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).

Important notes and usage information

  • Indices for the latest 2 months are provisional due to the level of imputation present for items where the latest prices are not available. The latest 5 months are subject to revisions in light of (a) late and revised contributor data and (b) revisions to seasonal adjustment factors which are re-estimated every month.

  • All of the data included in this dataset is published on a 2010=100 basis.
