The best Octopus Energy tariff depends on your lifestyle and energy usage. For flexibility, the Flexible Octopus is a great starting point. If you want budget certainty, go with a Fixed tariff. For solar and battery homes, Octopus Flux or Intelligent Flux may offer the best returns.
Octopus Tracker updates your electricity rates daily based on wholesale market prices. You’ll see transparent, real-time pricing via the Octopus app. It can offer significant savings, but it also carries more price volatility — ideal for users who actively monitor their usage.
Yes — Octopus Energy allows customers to switch tariffs without exit fees in most cases. You can move between Flexible, Fixed, Tracker, Cosy, and other options as your needs change, often right within the app.
Some tariffs require a smart meter, especially:
These tariffs rely on half-hourly readings to optimise pricing. Octopus provides free smart meter installations for most eligible homes.
Octopus Flux requires manual control of your battery system to take advantage of peak/off-peak rates. Intelligent Flux, however, automates everything — but only works with GivEnergy battery systems. Both allow you to earn money by exporting solar energy during peak hours.
Octopus Energy generally does not charge exit fees, even on fixed tariffs — but this can vary based on market conditions. Always check the terms when switching to a new fixed deal.
Typically, new customers join Octopus on the Flexible or Fixed tariff first while Octopus checks if your smart meter is compatible. Once confirmed, you’ll be eligible to switch to Tracker, Cosy, or other smart tariffs.
