Gas sales benchmark price to rise 6.6% in November

The gas sales benchmark price is composed of three parts:

• the supply, which includes the supply costs and costs associated with that natural gas supply activity;
• routing, i.e. network and storage tariffs;
• taxes (TVA, excise duty on natural gas and transmission tariff contribution - CTA), decided by the State.

At 1^er november 2026, only the « supply » share is changing. The Energy Regulatory Commission (CRE) states that the benchmark price for gas sales will be €194.90 TTC per megawatt hour (MWh), against €182.88 TTC/MWh in october, an average increase of 6.6% TTC month on month. This increase is linked to the increase in gas prices observed on the markets during the month of September.

This will have the consequence an average TTC €12 increase on invoices. This increase concerns consumers whose offers are indexed to the gas sales benchmark price. Households that have subscribed to a fixed-price offer are therefore not affected by this development.

The Energy Regulatory Commission considers that the 2026 annual bill could be on average 11% higher than the 2025 annual bill (i.e. an increase of around €135 TTC), if the situation remains roughly stable by the end of the year.

What is the benchmark price?

The benchmark price for natural gas sales published monthly by the CRE informs consumers in the context of the end of the regulated gas sales tariff (RGST).

It is published for information purposes and represents an average estimate of the costs incurred by suppliers in supplying natural gas to a residential customer.

For consumers, it serves as a compass for comparing offers, giving them an idea of the price at which regulated tariffs would have been maintained. The CRE specifies that suppliers now freely build their offers according to the supply conditions (energy costs on the wholesale market), their commercial choices and the contractual conditions they offer. However, some of the marketed offers are indexed to the gas sales benchmark price.
