ENGIE at a glance
ENGIE is the successor to Gaz de France (GdF), the state monopoly that supplied gas to every French household for decades. After merging with Suez in 2008, the company rebranded as ENGIE in 2015 and expanded aggressively into electricity retail and renewable energy production. Today it serves over 11 million residential customers across both gas and electricity, making it the second-largest energy retailer in France behind EDF.
ENGIE offers
ENGIE structures its residential catalogue around four main offers, covering both gas and electricity. Gas customers get the Gaz Reference plan, indexed on the government benchmark price which is updated monthly. Electricity customers choose between three options: an indexed plan that follows the regulated tariff (TRV), a fixed-price plan for budget certainty over one to two years, or a green energy option backed by guarantees of origin from renewable sources.

Ranked by price · , Toulouse · Savings vs .
ENGIE's electricity prices tend to sit slightly above the cheapest alternative suppliers (like TotalEnergies or Octopus Energy), but the company compensates with brand reliability, dual-energy convenience, and a large physical network of stores across France.
For gas, ENGIE remains highly competitive as the historical supplier. Its Gaz Reference offer closely tracks the government benchmark, making it a straightforward and transparent choice for gas-only or dual-energy customers.

Pros and cons
ENGIE is well suited to expats and long-term residents who want the simplicity of a single supplier for both gas and electricity, backed by a well-established brand with decades of history. However, it is not the cheapest option on the market, and its complete lack of English-language support is a significant barrier for non-French speakers managing their account independently.
- Dual gas + electricity from one supplier, one bill
- Green energy options with renewable certificates
- Competitive gas prices as historical supplier
- Large physical store network across France
- No English-speaking customer support at all
- Electricity prices higher than smaller alternative suppliers
- Mixed customer service reviews and long wait times

FAQ
No. ENGIE's customer service operates exclusively in French. However, you can call Selectra at 09 74 59 44 32 to speak with an English-speaking advisor who will handle your ENGIE subscription.
Yes. ENGIE is one of the few suppliers offering genuine dual energy contracts covering both gas and electricity on a single bill. As France's historical gas supplier, their gas expertise is a key differentiator.
For gas, ENGIE is typically competitive since it is the incumbent supplier. For electricity, it depends on the offer: indexed plans track the regulated tariff closely, while fixed plans (Elec Tranquillite) lock in a rate that may be higher or lower depending on market timing.
Switching is free and takes about 5 minutes. There is no cancellation fee and no power cut. Your new ENGIE contract starts on the date you choose, and your old supplier is cancelled automatically. Call Selectra at 09 74 59 44 32 for English help.
