Question to the Ministry of Housing, Communities and Local Government:

To ask His Majesty's Government what is their estimate of the number of uncontracted and unsold affordable homes across England; and how many housebuilders have been supported since the Section 106 Affordable Housing Clearance Service was launched in 2024.

The government does not collect or publish data on uncontracted and unsold affordable homes in England.

The Homes England clearance service launched in December 2024 to help improve the functioning of the market for affordable housing, by supporting buyers and sellers to find each other more effectively - with developers able to share details of unsold section 106 affordable homes for registered providers and local authorities to search.  Since its launch, as of March 2025, 411 organisations have registered. This includes:

• 113 housebuilders;

• 184 Registered Providers of social housing;

• 114 Local Planning Authorities.

The government calls on all developers with uncontracted Section 106 affordable homes, as well as registered providers and local planning authorities, to engage proactively with the service.
