As the ONS prepares to introduce the Household Cost indices – measures that show how the prices of items bought by each type of household change – onto a quarterly basis for the first time, we are temporarily suspending the publication of CPIH subgroups. However, we recognise that there is a current user need for these measures and, while the CPIH-consistent subgroup publication is suspended, we will publish provisional estimates for selected sub-groups. The expenditure weights will be updated to reflect changes in the overall CPIH and CPI weights; however, the updated expenditure totals will be allocated to subgroups in the same proportions as in 2022. The provisional estimates for January to March 2023 are available on the user-requested data pages of the ONS website. More information is provided in Section 8 of the Consumer Price Inflation, UK: May 2023 bulletin.
