London Affordable Home Starts Drop to 347 in Q2, Leaving 12,300-Home Gap

Delays from the Building Safety Regulator, high borrowing costs, unanswered funding demands have widened the shortfall just nine months before the March 2026 deadline

Overview

  • Only 347 affordable homes began construction in London during April–June 2025, the lowest quarterly total of the current programme.
  • Total starts stand at around 5,500, leaving London about 12,300–13,500 homes short of the revised 17,800–19,000 target with nine months remaining.
  • Enfield led boroughs with 181 starts, while 27 boroughs recorded fewer than ten, highlighting uneven delivery capacity across the capital.
  • City Hall blames funding gaps, rising building costs and regulatory delays at the Building Safety Regulator for the stalled start rate.
  • Industry groups point to Budget-driven uncertainty and weak first-time buyer demand exacerbating bottlenecks even as City Hall secures an £11.7 billion funding package and considers green-belt development.
