- Octopus Tracker: Prices follow wholesale energy costs more closely, which can be useful when market rates are lower.
- Intelligent Octopus Go: Built for EV drivers, with cheaper overnight charging and smart scheduling through the Octopus app.

4. EV Charging Support
EV tariffs are useful for customers who charge their electric car at home and want cheaper overnight electricity instead of paying full daytime rates.
Octopus Energy: Intelligent Octopus Go offers 6 hours of cheaper overnight electricity, usually from 11:30pm to 5:30am, with an off-peak rate around 8p/kWh. It is stronger for EV drivers who want smart charging, app control, and a longer low-cost charging window.

5. Renewable and Low-Carbon Energy
Both suppliers focus on cleaner electricity, but their energy approach is different: Octopus leans more towards renewable electricity, while EDF is strongly linked with low-carbon nuclear power.
Octopus Energy: offers 100% renewable electricity and has built its reputation around green energy, clean tariffs, and modern low-carbon products. Its green positioning is stronger for customers who specifically want renewable-backed electricity and a supplier that actively promotes solar, batteries, heat pumps, EV charging, and smarter energy use.
EDF Energy: focuses on low-carbon electricity through a mix of nuclear and renewable generation. In 2025, EDF reported that around 95% of its electricity production was decarbonised, mainly from nuclear power and renewable sources. Its energy mix is less “renewable-only” than Octopus, but it has a strong low-carbon profile because nuclear power produces electricity with very low carbon emissions.
6. Customer Support Experience
Customer support should be judged from both independent ratings and real customer reviews, because one shows service performance and the other shows customer sentiment.
Octopus Energy: performs strongly in Citizens Advice data, with an overall score of 3.78/5 and a supplier rank of 3rd. It also scores well for contact waiting time and customer comments. On Trustpilot, Octopus has around 801K+ reviews with a 4.8 rating, showing strong customer satisfaction at scale.

7.Digital Account and Usage Tracking
Digital tools help customers manage bills, payments, meter readings, and energy usage without calling customer support.
Octopus Energy: app gives customers clear usage tracking through the Usage tab. Customers can view daily, weekly, monthly, yearly, or custom usage graphs in kWh and pounds. Smart meter users can also see more detailed usage data, including half-hourly readings where available. The app also supports account balance, bills, payments, and meter reading management.
EDF Energy: offers account management through My Account and the EDF app. Customers can check bills, payment history, account balance, tariff details, and submit meter readings. Smart meter users can also use Energy Hub to view energy use in kWh and cost, track changes over time, and get energy-saving tips.
8. Business Energy Suitability
Business energy needs can be different from home energy because companies often need fixed contracts, tailored rates, multi-site support, and clearer control over electricity and gas costs.
Octopus Energy: offers business electricity and gas tariffs for SMEs and larger companies, with options such as fixed-rate contracts, green energy plans, and smart tariffs like Shape Shifter, which uses half-hourly pricing. Its business rates can vary, but typical 2026 figures are around 24p–28p/kWh for electricity and 6p–9p/kWh for gas. Octopus also offers export tariffs for businesses with solar panels, including flat and agile export options.
EDF Energy: provides business electricity and gas tariffs for different company sizes, with a stronger focus on fixed-price contracts and budget certainty. It also offers options for specific needs, such as zero standing charge plans, small business electricity tariffs, and tailored business energy support. EDF may suit businesses that want a more traditional supplier with fixed contract options and reliable account management.
9. Supplier Stability and Market Position
