Choosing the right Octopus Energy tariff depends on whether you prefer the price certainty of a fixed tariff, the flexibility of a variable tariff, or one of Octopus Energy’s smart tariffs.

Flexible Octopus is Octopus Energy’s standard variable tariff. Its unit rates and standing charges can change over time, while the tariff is protected by the Ofgem Energy Price Cap.

Fixed Octopus tariffs offer more price certainty because your unit rates and standing charges are fixed for the duration of the contract. However, the tariffs and rates available change regularly, so it’s worth checking the latest Octopus Energy tariffs before choosing.

Octopus Energy also offers a range of smart tariffs, designed for customers with compatible smart meters and particular energy-use patterns, including tariffs aimed at electric vehicle charging and shifting electricity use to different times of day.

Below, I’ll explain the main differences between Octopus Energy fixed and flexible tariffs, what to consider when choosing between them, and how to check the latest tariff available for your home.

Fixed vs Flexible Octopus: what’s the difference?

If you’re considering switching to Octopus Energy, one of the main decisions is whether you prefer a fixed or variable tariff.

With Flexible Octopus, your unit rates and standing charges can change over time. The tariff follows Ofgem’s Energy Price Cap, and you have the flexibility to move to another tariff if you find a more suitable option.

With an Octopus Energy fixed tariff, your unit rates and standing charges are fixed for an agreed period, which can make your energy costs more predictable. The fixed tariffs available can change, so always check the current tariff details, rates and any exit fees before choosing one.

Which is better: Flexible Octopus or a fixed tariff? There isn’t one option that’s best for everyone. A fixed tariff may appeal if you value price certainty, while Flexible Octopus may suit you if you value flexibility and don’t want to lock your energy rates in for a set period.

Octopus Energy’s tariff rates and offers change over time, so it’s worth comparing the latest Octopus Energy tariffs before making your decision.
