Octopus Energy Tariffs Scotland: Complete Optimization Guide 2024

Octopus Energy offers a range of smart tariffs that can work very well for Scottish homes with solar panels, battery storage, an electric vehicle or a heat pump. This guide explains how the main tariff types work in general terms, so you can judge which might suit your home. Rates change regularly, so always check the supplier's current rates before switching.

How Time-of-Use Tariffs Work

A standard tariff charges the same price for electricity whatever time you use it. A time-of-use tariff charges different prices at different times of day. Electricity is usually cheaper overnight and at other quiet times, and more expensive during the late afternoon and early evening peak, when demand on the grid is highest.

On their own, these tariffs reward households who can shift usage. Paired with a home battery, they become much more useful: the battery charges when electricity is cheaper and powers your home when it is more expensive, without you changing your routine.

Octopus Tariff Types Explained

Octopus Go

Go offers a cheaper fixed rate for a set window each night, with a standard rate the rest of the day. It is designed for EV owners but also suits battery owners who want a simple, predictable schedule: the battery fills during the cheap window and discharges through the day and evening.

Octopus Intelligent Go

Intelligent Go works with compatible EVs and chargers, and in some cases batteries. Octopus can schedule charging in cheaper periods automatically. Check eligibility, as it depends on your equipment.

Octopus Agile

Agile prices change every half hour based on wholesale electricity costs, with prices published in advance. Cheap periods often fall overnight or during windy, low-demand spells, and prices can occasionally go below zero. Peak prices can be high, so Agile suits homes with a battery and a system that can respond automatically to price signals.

Octopus Flux

Flux is built for homes with solar and a battery. It has cheaper import overnight, higher prices at peak, and pays different export rates through the day, rewarding homes that export stored energy at peak times. It usually requires both solar and a battery.

Octopus Cosy

Cosy is aimed at heat pump owners, with cheaper periods during the day and night that let a heat pump warm the home before the peak.

Export Tariffs

If you have solar panels, you can be paid for the electricity you send to the grid under the Smart Export Guarantee. Octopus offers export options including fixed-rate and variable versions, and Flux combines import and export in one tariff. Export tariffs usually need an export-capable smart meter and evidence that your system was installed by an MCS-certified installer. We install through MCS-certified partners.

Choosing a Tariff for Your Scottish Home

• Battery, no solar: an overnight tariff such as Go, or Agile if your battery can respond automatically.
• Solar and battery: compare Flux with an overnight tariff plus a separate export tariff.
• Electric vehicle: Go or Intelligent Go, with any home battery sharing the cheap window.
• Heat pump: Cosy is worth comparing, especially if you also have a battery.

Your daily routine matters too. Households who are out during the day, those working from home and those with electric heating all use electricity differently.

Scottish Considerations

Short winter days and long summer evenings

In winter, solar output is low and days are short, so cheap overnight charging does more of the work for battery owners. In summer, especially in the north, long days mean solar can fill the battery and export the surplus. A tariff that works well in both seasons is valuable.

Electric heating and older homes

Many Scottish homes, particularly flats, tenements and rural properties off the gas grid, use electric storage heaters on older off-peak meters. Moving to a smart tariff may mean changing meters and heating controls, so ask for advice before switching.

Smart meters and connections

Most smart tariffs need a working smart meter. Smart meter signal can be patchy in some rural parts of the Highlands and Islands, so check it before relying on a tariff that needs half-hourly readings. If you add solar or a battery, your installer will also notify or apply to the network operator, SP Energy Networks in central and southern Scotland or SSEN in the north, under G98 or G99.

Practical Tips

• Check the supplier's current rates and eligibility before switching, as both change.
• Review a year of usage data to understand your pattern across seasons.
• Make sure your battery or inverter can be scheduled or controlled automatically.
• Revisit your tariff periodically.
