Letter from the Secretary of State to the Chair dated 25 March 2026 concerning Homes for London

From: Housing, Communities and Local Government Committee

Summary

Secretary of State Steve Reed updates the Housing Committee Chair on the Government's Homes for London package, a time-limited support initiative for housebuilding. The package comprises five elements: a new planning route requiring 20% social/affordable housing with no viability assessment; temporary CIL relief; removal of density-constraining London Plan guidance; expanded mayoral planning call-in powers; and £324 million for a City Hall Developer Investment Fund targeting stalled sites.

Key findings

  • New planning route allows developers to skip viability assessments if committing to at least 20% social and affordable housing, open until 31 March 2028
  • Temporary CIL relief for eligible schemes applying before 31 March 2030, with higher relief for schemes exceeding 20% affordable housing
  • Removal of dual aspect and cycle storage density constraints from London Plan Guidance as a signal of travel pending new plan adoption
  • Mayoral planning call-in powers expanded via secondary legislation effective May 2026 to accelerate housing delivery
  • £324 million initial allocation to City Hall Developer Investment Fund to prioritise housing completions on stalled sites
