Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 19 March 2025 to Question 37570 on Housing, whether the Valuation Office Agency collects data on the (a) total plot size of the curtilage of a dwelling and its surrounds including any garden and (b) the area size of the dwelling itself excluding any surrounds and garden.

The Valuation Office Agency only requires data on a dwelling’s total plot size when it is non-standard for a typical property of that type. Plot size is recorded in these instances because an unusually large or small plot could influence the property’s assessment for Council Tax.

The area size of the dwelling itself is recorded for all properties.
