  • Assessing the Impact of methodological improvements on the Consumer Prices Index

    Methodology | Released on 18 October 2016

    This paper sets out the impact of implementing two improvements in the Consumer Prices Index (CPI; the headline measure of inflation in the UK), CPI including owner-occupiers’ housing costs (CPIH), and their supplementary indices. These changes will not be applied to the Retail Prices Index (RPI). They are planned for March 2017. The first change is designed to improve the way that chain-linking is conducted, and is the result of an independent report on the double chain link; the second is the implementation of an additional level of detail (level 5, or ECOICOP) in the Classification Of Individual Consumption by Purpose (COICOP) structure. As the CPI is identical to the Harmonised Index of Consumer Prices (HICP), these improvements will also help us to better meet EU regulations.
