London is facing one of the most severe housing shortages in Europe. According to research cited in the article, the city would need about 1.1 million additional homes to reach the average number of homes per person seen across Western Europe. Yet housing construction has slowed dramatically, with only 4,170 new housing starts in 2024-25, far below the city’s annual target of 88,000 homes. During the same period, London’s population increased by roughly 100,000 people, further widening the gap between housing supply and demand.
The article argues that one of the main obstacles is London’s planning system, much of which dates back to the 1940s. Unlike zoning systems used in many countries, development proposals are reviewed individually by local authorities, often resulting in lengthy approval processes, extensive documentation requirements, and subjective decisions. Some projects spend years in review before being rejected or delayed.
Additional challenges include high construction costs, elevated interest rates, labor shortages, and stricter safety regulations introduced after the Grenfell Tower fire. Developers say these rules, while intended to improve safety, have significantly increased costs and slowed approvals.
The consequences are widespread. First-time homebuyers face prices that are about 10 times average incomes, while renters spend roughly 42% of their income on housing. The shortage is also affecting economic growth, labor mobility, and the ability of younger residents to remain in the city.
British national and London authorities are pursuing planning reforms to accelerate construction, simplify approvals, and increase housing supply. However, political opposition, local resistance, environmental restrictions, and bureaucratic complexity continue to make large-scale reform difficult.
