When it comes to selecting an electricity supplier in 2026, the market offers more than just a simple choice between power points. The liberalisation of the energy market in 2007 opened the door to genuine competition, transforming the landscape for households across France and beyond. Amongst the array of providers vying for attention, ENGIE stands out with a compelling combination of green credentials, price stability, and award-winning customer service. This comprehensive comparison examines five leading suppliers to help you navigate the often bewildering world of energy contracts and understand what sets ENGIE apart in today's competitive environment.

Engie particuliers
As France's leading green electricity supplier, ENGIE has built a formidable reputation since the energy market opened to competition nearly two decades ago. With a turnover of 73.8 billion euros in 2024 and a presence spanning more than 30 countries, the company operates on a scale that few competitors can match. What truly distinguishes ENGIE, however, is not merely its size but the combination of tangible benefits it delivers to its five million green electricity customers. The supplier has been voted Customer Service of the Year 2026 in the energy supplier for individuals category, a recognition that reflects the dedication of advisors available seven days a week to support households with their energy needs.
Fixed-Price Electricity for Three Years with Green Credentials
The cornerstone of ENGIE's offering lies in its commitment to price stability through fixed-price electricity for three years. This approach shields customers from the volatility that has characterised energy markets in recent years, when wholesale prices soared beyond 200 euros per megawatt-hour during the crisis before settling around 70 to 80 euros per megawatt-hour in 2025. With a kilowatt-hour price of 0.1985 euros and an annual subscription of 183.96 euros, households can anticipate an estimated annual budget of approximately 1,315 euros for a typical consumption of 6,000 kilowatt-hours. Beyond the financial predictability, ENGIE supplies green electricity certified by guarantees of origin, positioning itself as France's foremost provider of renewable power. The company aims to achieve 58 percent green electricity production by 2030 and has set an ambitious target of carbon neutrality by 2045, demonstrating a long-term environmental commitment that extends well beyond marketing rhetoric.
Personalised support and customer satisfaction
Customer service quality remains a decisive factor when choosing an electricity supplier, and ENGIE has invested considerably in this area. The company's advisors are accessible throughout the week, ensuring that support is available when households need guidance on tariff options, consumption profiles, or contractual conditions. For those seeking more tailored assistance, the My ENGIE Appointment service offers personalised support from an energy expert, allowing customers to discuss their specific needs, whether related to the size of their home, electric heating requirements, off-peak usage patterns, electric vehicle charging, or contracted power levels. With a customer satisfaction rating of 4.4 out of 5 on Trustpilot based on more than 12,000 reviews, ENGIE has earned trust through consistent service delivery. The Elec Vert+ option further enhances the green offering by providing 100 percent French green electricity, appealing to those who prioritise domestic renewable sources. Although the company registers 25 complaints per 100,000 contracts with the national energy mediator, this figure remains reasonable within the broader market context and reflects the scale of its customer base rather than systemic service failures.
Totalenergies
TotalEnergies occupies a distinctive position in the French energy market as the third-largest supplier, transitioning from its roots as a petroleum company to offer a diverse range of electricity and gas services. The company has built a customer base of four million households by emphasising competitive pricing and flexible contract options. However, its customer satisfaction rating of 3.5 out of 5 based on more than 1,000 reviews on Trustpilot suggests that service quality remains an area where improvement is needed. The company offers renewable origin guarantees for its electricity and includes 10 percent biogas in its gas supply, reflecting a gradual shift towards greener energy sources as it pursues carbon neutrality by 2050.
Competitive pricing with shorter commitment periods
TotalEnergies structures its pricing to appeal to cost-conscious consumers, with a kilowatt-hour price of 0.1889 euros and an estimated annual budget of approximately 3,157 euros for a 100 square metre home. The company provides fixed-price contracts for one or two years, offering less long-term stability than some competitors but allowing households to reassess their supplier choice more frequently. For a standard 6 kilovoltampere connection, the annual subscription stands at 150 euros, with the Standard Fixe offer providing straightforward pricing at 0.2132 euros per kilowatt-hour. Alternative tariff structures include the Heures Eco option, priced at 0.2516 euros per kilowatt-hour with a slightly lower annual subscription of 149.28 euros, and the more complex Heures Eco+ plan, which features off-peak hours at 0.1884 euros, peak hours at 0.2574 euros, and vigilance hours reaching 1.00 euro per kilowatt-hour. This tiered approach suits households with flexible consumption patterns but requires careful monitoring to maximise savings.
Gas offerings and service considerations
For households requiring both electricity and gas, TotalEnergies presents a comprehensive solution, though the green credentials of its gas supply remain modest compared to dedicated renewable providers. The gas offering includes 10 percent renewable content, notably less than competitors who prioritise biogas injection. Customer service is available by phone and online, with additional services such as electric vehicle charging support and energy efficiency advice forming part of the broader package. The relatively low satisfaction rating highlights challenges in dispute resolution and service responsiveness, factors that potential customers should weigh against the competitive pricing. Contractual conditions allow for flexibility in switching providers without penalties, a standard feature across the liberalised market that ensures households retain control over their energy choices as circumstances and priorities evolve.
Enercoop
Enercoop operates as a French cooperative dedicated exclusively to 100 percent renewable energy, setting itself apart through a citizen-focused model that prioritises environmental integrity over profit maximisation. With 110,000 customers and 64,200 members, the cooperative achieved a turnover of 227 million euros in 2023 whilst maintaining the highest customer satisfaction rating in the market at 4.79 out of 5 based on more than 3,000 reviews. The company purchases electricity directly from French renewable producers, ensuring traceability and supporting the domestic green energy sector. Greenpeace has recognised Enercoop as genuinely green, and the cooperative holds the VertVolt very committed label from ADEME, certifications that underscore its environmental credentials.
Premium pricing for direct renewable sourcing
The cooperative's commitment to purchasing power directly from renewable producers results in higher prices than mainstream suppliers, a trade-off that appeals to environmentally conscious households willing to pay a premium for authenticity. The kilowatt-hour price stands at 0.2531 euros, with an annual subscription of 177.84 euros, yielding an estimated annual budget of approximately 1,621 euros for a standard consumption profile. Enercoop offers the Basic Watt tariff for those on a single-rate meter and the Flexi Watt option for peak and off-peak configurations, the latter priced at 0.2746 euros during peak hours and 0.1895 euros during off-peak periods. These rates reflect the higher costs associated with direct renewable procurement and the cooperative's refusal to compromise on the origin of its electricity supply. For a 70 square metre dwelling, annual costs reach approximately 2,083.90 euros, whilst larger properties of 200 square metres face bills around 5,062.07 euros.
Reliability and customer-focused governance
Beyond pricing, Enercoop distinguishes itself through exceptional reliability and customer satisfaction. The cooperative registers just six disputes per 100,000 contracts with the national energy mediator, the lowest rate in the market and a testament to its transparent governance and responsive service. Members have a voice in the cooperative's direction, fostering a sense of ownership and alignment between the supplier and its customer base. Customer service focuses on education and support, helping households understand their consumption patterns and make informed decisions about tariff options and energy efficiency measures. The cooperative's fixed prices remain stable for the contract duration, though at a level approximately 15 percent higher than the regulated tariff. For those who prioritise environmental impact and wish to support French renewable producers directly, Enercoop offers an unmatched proposition, albeit one that requires a financial commitment beyond what budget-focused suppliers demand.
Edf
EDF remains the historic electricity supplier in France, established in 1946 and still responsible for the regulated tariff known as the Tarif Bleu. With 30 million customers and 41.5 million worldwide, the company operates on a scale that dwarfs most competitors, leveraging a nuclear-heavy energy mix that accounts for 76 percent of its electricity production. The French state owns 100 percent of EDF since 2023, reinforcing its role as a cornerstone of national energy policy. Customer satisfaction stands at 4.6 out of 5 based on more than 45,000 reviews on Trustpilot, reflecting the company's long-standing presence and comprehensive service offerings.
Diverse tariff options and nuclear reliance
EDF's portfolio includes both regulated and market tariffs, with the Tarif Bleu priced at 0.27 euros per kilowatt-hour and an annual subscription of 156.12 euros for a standard 6 kilovoltampere connection. For those seeking fixed-price certainty, the Zen Fixe offer provides electricity at 0.1774 euros per kilowatt-hour with a higher annual subscription of 177.36 euros, yielding an estimated annual budget of approximately 1,189 euros for a household consuming 6,000 kilowatt-hours. The fixed-price commitment extends for two years, offering medium-term stability without the longer guarantees available from some competitors. EDF's reliance on nuclear power means that its green credentials depend heavily on optional tariffs that source electricity from hydroelectric and other renewable facilities. Whilst nuclear energy produces low carbon emissions during operation, it does not qualify as renewable, a distinction that matters to environmentally focused consumers.
Market dominance and service infrastructure
The company's extensive infrastructure and historical position grant it advantages in service delivery and network management, though Enedis, which operates the distribution network across 95 percent of French territory, functions independently of the supplier. EDF's customer service operates through multiple channels, with advisors available to discuss tariff choices, consumption profiles, and billing queries. The company's size and resources enable it to offer a wide range of services, from electric vehicle support to energy efficiency programmes, though the sheer scale of its operations can sometimes result in slower response times compared to smaller, more agile competitors. Green electricity options are available for those who prioritise renewable sources, but these remain secondary to the nuclear-based offering that forms the backbone of EDF's supply. The regulated tariff provides a benchmark for the market, ensuring that households always have a reference point when evaluating alternative suppliers, though the liberalised market has consistently demonstrated that competitive offers can deliver better value and service.
Primeo
Primeo Energie entered the French market in 2013 and has since attracted approximately 170,000 customers through competitive pricing and a focus on renewable energy sourcing. The company operates 232 renewable energy production sites across Europe, generating 1,489 gigawatt-hours of green electricity in 2024. With a customer satisfaction rating of 4.14 out of 5 based on more than 2,400 reviews, Primeo positions itself as a reliable alternative to the larger established suppliers, offering fixed-price contracts with discounts relative to the regulated tariff. The company has built its reputation on transparency and straightforward pricing structures, appealing to households seeking value without sacrificing environmental considerations.
Discounted fixed-price electricity
Primeo's Fixe Eco offer delivers a 15 percent discount on the kilowatt-hour price compared to the regulated tariff, translating to a rate of 0.1704 euros per kilowatt-hour with an annual subscription of 196.80 euros. For a typical household consuming 6,000 kilowatt-hours annually, the estimated budget stands at approximately 1,219 euros, positioning Primeo amongst the more affordable suppliers in the market. The fixed-price commitment extends until 31 July 2027 in some instances, though standard contracts typically run for one year with the option to renew. Green electricity options are available for an additional two euros per month, allowing environmentally conscious customers to enhance their renewable credentials without a substantial financial burden. The company's relatively low dispute rate of 19 complaints per 100,000 contracts suggests effective customer service, though this figure remains higher than the most reliable cooperatives.
Customer service and contract flexibility
Customer service at Primeo operates Monday through Friday from 9am to 5pm, a more limited schedule than some competitors who offer seven-day availability. This constraint may pose challenges for households requiring support outside standard working hours, though the company's digital channels provide alternative contact methods. Contractual conditions mirror industry standards, with no penalties for switching suppliers and straightforward termination processes that ensure customers retain flexibility. The company's emphasis on renewable sourcing and competitive pricing appeals to a specific segment of the market, particularly those who value environmental responsibility alongside affordability. With over 125 years of experience in the energy sector through its parent company, Primeo brings historical expertise to the modern liberalised market, blending tradition with innovation to meet contemporary consumer expectations. For business customers, the company offers SME-PMI contracts with commitments ranging from one to four years, providing longer-term stability for commercial operations whilst maintaining competitive pricing structures tailored to professional consumption profiles.
