Intelligent Octopus Flux review (November 2026)
Flux with Octopus deciding when the battery charges and discharges.
Not currently available to switch to
Octopus says the tariff is temporarily unavailable and directs readers to standard Flux.

Who Intelligent Octopus Flux is most likely to work for
Intelligent Flux hands battery scheduling to Octopus, which decides when to charge and discharge within the product's import and export structure. The supplier currently marks it temporarily unavailable, so this review must not be read as a switch offer.
In its favour
- Battery scheduled against actual wholesale prices
- Supplier-managed battery scheduling when the product is available
- Nothing to manage day to day
- No exit fees
Against it
- Only a limited set of battery systems qualify
- Octopus controls when the battery charges and discharges
- Requires solar and an export arrangement
- Needs a smart meter on half-hourly readings
Read the fuller verdict and trade-offs
It only applies to a short list of battery systems, and you are giving up day-to-day control of an expensive asset. If your battery is not on the list, or you would rather run it yourself, Flux is the same idea under your own hand.
- You hand over control of an expensive piece of equipment. If you have strong views about how your battery should be charged and discharged, this is not the tariff for you.
- Compatibility is narrower than for Intelligent Go, since it depends on the battery system rather than a vehicle.
- Joining replaces any existing deemed Feed-in Tariff export payment; you must tell a different FiT supplier when its export payment has been replaced.
- Check the battery manufacturer's warranty and operating conditions before handing control to a third party. Octopus says its charging plan should not affect battery life more than regular charging, but the manufacturer’s terms still govern your equipment.

Household fit
Who Intelligent Octopus Flux might be good for
The right answer depends on your equipment, routine and tolerance for changing prices—not just how much electricity you use.
Likely to suit
- Solar and battery homes with compatible hardware willing to hand over scheduling
- People who want the Flux economics without managing them daily
- Households whose battery is large enough to make the arbitrage worthwhile
Less likely to suit
- Owners of battery systems Octopus cannot control
- Anyone who wants to keep manual control of their battery
- Homes concerned about additional battery cycling
Before switching
Check the requirements and what will affect the result
What you need
- A compatible battery system that Octopus can control — the deciding factor, and worth confirming before switching
- Solar panels and a home battery installed and operational at the property Octopus supplies
- Working smart meters for both import and export, with both tariffs already supplied by Octopus
- A supported iPhone or Android device running the Octopus app so the battery can be connected
- G98 or G99, MCS and any Feed-in Tariff evidence available if Octopus requests it
What drives what you pay
- How well the scheduling performs, which is largely out of your hands
- Battery capacity and how quickly it can charge and discharge
- Generation over the year, which varies enormously between seasons
- Household consumption during the peak import band
How it works
How Intelligent Octopus Flux sets its prices
Octopus takes control of when the battery charges from the grid and when it discharges, aiming to buy when import is cheap and sell when export pays most.
Read the full pricing explanation
It factors in forecast solar generation, so on a sunny day it can leave room for your own production rather than filling the battery from the grid overnight.
When the tariff is offered, household usage is billed on its underlying band schedule; the automation applies to the battery, not to the rest of the house.
Match the tariff to your home
Your largest electrical loads can change the answer
A specialist tariff can be better aligned with one large device, but its eligibility and expensive periods still matter. These are comparisons to make, not automatic recommendations.
If you have solar without a battery
The import tariff and the rate paid for exported electricity are separate decisions. A straightforward export tariff can be more useful than a peak-weighted battery tariff when generation is exported as it happens.
If you have solar and a home battery
Intelligent Octopus Flux already targets a home with storage. Compare who controls the battery, the import/export bands and device compatibility rather than looking at one headline rate.

Other smart tariffs from Octopus and EDF to compare
These are other smart-tariff comparisons from the two suppliers, not a claim that every option suits the same household.
Octopus Flux
The same broad battery-shifting idea, but a different managed product.
More detail
Flux leaves the schedule to you; Intelligent Flux leaves it to Octopus. Compare the actual import and export terms as well as control and compatibility.
Intelligent Octopus Go
Different assets: Intelligent Go schedules a car, Intelligent Flux schedules a battery.
More detail
If you have both, you will have to decide which is worth optimising, since you cannot be on both tariffs.
Agile with Outgoing
More upside in theory and far more work in practice.
More detail
Intelligent Flux is the automated middle path for a solar and battery home that does not want to trade energy daily.
How to switch
Moving to Intelligent Octopus Flux
- 1
Confirm your battery system is one Octopus can control — this is the deciding factor and worth checking before anything else.
- 2
Solar with an export arrangement and a smart meter on half-hourly readings are both required. Import and export move together as a pair.
- 3
Existing customers switch from the dashboard; new customers join Flexible Octopus first. No exit fees.
Frequently asked questions
Which batteries work with Intelligent Octopus Flux?
It depends on Octopus being able to control your specific battery system, and the supported list changes. Confirm your model before switching, because without control the tariff loses its point.
Can I override the schedule?
The degree of control varies by setup. If retaining manual control matters to you, standard Flux keeps the schedule in your hands while offering the same rate structure.
Does it account for my solar generation?
Yes. The scheduling uses forecast generation, so it can avoid filling the battery from the grid overnight when a sunny day is expected.
Will more cycling wear out my battery?
More cycles do consume warranty life. Whether the extra revenue justifies that depends on your battery’s warranty terms and expected lifetime, and it is worth checking those before switching.
