Best Energy Providers in France (2026)

Which energy suppliers are best in France?

Ten suppliers stand out in October 2026, each for a different reason. Prices below are for a 6 kVA Base electricity contract and, for gas, a heating profile; annual costs use the 4,287 kWh reference profile of a two-person flat without electric heating. Every supplier delivers over the same Enedis and GRDFgrids, so reliability is identical. What differs is price, freeze length, green sourcing and service. Ratings are our editorial scores for each supplier's lead offer.

Prices from the CRE barème of 1 August 2026 and supplier grids relayed by JeChange, Kelwatt, Selectra, Hello Watt and MoneyVox, checked in October 2026 unless a card gives an earlier date. Trustpilot scores and Médiateur referral rates are October 2026 figures. Annual costs are our calculation: kWh price times consumption, plus the standing charge. Check the live figure on the official comparator before you sign.

Which energy supplier fits your situation?

The cheapest offer for one home can be the wrong one for another. A small studio pays mostly standing charge, an EV owner pays mostly night kWh, and a reader in Grenoble or Metz has a different default supplier. The table matches common situations to the offer that wins and the runner-up, from our October 2026 scenario research.

Is Primeo really the cheapest electricity supplier?

Primeo Énergie has the lowest kWh price checked in October 2026, 16.74 c€, but its standing charge is €198.96, €8.64 a year above the Tarif Bleu. ekWateur charges 17.53 c€ with the regulated €190.32 standing charge. Which one is cheaper on the total bill depends on your consumption and on whether you want green power, which Primeo sells as a €2 a month option.

On these grids, standard Primeo beats ekWateur above about 1,100 kWh a year, by €25 at the reference profile. Like for like on green power, the crossover moves to about 4,130 kWh: below it ekWateur is cheaper, above it Primeo with its green option wins, and at 4,287 kWh the two are €1.23 apart. Some comparator write-ups put ekWateur about €10 a year ahead on the total bill; we could not reproduce that from the published October grids. Two offers look cheaper on paper, OHM's Extra Eco (16.40 c€, July 2026 grid, not guaranteed) and Alpiq's Électricité Stable (16.73 c€, February 2026 grid), but their figures predate October, so check them on the official comparator.

Which energy suppliers left or merged in 2026?

Vattenfall France left the household market in July 2026. Its roughly 175,000 customers moved automatically to Alterna énergie, the cooperative that about 50 local utilities, led by Sorégies, use to sell outside their home zones. Customers kept their supply without doing anything, and they remain free to switch elsewhere at no cost.

• Wekiwi was absorbed by Plenitude (Eni) on 2 June 2026 and no longer sells separately. The migration caused service friction in mid-2026.
• The ARENH scheme, which gave suppliers access to cheap EDF nuclear power, ended on 31 December 2025. Small web-only suppliers without their own production raised prices or folded in early 2026.
• Primeo Énergie is active and priced lowest per kWh, despite a forum reputation dating from its 2022-23 difficulties.
• OHM Énergie survived 2022 and now rates 4.7/5 on Trustpilot over 10,700 reviews, with 25 Médiateur referrals per 100,000 contracts.
• Sowee, an EDF brand, had no 2026 offer grid we could find; it appears closed to new customers, which we could not confirm.

The lesson forums draw is to favour suppliers backed by production or a public utility, such as GEG, Gaz de Bordeaux and Alterna. The household risk is smaller than it sounds: when Vattenfall left, its customers kept their supply and were moved without doing anything. The CRE tracks these market moves in its quarterly retail observatory.

How do you choose an energy supplier in France?

Choosing a supplier starts with your annual consumption in kWh, shown on any past bill or in your Linky account. Below about 3,000 kWh, the standing charge weighs most and savings stay under about €100 a year; above it, the kWh price drives the bill. Every supplier delivers over the same Enedis and GRDF grids, so a switch never changes your meter or your reliability. Compare on the Médiateur national de l'énergie comparator, the only one that lists every offer.

1. Step 1: Note your consumption, subscribed power (kVA) and option (Base or heures creuses).
2. Step 2: Decide what matters: lowest price, a dated freeze, French green sourcing, or English support.
3. Step 3: Rank offers on the official comparator, then read the supplier's price sheet for the exact grid.
4. Step 4: Check service data: among the suppliers we track, Médiateur referrals per 100,000 contracts run from 6 (Enercoop) to 45 (ekWateur).
5. Step 5: Sign online with your PDL/PRM; the new supplier closes the old contract for you.

What types of energy offers exist?

French energy offers fall into four types, and each one names what it freezes. A prix fixe offer freezes the kWh price before tax for one to three years. A prix indexé offer tracks the Tarif Bleu at a stated discount. An offre verte adds renewable guarantees of origin. Time-of-use options price night or low-demand days lower. The regulated gas tariff was abolished on 1 July 2023, so gas offers are fixed or indexed on the CRE benchmark.

• Prix fixe: Primeo (to 31 December 2027), Octopus (2 years), Gaz de Bordeaux and Engie (3 years). Taxes and the TURPE network charge still move.
• Prix indexé: TotalEnergies Access (8% off), Mint Énergie (11% off before tax). The price follows every Tarif Bleu revision.
• Offre verte: backed by guarantees of origin. The ADEME VertVolt label marks the stronger claims: Enercoop and GEG hold its top grade, Octopus and Ilek its first grade, and Alterna also carries the label.
• Heures creuses, Tempo and EV tariffs: Octopus Go at 13.35 c€ across 8 night hours, Ilek at 10.59 c€ from 2 a.m. to 6 a.m., EDF Tempo with 300 cheap days and 22 red days at 72.95 c€ peak.

How much does energy cost in France?

The regulated Tarif Bleu costs 20.01 c€/kWh plus €190.32 a year (Base, 6 kVA, since 1 August 2026), so a two-person flat using 4,287 kWh pays €1,048 a year. The best market offers cut that by €106 to €132 at the same use. Our energy price research lists 17 offers with their annual totals.

What affects your bill

• Meter power (kVA): the Tarif Bleu standing charge runs from about €145.56 a year at 3 kVA to €238.56 at 9 kVA.
• Consumption: savings from switching grow with use, from about €70 a year at 2,400 kWh to about €345 at 10,800 kWh (our calculation, Primeo against the Tarif Bleu).
• Network and taxes: about two thirds of the bill, identical at every supplier. TVA has applied at 20% to the standing charge since 1 August 2025.
• Green sourcing: from free (Mint, ekWateur) to €2 a month (Primeo) or a deliberate premium of about €130 to €160 a year (Enercoop at 5,000 kWh).
• Gas: at 11,200 kWh, fixed gas runs from about €1,519 a year (Alterna) to €2,102 (Ilek's 100% biogas), against €1,991 at the October benchmark.
