This dataset provides researchers with access to the detailed underlying data used in the production of consumer prices indices. The figures are provided for research purposes only, are not accredited official statistics, and users should exercise caution when drawing conclusions from their use. From March 2026, the existing price quote data will be updated to exclude individual price quote information for COICOP Divisions 1 and 2. This change reflects that we are no longer able to release individual price quotes where scanner data have been integrated with locally collected data. There will be no changes to the availability of data in the monthly consumption segment indices dataset. In addition, new regional consumption segment indices, weights, and counts of manually collected indicator marker codes (such as sales and recoveries) are being published. Additional outputs are also planned for release from summer 2026 and further details can be found in the Related links section of this page. These changes aim to provide data continuity whilst maintaining confidentiality across our microdata release.
Measures of monthly UK inflation data including CPIH, CPI and RPI. These tables complement the consumer price inflation time series dataset.
