Octopus Flux

Octopus Flux is a three rate electricity tariff combining both import and export.

Octopus Flux is a combination tariff, meaning it's made up of an import and export tariff. The symmetrical import/export tariffs have three price periods throughout the day.

Yes, it is a flexible tariff. This means the unit rate and standing charges can rise and fall with wholesale energy prices.

When the rates of our flexible tariff changes, the price of Flux will also change. We'll always give reasonable notice of any changes to your prices, and there's no exit fees or tie-ins; you're free to switch tariffs or change suppliers at any time.

There's no exit fees or tie-ins, so if Octopus Flux doesn't work for you, you're free to switch tariffs or change suppliers with no penalties at any time.

You'll need to have:

• A smart meter providing us with half-hourly readings

• A solar system and home battery

• A copy of the MCS document or a FlexiOrb certificate for your solar system

• Confirmation your local energy network was notified of your installation*

*This will be a letter or email you got from your energy network, after they were notified by your solar installer.

Without half-hourly readings we can't create bills and payments for Flux.

If you don't have a smart meter, add your name to the list and we'll contact you as soon as we have an engineer available.

Yes, you can join Octopus Flux if you have an electric vehicle.

Firstly, there is no requirement to switch your FiT generation contract to Octopus.

Moving to Octopus Flux means:

Generation Tariff - your payments for energy generation will remain the same. You will not lose your generation tariff (and it should equate to the majority of your FiT income anyway).

Export Tariff - you will need to permanently opt-out of 'deemed export' payments. Instead, you'll receive the Octopus Flux export rate (which varies depending on your location) for every kWh actually exported, as measured by your smart meter.

If you receive FiT export payments from a supplier other than Octopus, we'll let you know when you need to contact them to cancel them. Once confirmed, we'll switch you to Octopus Flux.

If you leave Octopus Flux and / or Octopus Energy your 'Generation Tariff' will remain the same and your 'export tariff' will be paid at the Smart Export Guarantee (SEG) rate offered by your new tariff / new supplier.

There's no limit to the export rate set on our tariff, or on your smart meter, and the total electricity you export per month isn't limited.

However, your solar system won't be able to handle exporting energy beyond a certain point. Your solar panel installer will have ensured their maximum output will be within the limit of the breaker in your home (usually between 40 and 100 amps).

Number one and most important: no matter what your In-Home Display (IHD) - the little portable screen you get with smart meters - says, your super cheap period stays between 02:00 - 05:00 UK local time while your peak period stays between 16:00 - 19:00 UK local time all year round.

You should trust what we put on your bills. The IHD isn't really determining anything on your meter or tariff, rather just showing some information that might not be correct. Ultimately, our system is set up to account for changes due to daylight savings, so please don't worry: your bills and charges will be correct!

As an alternative, you can use the Octopus mobile app instead and be assured that you are seeing the correct information at all times.

Yes, with Octopus Flux you'll need to manually schedule your battery to charge and discharge based on Flux's unit rates. Generally, we'd recommend to charge your battery between 02:00 to 05:00 each night and to discharge between 16:00 to 19:00 when it'll be more expensive to import energy.
