a coalition of London’s largest not-for-profit housing associations, noted that rising costs and challenging economic conditions are severely impacting the feasibility of affordable housing developments. He stated, „Rising costs and tough economic conditions mean many affordable housing developments are struggling to stack up financially and the system is under increasing strain.“
Local Perspectives on Housing Targets
Mayor Lutfur Rahman of Tower Hamlets expressed a preference for a borough-specific approach to affordable housing targets rather than a blanket 20% requirement across London. He argued that the affordable housing targets in Tower Hamlets remain viable, asserting that no developers have withdrawn from projects due to the borough’s requirements. Rahman urged councils to maintain their housing targets, emphasizing that developers value certainty and clarity in the planning process.
In contrast, Mayor Liam Shrivastava of Lewisham criticized the proposed changes as „political theatre,“ arguing that the issue is not merely a lack of housing supply, as evidenced by vacant developments in the borough. With 10,500 households on Lewisham’s housing waiting list and nearly 14,000 living in overcrowded conditions, Shrivastava insisted that the borough would not settle for reduced affordable housing targets.
Industry Reactions and Future Implications
Steve Turner from the Home Builders Federation, which represents private sector housebuilders in England and Wales, expressed support for the measures aimed at reducing affordable housing requirements. He noted that the current housing supply crisis in London is largely due to the unviability of many sites under existing requirements. Turner stated, „By insisting on a level that’s too high as a blanket, whether it be at a borough level or a citywide level, you’re going to prevent houses coming forward.“
Legal expert Nick Bano, a housing barrister at Garden Court Chambers in London, highlighted the councils‘ concerns regarding the extent of their consultation prior to the implementation of the new rules. He emphasized that local authorities, responsible for making planning decisions, are significantly affected by the policy and have a strong case for thorough consultation.
Political Context and Future Developments
The legal challenge has been formally submitted to the Greater London Authority (GLA), where Mayor Sadiq Khan serves as the executive responsible for key functions, including housing. Green Party leader Zack Polanski remarked that all Green councils in London are supporting this legal action to advocate for affordable housing, contrasting their approach with that of Labour mayors.
This challenge emerges in a politically charged environment, especially with Andy Burnham being mentioned as a potential successor to Prime Minister Keir Starmer, who recently announced his resignation. Burnham’s campaign has emphasized a significant increase in council house building, proposing to redirect the existing £39 billion affordable housing program towards social rent homes.
Previously, Khan acknowledged the housing crisis, stating, „Homes being built in London have dried up and it’s a nationwide problem. I’m not willing to stand by when that happens and so working with the government we’ve announced today a temporary short-term package of emergency measures to kickstart house building in London.“ City Hall has indicated that the urgency of the housing crisis necessitates immediate action to stimulate construction.
The government has attributed the housing supply challenges to a combination of escalating construction costs, high interest rates, the legacy of previous administrations, the impact of the COVID-19 pandemic, regulatory hurdles, and broader economic conditions.
