Inflation in the UK
Consumer prices in the UK have risen 194.4% since January 1988, the start of the official series. That means £100 then buys what £294.42 buys in June 2026, so the same basket of goods now costs 2.9 times what it did. Over the most recent year on record, June 2025 to June 2026, prices rose 2.6%.

How inflation in the UK is measured
The figures above come from the UK Office for National Statistics (ONS series D7BT, dataset MM23). The series is indexed so that a chosen base year equals 100, and the calculator works out the ratio between any two dates you pick.
Coverage runs from January 1988 to June 2026, and updates automatically as each new release is published. Figures for the most recent periods can be revised by the statistics office after first publication.
