French regulated natural gas reference sale price increase December 2026, Digi Mart USA News (France): There has been no regulated gas sale tariff in France since July 1, 2023. To help consumers compare supply offers, the Energy Regulatory Commission (CRE) publishes a monthly gas reference sale price (PRVG), which serves as a guide when choosing a new offer.
It is not a commercial offer that consumers can subscribe to, although some market offers are indexed to it.
The gas reference sale price is made up of three components. Only the supply component changes on December 1, 2026.
Following higher prices on gas markets in October compared with September, the PRVG will rise by an average of 5.8% including tax on December 1, to 206.26 euros per MWh including tax, up from 194.90 euros per MWh including tax on November 1.
The CRE estimates the impact on bills at an average of 16 euros including tax in December for consumers whose offers are indexed to the PRVG. Households with fixed-price offers, which represented about 40% of residential gas consumers at the end of 2025, are not affected, as these offers provide stability during periods of rising prices.
The annual 2026 bill for an average consumer will rise 11.8% compared with the 2025 annual bill, an increase of 143 euros including tax. As of June 30, 2026, 10.23 million households held a natural gas contract.
