By What Gas Costs in France: The Prix Repère Gaz
Since 1 July 2023, there is no regulated gas tariff in France. All consumers are on market-rate contracts. To give everyone a clear benchmark, the energy regulator (CRE) publishes a monthly reference called the Prix Repère de vente de Gaz (PRG).
The PRG is not a tariff you can subscribe to — it is the CRE's calculation of what gas actually costs to supply at market rate. Think of it as the "fair market price" for gas in France. Suppliers then offer their own rates, usually as a percentage discount off the PRG.
The PRG has risen sharply in 2026: the heating-profile reference went from about €0.10/kWh in February to €0.135/kWh in September 2026, driven by higher wholesale prices. GRDF's network charges also rose by 5.87% on 1 July 2026. If you are on an indexed offer, your kWh price follows these monthly changes.

The PRG is published for four consumption profiles. Higher-consumption profiles pay a slightly lower per-kWh rate:
| Profile | Typical use | Annual consumption | PRG kWh price |
|---|---|---|---|
| Cooking / hot water | Cooking, hot water | 0–6,000 kWh/yr | €0.1783 Prices last certified: October 2026 (source: CRE PRG) /kWh |
| Heating Lowest €/kWh | Heating (individual boiler) | 6,001–300,000 kWh/yr | €0.1456 Prices last certified: October 2026 (source: CRE PRG) /kWh |
CRE Prix Repère (October 2026), single grid for the GRDF area (about 95% of homes). Some suppliers still price by historical zone, and local distributors (Bordeaux, Strasbourg, Grenoble…) have their own grids.

What's on Your Gas Bill?
A French gas bill has three components. Only one of them changes when you switch supplier:
Energy supply
The cost of buying gas on wholesale markets plus the supplier's margin. This is what changes when you switch — the other two components stay exactly the same regardless of who supplies you.
Network access (ATRD)
What GRDF charges for maintaining and using the gas pipes. Set by the regulator — identical for all suppliers. Includes the standing charge (abonnement) on your bill.
Taxes
Three government levies applied to every bill regardless of supplier. Excise and CTA are the same with every supplier; VAT (20%) applies to the whole bill.

Key terms on a French gas bill
| French term | English meaning |
|---|---|
| Abonnement | Fixed monthly standing charge — covers network access |
| Consommation | Consumption charge — kWh used × price per kWh |
| Prix Repère Gaz (PRG) | CRE monthly reference price — the market benchmark |
| Offre indexée | Indexed offer — price tracks the PRG each month |
| Offre à prix fixe | Fixed-price offer — the price per kWh excluding taxes is locked for the contract term; taxes, network charges and, depending on the offer, the subscription can still change |
| PCE | Your gas meter reference number (14 digits) — needed to switch supplier |
