Alternative Energy Suppliers in France 2026: Full Guide

1. What is an alternative energy supplier?

An alternative supplier is any energy provider other than the historical supplier of the segment. On electricity, the historical supplier is EDF: every other player (TotalEnergies, Engie, Octopus, Enercoop, Mint and so on) is an alternative supplier. On gas, the roles are reversed: Engie (formerly GDF) is the historical supplier, and every other provider, including EDF, is alternative.

The distinction is legal. Only the historical supplier can sell the regulated tariff (TRV), set by the public authorities on a proposal by the energy regulator (CRE). Alternative suppliers offer only market contracts at freely set prices.

4. Advantages and disadvantages

5. Expats: which suppliers are most accessible?

If you have recently moved to France and your French is still in progress, several alternative suppliers are easier to handle as a non-native speaker. You will still need a French postal address, a French or SEPA-compatible bank account (IBAN), and an active electricity / gas connection. Identity verification typically requires a passport, visa or residence card.

6. How to choose the right supplier

Five essential criteria

7. Five-step switching procedure

Switching your electricity or gas supplier in France is free, with no outage and no technical intervention. Your new supplier takes care of every step, including cancelling the previous contract.

1. 1

   Analyse your consumption

   Note your annual consumption in kWh (visible on your bill) and your subscribed power in kVA (3, 6, 9 or 12 kVA depending on home size).

2. 2

   Compare offers

   Enter postcode, consumption and power on the Mediator's comparator (energie-info.fr) or on the simulator of pre-selected suppliers.

3. 3

   Sign up online with your PDL

   Prepare your 14-digit PDL number (visible on bill or Linky display), your IBAN and a meter reading. Sign-up typically takes 5 to 10 minutes.

4. 4

   Let the new supplier handle cancellation

   No action is required with the previous supplier. The previous contract is cancelled automatically at the date of the switch.

5. 5

   Activation within 21 days maximum

   The switch is effective on the agreed date (usually 1 to 2 weeks with Linky), with no outage and no on-site visit. You receive a final closing invoice from the previous supplier within 4 to 6 weeks.

8. Bankruptcy and supplier of last resort

Failures of alternative suppliers are rare but possible. The 2021-2022 energy crisis saw several players exit the market: Hydroption (December 2021), Bulb France / Vivvo (2022), Cdiscount Énergie (stopped commercialisation in 2021), Leclerc Énergies (2022). In every case, supply continuity was guaranteed.

The supplier-of-last-resort mechanism

The French Energy Code (articles L.333-3 and R.333-15) requires the energy regulator (CRE) to designate one or more suppliers of last resort through a public tender. If a supplier fails, customers are automatically transferred, with no outage and no required action. The supplier of last resort applies a regulated price during the transition period (up to 6 months), during which the customer is free to sign up with any other supplier.

9. Green offers and Guarantees of Origin

An offer is called "green" when the supplier buys, for every MWh consumed by the customer, a Guarantee of Origin (GO) certificate proving that an equivalent volume of renewable electricity has been injected into the European grid. The registry is run by EEX and traced via Powernext (designated by France's energy directorate DGEC).

The ADEME VertVolt label

To help consumers tell genuine green from marketing, ADEME created the VertVolt label (refreshed yearly), which distinguishes:

• "Very engaged" offer: 100% renewable + at least 25% sourced from small producers or social economy
• "Engaged" offer: electricity and GOs purchased jointly from a renewable producer (coupled sourcing)

Several alternative suppliers (Enercoop, Plüm, Ilek, Mint, Octopus, Ekwateur, Ohm) are labelled on selected offers. The full 2026 ranking is published on librairie.ademe.fr.

10. Common mistakes to avoid

French electricity market in figures

Since the residential market was fully opened on 1 July 2007, alternative suppliers have steadily gained share of the residential segment, although EDF remains the largest player thanks to its regulated tariff.

EDF's Tarif Bleu remains the benchmark on which all indexed market offers are set. To understand how it works, see our guide on the regulated electricity tariff. To optimise your bill around peak demand, see EDF Tempo or how to reduce your energy consumption. For gas, see our gas provider comparison.
