Le plan de logement social flexible qui pourrait être le plan de Burnham pour la Grande-Bretagne

London Mayor Sadiq Khan today unveiled a groundbreaking flexible social housing strategy, marking a potential blueprint for future national housing policies under Prime Minister Andy Burnham. The initiative, outlined in the updated London Plan, a statutory development document guiding the city's growth over the next two decades, introduces localized affordable housing targets tailored to each borough rather than applying a uniform standard across the entire capital. Khan emphasized the importance of devolution, aligning with Burnham’s vision of decentralizing authority from Westminster. This shift reflects a broader political trend toward empowering local governments to address regional challenges more effectively. Burnham has consistently advocated for increased council housing, positioning it as a cornerstone of his economic and social reform agenda. In the latest iteration of the London Plan, Khan introduced varying affordable housing thresholds based on each borough’s specific conditions. Developers in areas with high property values and strong demand, such as Wandsworth, Lambeth, and Westminster, are now required to allocate 35 percent of new developments to affordable housing. In contrast, boroughs with lower property prices and financial constraints, including Ealing and Brent, face a lower threshold of 20 percent. These adjustments aim to balance the need for affordable housing with the practical realities of development in different neighborhoods. The proposal replaces a set of emergency measures previously implemented by Housing Secretary Steve Reed under the Labour government. These measures had reduced the required percentage of affordable housing from 35 to 20 percent, effectively offering developers a financial incentive to increase construction activity. However, despite these efforts, London continues to grapple with a severe housing shortage. Construction starts have plummeted by 84 percent over the past decade, with only around 6,325 private-sector homes beginning construction in the first quarter of 2026—an alarming shortfall against the city’s annual target of 88,000 units. Council-led housing has emerged as a critical alternative. Since 2018, nearly 30,000 new council homes have been completed or are in progress in London. Last year alone, 49 percent of all new council homes in England were built in the capital, underscoring its role as a leader in public housing initiatives. Khan and Deputy Mayor for Housing Tom Copley stressed that expanding council housing will remain a top priority, aiming to alleviate pressure on the private market while ensuring long-term affordability. The new flexible model is designed to streamline the approval process for developers by providing clearer guidelines based on borough-specific criteria. By eliminating protracted viability discussions over affordable housing percentages, the plan seeks to accelerate project timelines and improve overall efficiency. Copley noted that this localized approach allows for greater responsiveness to local needs, potentially increasing the rate of affordable housing delivery. The strategy also highlights the potential for devolution to yield tangible benefits. With mayors empowered to enact regionally appropriate policies, there is optimism that similar models could be replicated elsewhere in the UK. Copley suggested that the success of this approach could serve as a case study for other cities seeking to enhance their housing provision through localized governance structures. Looking ahead, the implementation of these changes will depend on continued collaboration between local authorities, developers, and regulatory bodies. As the city moves toward achieving the goal of 35 percent affordable housing in more boroughs by 2028, the effectiveness of this model will be closely monitored. For now, the announcement represents a significant step forward in addressing London’s complex housing landscape.
