Approximately one-third of newly built homes in London remained unsold to private buyers over the past year, according to recent data. Analysis by property adviser CBRE revealed that 34 percent of new residential units in the capital were withdrawn from the market after failing to find purchasers during the 12 months ending in March 2026. This figure marks a significant increase from the previous year, when 25 percent of new homes were unable to secure private buyers.

The rise in unsold properties highlights ongoing challenges in London's housing market, with developers reportedly pulling back on sales efforts amid fluctuating demand and broader economic uncertainties. While detailed reasons for the sales slowdown have not been fully elaborated, factors such as affordability pressures, changing buyer preferences, and market saturation have been suggested as contributing elements.

Industry observers note that the increase in unsold inventory may have implications for new housing supply and the pace of future development. Developers facing prolonged sales difficulties could reassess their project timelines or pricing strategies, potentially affecting the availability and cost of new homes in the capital.

The data underscores a complex landscape where the demand for new housing in London has not matched supply to the extent expected, raising questions about the balance between construction output and buyer capacity amid shifting market conditions.
