Last month we advised users of a weighting error for diesel fuel within the ONS Producer Price Indices (PPI). While most tables were updated correctly, some indices in datasets 2 (MM22) and 8 (PPI reference table) were not but have now been updated today.
Subsequent quality assurance checks have identified a further issue with some detailed item prices feeding into incorrect groups within the food section of the PPI basket.
As a result, the ONS will not be publishing next week's PPI bulletin and data for November 2022 while further investigations are undertaken. While this is being completed we advise caution using the PPI datasets which may be subject to revision.
This issue only relates to PPI. Our Consumer Prices Inflation including owner occupiers' housing costs (CPIH) and Consumer Prices Inflation (CPI) release and datasets are completely unaffected by this error and will be published as normal at 7:00am on 14 December 2022.
We will keep users updated on our progress and will provide a further update in January. We apologise for any inconvenience caused.
In the meantime, if any users have any questions, please contact us at media.relations@ons.gov.uk.
