Engie particuliers
ENGIE stands as a formidable presence in the energy market, combining decades of expertise as a longstanding natural gas supplier in France with a forward-thinking approach to renewable energy. The company has positioned itself as a reliable choice for households seeking both stability and environmental responsibility. With customer service available seven days a week, ENGIE demonstrates a commitment to accessibility that sets it apart from many competitors. This dedication to service excellence was formally recognised when the company was voted Customer Service of the Year 2026 in the residential energy supplier category, an accolade that reflects the tangible improvements customers experience when dealing with the provider.
Comprehensive energy offerings and fixed price stability
One of the defining characteristics of ENGIE's approach to the market lies in its commitment to fixed electricity price and fixed gas price tariffs, providing households with predictability in an otherwise volatile energy landscape. This pricing structure shields consumers from sudden market fluctuations, allowing for more accurate household budgeting. Beyond pricing stability, ENGIE has established itself as the leading green electricity supplier in the market. Remarkably, all electricity offers are green at ENGIE, meaning that households automatically contribute to renewable energy adoption simply by choosing the provider. This wholesale commitment to renewable sources distinguishes ENGIE from competitors who may offer green tariffs as optional upgrades or premium services.
Natural gas leadership and enhanced green options
ENGIE's heritage as a longstanding natural gas supplier in France provides it with unparalleled expertise in this sector. The company has not rested on its historical laurels but has instead innovated by incorporating 5% green gas included in gas offers, demonstrating a pathway toward decarbonising even traditional fuel sources. For customers seeking to maximise their environmental impact, ENGIE provides Green Gas+ and Green Electricity+ options for 100% French green gas or green electricity, allowing households to source their energy entirely from domestic renewable installations. This tiered approach to sustainability enables customers to align their energy consumption with their environmental values whilst maintaining flexibility in their choices. The company's ambition extends beyond current offerings, as ENGIE aims to be carbon neutral by 2045, a commitment that provides long-term assurance to environmentally conscious consumers. With 5 million green electricity customers already trusting ENGIE for their power needs, the company has demonstrated its capacity to deliver renewable energy at scale whilst maintaining service quality.
Edf
EDF occupies a distinctive position in the energy landscape as the historical electricity provider, with roots stretching back to 1946. The company generates approximately 70% of France's electricity through nuclear power, representing a different approach to low-carbon energy compared to renewable-focused suppliers. Since becoming fully state-owned in 2023, EDF has maintained its role as a cornerstone of the national energy infrastructure. The company continues to offer the regulated electricity tariff known as Tarif Bleu, which is set by government authorities and provides a baseline against which market offerings can be measured.
Tariff structure and customer perception
EDF's market presence extends beyond its regulated tariff offerings to include various market-based electricity and gas plans designed to cater to different household needs. The company maintains an extensive customer service network, reflecting its long-established presence in the market. Customer ratings present a mixed picture, with scores of 3.2 out of 5 on Hello Watt based on nearly four thousand reviews, whilst Trustpilot users awarded a more generous 4.6 out of 5 from over forty thousand reviews. For a typical 100 square metre home, annual electricity costs approximate £3,404, whilst gas costs reach around £2,206. The Tariff Bleu regulated electricity pricing sits at 20.65 cents per kilowatt hour, with the Avantage Gaz tariff at 10.89 cents per kilowatt hour.
Environmental considerations and service range
Whilst EDF offers both traditional and renewable electricity options, the company has faced criticism from environmental organisations such as Greenpeace for not moving quickly enough toward renewable sources. The company's reliance on nuclear power, whilst low-carbon, does not align with the preferences of all environmentally conscious consumers. EDF's professional offerings include the Tarif Bleu for smaller businesses, Digiwatt as an online-only option, Vert Electrique for those specifically seeking green electricity, and various gas offers. The company typically proves more competitive on base electricity tariffs and peak-off-peak hour structures, reflecting its deep expertise in the electricity generation sector. For businesses and households prioritising tariff stability and service reliability backed by decades of operational experience, EDF remains a relevant consideration despite facing increased competition from more agile market entrants.
Totalenergies
TotalEnergies, formerly known as Total Direct Energie and before that Total Spring, represents the energy market expansion of a company traditionally associated with petroleum products. Since the market liberalisation in 2007, the company has accumulated approximately 2.5 million customers, demonstrating substantial market penetration. The supplier focuses on renewable energy offerings whilst maintaining competitive pricing that typically sits 5% to 10% below the regulated tariffs established by EDF. The company provides both electricity and gas services, with an emphasis on digital convenience through mobile applications and digital billing systems.
Pricing strategy and customer recognition
TotalEnergies positions itself as a value-oriented provider with pricing structures designed to undercut established suppliers. The online offer historically provided a 10% reduction compared to regulated tariffs, whilst green energy offers delivered savings of approximately 2% compared to EDF's baseline. For electricity, TotalEnergies tariffs approximate £0.14 per kilowatt hour, noticeably below EDF's regulated rate of approximately £0.16 per kilowatt hour. Gas tariffs similarly offer competitive pricing at around £0.07 per kilowatt hour. The company received recognition for its customer service approach, winning the Service Client of the Year award in 2018 for the ninth consecutive time, alongside receiving first prize in the Podium de la Relation Client 2018. Customer service remains accessible through a dedicated line operating Monday to Sunday from 9am to 7pm, reflecting a commitment to availability that extends beyond traditional working hours.
Business services and market positioning
For business customers, TotalEnergies emphasises flexibility and customer service quality. The supplier earned the Service Client of the Year award in 2024 specifically for business energy, recognising its effectiveness in serving commercial clients. Customer feedback highlights easy digital sign-up processes, though some criticism has been directed toward adjustment bills that occasionally exceed expectations. The company offers green electricity through guarantees of origin, though it lacks a standard biomethane offering for gas customers seeking the greenest possible option. In professional rankings, TotalEnergies scored 7.6 out of 10 in the 2025 energy supplier barometer, positioning it in the middle tier of business energy providers. The company caters to diverse business sizes from small enterprises to larger accounts, though its offerings may lack some of the technical depth that more established suppliers provide to industrial customers.
Enercoop
Enercoop represents a distinctive approach to energy supply, operating as a cooperative established in 2005 with a mission centred entirely on renewable electricity. The supplier serves approximately 112,000 residential and business customers, supported by 64,200 members who participate in the cooperative's governance. The company's electricity mix comprises 70% wind energy, 16% photovoltaic solar, 14% hydraulic power, and 0.2% biomass, creating a portfolio that exclusively draws from renewable sources. With annual revenue reaching £227 million in 2023, Enercoop demonstrates that environmental commitment can coexist with commercial viability.
Premium pricing for ethical energy
Enercoop's commitment to 100% renewable energy and cooperative governance structures comes with a pricing premium that reflects its ethical positioning. The Basic Watt offering charges 25.31 cents per kilowatt hour with an annual subscription of £177.84, resulting in an estimated annual budget of £1,621 for typical household consumption. This represents approximately 25.52% above the regulated tariff in base option, making it one of the more expensive choices in the market. The Flexi Watt option for households with peak-off-peak metering charges 27.46 cents during peak hours and 18.95 cents during off-peak periods, with a slightly higher monthly subscription. Customer satisfaction scores are notably strong at 4.79 out of 5, suggesting that those who choose Enercoop find value in its ethical approach despite the higher costs.
Transparency and dispute resolution
One area where Enercoop demonstrates excellence is in customer relations and dispute resolution. The supplier recorded only 6 complaints per 100,000 contracts with the National Energy Mediator, ranking first among 17 suppliers measured. This exceptional performance indicates that customer concerns are addressed effectively before escalating to formal dispute resolution mechanisms. Enercoop's electricity carries the VertVolt label with the highest designation of very engaged, certifying that the renewable credentials meet stringent standards. However, the supplier does not currently offer natural gas services for residential customers, limiting its appeal to households seeking a single supplier for both energy needs. For consumers prioritising environmental impact and willing to pay a premium for genuinely green electricity backed by transparent cooperative structures, Enercoop offers a compelling proposition despite its higher pricing.
Primeo
Primeo Energie entered the market as part of a Swiss group with heritage dating back to 1897, bringing continental European expertise to the competitive landscape. The supplier particularly targets small and medium-sized enterprises with competitive pricing structures, though it also serves residential customers. Operating 232 renewable energy sites across Europe, Primeo generated 1,489 gigawatt hours of green electricity in 2024, demonstrating substantial renewable capacity. The company maintains a respectable Trustpilot rating of 4.3 out of 5, suggesting generally positive customer experiences.
Competitive pricing and contract terms
Primeo's Fixe Eco offering provides a 15% discount on the kilowatt hour price compared to regulated tariffs, valid until July 31st, 2027. For typical household consumption of 6,000 kilowatt hours annually, this results in annual costs of approximately £1,219, representing savings of roughly 11.3% compared to some competitors. The monthly cost approximates £100.08, making it one of the more affordable options available. However, customers seeking green electricity may face an additional charge of around £2 per month. Customer ratings average 4.14 out of 5 across multiple platforms, slightly below the highest-rated suppliers but still indicating satisfactory performance. The supplier recorded 19 disputes per 100,000 contracts with the National Energy Mediator, a figure that compares favourably to many established providers.
Service limitations and market focus
A significant limitation for Primeo lies in its lack of natural gas offerings, restricting its appeal to households seeking comprehensive energy solutions from a single provider. The supplier offers contract durations of one to four years for businesses, with fixed pricing providing budget certainty over these periods. Customer service for individuals operates Monday to Friday from 9am to 5pm, a more limited schedule than some competitors offer. For businesses, particularly those in the medium consumption range of 36 to 250 kilovolt amperes, Primeo offers fixed-price deals that can deliver meaningful savings. However, larger enterprises consuming over 250 kilovolt amperes require custom quotations, and the supplier may lack some of the technical support infrastructure that more established providers maintain. Early exit fees are a consideration for customers who may need to switch suppliers before contract expiration, though the specific terms vary by contract type. Whilst Primeo offers competitive pricing and renewable options, its more limited service hours and absence of gas offerings may steer households toward more comprehensive providers.
