Octopus Energy SEG export tariffs — June 2026 rates
Octopus pays the highest peak export rates of any UK SEG supplier — with conditions. Peaks apply only in the early evening, and every export tariff requires Octopus import.
- Intelligent Flux — up to 32.17p/kWh peak: the UK's highest SEG rate; needs an Octopus-controlled battery.
- Flux — up to 29.32p/kWh peak: self-managed solar + battery time-of-use tariff.
- Outgoing — ~12p/kWh flat: the simple panels-only option.
Is an Octopus export tariff right for your home?
It comes down to one question: do you have a home battery? With one, Flux or Intelligent Flux can out-earn every flat-rate SEG tariff by storing midday generation for the high-paying evening window. Without one, Outgoing's ~12p/kWh is comfortably beaten by Good Energy's 25p/kWh and EDF's 24p/kWh — see all UK SEG export rates compared.
The second question: will you move your import to Octopus? Its 12-month fix is competitive at around £1,632/yr typical use (verified June 2026), but if you're on a cheap fix elsewhere, weigh the whole package, not just the export rate.

Octopus export rates vs the alternatives — June 2026
Time-of-use peaks apply only in evening windows — flat tariffs pay the same on every unit, all day.
| Tariff | Export rate & type | Key requirements |
|---|---|---|
| Octopus Intelligent Flux | up to 32.17p/kWh — time-of-use peak | Compatible battery + Octopus import |
| Octopus Flux | up to 29.32p/kWh — time-of-use peak | Solar + battery, Octopus import |
| Octopus Outgoing | ~12p/kWh — flat | Octopus import customer; no battery needed |
| Good Energy Solar Savings Exclusive | 25p/kWh — flat | Good Energy import customer |
| EDF Export Exclusive 12m V2 | 24p/kWh — 12-month fixed | EDF import customer, system ≤5kW |
| Default / legacy SEG floor | 5–7p/kWh — flat | Old contracts signed 2020–2021, often 5p |
All rates verified June 2026; rates change and SEG rates are not price-cap regulated.
The three Octopus export tariffs — and who each suits
Intelligent Flux — up to 32.17p/kWh
The UK's highest SEG peak rate, verified June 2026. Octopus automates a compatible battery — charging cheap, exporting when prices spike. Battery-only.
Flux — up to 29.32p/kWh
The self-managed option for solar-plus-battery homes: peak export pays in the early evening, cheap overnight import fills the battery.
Outgoing — ~12p/kWh flat
Simple flat rate for panels-only homes — no time windows to manage. The trade-off: ~12p is less than half Good Energy's 25p flat.
Judge the whole package: see the Octopus Energy supplier profile and import tariff line-up.
How the blended time-of-use rate really works
The 32.17p and 29.32p figures are peak rates, not what every unit earns. Top rates pay in the early-evening demand peak — but panels generate most around midday, so unstored export lands in cheaper daytime bands.
A battery transforms the maths: store the midday surplus, discharge into the evening peak, and a large share of your export earns the headline rate. Without one, your blended average often lands below a flat 25p deal — why Octopus gates both behind battery ownership. See the best UK solar panel and battery tariffs for 2026.
Won't move your import? Good Energy 25p vs EDF 24p
Without a battery, the strongest deals are Good Energy's 25p/kWh flat and EDF's Export Exclusive 12m V2 at 24p/kWh fixed (systems ≤5kW). Both also bundle import.
Under Ofgem's SEG rules import and export suppliers can differ — but open-market tariffs pay far less, so the bundled exclusives usually win.
How to switch to an Octopus export tariff
- Check your kit qualifies: MCS certificate plus a SMETS2 smart meter (or DCC-migrated SMETS1) taking half-hourly export readings; for Flux/Intelligent Flux, the right battery.
- Move (or confirm) your import with Octopus — all three export tariffs require it.
- Gather your details: MCS certificate number, panel kW, battery capacity, MPAN and an export reading.
- Apply. Registration typically completes in 5–10 working days.
- Cancel your old SEG with 14 days' written notice so payments hand over cleanly. Unsure? Get a personalised quote first.
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 (battery, up to 32.17p/kWh) | up to ~£772 — peak ceiling |
| Octopus Flux (battery, up to 29.32p/kWh) | up to ~£704 — peak ceiling |
| Good Energy Solar Savings Exclusive (25p/kWh flat) | £600 |
| EDF Export Exclusive 12m V2 (24p/kWh fixed) | £576 |
| Octopus Outgoing (~12p/kWh flat) | £288 |
| Legacy 5p SEG contract (5p/kWh flat) | £120 |
Estimated, verified June 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 up to 29.32p/kWh 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 comes 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, rising 1 July 2026 to £1,862/yr typical.
Lock in your export income before the July price rise
The Ofgem price cap rises 1 July 2026 to £1,862/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). Compare Octopus against the whole market in under two minutes.
