Gas up 6.6% from 1 November: who is affected and how to check your contract

On 12 October 2026 the Commission de régulation de l'énergie (CRE) announced that from 1 November 2026 the prix repère de vente de gaz (PRVG) will rise by 6.6% including tax, from €182.88 to €194.90 per MWh TTC. It already went up 6.3% in October. CRE estimates that customers whose contract is tied to the prix repère will pay on average about €12 TTC more for November. CRE gives the reason as higher prices on wholesale gas markets in September compared with August.

Not everyone is affected, though. What matters is the kind of contract you have.

What the prix repère is

France no longer has a regulated gas tariff (TRVG): it ended on 30 June 2023. Since then CRE has published a monthly prix repère, a benchmark showing what it costs a supplier, on average, to supply a household. You cannot sign up to the prix repère: it is not an offer, but a yardstick for comparing suppliers' offers.

The prix repère has three parts: the gas supply itself (fourniture), transport and storage (acheminement), and taxes (TVA, accise, CTA). Only the first part moves each month, following wholesale prices, and only that part changes on 1 November.

Who is affected

• A contract with a price indexed to the prix repère: your price per kWh will follow it.
• A fixed-price contract (prix fixe): this rise does not affect you while the fixed price runs. According to CRE, around 40% of household gas customers had fixed-price contracts at the end of 2025.

If you rent a home with an individual gas boiler or cooker and the supply contract is in your name, check the terms of your contract to see whether the price is fixed or tied to the prix repère. If gas is included in your charges and paid through the landlord or building manager, you did not sign the contract, and the question is for them.

The new figures by use

CRE publishes separate benchmarks for "cooking and hot water" and for "heating". From 1 November 2026, for the GRDF network (around 95% of household customers), the average figures including tax are:

• cuisson / eau chaude: €0.19027 per kWh, standing charge €152.46 a year;
• chauffage: €0.15760 per kWh, standing charge €360.79 a year.

Transport and storage costs depend on location, so CRE also publishes a range: for heating, €0.14798 to €0.17639 per kWh. If you use 4–6 MWh a year, suppliers may put you in either category, and CRE advises comparing offers on your annual consumption. Customers of local distribution companies (not GRDF) should look at CRE's separate grid for their area.

How to compare and switch supplier

The médiateur national de l'énergie runs a free, independent comparison tool: comparateur-offres.energie-info.fr. According to the médiateur, switching:

• is free for households: you cannot be charged simply for changing supplier (only a special meter-reading visit is chargeable, around €30);
• ends your old contract automatically on the day the new one starts; you do not need to write to the old supplier;
• does not cut off your gas: supply continuity is ensured by the network operator;
• has no minimum commitment period; you will need your 14-digit PCE number, which is on your bill.

A common mistake is to cancel the old contract first and then look for a new one. Do it the other way round: sign the new contract, and the new supplier handles the rest. If you sign by phone, online or on the doorstep, you have 14 days to withdraw.

What next

CRE estimates that if conditions stay roughly stable until the end of the year, the 2026 annual gas bill will be about 11% (around €135 TTC) higher than in 2025. The prix repère is recalculated every month, so CRE will publish the December figure in November.
