Octopus Flux is an import and export tariff optimised to give you the best rates for consuming and selling your energy and support the grid during peak periods.

  1. Super cheap rates between 02:00 - 05:00 every day, when you can top up your battery with any extra energy you may need.
  2. A peak rate between 16:00 - 19:00, the optimum time to discharge your battery and export surplus energy back to the grid.

Here comes the sun

You need solar panels to be eligible for Octopus Flux, but they don't need to have been installed by us. If you're in the process of getting them installed, we can still start your switch.

Don't have solar yet but want an estimate? Check out our solar & battery page.

P.S. We'll need a copy of the MCS document for your installation before we can complete your switch.

To switch to Octopus Flux you'll need to:


Be an Octopus Energy customer

If you're not with us yet, register your interest below to join us on one of our standard tariffs initially while we connect all the dots behind the scenes.


Have a smart meter we can connect to
We can connect to second generation (SMETS2) meters, and some types of first generation (SMETS1) smart meters.


Hang tight while we connect to your smart meter

It generally takes us around 14 days to connect to a smart meter so we can read it remotely – whether it's one we've just installed, or one we're taking over after you switch to us. Read more on this.


Accept our Terms & Conditions via email

Once we're connected and getting half–hourly readings from your smart meter, we'll send you an email asking you to accept the Terms & Conditions of Octopus Flux to complete your switch. Have a read of our smart tariff Terms & Conditions now.


You're good to go!

Your tariff will change automatically to Octopus Flux. You should see the change straight away on your online account.

Octopus Flux is a product of our labs, available now to customers through our beta programme

You'll need a SMETS2 smart meter, or some types of first generation (SMETS1) smart meters, that we can receive half-hourly consumption data from.

Don't have a suitable smart meter?

Start your switch below to register your interest for a smart meter. The smart meter installation comes at no extra cost.

Once you've registered your interest, our team will be in contact when we have an appointment in your area.

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.

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.

Octopus Flux is a cutting edge innovation created by Octopus's unique technology. Unlike products available from other companies, it relies on a smart meter system (which as our Founder Greg explains here, is not always fully reliable). Some customers have experienced delays. However, of the thousands of customers on these smart tariffs, the vast majority are now experiencing smooth service.

Octo 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.

Octopus Flux rates are changing from 1 July 2024. You can see the rates by region here.

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.
