What is the short version?

  • One of the biggest items of spending, after social protection, health and education.
  • It moves with inflation and interest rates: index-linked gilts pay more when prices rise, and the Bank of England’s quantitative easing passes on changes in its interest rate.
  • Not all of it is interest on borrowing: HM Treasury counts the notional interest on public service pensions in the same heading, shown here as its own line.

Where it is projected to go

Net interest as a share of GDP, OBR projection (july-2026)

A projection under the OBR’s assumptions, not a forecast of what governments will do. Net interest is interest paid less interest received, so it is lower than the gross figures above.

Cash is as published. Real terms are in 2025-26 prices, using HM Treasury’s GDP deflator. Per resident divides by ONS mid-year population for the area the body serves. Changes compare the same body in consecutive years.

What these figures do and don't show

  • Gross, not net. The main figures are interest paid; the OBR projection is net of interest received.
  • Pension interest is included. HM Treasury’s debt interest heading includes the notional interest on unfunded public service pensions; it is shown separately in the drill-down.
  • The long run joins sources. Before 1988-89 the series is the OBR’s historical database, on a cash basis before 1998-99.
  • Not split by nation, because the debt is the UK’s.
