Long-term context

The last 48 months across Great Britain

Octopus SEG monthly rates averaged across the regions of Great BritainOctopus SEG monthly rates averaged across the regions of Great Britain from Oct 2022 to Sept 2026. Ranges from 3.10p to 5.10p per kWh. Most recent period Sept 2026: 4.10p per kWh, counted from 10 of 30 days. One period is drawn from part of the calendar rather than all of it: Sept 2026 (10 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.3.10p3.60p4.10p4.60p5.10pOct 2022Oct 23Sept 24Sept 25Sept 20264.10p latest

Points are interactive: hover, focus or select one for exact values. The line is the plain average of the regional monthly means — all 14 regions, in every month — and the shaded band runs from the lowest-paying of those regions to the highest-paying in that month. So the band is the spread BETWEEN regions, not the spread within a month — a regional page’s chart shows the latter. Nobody pays the line; it describes the country rather than a bill. One period is drawn from part of the calendar rather than all of it: Sept 2026 (10 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.

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.

Essentials

You need

  • Eligible generation and an export-capable smart-meter setup confirmed by Octopus.
  • Any required solar eligibility or compatibility confirmed before switching.

Best fit

Works best if

  • You value a simpler rate structure over active half-hourly scheduling.

Check carefully

Watch out for

  • Export rates are payments, not discounts to subtract from an assumed import bill.

Pairing

Compatible export choices

  • This is an export product; verify which import tariff Octopus permits it to be paired with.

Make the final check

How to verify or switch

  1. Check the exact tariff name, product version, regional quote, eligibility and current terms with Octopus Energy.
  2. Use OctoTariffs history and calculators as evidence, not as a supplier quote or guarantee of future cost.

Questions, answered

Why has this rate not changed since 2022?
Because Octopus has not revised it. The rate was set on 1 February 2022 and no newer one has been published since, but the product is still open to existing customers and the rate is still in force, so the figure shown is the genuine current rate rather than an old one left on the page by mistake.
What is the Smart Export Guarantee?
It is the scheme that obliges larger electricity suppliers to pay small generators for the electricity they export to the grid. Each supplier sets its own SEG rate, and that rate is a payment made to you rather than a charge made against you.
Does the Ofgem price cap apply to this tariff?
No. The cap limits what you may be charged for the energy you consume, and it does not apply to a payment made to you for the energy you export, so an SEG rate cannot sensibly be measured against it.
