The United Kingdom’s annual inflation rate, measured by the Consumer Price Index (CPI), accelerated to 3.3% in March 2026, up from 3.0% in February 2026. The data, updated on 22 April 2026, indicate a reversal in the recent disinflation trend as price pressures picked up heading into spring.
On a year-over-year basis, the March reading shows that consumer prices rose more sharply compared with March a year earlier than they did in February versus its year-ago level. The comparison period framework means the current 3.3% figure reflects the change in prices between March 2026 and March 2025, while the previous 3.0% figure reflected the change between February 2026 and February 2025.
The uptick in CPI will likely draw attention from markets and policymakers who had been watching for a steady slowdown in inflation. The move from 3.0% to 3.3% suggests that inflationary pressures remain persistent, potentially complicating expectations about the timing and pace of any future monetary policy adjustments in the United Kingdom.
