Question 1

What is the best SEG rate in the UK?

Accepted Answer

As of March 2026, the best standard SEG rate is 24p/kWh from Octopus Energy's Outgoing Octopus tariff. For those who can time their exports, Octopus Outgoing Agile can pay up to 35p/kWh during peak demand periods.

Question 2

Can I switch my SEG supplier independently?

Accepted Answer

Yes. Your SEG supplier can be completely different from your electricity supplier. You can switch SEG suppliers without changing who provides your electricity. This means Scottish Power customers can use Octopus for SEG exports while keeping Scottish Power for their electricity supply.

Question 3

What SEG rate do Scottish Power customers get?

Accepted Answer

Scottish Power's SEG rate is 8p/kWh, which is significantly below the UK average of 12p/kWh and well below the best rate of 24p/kWh. Scottish Power customers should consider switching to a better SEG tariff.

Question 4

How does battery storage help with SEG income?

Accepted Answer

Battery storage allows you to store solar electricity and export it when SEG rates are highest. With tariffs like Octopus Outgoing Agile that pay different rates throughout the day, you can export during peak hours (typically 4-7pm) when rates can exceed 35p/kWh, rather than exporting during the day when rates are lower.

Question 5

Are SEG rates available in Scotland?

Accepted Answer

Yes, all major SEG tariffs are available throughout Scotland. The Smart Export Guarantee is a UK-wide scheme. Scottish homeowners have access to the same rates as the rest of the UK, including Octopus Energy's 24p/kWh Outgoing tariff.
