Best Tariff for Solar and Battery Homes in Scotland (2026)

If you have solar panels and a home battery in Scotland, the best tariff for solar and battery comes down to one question: is there also an electric car charging on your drive? Without one, Octopus Flux is the tariff to beat. On 6 October 2026 it charged 14.27p/kWh between 2am and 5am in South Scotland and paid 27.19p/kWh for electricity exported between 4pm and 7pm. With a compatible EV, Intelligent Octopus Go plus a separate export tariff usually comes out ahead. Below we compare every pairing worth a look, region by region, and finish with a decision table.

Every rate is the supplier's own figure, checked on 6 October 2026, and carries no VAT: household electricity in Great Britain is zero-rated from 1 October 2026 to 31 March 2027.

Check three things before you compare

Start with your region. Octopus, E.ON Next and EDF price Scotland as two regions that follow the electricity network areas: South Scotland, where SP Energy Networks runs the wires, and North Scotland, where SSEN does. We ran postcodes through Octopus's own region lookup. Livingston, Edinburgh, Glasgow, central Stirling, Alloa, Falkirk, Dunfermline and Hamilton came back as South Scotland; Dundee, Perth, Dunblane, Kinross, Aberdeen and Inverness came back as North Scotland. The line runs through the Stirling and Clackmannanshire area, where some FK8, FK9 and FK14 postcodes are North Scotland, so check your own. Our energy supplier vs network operator guide explains why the network decides it.

Next, know your yardstick. Ofgem's price cap for Direct Debit customers from 1 October to 31 December 2026 is 26.11p/kWh plus 61.41p a day in South Scotland, and 26.35p/kWh plus 55.14p a day in North Scotland. A time of use tariff only earns its keep if your battery keeps you out of its expensive hours often enough to beat that flat rate.

Finally, check your meter. Every tariff here needs a smart meter that sends half-hourly readings, and Octopus accepts a SMETS2 or a SMETS1 made by Secure. If you still have an older two-rate meter, read our guide to Economy 7 and Economy 10 first.

Octopus Flux: the default for solar and battery without an EV

Flux bundles import and export into one tariff with three daily bands. Octopus asks for solar panels, a home battery, a half-hourly smart meter and Octopus as both import and export supplier, plus a copy of your MCS certificate. There are no exit fees, and Flux was open to new sign-ups when we checked.

Octopus's tariff data shows both standing charges rising from 19 October 2026, to 61.44p a day in South Scotland and 55.28p in North Scotland. Flux suits a battery big enough to cover most of the 4pm to 7pm peak with something left to export. Scheduling and sign-up steps are in our Octopus Flux tariff guide.

Intelligent Octopus Flux: mostly closed for now

Intelligent Flux hands a compatible battery to Octopus to charge and export for you. On 6 October 2026 its South Scotland import rate was 19.67p outside 4pm to 7pm and 26.22p inside it (North Scotland: 20.17p and 26.89p). The catch is availability: Octopus says it is currently exclusive to customers who bought their solar panels and battery from Octopus, so for most Scottish homes it is not an option. Its compatibility list includes Tesla, GivEnergy, Sigenergy and EcoFlow among eleven brands.

Octopus's suggested alternative is Charge Pack, an add-on rather than a tariff. It sits on top of Intelligent Octopus Go, Octopus Go, Flexible or a fixed Octopus import tariff with Outgoing Octopus for export, runs a supported battery through around two grid sessions a week and guarantees at least £12 a month in credit. Supported batteries include GivEnergy, Sigenergy and EcoFlow, with Tesla listed as coming soon. It cannot be combined with Flux.

Octopus Agile and Agile Outgoing: how a battery uses half-hourly prices

Agile sets a new price for every half hour, tied to the wholesale market, separately for each of Octopus's 14 regions, and publishes tomorrow's prices between 4pm and 8pm today. Price Cap Protect stops any half hour going above 100p/kWh including VAT, and when prices drop below zero Agile pays you to use electricity. Agile Outgoing prices your export the same way.

A battery earns on Agile by charging in the cheapest half hours and covering the house through the dearest ones, usually 4pm to 7pm, which in practice needs automation that reads Octopus's prices. Here is what Agile did in Scotland over the 29 days from 7 September to 5 October 2026, shown without VAT because that is what you pay now:

North Scotland follows the same half-hourly pattern as South Scotland but sits higher, averaging 32.16p across every half hour against 28.03p. The cheapest power mostly came around midday rather than overnight: 125 of the 174 cheapest half hours fell between 11am and 4pm, when solar is often filling the battery anyway, so Agile's grid top-ups matter most in the dark months. And Agile Outgoing never paid below zero, but its 4pm to 7pm average was below Flux's 27.19p for the same window.

The risk sits in the evening. Every peak half hour your battery cannot cover is bought at the going rate, which averaged 46.66p in South Scotland and touched 87.29p. Octopus has told customers that wholesale prices rose sharply after Middle East conflict disrupted gas shipments from March 2026, and that leaving a dynamic tariff such as Agile can lock you out of rejoining for up to nine months. Agile suits a battery that is large relative to your evening use. It pairs with Agile Outgoing, with Outgoing Octopus at a flat 12p/kWh, or with Prime Outgoing at 16p from 4pm to 7pm and 9p otherwise.

Intelligent Octopus Go and Octopus Go: when there's an EV on the drive

Intelligent Octopus Go is built for EV charging, but the whole home gets its 7.6p/kWh rate from 11:30pm to 5:30am, and Octopus's own tariff guide suggests using those hours to fill a home battery, then use or sell that energy. The trade-off is a day rate of 36.37p in South Scotland and 37.65p in North Scotland, with standing charges of 61.44p and 55.28p a day. It is only offered as a 12-month fix for now, with a £50 exit fee, and your car or charger must be on Octopus's compatible list.

Octopus Go works with any EV and charger: 9.5p/kWh from 12:30am to 5:30am, then 34.97p in South Scotland or 36.25p in North Scotland, also fixed-only with a £50 exit fee. We compare these with E.ON Next, EDF, British Gas, OVO and ScottishPower's EV deals in our guide to the best EV tariffs.

Cosy Octopus for heat pump homes

Cosy has three cheap windows a day (4am to 7am, 1pm to 4pm and 10pm to midnight) at 12.19p/kWh in South Scotland and 12.50p in North Scotland on the flexible version, with a 4pm to 7pm peak of 37.28p and 38.23p. It needs a heat pump, electric radiators or an electric boiler, and for a heat pump home with solar and a battery Octopus still recommends Flux. Our guide to heat pump tariffs has the detail.

Time of use offers from E.ON Next, British Gas, EDF, OVO and ScottishPower

These are the battery-relevant offers on each supplier's own site on 6 October 2026; where prices only appear on a personalised quote, we say so.

If you have solar but no battery yet, export matters more than a time of use import tariff, so compare our SEG export rates first.

What the differences between tariffs are worth

Two numbers decide most of this: the gap between a tariff's cheap and expensive hours, and the price of whatever you cannot shift. The table shows what moving one kilowatt-hour into the cheap band is worth at 6 October 2026 rates (Agile uses the 29-day averages above).

Now set that against the price of power you cannot shift. Flux's rest-of-day rate in South Scotland is 23.77p, below the 26.11p cap, while Intelligent Octopus Go's day rate is 12.6p higher. So one full cycle of a 10kWh battery, before losses, is worth £2.88 on Intelligent Octopus Go against £1.90 on Flux, but only while battery and panels genuinely cover the day, because every kilowatt-hour they miss costs 12.6p more than on Flux. On export, Flux pays 15.2p more than Outgoing Octopus for each kilowatt-hour sent out between 4pm and 7pm in South Scotland.

Best tariff for battery storage: the decision table

Tariffs change faster than hardware, so choose a battery that can follow more than one of them. Our guide to solar panels with battery storage covers how a system is sized around your usage and tariff, and home battery storage explains the batteries we fit, including Tesla Powerwall, Sigenergy and EcoFlow PowerOcean. Already have panels? You can add a battery to existing solar. Our in-house team and vetted MCS-certified trade partners compare these tariffs against your own usage at survey. Get your free quote.
