Good to know...
Intelligent Octopus Flux is reliant on the UK's smart meter network, which means there can occasionally be issues we don't have control over.
Some industry-standard tech (like In-Home Displays) might not work perfectly, and some processes like installations may take longer than we'd like.
This product is right at the cutting edge of energy tech, so very occasionally, some things might not work the first time.
Save £100 a year or more compared to a standard flux tariff
Intelligent Octopus Flux is a smart import and export tariff optimised to give you the best rates for consuming and selling your energy. Compared to our clever-but-not-quite-Intelligent Flux tariff, Intelligent customers could save £100 or more each year.



Import rates even lower than standard Flux, we’ll make sure your battery charges when the grid is the greenest.
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.
