Where Octopus Flux wins

  • Homes that value explicit export windows and clearer daily charge-discharge structure.
  • Users looking for a more disciplined export-first battery strategy.
  • Properties where premium export periods are central to the economics.

Where Octopus Agile wins

  • Homes that can exploit large intraday swings and occasional plunge pricing.
  • Users who want broader automation upside from half-hourly volatility.
  • Battery homes able to adapt quickly around changing prices without depending on fixed windows.

What both tariffs can still get wrong

Neither tariff is automatically superior; both depend on the real household load shape.
Solar output, reserve protection, and evening demand can flip the decision.
The better answer often changes between summer export season and winter heating season.

Practical verdict

  • Choose Flux when export windows are important and the household prefers structured battery behaviour.
  • Choose Agile when the home has enough flexibility to benefit from broader half-hourly variation.
  • Before switching, verify whether your home earns more from explicit export windows or from flexible intraday battery control.
