Columns, coverage and cadence

Columns

country_code (Eurostat geo code, for example DE, FR, EU27_2020), country (country name in English), consumer_type (household or business), dataset (the Eurostat dataset the row comes from), band_code, band and band_label (the consumption band and its range), tax_basis_code (I_TAX or X_VAT) and tax_basis (what the code means, in words), period (Eurostat half-year code, 2026-S1 means the first half of 2026) and period_label, price_eur_per_kwh / price_eur_per_gj (the price in euro), price_pps_per_kwh / price_pps_per_gj (the same price in PPS, purchasing power standards; blank where Eurostat publishes no PPS figure for that cell).

Coverage notes

The United Kingdom has no Eurostat figures after H1 2020 and Ukraine none after H1 2021, in both electricity and gas. Gas coverage is smaller than electricity coverage because several countries have no meaningful household gas market in the Eurostat collection: Finland reports no household gas prices at all, Poland’s household gas series ends at H2 2023, and Cyprus, Iceland, Malta, Montenegro, Norway and Kosovo do not appear in the gas datasets. Albania’s only household gas values in Eurostat are 0.0 EUR/GJ for 2021 and H1 2022; they are reproduced as published but should not be read as a real price.

Update cadence

Eurostat publishes these price collections twice a year: H1 figures (January to June) usually appear in the autumn of the same year and H2 figures the following spring. This package is refreshed after each Eurostat release, and the file names are updated with the new period at the same time. The electricity files were retrieved from Eurostat on 5 November 2026 and the gas files on 6 November 2026.
