Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 17 March 2026 to Question 118908, what assessment underpins increases in rateable values of up to 295% for UK civil airports between 1 April 2021 and 1 April 2024; and what specific economic indicators were used to determine those increases.

All assessments are underpinned by statutory assumptions defined in Schedule 6 of the Local Government Finance Act 1988.

For the 2026 revaluation, we consider general economic circumstances and the receipts and expenditure relevant to individual airports at the valuation date 1 April 2024. As this is the first revaluation since Covid, a large number of ratepayers may see a significant increase in rateable value compared to the previous valuation date 1 April 2021, when the country was in a pandemic lockdown.
