1. At a Glance
• Intelligent Octopus Flux is a smart, variable time‑of‑use tariff that pays you and charges you different rates depending on the time of day.
• The average UK household can pocket £763 a year just from exporting through Intelligent Octopus Flux, on top of the bill savings you get from using your solar power.
• You need solar panels, a compatible battery, and a smart meter. Octopus's clever software then automatically buys low, sells high and squeezes every penny of value from your battery.
• Import and export rates move with Ofgem's quarterly price cap, but Flux has stayed near the top of the market since its launch.
• No exit fees, and you're free to stay on your existing Octopus import tariff or switch if something better comes along.

How the Flux Tariff Talks to Your Solar, Battery & Smart Meter
1. Forecast - Each night, Intelligent Octopus Flux looks at tomorrow's weather and wholesale costs.
2. Plan - The platform decides how much cheap, off-peak grid electricity to pull into your battery before dawn.
3. Store - Your battery tops up when import rates dip roughly 10 % below the Octopus standard variable.
4. Flux - Between 4 pm and 7 pm, the software empties the battery to your house and the grid, earning the higher peak export rate.
5. Balance - If clouds roll in or you use more power than expected, the algorithm recalculates in real time.
Key takeaway: You earn top-tier export rates and avoid peak import prices without lifting a finger.
Why a Smart Meter Export Reading Matters
Flux hinges on half-hourly data. Your smart meter sends Octopus granular import and export figures, so you get paid precisely what you deserve.
Real‑World Savings and Earnings
Below is a typical scenario using average UK figures (3,400 kWh household demand, 4.4 kWp solar array, 5.2 kWh battery, 850 kWh/kWp irradiance, 65 % export share):
• Annual grid imports avoided: ~1,190 kWh
• Bill saving (at 29 p/kWh peak, 21 p/kWh off‑peak): ≈ £264
• Annual exports on Intelligent Octopus Flux: ~2,430 kWh
• Export income (weighted average 25 p/kWh): ≈ £608
• Battery arbitrage uplift (charging cheap, selling high): ≈ £155
Total benefit: ~£1,027 per year
Even a modest 3 kWp system with a 5 kWh battery still clears £600+ in combined profit and savings thanks to Intelligent Octopus Flux.
(Figures are illustrative; your mileage will vary with roof size, region and consumption.)
Notice: Intelligent Octopus Flux keeps the import and export figures level within each band. That single difference vs ordinary export tariffs creates a fair, transparent marketplace for domestic solar.
Eligibility Checklist & Easy Sign‑Up Steps
You'll need
• An Octopus Energy import account (any variable or fixed deal).
• Solar panels registered under MCS or Flexi‑Orb.
• A compatible battery (most major brands supported - we'll advise).
• A smart meter capable of half-hourly export reads.
• An Android or iOS device to run the Octopus app.
Sign‑Up in Five Simple Moves
1. Switch import supply to Octopus (if you haven't already).
2. Apply for an export MPAN via Octopus (they handle DNO paperwork).
3. Install your battery - our engineers commission it with smart‑control firmware.
4. Send Octopus your first smart‑meter export read once MPAN is live.
5. Open the Octopus app and enrol on Intelligent Octopus Flux.
Typical timeline: 5-11 weeks from the first switch step to your first day on Flux.
Flux vs Other Time‑of‑Use & Export Tariffs
Bottom line: If you own a compatible battery, Intelligent Octopus Flux consistently pays more and saves more than any rival export tariff in the UK today.

8. Frequently Asked Questions
Q. Will Intelligent Octopus Flux wear out my battery faster?
A. No. Modern lithium-ion batteries are rated for thousands of cycles. Octopus keeps the depth‑of‑discharge moderate to preserve warranty life.
Q. Can I run multiple batteries?
A. Yes, Flux recognises parallel inverters. Just be sure every unit is on Octopus's approved list.
Q. Is this tariff fixed or variable?
A. It's variable and resets every quarter in line with the Ofgem price cap, but Octopus publishes rates weeks in advance.
Q. What if I also own an EV charger?
A. You can stack Intelligent Octopus Flux with Intelligent Octopus Go for EV charging, but you'll need a second smart port on your meter. Talk to us - we install both.
Q. Do I have to programme anything?
A. Apart from naming your battery in the app, Octopus automates everything. Set‑and‑forget simplicity is the beauty of Intelligent Octopus Flux.
Is Intelligent Octopus Flux Right for Your Home?
Perfect matches
• Households with 4 kWp+ solar and a 5 kWh+ battery.
• Families out during the day who use most electricity after 4 pm.
• Tech-savvy homeowners who like real-time app data.
Situations to check carefully
• Off-grid properties (smart meter signal needed).
• Homes with micro‑batteries (< 2 kWh) - gains may not outweigh standing charges.
• Customers are already locked into multi-year fixed import tariffs above 50 p/kWh.
If you're unsure, our energy consultants can run a personalised flux‑versus‑fixed simulation using your actual usage data.
The Future of Smart‑Meter Export Tariffs
Industry analysts expect UK domestic demand for battery storage to triple by 2030. As electric‑vehicle charging and heat‑pump adoption rise, flexible time‑of‑use tariffs like Intelligent Octopus Flux will become the norm.
• Octopus doubled its Outgoing Fixed rate in 2022 and launched Flux in 2023.
• E.ON, Good Energy, British Gas, EDF and OVO have all hiked their export deals in response.
• National Grid ESO predicts that broad household storage could cut curtailment costs (paying wind farms to switch off) by £2 billion a year by the late 2020s.
Translation: Early adopters benefit most. The sooner you enrol on Intelligent Octopus Flux, the longer you lock in generous arbitrage spreads before mass uptake erodes peak‑hour premiums.
