Inflation calculations use the ONS Composite Price Index (1751–1948) spliced with the Retail Prices Index (1949–2025) — the canonical long-run UK price series, matching the methodology used by the Bank of England's own Inflation Calculator. The current series is referenced to 2015 = 100. The latest CPI release covers March 2026 (released by the ONS on 22 April 2026): headline CPI was 3.3% (up from 3.0% in February), CPIH 3.4%, and Core CPI 3.1%.
The Bank of England's Monetary Policy Committee targets annual CPI inflation at 2% as a symmetric point target set by HM Treasury. Bank Rate was held at 3.75% on 30 April 2026 (vote 8–1; the third consecutive hold). The MPC's April 2026 Monetary Policy Report sets out scenarios in which CPI could rise above target later in 2026 due to the conflict in the Middle East affecting energy prices, with one extreme scenario showing CPI peaking around 6.2% in early 2027. Past inflation rates are not a guide to future inflation. Rates and figures are subject to change.
