What this measures

Interest paid on public sector debt in the financial year, in cash terms, on the PESA function basis.

What this doesn’t measure

The ONS monthly debt interest series, which is on a different accounting basis and includes the effect of RPI on index-linked gilts differently.

Important caveat

PESA classifies spending by function using the UN COFOG framework, so "health" is every public body's spending on health services, not the Department of Health's budget, and "defence" follows COFOG rather than the NATO definition. Figures are outturn for the whole public sector including local government and public corporations. Cash figures rise with inflation; the real-terms table restates them at 2024-25 prices with the GDP deflator. Classification changes are footnoted in the table: student loans from 2011-12, Network Rail from 2011-12 and the treatment of EU transactions after 2020. Total managed expenditure includes accounting adjustments that are not allocated to any function.
