The domestic energy market in 2026 presents a complex landscape for households seeking value, reliability, and environmental responsibility from their gas suppliers. With around 40 electricity suppliers and 23 gas suppliers now active across the nation, the liberalisation of the energy market has fundamentally reshaped how consumers approach their energy choices. In this context, ENGIE remains a prominent figure, competing against newer entrants such as Ekwateur, Octopus Energie, Enercoop, and Primeo. Understanding how these gas suppliers stack up in terms of pricing, customer service, environmental commitment, and contract flexibility is essential for making an informed decision in 2026.

Engie particuliers
ENGIE has long been a cornerstone of the domestic energy sector, and in 2026 it continues to serve millions of customers with a broad portfolio of gas and electricity offerings. The company aims for carbon neutrality by 2045 and has made significant strides in integrating green gas into its contracts, with 5% green gas included as standard. ENGIE has been awarded Customer Service of the Year 2026, reflecting its commitment to maintaining high standards of support and responsiveness. This recognition underscores the importance of customer service in an increasingly competitive market where dispute rates and satisfaction scores are scrutinised by households looking for reliable energy partners.
Pricing and contract structure
ENGIE's gas offerings are structured around fixed-price contracts, with the flagship Gaz Référence 3 ans contract priced at 0.10232 euros per kilowatt-hour. This fixed gas price for 3 years provides households with valuable price stability, shielding them from the volatility that has characterised wholesale energy prices in recent years. Between 2021 and 2025, gas prices surged by approximately 120 percent, though they began to decline in May 2025. In this context, locking in a fixed rate offers a safeguard against future price increases, a factor that has become central to household budgeting. For a typical consumption of 13,450 kilowatt-hours per year in zone one, the estimated annual cost with ENGIE is around 1,747 pounds. The annual subscription fee complements this per-unit pricing, contributing to a comprehensive cost structure that households can plan around. By offering a three-year commitment, ENGIE enables customers to benefit from long-term predictability, which is particularly valuable given the energy price increases that have affected millions of homes in recent years.
Customer satisfaction and service quality
Customer satisfaction is a critical differentiator among gas suppliers, and ENGIE's performance in this area is noteworthy. The company has a customer rating of 4.38 out of 5, based on over 24,600 reviews, which places it in a strong position relative to many competitors. However, the dispute rate of 25 per 100,000 contracts indicates that there is room for improvement in handling customer complaints. Despite this, the recognition as Customer Service of the Year 2026 highlights ENGIE's efforts to address issues promptly and maintain open channels of communication. The company's customer service infrastructure is designed to support a diverse customer base, with multiple contact methods and accessible support hours. This focus on customer service is complemented by initiatives such as MonProgrammepourAgir, which rewards energy savings and encourages households to adopt more efficient consumption habits. For domestic customers, the combination of responsive support, clear billing, and proactive engagement makes ENGIE a compelling choice, particularly for those who value stability and a long-standing reputation in the market.
Ekwateur
Ekwateur has carved out a distinct niche in the domestic energy market by positioning itself as a champion of 100 percent renewable energy and digital innovation. Founded in 2015, the company has grown to serve approximately 130,000 customers by 2023, with a business model that prioritises environmental commitment and a fully digital customer experience. Ekwateur's offerings include both electricity and gas, with options that blend traditional natural gas with biomethane, providing households with a pathway to reduce their carbon footprint. The company's emphasis on green energy is reflected in its recognition as the fifth-ranked company in a professional assessment of environmental commitments, underscoring its dedication to sustainability.
Renewable energy and pricing
Ekwateur offers a gas contract that includes either 100 percent natural gas or an 85 percent natural gas and 15 percent biomethane blend, giving customers flexibility in aligning their energy consumption with their environmental values. The electricity offer is priced at 0.2042 euros per kilowatt-hour, with a fixed price for one year, though the gas pricing varies depending on the selected blend. For a typical 100 square metre house, the estimated annual cost for electricity is around 3,759 pounds, which is higher than some competitors but reflects the premium associated with renewable energy sourcing and digital service delivery. Ekwateur's commitment to green gas and renewable electricity is supported by guarantees of origin and partnerships with renewable energy producers, ensuring that the energy supplied is traceable and genuinely low-carbon. The company's pricing model, while not the cheapest on the market, appeals to households that prioritise environmental impact over upfront cost savings. The one-year fixed price offers some protection against short-term market fluctuations, though it lacks the extended stability provided by longer-term contracts such as those offered by ENGIE.
Digital approach and customer experience
Ekwateur's fully digital approach sets it apart from traditional energy suppliers. The company operates without physical branches, relying instead on a robust online platform and mobile app to manage customer accounts, track energy consumption, and provide support. This digital-first model allows Ekwateur to keep operational costs lower and pass some of these savings on to customers, though the overall pricing remains competitive rather than market-leading. Customer reviews reflect a mixed experience, with a rating of 3.9 out of 5 from 479 reviews, indicating satisfaction among some users but also highlighting areas where the digital model may not suit all households. The customer service team, based in Amiens, is accessible through online channels, and the company has made efforts to ensure that support is responsive and helpful. However, the absence of in-person service centres may be a drawback for customers who prefer face-to-face interactions or who require assistance with complex issues. For tech-savvy households that value convenience and environmental credentials, Ekwateur offers a forward-thinking alternative to more established suppliers.
Octopus energie
Octopus Energie, a British company that expanded into France, has quickly gained traction in the domestic energy market by combining competitive pricing, renewable energy commitments, and a strong focus on customer satisfaction. By 2025, Octopus Energie had attracted around 600,000 customers in France, supported by its proprietary Kraken technology platform, which enables efficient customer management and dynamic pricing options. The company's approach emphasises transparency, innovation, and a commitment to renewable energy, with its electricity offer bearing the VertVolt label, which certifies high environmental standards.
Competitive pricing and fixed contracts
Octopus Energie offers an Eco-conso Fixe electricity contract priced at 0.1862 euros per kilowatt-hour, with an estimated annual budget of 1,249 pounds for a household consuming 6,000 kilowatt-hours per year. For gas, the Eco-conso Gaz offer is priced at 0.09466 euros per kilowatt-hour, making it one of the more affordable options available in 2026. This competitive pricing is complemented by fixed-rate contracts that provide stability and protection against market volatility. The company also offers a gas blend that includes 10 percent French biogas, allowing customers to support domestic renewable energy production while benefiting from cost-effective pricing. The combination of low per-unit prices and transparent billing makes Octopus Energie an attractive option for households seeking to minimise their energy costs without compromising on service quality or environmental responsibility. The company's pricing strategy is designed to appeal to a broad audience, from budget-conscious families to environmentally aware consumers who appreciate the integration of biogas into the supply mix.
Customer satisfaction and dispute resolution
Octopus Energie has achieved a customer rating of 4.79 out of 5, based on over 38,700 reviews, which places it among the highest-rated suppliers in the market. This strong performance is further supported by a low dispute rate of 13 per 100,000 contracts, indicating that the company is effective in resolving issues and maintaining customer trust. The Kraken platform underpins this success by enabling seamless communication, accurate billing, and proactive customer engagement. Octopus Energie's digital infrastructure allows customers to monitor their energy consumption in real time, participate in demand-response programmes, and access support through multiple channels. The company's commitment to customer satisfaction is reflected in its policies and practices, which prioritise transparency and fairness. For households that value both affordability and high-quality service, Octopus Energie represents a compelling alternative to traditional suppliers, offering a modern approach to energy provision that is well-suited to the needs of 2026.
Enercoop
Enercoop stands out in the domestic energy landscape as a cooperative supplier dedicated to 100 percent renewable energy sourced from local producers. With 112,000 customers and 64,200 members, Enercoop operates as a citizen-led organisation that prioritises ethical practices, transparency, and community engagement. The company's electricity is certified with the VertVolt label, which denotes a high level of commitment to renewable energy, and its energy mix includes 70 percent wind, 16 percent solar, and 14 percent hydroelectric power, all sourced from within France. Enercoop does not offer gas to individual customers, focusing exclusively on green electricity, which limits its appeal to households seeking a dual-fuel supplier but reinforces its commitment to renewable generation.
Pricing and environmental commitment
Enercoop's electricity is priced at 0.2531 euros per kilowatt-hour under the Basic Watt offer, with an estimated annual cost of 1,621 pounds for a household consuming 5,700 kilowatt-hours per year. This pricing is higher than many competitors, reflecting the premium associated with sourcing energy exclusively from local renewable producers and maintaining a cooperative business model. The annual subscription fee of 177.84 pounds contributes to the overall cost, which is justified by the company's commitment to supporting French renewable energy infrastructure and ensuring that every kilowatt-hour consumed is traceable to a specific renewable source. Enercoop's environmental commitment extends beyond the energy mix to encompass its governance structure, with members having a say in strategic decisions and the company's direction. This democratic approach resonates with households that value transparency, community involvement, and a direct connection to the energy they consume. While the price per kilowatt-hour is higher than that of suppliers such as ENGIE or Octopus Energie, the value proposition lies in the assurance of genuine renewable energy and the opportunity to support a cooperative model that prioritises social and environmental goals over profit maximisation.
Customer experience and dispute rates
Enercoop has achieved a customer rating of 4.79 out of 5, based on over 3,000 reviews, which is among the highest in the market. The company's dispute rate of 6 per 100,000 contracts is the lowest of all major suppliers, reflecting its effectiveness in customer service and complaint resolution. This strong performance is a testament to Enercoop's focus on ethical practices, clear communication, and responsive support. The cooperative structure means that customer concerns are taken seriously and addressed within a framework that values member input and collective decision-making. Enercoop's customer service is accessible through multiple channels, and the company places a strong emphasis on education and engagement, helping households understand their energy consumption and the impact of their choices. For customers who prioritise environmental and social responsibility, and who are willing to pay a premium for the assurance of genuinely renewable energy, Enercoop offers a unique and compelling proposition that aligns energy consumption with personal values.
Primeo
Primeo Energie, a subsidiary of a Swiss group, has established a presence in the domestic energy market by offering competitive electricity pricing and a focus on customer service. With approximately 170,000 customers across France and Switzerland, Primeo has built a reputation for reliability and value, particularly among households seeking fixed-price contracts that provide protection against market volatility. The company operates over 200 renewable energy sites and supplied 1,489 gigawatt-hours of renewable energy across Europe in 2024, demonstrating its commitment to sustainable energy production. However, Primeo does not currently offer gas contracts to individual customers, focusing instead on electricity and serving the business sector.
Electricity pricing and contract options
Primeo's flagship offer, the Fixe Eco -15%, is priced at 0.1704 euros per kilowatt-hour, representing a 15 percent discount on the per-unit price compared to the regulated tariff. For a household consuming 6,000 kilowatt-hours per year, the estimated annual cost is 1,219 pounds, making Primeo one of the more affordable options in the market. The contract includes a fixed price that is locked in until 31 July 2027, providing long-term stability and predictability for household budgets. A green electricity option is available for an additional two pounds per month, allowing customers to support renewable energy while benefiting from competitive pricing. The subscription fee of 16.4 pounds per month is modest, contributing to an overall cost structure that appeals to budget-conscious households. Primeo's pricing strategy is designed to attract customers who value affordability and simplicity, with transparent terms and no hidden charges. The company's 125 years of experience, rooted in its Swiss parent group, lends credibility and reassurance to customers seeking a stable and trustworthy energy partner.
Customer service and market position
Primeo has a customer rating of 4.14 out of 5, based on over 2,400 reviews, which reflects solid performance in customer satisfaction. The dispute rate of 19 per 100,000 contracts is lower than that of ENGIE, indicating effective complaint handling and a focus on maintaining positive customer relationships. Primeo's customer service is accessible through telephone and online channels, with support staff available to assist with account management, billing queries, and technical issues. The company's approach emphasises responsiveness and clarity, ensuring that customers feel supported throughout their contract period. While Primeo does not offer gas to individual customers, its electricity contracts provide a compelling alternative for households seeking competitive pricing and fixed-rate stability. The absence of a gas offering may limit its appeal to customers looking for a single supplier for both fuels, but for those focused on electricity, Primeo represents a strong choice that balances cost, service quality, and environmental responsibility.
