The data found in versions of this dataset released between November 2020 and February 2025 are incorrect. This is because of an error identified with the chain-linking methods used to calculate Producer Price Indices (PPI) and Services Producer Price Indices (SPPI) since November 2020 when chain-linking methodology was introduced.
On 21 March 2025, we announced a pause to the PPI and SPPI, because of this error.
We also requested that the Office for Statistics Regulation (OSR) accreditation of the PPI statistics be temporarily removed from all releases dating back to November 2020, when this annual chain-linking was first introduced.
We restarted the publication of PPI and SPPI on 22 October 2025 following a period of reviewing, correcting and quality assuring the index weights and chain-linking methodology. This is described fully in our Impact of correction to chain-linking methodology article, which was published on the same day.
This MM22 dataset previously published alongside the statistical bulletin has now been discontinued and will no longer be updated. The indices published in the MM22 are available in the PPI time series dataset.
We apologise for these corrections.
