Gas subscription prices: how to find them and why do they change?

Did you know that gas is the leading heating source in France, used by 35.8%(1) of households? If you are among these users, you have probably already wondered about the cost of gas subscriptions. How can you find out the price? And what factors influence it? Let’s take a closer look.

How can you find the price of your gas subscription?

Would you like to know the price of your gas subscription for your home? There are three ways to do so.

The first is to log in to your online customer account, where you will find all the information related to your gas supply. You can also check your gas bill, which details the costs associated with your subscription. The gas contract you signed with your supplier also includes this information.

Have you noticed?

To clearly understand the price of your gas subscription, it is important to distinguish between the fixed part and the variable part of your bill.

• The fixed part represents the amount you pay regularly (monthly or quarterly), according to your contract terms, regardless of your gas consumption. It covers all costs related to access to the service (maintenance of pipelines managed by network operators—GRDF in France—maintenance of your gas meter, administrative services related to contract management, as well as fixed taxes and contributions).

• The variable part depends on your consumption in cubic meters, converted into kilowatt-hours (kWh) by your supplier using the applicable conversion coefficient. The more gas you consume, the higher this part of your bill will be.

A duty to inform consumers

In France, all gas suppliers, including ENGIE, are free to set their own subscription prices. However, they are legally required to provide consumers with clear and detailed information about their tariffs and the general terms and conditions of their gas offers.

Why do subscription prices vary from one consumer to another?

You may have noticed that subscription prices vary depending on your location or your level of consumption and that is perfectly normal. Here is why.

The impact of your tariff zone on your gas subscription cost

To determine the cost of your gas subscription, you must first consider your gas tariff zone.

Transporting gas from production and/or storage sites to consumers involves costs. Logically, the further your home is from storage centers, the higher the logistical costs to deliver gas to your property. To reflect these differences, France is divided into several tariff zones.

There are six zones in total: zone 1 is the closest to distribution centers, while zone 6 corresponds to the most remote areas.

Therefore, if you live in a more remote zone (for example, zone 5 or 6), your gas subscription will be slightly more expensive than if you lived in zone 1 or 2.

Variations due to your consumption class

The amount of gas you consume annually also impacts your subscription price. To tailor their pricing (both subscription and kWh price), gas suppliers rely on what are known as consumption classes (or consumption profiles).

There are 4 consumption classes, and you will automatically be assigned one based on your usage:

• Base class, for low consumers (annual consumption below 1,000 kWh), typically those who use gas only for cooking.

• B0 class, for households using gas for cooking and hot water, but not for heating. Annual consumption ranges between 1,000 and 6,000 kWh.

• B1 class, corresponding to annual consumption generally between 6,000 and 30,000 kWh. These users rely on gas for heating as well as cooking and hot water.

• B2i class, for very high residential consumers (often in shared buildings), with consumption above 30,000 kWh and up to 300,000 kWh per year.

While these classes exist, they are not always explicitly displayed. In practice, pricing grids often group them into simpler categories such as “cooking” or “heating,” depending on price differences. The key takeaway is that the higher your consumption profile, the higher your gas subscription cost. This is logical and comparable to electricity subscriptions, where higher power needs result in higher subscription prices.
