(1) Regulation (EU) 2016/792 lays down a common framework for the development, production and dissemination of the following harmonised indices: the harmonised index of consumer prices (HICP), the harmonised index of consumer prices at constant tax rates (HICP-CT), the owner-occupied housing (OOH) price index and the house price index (HPI). 

(2) Article 5(5) of Regulation (EU) 2016/792 establishes 2015 as the common index reference period for the harmonised indices. Article 5(6) of that Regulation specifies that the harmonised indices and their subindices are to be rescaled to a new common index reference period every 10 years after the latest rescaling, starting from 2015. It is therefore necessary to define the detailed rules for that rescaling. 

(3) The rescaling of the already transmitted data to the Commission (Eurostat) requires the division of the full time series of harmonised indices and their subindices corresponding to the previous common index reference period by a rescaling factor. Member States should calculate the rescaling factors and transmit them to the Commission (Eurostat) which should rescale the existing time series. 

(4) Commission Delegated Regulation (EU) 2024/3159 introduced changes in the compilation of the HICP and HICP-CT regarding the classification of consumption and the inclusion of games of chance that apply to the transmission of these indices to the Commission (Eurostat) from the reference month of January 2026. For reasons of cost-effectiveness and to ensure that these changes do not impose a significant additional burden on Member States, it would be appropriate that this Regulation is applied simultaneously with the changes introduced by Delegated Regulation (EU) 2024/3159. 

(5) The measures set out in this Regulation are in accordance with the opinion of the European Statistical System Committee,
