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 is published for four consumption profiles. Higher-consumption profiles pay a slightly lower per-kWh rate:
| Profile | Typical use | Annual consumption | PRG kWh price |
|---|---|---|---|
| Base | Cooking only | < 1,000 kWh/yr | €0.1432 Prices last certified: janvier 2027 (source: CRE PRG) /kWh |
| B0 | Cooking + hot water | 1,000–6,000 kWh/yr | €0.1541 Prices last certified: janvier 2027 (source: CRE PRG) /kWh |
| B1 Lowest €/kWh | Heating (individual boiler) | 6,000–30,000 kWh/yr | €0.1206 Prices last certified: janvier 2027 (source: CRE PRG) /kWh |
| B2i | Collective / shared heating | > 30,000 kWh/yr | ≈€0.1206 Prices last certified: janvier 2027 (source: CRE PRG) /kWh |
CRE Prix Repère (janvier 2027), zone 1 (Paris region). Zone affects kWh price by up to ~6% depending on your location.
What Will I Pay for Gas in France?
Your annual bill depends almost entirely on what you use gas for. Select your situation:
Typical annual consumption
PRG kWh price
Prix Repère CRE — janvier 2027
PRG (janvier 2027), zone 1. Competitive offers are typically priced below the PRG. Actual bill depends on your tariff zone and insulation.

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. They cannot be reduced by switching — but they're identical whether you're with an expensive or cheap provider.
The three gas taxes in France
| Tax | What it funds | Rate |
|---|---|---|
| Accise sur le gaz (formerly TICGN) | Public energy services, biogas incentives | €16.39/MWh |
| CTA | Pension rights of energy industry workers | 4.71% of network charge |
| TVA (VAT) | General government revenue | 20% on all charges (since Aug. 2025) |
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 — rate locked for the contract duration |
| PCE | Your gas meter reference number (14 digits) — needed to switch supplier |
