The best gas supplier based on your budget
Although price should not be the only factor when choosing your gas supplier, your budget is of course a key consideration especially in a context of high volatility and rising gas prices.
Is your budget tight? Consider a fixed-price offer, which allows you to benefit from a stable reference price over a defined period. However, be mindful of overly attractive offers and check the conditions carefully, such as how long the price is guaranteed.
Alternatively, you can choose an indexed gas offer, where prices follow market fluctuations. This option may be suitable if you expect gas prices to decrease in the coming months.
For example, ENGIE offers a plan with a price per kWh closely aligned with the French wholesale gas market.
The best supplier based on your usage intensity and consumption level
Choosing the best gas supplier also depends on how much gas you use and your consumption profile.
If your gas consumption is moderate, it may be worth looking into offers specifically designed for low-consumption households.
You should also pay attention to the subscription fee: if your consumption is low or moderate, it can be advantageous to choose a supplier with a lower subscription cost, even if the price per kWh is slightly higher.
This is particularly relevant if you are looking for a cost-effective supply contract for a second home in France.
On the other hand, if you use gas for heating, hot water, cooking, and/or if your home is large, your gas consumption is likely to be significant. In this case, it is generally better to choose a supplier with a lower price per kWh, even if the subscription fee is less competitive.
In any case, do not base your decision solely on price. Available options, the services offered by the supplier, and their commitment to the energy transition are also important factors to consider.
The best gas supplier for simplified management
Choosing a gas supplier offering dual energy deals
If you want to simplify the management of your energy contracts, it may be worth choosing a supplier that offers dual deals, combining electricity and gas into a single bill, with one point of contact if needed.
This is the case with ENGIE, which offers a dual plan tailored to your electricity and gas needs, with a market-indexed price: the Duo Adapt 1-year offer. Two energies combined into one contract simplicity at its best!
Choosing a gas supplier with responsive customer service
The reliability and quality of customer service is an important criterion when choosing your gas supplier. In case of an issue, it is essential to be able to rely on a responsive and efficient support team.
That is why it is important to check the supplier’s reputation before committing: is their customer service easy to reach? Is it based in France? Are the advisors attentive and helpful?
To get a clearer picture, read online customer reviews and check the complaint rate published by the Médiateur national de l’énergie (the French national energy ombudsman, an independent public authority).
As an example, ENGIE customer service can be reached every day (including Sundays) via phone, chat, chatbot, and more.
Does the supplier offer maintenance services?
Additional services can also make a difference when choosing between suppliers. For greater convenience, you may opt for a supplier that offers maintenance services for your gas boiler.
ENGIE offers a package covering the mandatory annual maintenance visit, as well as additional services such as breakdown assistance. It is worth noting that maintaining your gas boiler is a legal requirement in France, as set out in the decree of 15 September 2009 on annual boiler maintenance.
Choosing a supplier for its consumption support services
Finally, some suppliers stand out through the support they provide to help you manage your energy consumption more responsibly.
The Ma Conso service, which allows you to track and manage your consumption in kWh and euros, as well as the Mon Alerte service, which notifies you when your consumption is higher than expected, are included in ENGIE contracts.
Mon Programme pour Agir by ENGIE also encourages customers to better manage their energy use: points (called KiloActs) are awarded in return. These points can then be invested in projects supporting the energy transition or exchanged for items that help you consume more efficiently.
Best gas supplier: key takeaways
Choosing the best gas supplier primarily depends on your budget. If your budget is tight, prioritize a fixed-price offer to benefit from a stable reference price, while carefully checking the terms and conditions.
In addition, if your consumption is moderate, choose a supplier with a low subscription fee, whereas if your consumption is high, opt for a supplier offering a lower price per kWh.
If you are environmentally conscious, choose a supplier offering green gas solutions or offsetting the CO₂ emissions linked to your gas consumption.
Make sure the supplier covers your geographical area in France, and consider choosing a supplier offering dual energy deals to simplify the management of your contracts.
Finally, choose a supplier with responsive and efficient customer service, offering boiler maintenance services and consumption support tools for more responsible energy use.
What is the best gas supplier in 2025 for an individual customer?
There is no single “best gas supplier” as such, but there is a best gas supplier for you. The right choice depends on your priorities: price, customer service quality, environmental commitment (green gas), or specific services (boiler maintenance, dual energy offers).
Fixed or indexed price: which option should I choose based on my consumption profile?
A fixed price is ideal if you are looking for maximum budget stability. It protects you against market price increases (but not against tax changes). An indexed price should be chosen if you expect prices to fall and are willing to follow market fluctuations.
What is the Prix Repère CRE and how can I use it to compare offers?
The Prix Repère de Vente du Gaz (PRVG), published monthly by the CRE (Commission de Régulation de l’Énergie), is a neutral benchmark that replaced the regulated gas tariff, which was removed in 2023. It is essential for transparently comparing market offers and ensuring your supplier provides competitive pricing.
How do I switch gas suppliers: timeframe, interruption, fees?
Switching is free of charge, with no commitment and no termination fees. There is no service interruption. The process takes only a few days, and your new contract starts on the date you choose.
Green gas / biomethane: what is it, and what is the impact on my bill and the environment?
Green gas, or biomethane, is produced locally in France from waste. Its impact on your bill is minimal or even neutral in some offers but its environmental impact is significant. It helps reduce the carbon footprint of your natural gas consumption.
How is the gas price calculated (subscription vs kWh, tariff zone, classes B0/B1/B2i)?
The final price consists of two parts: the subscription (fixed part) and the price per kWh (variable part). The subscription varies depending on your consumption class (Base, B0, B1, B2i, etc.) and your geographical tariff zone.
Who manages the network and interventions (GRDF)?
The gas distribution network is managed by GRDF (Gaz Réseau Distribution France), which operates independently from your supplier (such as ENGIE). GRDF handles connections, network repairs, and meter maintenance.
Moving home: what steps should I take to activate gas in my new property?
- Take out a new gas contract (you are responsible for terminating the one for your previous home).
- Choose a start date for the supply.
- Pay the commissioning fee charged by GRDF.
Dual electricity + gas offers: benefits and points to watch out for?
A dual offer simplifies management with a single contract and one point of contact. However, make sure the offer is competitive for both electricity and gas—not just one of them.
Collective gas heating: do I have an individual contract?
No. If your heating system is collective, it is also billed collectively. The gas contract is signed by your building’s property manager (syndic). You do not have an individual contract and cannot choose your supplier. However, you can raise the topic with your syndic to consider a more competitive contract.
What support is available in case of financial difficulty (Chèque énergie)?
The Chèque Énergie is a government subsidy paid to eligible households in France to help cover energy bills.
What protections exist in case of a dispute (Médiateur national de l’énergie)?
If a dispute with your supplier remains unresolved, you can refer the case free of charge to the Médiateur national de l’énergie.
