Question to the Department for Levelling Up, Housing & Communities:

To ask the Secretary of State for Housing, Communities and Local Government, what estimate he has made of the proportion of planning permissions granted that were for affordable housing units in England in the last 12 months for which figures are available.

The Department publishes an estimate of the total number of housing units granted planning permission in the quarterly planning application statistics statistical release: https://www.gov.uk/government/statistics/planning-applications-in-england-july-to-september-2019

The statistics do not split permissions between affordable and market housing

Section I10 of the Local Authority Housing Statistics includes figures for the numbers of affordable units granted final planning permission during the year as part of developer (section 106) contributions. This will be a subset of all affordable planning permission.
