London's Housing Crisis: 84% Drop in Housebuilding Since 2015 (2026)

London's Housing Crisis: A Decade of Decline and Disappointment

The housing market in London is facing a dire situation, with a staggering 84% drop in private-sector housebuilding since 2015. This shocking revelation comes from a recent study, leaving many to wonder what went wrong and where to go from here. But here's the catch: London needs 88,000 new homes every year to meet its housing demands!

The study, conducted by Molior, reveals that the number of new private residential homes starting construction has plummeted from 33,782 in 2015 to a mere 5,547 in 2025. This drastic decline has not gone unnoticed by those in power.

Lord Bailey, a London Assembly member, paints a grim picture, stating that the housing crisis has taken a turn for the worse, affecting ordinary Londoners the most. But is this crisis solely the result of recent policies and decisions? The Mayor of London's office seems to think otherwise.

A spokesperson for the Mayor, Sadiq, defends the current administration's efforts, claiming that tackling the housing crisis is a top priority. They assert that the Mayor is doing everything in his power to increase housing availability across all tenures. But is this enough to make up for the massive shortfall?

Bailey's response is a stark contrast, suggesting that the crisis goes beyond housing. He argues that it's a crisis of stability, opportunity, and dignity, and that the Mayor's approach has directly led to the collapse in housebuilding. But is this a fair assessment, or is there more to the story?

The numbers tell a concerning tale. By the end of this year, only 18,326 homes are expected to be completed, which is just half of the homes currently under construction. And the future doesn't look much brighter. A staggering 14,053 homes won't be ready until 2027 or later, a mere 8% of the government's ambitious two-year target of 176,000 new homes for London.

Adding to the woes, construction has been halted on over 5,000 homes across 51 sites in the city. Molior attributes this to contractors facing financial difficulties due to high construction costs or intentionally pausing work due to weak sales. The firm highlights the direct impact of low sales on construction starts, with only 8,436 new homes sold in 2025.

To meet the government's targets, a whopping 22,000 homes would need to be sold each quarter. But is this target realistic, given the current market conditions?

The Mayor's office remains optimistic, announcing a record £11.7 billion investment opportunity for housing providers through the Mayor's Affordable Homes Programme. They also plan to launch a City Hall Developer Investment Fund with an initial £322 million to support large-scale projects. Additionally, the government's support for extending the Docklands Light Railway to Thamesmead is expected to facilitate the development of 30,000 new homes.

However, Lord Bailey places the blame squarely on the Mayor's policies, claiming they have stifled development and left Londoners struggling with rising rents and house prices. But is this a fair criticism, or are there other factors at play?

The debate continues, leaving many to wonder what the future holds for London's housing market. Will the city overcome this crisis, or will it continue to struggle? What do you think? Is there a solution in sight, or is this a complex issue with no easy answers?
