London's housing crisis deepens as construction starts collapse by 80% in a decade

London's housing market is nearing a standstill, with construction starts plummeting by over 80% in the last decade. By early 2027, only 15,000 to 20,000 new homes will be underway—far below the 60,000 to 65,000 annual average seen between 2015 and 2020. Business leaders are now urging action to revive the struggling sector amid wider economic challenges in the capital.

The sharp decline in housebuilding reflects a mix of regulatory hurdles and rising costs. Stricter safety rules introduced after the Grenfell Tower disaster have created a backlog in planning applications, delaying projects at multiple stages. At the same time, soaring construction and financing expenses are pushing developers to abandon or scale back schemes.

London's economic struggles are deepening the crisis. The city's unemployment rate hit 7.6% in late 2025—the highest in the UK and still climbing. This downturn has weakened demand and made funding even harder to secure. To tackle the slowdown, industry groups are proposing several measures. They suggest extending and expanding temporary pro-housebuilding policies introduced last October. A pause on the *Building Safety Levy* is also recommended to ease financial pressure on developers. Additional proposals include new permitting rights for temporary housing and fast-tracking certain projects as *nationally significant infrastructure* to speed up approvals.

Without intervention, London's housing pipeline will remain severely restricted. The drop in construction aligns with broader economic difficulties, including record unemployment and financial strain on developers. If adopted, the proposed measures could help clear delays and revive building activity in the coming years.
