1.
Low import rates, we'll make sure your battery charges when the price is lowest and the grid is greenest.
2.
A peak rate between 16:00 - 19:00, our optimum time to discharge your battery and export surplus energy back to the grid, don't worry we'll take care of this.

Intelligent Octopus Flux is a product of our labs, available now to customers through our beta programme
Intelligent Octopus Flux is a beta product. Some things may not work the first time, and installations and processes may take longer than we'd like. Third party tech like In-home Displays won't always work, and on occasion data issues with smart meters can take significant time to fix or prevent things from working at all.
Intelligent Octopus Flux is currently compatible with Enphase & GivEnergy batteries. Got a different battery? Tell us which one and we'll let you know when we can connect.
If you're cool with this, and you'd still like to work with us to make world-changing energy tariffs a reality, check this box so we know you're on board. You will always be able to switch to one of our fairly priced standard tariffs at any time.
