The United Kingdom’s core Retail Price Index (RPI) remained unchanged in May 2026, holding at an annual rate of 3.0%. The figure matches April 2026’s year-on-year reading of 3.0%, indicating that underlying retail price pressures, excluding volatile components, neither accelerated nor eased over the period.
The data, updated on 17 June 2026, compares price changes in May 2026 with those recorded in May 2025, following the same year-over-year methodology applied to April. The stable core RPI suggests that, on this measure, inflation dynamics in the UK retail sector have entered a period of relative steadiness, with no additional upward or downward momentum evident between April and May.
