Explore the chart. Hover, focus or select any point to see its exact values.
Points are interactive: hover, focus or select one for exact values. Shaded band is the lowest-to-highest paid spread within each month; the line is the duration-weighted mean. One period is drawn from part of the calendar rather than all of it: Sept 2026 (9 of 30 days). A month is partly counted where a version went on or came off sale inside it, and the current month is always still in progress. They are drawn hollow.
Each month shows the version of Octopus SEG you could actually have signed up to then, so the line follows the tariff through its successive versions rather than any one product code. Older versions carry on publishing rates for months after they stop selling; those are not averaged in, because nobody could buy them. Drawn from the stored daily rollups across every payment method the tariff publishes; where a tariff publishes more than one, the rates above show the direct-debit one and this line sits between them.

There is no price cap comparison on this page. The cap limits what a supplier can charge you, not what it pays you for export, so comparing an export rate against it would compare against a number that does not apply.

About Octopus SEG
Octopus SEG is a legacy Smart Export Guarantee arrangement: an export product from the scheme that succeeded the Feed-in Tariff, paying a flat rate for the electricity you send to the grid. Its unit rate was last set on 1 February 2022 and has not changed since, but the product remains open for existing customers and that rate remains in force today rather than having lapsed or expired. The figure shown here is that same unchanged rate, not a stale or missing one.
