Octopus Energy Tariffs in Scotland (2026): A Plain-English Guide for Solar, Battery and EV Homes

After spending thousands on solar panels, a home battery or an EV charger, sticking with your old tariff without comparing the alternatives is madness. A tariff that suits your kit and the way you use electricity can help it earn more.

JME Green Energy has an Octopus Energy referral (affiliate) link, and Octopus pays us when someone switches through it. We're still happy to answer “Which Octopus tariff should we go for?” honestly. The answer depends on the system you have installed and how your home uses electricity.

This guide compares Flux, Go and Intelligent Go, explains who can use them, and shows the costs and conditions to check before switching.

In short

• Today's South Scotland prices are in the live table further down, straight from Octopus and refreshed every hour. Want just the numbers? Bookmark today's Octopus Flux rates. Perth, Dunblane and areas further north are in Octopus's North Scotland region, which has its own rates.
• If you’ve got solar, a battery and an EV you don't drive much, look at Octopus Flux. Charging at night is cheap, you avoid the peak rate by running off your battery from 4pm to 7pm, and peak export pays well in summer. Intelligent Flux, where Octopus runs the battery for you, was marked "temporarily unavailable" on Octopus's page when we checked on 6 October 2026.
• If you’ve got a battery but no solar, Flux isn't open to you: Octopus requires solar panels and a battery. Look at a time-of-use tariff you do qualify for, such as Agile, Economy 7, Cosy (if you have a heat pump) or Go (if you charge an EV at home).
• Heavy EV miles, with or without solar: Octopus Go or Intelligent Go. A longer cheap window means a fuller EV charge overnight.
• Solar but no battery: Go if you've got an EV, plus Outgoing Octopus or Agile Outgoing for export. Flux needs a battery as well as solar. Not every import tariff can be paired with every export tariff, so check Octopus's current compatibility guidance before you switch.
• Variable rates can change at any time. Always check your Octopus app before switching.

Why the tariff matters as much as the kit

With solar, a battery earns by storing surplus you'd otherwise export. Without solar, it can only earn from the gap between cheap and peak electricity prices. On a flat-rate tariff every unit costs the same, so charging a battery with no solar at a different time can't produce any saving from a cheaper unit rate.

That gap is what time-of-use tariffs sell you. On Octopus Flux in South Scotland on 6 October 2026, a unit bought between 02:00 and 05:00 cost 14.27p and a unit imported between 16:00 and 19:00 cost 33.28p. Batteries lose some energy going in and out, so the real swing is smaller than the difference between those two prices, and it only applies to the units your home actually uses in that three-hour window. The breakdown is further down.

Get the tariff wrong and the kit can't earn what it should.

Flux, Go and Intelligent Go: the three Octopus tariffs to compare first

There are loads of Octopus tariffs floating around. For solar, battery and EV homes, these three are the ones to compare first. Agile, Economy 7 and Cosy suit some homes too, and the questions further down cover when.

Octopus Flux is the one designed for homes with PV and a battery. Cheap import overnight, expensive peak teatime, and a matching export tariff that pays the most when the grid's stressed. If you can shift your battery in and out at the right times, this is where the money is.

Octopus Go is the import-side EV tariff. Five hours of cheap power overnight, flat rate the rest of the day. Pair it with a separate export tariff like Outgoing Octopus, a flat 12p since March 2026 (still 12p when we checked on 6 October 2026), or Agile Outgoing if you fancy chasing the wholesale price. Go needs an electric car that you charge at home. Octopus only allows certain import and export tariffs together, so check its compatibility guidance.

Intelligent Octopus Go is the same idea but smarter. It works with a compatible EV or charger: your whole home gets six off-peak hours from 23:30 to 05:30, and Octopus schedules up to six hours of cheap car charging, inside or outside that window. Not every car or charger plays nicely with it, so check before you commit. Our EV charger comparison covers which units support it.

The Intelligent Flux version exists too. Octopus controls a compatible battery for you, but the rates aren't the same as Flux: on 6 October 2026 its South Scotland import rate was 26.22p from 16:00 to 19:00 and 19.67p the rest of the day, with no cheap overnight band. It also needs solar panels and a compatible battery, and Octopus's page said it was temporarily unavailable when we checked.

What does Octopus Flux actually pay in Scotland right now?

Octopus prices Scotland in two regions, and the boundary runs through our patch. Octopus's postcode lookup puts Stirling, Falkirk, Alloa, Linlithgow, Livingston and Dunfermline in South Scotland, but Dunblane, Callander, Perth and Dundee in North Scotland, which has a different rate sheet. Check your postcode with Octopus to confirm which regional rates apply.

Here are the live South Scotland rates, pulled straight from Octopus Energy and refreshed every hour. Octopus can change these variable rates at any time. North Scotland's are a little different: on 6 October 2026 its Flux import was 14.63p, 24.37p and 34.12p, and its peak export 28.73p.

For a permanent live-rates page you can bookmark, see today's Octopus tariff prices in South Scotland.

The peak export rate is what makes Flux different. Between 16:00 and 19:00, South Scotland Flux export paid 27.19p on 6 October 2026, nearly three times Flux's 9.55p daytime export rate. That suits homes with solar surplus or a battery still holding charge at teatime.

Here's what each kWh delivered by the battery is worth, per kWh rather than per year:

Using your own stored power at peak beats selling it. Each unit you don't import between 16:00 and 19:00 saves 33.28p, while each unit you export then earns 27.19p, so a unit used at home is worth about 6p more than one exported. That's why the battery should power your property first and only sell back the surplus.

We haven't put a yearly saving on this. It depends on how much your home uses at peak, how often solar has already filled the battery, and your battery's size and losses. For worked yearly examples, with every assumption shown, see our 0% VAT battery guide.

Answers to your questions on which tariff is best suited to your house

Most articles on this stop at “it depends”. Here are more specific answers.

Q. I've got solar, a battery, and I drive a normal amount. Which tariff?

Flux is built for this. The battery can be charged cheaply overnight in winter, and in the brighter months you can rely more on solar and earn the peak export rate when there's surplus. If the car does a lot of miles, compare Go or Intelligent Go too: their cheap windows are longer than Flux's three hours.

Q. I've got a battery but no solar yet. What should I be on?

Not Flux: Octopus requires solar panels as well as a battery. Your options are the time-of-use tariffs you qualify for:

• Agile follows the wholesale price every half hour and needs a smart meter Octopus can read. Between 1 January and 5 October 2026, South Scotland Agile averaged 18.5p from 02:00 to 05:00 and 37.8p from 16:00 to 19:00, by our count from Octopus's published prices. It went below zero for 220 hours in that time, but only 37 of those hours were between midnight and 7am. Most fell between 10am and 5pm. Agile is capped at 100p a unit, and individual days vary a lot from the average.
• Economy 7 gives a fixed cheaper night rate. Our worked example of a 5 kWh battery on Economy 7 in a typical 2,500 kWh home comes to about £150 a year off unit costs, which would take decades to repay a £5,000 battery. See the sums.
• Cosy Octopus if you have a heat pump or other electric heating, or Go if you charge an EV at home.

Selling grid-charged battery power back is less clear-cut. Octopus's Outgoing FAQ says you don't have to generate electricity to benefit, but its sign-up asks for an MCS certificate and the network operator's paperwork, which homes without solar won't usually have. Check with Octopus before counting on export income. Our battery-without-solar guide goes through the rest.

Q. I've got solar but no battery. What now?

Octopus Go if you've got an EV, paired with an export tariff like Outgoing Octopus or Agile Outgoing, where Octopus's compatibility guidance allows it. Flux isn't an option without a battery, and its higher peak rate would hurt you more than the cheap overnight rate helps.

Adding a battery is worth pricing up, but don't assume it pays for itself. A battery on existing solar earns the import price on the stored surplus but gives up that surplus's export payment. Our 0% VAT battery guide works through an example, and our battery storage installation page covers adding one to existing solar.

Q. I'm doing 200+ miles a week in an EV. Flux or Go?

Go or Intelligent Go. Five or six hours of cheap charging every night beats a three-hour Flux window when you're putting serious miles on a car. A 60 kWh EV needs roughly 8 hours on a 7 kW charger to fill from empty. The longer the cheap window, the more of that fits inside it.

Q. How do V2G and the Octopus Power Pack work?

Octopus Power Pack is Octopus's V2G (Vehicle-to-Grid) tariff. Octopus schedules your car to charge and to export back to the grid when it's needed, and in return your car charging is free, as long as you meet the tariff's conditions. We've covered V2G in full in our Scotland guide.

It's narrow for now. When we checked on 6 October 2026, the only compatible combination Octopus listed was a V2G-enabled BYD Dolphin with a V2G-enabled Zaptec Pro charger. You also need a compatible smart electricity meter and network operator permission to export (a G99 approval). To take part, you have to plug in for 12 hours a day, 20 days a month, and charge less than 210 kWh a month. That 210 kWh limit is a condition of joining, not a free allowance, and Octopus says regularly missing its targets means leaving Power Pack. Power Pack is added to a normal import tariff, but it can't be combined with Agile import, Agile Outgoing export, Tracker or any Intelligent tariff.

Getting your kit set up properly matters as much as picking the tariff

On Flux you set the battery schedule yourself. Octopus suggests charging between 02:00 and 05:00 and discharging between 16:00 and 19:00. In the darker months, charge in that overnight window. In the brighter months, cut back or switch off overnight charging so the battery has room for the next day's solar instead of you paying to fill it. Some battery apps can adjust for the weather forecast.

During the 4–7pm peak, the battery should power your property first, and only let surplus go to export after the house has used what it needs.

Use your EV charger's app scheduler (on a Zappi, Hypervolt or Ohme, for example) to lock charging into the cheap overnight window. If you have solar installed, a Zappi in Eco+ mode will divert genuine solar surplus to your car, provided its CT clamp is positioned and set up correctly. If the clamp is in the wrong place or isn't configured properly, the charger can misread the power flows and import electricity from the grid instead of using the solar surplus you intended.

Then there are export limits. Solar panels and batteries have to be registered with your local network operator. Government guidance says the installer works out from the equipment and the connection whether it's "connect and notify" (install, then send a G98 notification within 28 days) or "apply to connect" (a G99 application, or G100 where export is limited, approved before anything is installed). That matters on Flux, because exporting hard at peak is the point. Your inverter's export setting has to match what the network operator has approved, not what the battery could push out. As the owner, you're responsible for checking that the notification or approval is in place.

What about other suppliers?

Octopus pays us a referral fee when people switch through our link, so take this with that in mind: we think Octopus does this best at the moment. But you've got options. Other suppliers sell EV tariffs with cheap overnight windows, and Ofgem's Smart Export Guarantee requires some suppliers to offer an export rate. Compare their current terms and what they require before you switch.

If you're not currently with Octopus and you'd like to switch, our referral link gets you £50 of credit, subject to Octopus's eligibility conditions. Those say you must sign up online through the link, the credit is added after your first successful Direct Debit payment once Octopus is supplying you, and recent Octopus customers, or anyone who has already had a switching or referral credit, may not qualify. We also receive a referral payment from Octopus. We'd never push you to switch if your current setup is working. A battery on a flat-rate tariff can store solar surplus, but moving its grid charging to a different time doesn't reduce the unit price.

VAT, grants and what to check before you buy

Installed energy-saving materials carry 0% VAT until 31 March 2027. HMRC's VAT Notice 708/6 includes solar panels, batteries (including standalone batteries with no solar), heat pumps and smart diverters. It covers installation in homes; buying a battery without installation is charged at the standard rate. From 1 April 2027, HMRC says these installations go to the reduced rate of 5%, not back to 20%. On a battery priced at £6,000 before VAT, that's £6,000 now, £6,300 at 5% from April 2027, or £7,200 at the standard rate. Our 0% VAT battery guide has the detail.

Home Energy Scotland funding has shifted. The HES Grant and Loan funds clean heating, such as heat pumps, and insulation. Solar panels and batteries were removed from it in June 2024, even when installed with a heat pump. Always check the HES website directly, as eligibility moves around.

ECO4 is a supplier-funded scheme for low-income and vulnerable households, and it closes on 31 December 2026. Ofgem's guidance (paragraph 5.220) says a battery can be installed during an ECO4 retrofit, but it isn't an ECO4 measure in its own right and doesn't count towards the scheme's scoring. Don't expect ECO4 to pay for a battery on its own.
