Octopus Energy SEG export tariffs — August 2026 rates
Octopus offers some of the UK's higher peak export rates for solar-and-battery homes — with conditions. Peaks apply only in the early evening, and every export tariff requires Octopus import.
- Intelligent Flux — up to 32.17p/kWh peak (closed to new customers since March 2026): existing customers only; needs an Octopus-controlled battery.
- Flux — peak-time export with a battery: self-managed solar + battery time-of-use tariff (rate varies).
- Outgoing — ~12p/kWh flat: the simple panels-only option.
What 2,400 kWh of exported solar earns per year
A typical 4kW system generates ~4,800 kWh a year, half exported — about 2,400 kWh. Time-of-use rows show the peak-rate ceiling; real blended income is lower.
| Tariff | Estimated annual income (2,400 kWh) |
|---|---|
| Octopus Intelligent Flux (closed to new customers; was up to 32.17p/kWh) | up to ~£772 — peak ceiling |
| Octopus Flux (battery, peak-time export) | up to ~£704 — peak ceiling |
| Good Energy Solar Savings Exclusive (25p/kWh flat) | £600 |
| EDF Export Exclusive 12m V3 (18p/kWh fixed) | £576 |
| Octopus Outgoing (~12p/kWh flat) | £288 |
| Legacy 5p SEG contract (5p/kWh flat) | £120 |
Estimated, verified August 2026; actual income varies with generation, export share and blending. SEG income is generally income-tax-exempt for owner-occupiers.
Octopus SEG export tariff FAQs
Do I need a battery for Octopus Flux?
Yes — Flux requires panels plus a battery and Octopus import. Without one you can't reach the evening peak where the evening peak rate applies; panels-only homes should pick Outgoing (~12p flat) or a higher flat rate elsewhere.
Can I get Octopus Outgoing without switching my import to Octopus?
No — Outgoing, like Flux and Intelligent Flux, is only for Octopus import customers. To keep your supplier, you'd need their export tariff or an open-market SEG tariff, which pay far less.
Is Intelligent Flux worth it without a battery?
No — and it isn't available without one. The up-to-32.17p/kWh peak (on the now-closed Intelligent Flux) came from discharging an Octopus-controlled battery into evening windows; panels alone can't do that.
What happens to my SEG if I leave Octopus for import?
Your export tariff ends with it — import is a condition of all three. Register a new SEG tariff with your new supplier, give 14 days' written notice on the old one, and plan the export side first so you don't drop onto a low default rate.
What do I need to qualify?
An MCS-certified installation, a SMETS2 smart meter (or DCC-migrated SMETS1) with half-hourly export readings, and an Octopus import account.
Are Octopus export rates protected by the price cap?
No — SEG rates are set commercially and Octopus can change them at its discretion. The cap only governs imported energy, having risen 1 July 2026 to £1,663/yr typical.

The Ofgem price cap rose 1 July 2026 to £1,663/yr typical — up 13%, an extra £221 a year. Export income offsets it directly: up to ~£772/yr at Intelligent Flux's peak ceiling with a battery, or £600/yr on a 25p flat rate without one (estimated, 2,400 kWh exported).
