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

To ask the Secretary of State for Communities and Local Government, how many residential properties on brownfield land (a) in total and (b) as a proportion of all residential property sales were sold in each of the last five years.

The Department publishes data on residential property sales, based on Land Registry data. These are available in Live Tables 588 (annual) and 584 (quarterly) at: https://www.gov.uk/government/statistical-data-sets/live-tables-on-housing-market-and-house-prices

The Department does not, however, collect data on the proportion of these properties that were built on brownfield land.
