Provides files to download data as it existed for this dataset on previous dates.

Statistics are most often revised for 1 of 2 reasons:

  1. For certain statistics initial estimates are released with the expectation that these may be revised and updated as further data becomes available.
  2. Revisions may also be made when methods or systems are changed.

These types of planned revisions should not be confused with errors in released statistics, which are genuine mistakes. Such mistakes occur rarely and, when they do happen, corrections are made in a timely manner, announced and clearly explained to users in line with the Code of Practice for Official Statistics (Principle 2, Practice 7).

The price quote files (for the period March 2017 to November 2018) contained within our release was found to have previously excluded potato items (212309-212311). This has now been rectified and ONS apologises for any inconvenience this may have caused. For further information please contact cpi@ons.gov.uk.

Important notes and usage information

Data are broadly at the geographic level of Nomenclature of Territorial Units for Statistics (NUTS) 1 (for example, South East England, West Midlands, Wales). This level of detail was chosen to ensure that no individual retailer or service provider will be able to be identified and therefore is in line with the assurances given to data providers. For the same reason, a very small number of item indices (six) are also unavailable. With effect from the January 2017 CPI publication, these data will be published on a monthly basis showing the latest month data.
