Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, if he will estimate the number of people in the UK who own property worth over £1 million.

The information requested is not available.

Information on the number of property transactions over £1m is available at the following address: https://www.gov.uk/government/collections/property-transactions-in-the-uk

However, recently transacted properties form only a small proportion of the total stock of properties. Many property transactions will also involve multiple purchasers. Finally, many historic purchases below £1m will now be worth more that £1m due to property price inflation. Therefore this information should be considered very much a lower boundary.
