London's Housebuilding Plummets by a Staggering 84% in Just One Decade, Leaving a Critical Shortfall!
It's a stark reality check for the UK capital: a recent study reveals that the number of new homes being built in London's private sector has crashed by a dramatic 84% since 2015. This alarming decline is happening even as London desperately needs an estimated 88,000 new homes every single year to keep pace with demand. Imagine needing to feed a growing family but your pantry is emptying at an unprecedented rate – that's the housing situation London is facing!
New research conducted by the consultants at Molior paints a grim picture. In 2015, construction work kicked off on a healthy 33,782 new private-sector residential homes. Fast forward to 2025, and that number has plummeted to a mere 5,547. That's a colossal drop, leaving many wondering what went wrong.
Lord Bailey, a prominent member of the London Assembly, has voiced his deep concern, stating that London's housing predicament has transformed from merely 'difficult' to outright 'devastating.' He emphasizes that ordinary Londoners are bearing the brunt of this crisis, facing immense pressure on their lives and livelihoods.
Even the Mayor of London's office acknowledges the severity of the situation. A spokesperson for the Mayor declared that tackling our urgent housing crisis is a top priority, assuring that the Mayor is diligently working to increase the supply of homes across all tenure types. But is it enough?
Lord Bailey elaborated on his concerns, telling the Local Democracy Reporting Service that this is no longer just a housing crisis; it has escalated into a crisis impacting stability, opportunity, and even human dignity. He sadly noted, "I warned years ago that the mayor's approach would lead to a collapse in housebuilding. Sadly, that is exactly what has happened." This is the part that truly sparks debate: was this collapse an inevitable outcome of policy, or a result of external factors?
Looking ahead, only about 18,326 homes are anticipated to be completed in London by the end of this year. This figure represents roughly half of the homes currently under construction. Even more concerning, an additional 14,053 homes are not expected to be finished until 2027 or even later. This means that for the government's ambitious two-year target of 176,000 homes for London, the current pace is falling short by a staggering 92%!
Adding to the crisis, construction work has ground to a halt on 5,009 homes across 51 development sites in the capital. Molior suggests this slowdown might be due to building contractors facing financial ruin from escalating construction costs or strategically pausing projects because of a sluggish sales market. But here's where it gets controversial: could developers be deliberately holding back to artificially inflate prices in the future?
The firm also highlighted that only 8,436 new homes were sold in London during 2025. This low sales volume is directly linked to the reduced number of new construction starts. To even approach meeting government targets, London would need to see at least 22,000 homes sold each quarter.
In an effort to inject momentum, a spokesperson for the Mayor of London mentioned that housing providers are being encouraged to bid for a substantial £11.7 billion in government investment through the Mayor's Affordable Homes Programme. This funding aims to boost the delivery of social and affordable housing throughout London. Furthermore, a new City Hall Developer Investment Fund, backed by an initial £322 million, is being launched to support large-scale development projects. The government is also backing plans to extend the Docklands Light Railway to Thamesmead, a move expected to unlock the potential for up to 30,000 new homes.
Mayor Khan has pointed to several factors contributing to the slowdown in housebuilding, including the "disastrous legacy of the previous government, high interest rates, the rising cost of construction materials, the impact of the pandemic and Brexit, and Building Safety Regulator delays."
Lord Bailey, however, remains critical, asserting, "It is time for the mayor to take responsibility. His policies have stifled development, slowed delivery, and left Londoners paying the price through rising rents, soaring house prices, and the painful reality of being priced out of the city they call home."
