What is the best Smart Export Guarantee rate in the UK in 2026?

As of April 2026, Octopus Energy offers the best fixed Smart Export Guarantee rate at approximately 24p per kWh through their Outgoing Octopus tariff, with no minimum export requirement and no obligation to buy electricity from Octopus. For battery owners with a smart meter, Octopus Flux offers variable rates reaching approximately 35p per kWh during peak hours between 16:00 and 19:00, which can outperform the fixed rate when exports are timed to the peak window.

Can I switch SEG provider without changing my electricity supplier?

Yes. The Smart Export Guarantee is entirely independent of your electricity supply contract. You can export with Octopus Energy at 24p per kWh while buying your electricity from British Gas, Scottish Power, or any other supplier. Switching SEG provider does not affect your electricity bill or supply. Many solar owners are unaware of this and leave hundreds of pounds per year unclaimed by staying with a lower-rate provider.

How much can I earn from exporting solar electricity in Scotland?

A 4kW solar system in Scotland exports approximately 1,650 to 1,750 kWh per year without a battery, rising to around 900 to 1,000 kWh even with a battery increasing self-consumption. At the Octopus rate of 24p per kWh this earns approximately £396 to £420 per year from export alone. Without a battery and on the worst rate of 11p, the same system earns only £182 to £193, a difference of over £220 per year.
