To ask the Secretary of State for Housing, Communities and Local Government, what proportion of affordable housing units were built by (a) housing associations and (b) private developers in England in the last 12 months for which figures are available.

The Department collects data on affordable housing through funding sources and does not differentiate between housing associations and developers. A full breakdown of affordable housing provision by funding source is available in live table 1011c: https://www.gov.uk/government/statistical-data-sets/live-tables-on-affordable-housing-supply.
