For millions of French families, the coming winter will bring more than just colder temperatures—it will bring higher energy bills. The Commission de régulation de l'énergie (CRE), France's energy regulatory authority, has announced that the reference gas sale price (PRVG) will increase by 5.8% on December 1, rising from €194.90 per megawatt-hour to €206.26. This adjustment, while seemingly modest in percentage terms, will translate to an average additional €16 per month for households with indexed gas contracts, affecting approximately 6 million families across the country.
"We are experiencing an international market price, we import 95% of our gas," explained Emmanuelle Wargon, president of the CRE, in a statement that underscores France's profound energy dependency. "This price increase reflects the fact that there has been less supply since the crisis in the Strait of Hormuz," Wargon noted, highlighting how international events directly impact French consumers.
The December increase represents just one chapter in a longer story of rising energy costs in France. For the average consumer, the annual 2026 gas bill is projected to rise by 11.8% compared to 2025, amounting to an additional €143 over the course of a year. This comes at a time when energy affordability has become an increasingly pressing concern. A 2026 barometer by the national energy mediator revealed that 34% of households reported difficulty paying their energy bills, a significant increase from 18% just four years earlier in 2020.
However, the 60% with indexed offers—roughly 6 million households—will see their bills climb.
Not all French households will feel the immediate impact of this price adjustment. The CRE estimates that about 40% of residential gas subscribers have fixed-price contracts that will shield them from this particular regulatory change. However, the 60% with indexed offers—roughly 6 million households—will see their bills climb. This divide creates a complex landscape where energy costs are not uniform, potentially exacerbating existing inequalities in how households experience economic pressures.
As French families brace for higher heating costs, the energy industry continues to report substantial profits. Five major oil and gas companies have announced cumulative net profits exceeding $50 billion, driven by hydrocarbon prices and refining activities. This contrast between corporate earnings and household financial strain adds another layer to the complex energy debate in France, raising questions about the distribution of benefits in the energy sector.
The price increase serves as a stark reminder of France's position as a net energy importer.
The December price adjustment is not an isolated event but part of a longer-term trend. As France moves through 2025 and into 2026, energy prices are expected to remain a significant factor in household budgets. The CRE's projections suggest that the average consumer will see their annual gas bill increase by €143 compared to the previous year, a substantial sum for many families already grappling with cost-of-living pressures.
In the face of these challenges, French households and policymakers alike are searching for sustainable solutions. The December price increase serves as both a warning and a motivation for France to accelerate its energy transition, balancing immediate needs with long-term resilience in an increasingly volatile global energy landscape.
