Starting from January 2026, the consumer price indices will be calculated on the base of updated Classification of Individual Consumption by Purpose (CZ-COICOP) see CZ-COICOP_2018 

Starting from January 2026, according to Regulation (EU) 2016/792 of the European parliament and the Council also new index time series with the base period average of 2025 = 100 will be introduced. The indices to other bases will be calculated from this time series (previous month = 100, corresponding period of last year = 100 and annual rolling average, i.e. the average of index numbers over the last 12 months to the average for the previous 12 months).
