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).

We have corrected an error in the "Price Setting TS (WTD)" tab and the unweighted Price Setting table in the "Business Operations" tab. The previous version did not include 640 respondents who answered "Not sure" to the corresponding question. This was caused by a technical error in our analytical pipeline which caused these responses to be replaced by blank values. This has now been resolved. No other data was affected by this issue.
