Our recommendations ahead of the Autumn Budget

As London’s largest group of housing associations, our members provide more than 850,000 homes across the country, including around 1 in 10 homes for Londoners. Delivering safe, high-quality housing for residents remains our top priority.

London is at the centre of a national housing crisis:   

• 1 in 50 Londoners are homeless

• 1 in 21 children are growing up in temporary accommodation.

  This is costing London boroughs £5.5 million every day, diverting vital resources away from long-term housing solutions.

Affordable housing is not just a social necessity – it is essential economic infrastructure:

• Each social home generates over £18,000 in annual social value

• Improving affordability drives broader economic productivity.

  Investment in affordable homes:

• Reduces pressure on temporary accommodation, welfare, and health services
• Supports people to work and contribute to the economy
• Leverages private finance, creating jobs, green growth, and stronger supply chains.

To ensure the housing system delivers for Londoners and supports the government’s ambition to build 1.5 million homes by the end of this Parliament, G15 is calling on HM Treasury to take action through three key measures:  

1. Provide Long-term Investment Certainty
   Introduce a 2026 rent settlement with a £3/week rent convergence mechanism, restoring financial capacity for social landlords, maintaining existing homes, and unlocking private finance for new social and affordable housing.
2. Tackle Supply and Planning Barriers
   Reform grant rules, strengthen planning capacity, and enable regeneration so providers can deliver the affordable homes London and the wider economy need.
3. Advance Fiscal Devolution for London
   Allow local reinvestment of housing and infrastructure revenues to support the long-term delivery of new affordable housing in the capital.
