Intelligent Octopus Flux: Reviewed.

This is how the Intelligent Octopus Flux tariff works with your solar panels and battery storage.  Navigating solar export tariffs can seem daunting but I will run through how much you could earn from your solar electricty and if it’s the best Octopus tariff for your home.

I have been a happy Octopus Energy customer for 6 years and have solar panels and battery storage.

Review written by Sarah Chambers



Intelligent Octopus Flux explained.

Solar export tariffs aren’t new. Payments for solar electricty generated in UK homes started in 2010 and expanded in 2020. In 2024, most consumers know they can get paid for excess electricty generated on their roofs.  However, Octopus Energy has taken it a stage further with its Intelligent Octopus Flux tariff.

Intelligent Octopus Flux is a smart import and export tariff for homes in the UK with a GivEnergy battery and solar panels.

The Octopus “Intelligent” tariffs allow for home automation.  The Intelligent Octopus Flux tariff eliminates the hassle of exporting excess solar electricty from your home battery. Octopus takes care of it all.

Intelligent Flux is a next-generation solar export tariff that uses Octopus’  Kraken software to optimise your GivEnergy home battery and electricty solar generation. It’s not just designed for exporting the excess solar electricty. Intelligent Octopus Flux helps balance both your imported and exported electricty. It covers all the bases.

With a little Octo magic, your virtual home power station will help the stability of the National Grid, whilst also providing smarter, cheaper greener electricty for your home. 🌍

The element I like with the Octopus “Intelligent” tariffs is that Octopus configures your green hardware to get the best deal for your electricty. This is great if you don’t have the time or are less tech-savvy.

On Intelligent Octopus Flux Octopus will choose the best times for importing and exporting electricty to your home potentially avoiding short-term use of fossil fuels to fill the gaps.

We’ll export the energy you have stored when you’ll make the best return. So you’ll always get the best deal on the sunshine you have stored ☀️ – Octopus Energy.

Am I eligible for the Octopus Intelligent Flux tariff and more importantly do I need it?

To switch to Intelligent Octopus Flux you will need;

  • To be an Octopus Energy customer.
  • Have solar PV and a GivEnergy home battery.
  • A smart meter which provides Octopus with half-hourly readings.
  • A copy of the MCS document 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.

If you haven’t had your solar panels and battery storage installed yet you get a quote from Octopus Energy using this online form. (You’ll also see a lovely video of me on the Octopus website.)

If you receive feed-in tariff payments from Octopus or another supplier, they’ll also need a copy of your (Microgeneration Certificate Scheme) MCS certificate.

The Intelligent Octopus Flux tariff is a beta tariff, and at the moment you will need both solar panels and a GivEnergy battery to qualify for this tariff but hopefully, Octopus will add more batteries soon.  You can vote if you want your battery to be considered by Octopus.

How much will I pay for importing electricty and exporting solar electricity on the Intelligent Octopus Flux tariff?

Intelligent Octopus Flux covers both import and solar export. Unlike its sister tariff Octopus Flux, the intelligent versions of the Octopus Flux tariff not only decide when to sell your solar energy but also allow you to import electricity at a cheaper rate. So you work less for more with the Intelligent Octopus Flux tariff, which sounds like a very cunning plan indeed.

Intelligent Octopus Flux Electricty Import / Solar Export Rates.

From 1st of July 2024.

  • Off-peak (21 hours): 20.13 p/kWh (10% below the Flexible Octopus Tariff.)
  • Peak (4 pm – 7 pm):  26.84 p/kWh (Above Flexible Octopus for 3 hours.)

The Octopus Flexible Tariff is the Octopus default electricty tariff that is always 10% below the current Energy Price Cap. The rates changed on the 1st of July 2024.

For 21 hours of the day, you’ll pay 10% less than you would pay on the Octopus Flexible tariff. Intelligent Octopus Flux is the same price for both import and solar export.  I think Intelligent Octopus Flux has a very impressive solar export rate even before the boost between 4 pm and 7 pm! However, can you beat it if you decide to manually discharge yourself?

Intelligent Octopus Flux Tariff

Octopus Flux v Intelligent Octopus Flux.

  • On the Octopus Flux Tariff, you can have any home battery set up.
  • On the Octopus Flux Tariff, you have to monitor and control import and solar export times via your home battery set-up.
  • On the Intelligent Octopus Flux Tariff, you will need a GivEnergy battery.  (More batteries will be added to the list soon.)
  • On the Intelligent Octopus Flux Tariff Octopus optimises your electricty import and solar export times using their Kraken software. You just watch the magic happen on the Octopus App.

As a comparison between Octopus Flux v Intelligent Octopus Flux, you can see the current rates for the Octopus Flux Tariff and Intelligent Octopus Go below. (The quote is for South Wales)

If you have a GivEnergy battery and qualify for Octopus Intelligent Flux the solar export rates are better than on Octopus Flux. If you are going to be using Intelligent Octopus Flux as a seasonal tariff for the spring and summer months the electricty import rates are slightly irrelevant. Because if you produce enough solar energy to fill your battery for use after dark, which will be later in the day you won’t need to import hardly any electricty anyway the only figures that are important are the solar export rate.

 “Octopus Energy continues to unlock a grid system that is green, cheap and easy for customers. Next generation smart tariffs like Intelligent Octopus Flux optimise energy tech in people’s homes – passing on savings to customers while stopping the need for dirty fossil fuel plants at peak times.” – Alex Schoch, Octopus Energy.

Why do I need an MCS certificate to switch to Intelligent Octopus Flux?

The Microgeneration Certification Scheme (MCS) is a standards organisation. If you are looking for a comparison it’s similar to Corgi registered (for gas) but the MCS is for low-carbon technologies. Unlike Corgi where gas fitters have to be registered MCS is not a legal requirement. It is more a mark of quality for heat pumps, solar, biomass, wind and battery storage installation and Octopus has decided to make it a requirement in the terms and conditions.

If you are not sure if your system has an MCS certificate or you just can’t find it you can contact MCS at 0333 103 8130, or email: hello@mcscertified.com.  If you are looking for an installer you can also check if they are listed as MCS certified.

When Octopus receives your MCS certificate they will apply to the Distribution Network Operator (DNO) for an export Meter Point Administration Number (MPAN ) for your smart meter. Once the MPAN is registered by the DNO Octopus can then start paying you for your exported electricity.

Can I get paid for my solar export without an MCS Certificate?

Octopus Energy is launching a trial where no MCS Certificate is required for solar export but this is separate from this tariff where an MCS Certificate is still required.

I double-checked with Octopus on Twitter and here is their response from 5th August 2023.

How do I switch to the Intelligent Octopus Flux tariff?

You will need to switch to Octopus Energy first on their Octopus Flexible electricty tariff and once the switch is complete you can start the tariff switch to Intelligent Octopus Flux. If you use the linked page below to sign up you’ll get £50 credit after your first direct debit payment.  (I’ll also get £50 too so a big thank you if you use my link) As a new customer, you will need to switch to the Octopus Flexible tariff first before moving to any other Octopus tariff.

You’ll need to set up your solar export tariff with Octopus. I would suggest signing up for either Octopus Outgoing or Octopus Flux. Once your solar export is set up, you can request to switch to Intelligent Octopus Flux.

Octopus will send instructions once you have asked to switch tariffs.

How does the Octopus Intelligent Flux tariff compare to other solar export rates?

Octopus is very different from any other energy supplier in the UK. They offer such a wide range of electricty tariffs both traditional and smart that you do need to consider your energy use to find the best combination of electricity import and solar export tariffs for your circumstances. It can seem a little complicated to work out what’s right for you but hopefully, my blog will help.

You don’t need to have your home electricty supplied by Octopus to be on an Octopus solar export tariff but the Intelligent Octopus Flux tariff combines both electricty import and solar export. You can read about other combinations of SEG and Outgoing tariffs on my other solar export review page.

If you want to ask any questions there is a great community on Twitter and you can always tag me @sarah_go_green.Here is a list of some of the traditional expert tariffs and prices just to give you an idea. The minimum rate you would get for export is 20.13p per kWh on Intelligent Flux rising to 26.84p per kWh between 4 pm and 7 pm. (This may vary slightly based on your geographical location.)

An example of Solar Export rates.

  • Octopus Energy Outgoing tariff – 15p per kWh (Have an import tariff too)
  • Scottish Power – 15p per kWh  (Have an import tariff too)
  • Scottish Power – 12p per kWh
  • British Gas – 15p per kWh (Existing customer)
  • British Gas – 6.4p per kWh
  • EDF – 5.2p per kWh (Existing customer)

The solar export rates on Intelligent Octopus Flux are significantly higher as you can see.

Is Intelligent Octopus Flux a good all-year-round tariff for solar export?

The Intelligent Octopus Flux electricty import and solar export rates are very interesting especially if you want a hands-off approach to your home energy system but is Intelligent Octopus Flux for everyone?

You could consider having two tariffs, one for winter and one for the summer. It obviously depends on your home set-up and energy needs but I have written a recent blog about seasonal Octopus tariffs that you may find of interest.

In the winter for example when there are fewer hours of sunshine you may want to top up your battery overnight at a low off-peak electricty rate and then discharge energy from the battery to run your home. Intelligent Octopus Flux offers an off-peak rate of 10% below the Flexible tariff but Economy 7 is much cheaper at night, whilst Octopus Agile if electricty is in abundance will pay you for using and storing energy.  So switching tariffs later in the year may help to reduce your energy bills for the winter period. It just depends on the level of involvement you want to have.

GivEnergy All In One Battery.

If anyone considering buying a GivEnergy battery I have just had the GivEnerg All In One Battery installed by Octopus Energy along with solar panels. (You can read about my first steps towards an Octopus Energy solar and battery installation here.)  If you have solar panels installed already you could also add the GivEnergy battery if you contact a local installer. At the moment there is no VAT on a home battery. GivEnergy has a list of recommended installers on its website.

Having a home battery can help balance the grid making it cleaner and greener.

The chart below shows a day’s electricty use for a home with battery storage and solar panels. The battery is charged at night and discharged throughout the day. The battery works alongside the home’s solar panels to act like a virtual power station.

One of the main benefits of a home battery is being able to import electricty when there is less demand on the National Grid. Even in this example, without any pricing information, you can see that by topping up your battery at night this home has become self-sufficient during the day. This reduces peak demand at times when coal power stations might be forced to come online. For lots of people who are concerned about the environment, this will be a very attractive idea.

It is a win, win if you’re not very techie and want to save money and make a difference. Intelligent Octopus Flux will do all the hard work for you if you have solar panels and battery storage.

There are other Octopus Energy tariffs that could help reduce your energy bills if you have battery storage and solar panels. You must have a look at these tariffs too before making a decision that is right for you.

Should we allow an energy company to control household tech, such as home batteries?

I have added this question as I was contacted by someone who follows my blog today. They are having solar panels and battery storage installed soon but they don’t like the concept of allowing an energy firm to control household gadgets. They worry this will be a slippery slope where energy firms will dictate how and when we use energy. I on the contrary see this as an amazing step forward.

I get emails from lots of people who are buying green tech but worry that they aren’t making the most of it. They don’t fully understand if they have chosen the right tariff or indeed are making the most of the opportunities that Octopus smart tariffs provide. I let Octopus control EV charging at the moment. It’s a similar tariff to Intelligent Octopus Flux but they control my EV rather than a home battery. It is so easy and I know I am using my energy when it is the cheapest and greenest.

I think we need companies like Octopus to shake things up. They need to wake up the industry showing them what is possible whilst also guiding us on the journey. I think the Intelligent Octopus tariff will do that hand-holding very nicely as we all make our own personal attempts to help reduce our carbon footprint and save some money on the way.

Conclusion – How I have decided to maximise my solar export return.

I have a very busy household where I consume a lot of electricity. My 3 teenage daughters are home most of the day and I have an Electric Vehicle.

I haven’t chosen Intelligent Octopus Flux because I prefer the combination of Intelligent Octopus Go and Octopus Outgoing fixed for my solar export BUT every home and everyone’s energy needs are different.

The ratio of electricty import to solar export just isn’t enough to justify the switch to Intelligent Octopus Flux for me but that’s what makes Octopus smart tariffs so attractive, there are just so many options. As my family dynamics change, I can reconsider my tariff choices.
