EDF Energy SEG export tariff — Export Exclusive 18p, September 2026
EDF's Export Exclusive 12m V3 pays 18p/kWh, fixed for 12 months — one of the highest locked-in flat export rates on the UK market. A typical 4kW system exporting ~2,400 kWh a year earns an estimated £432/yr; on a legacy 5p deal that's roughly £312/yr left on the table.
- 18p/kWh fixed for 12 months — no mid-contract cuts (verified September 2026).
- Among the top fixed flat export deals — only Good Energy's variable 25p and battery time-of-use tariffs pay more per unit.
- Requires EDF import + system ≤5kW — larger arrays should look at Good Energy or Octopus.
Is EDF's 18p Export Exclusive right for you?
Export Exclusive 12m V3 is EDF's fixed alternative to Good Energy's 25p flat — with one decisive difference. EDF's 18p is contractually fixed for 12 months; Good Energy's 25p is variable at the supplier's discretion. The 7p you give up (~£168/yr) buys a full year of certainty. The catch: you must import your electricity from EDF, and your system must be 5kW or smaller.

EDF Export Exclusive vs the market — September 2026 rates
How EDF's 18p fixed rate stacks up this month — watch the rate types, which behave very differently over a year.
| Supplier & tariff | Export rate & type | Key conditions |
|---|---|---|
| EDF Export Exclusive 12m V3 | 18p/kWh — 12-month fixed | EDF import customer; system ≤5kW |
| Good Energy Solar Savings Exclusive | 25p/kWh — flat (variable) | Good Energy import customer |
| Octopus Intelligent Flux (closed) | up to 32.17p/kWh — time-of-use peak | Battery + Octopus electricity import |
| E.ON Next (Next Export Exclusive) | 13p/kWh — flat | E.ON Next import customer |
| British Gas Export & Earn Plus | 15.1p/kWh — flat | British Gas dual-fuel customer |
| Default / legacy SEG contracts | 5–7p/kWh — flat | Old contracts signed 2020–2021, often 5p |
All rates verified September 2026. SEG rates are set by suppliers, not Ofgem, and can change or be withdrawn for new customers at any time.
Why a fixed 18p can beat a variable 25p
Good Energy's 25p is the highest non-battery SEG rate in the UK (verified September 2026), but it's variable: the supplier can cut it at its discretion. EDF pays 7p less — about £168/yr on 2,400 kWh — for a rate that cannot move for 12 months. SEG rates sit outside the Ofgem price cap, so a fix is the only way to guarantee your export income.
Octopus Intelligent Flux is now closed to new customers (since March 2026); it paid up to 32.17p/kWh only in peak time-of-use windows — without a battery to shift export into the early evening, the blended rate often lands below a flat 24–25p. For a battery-free household wanting a locked rate, EDF is among the strongest deals on the market.
The 5kW limit — read this before you apply
Export Exclusive 12m V3 is only available for systems of 5kW or less, as recorded on your MCS certificate. That covers most UK domestic installs, but larger arrays are off the table — check your certificate before applying.
Over 5kW? Your strongest moves are Good Energy's 25p flat (variable) or, with a battery, Octopus Flux at up to 29.32p / Intelligent Flux (closed to new customers) — both covered in our SEG rates comparison.
Eligibility checklist for EDF Export Exclusive 12m V3
EDF import + system ≤5kW
This is a bundled tariff — you must buy your electricity from EDF, and the installed capacity on your MCS certificate must not exceed 5kW.
MCS certificate + SMETS2 meter
Standard SEG requirements: an MCS certificate (your installer provides it) and a SMETS2 smart meter — or a DCC-migrated SMETS1 — for half-hourly export readings.
No FIT deemed export or live SEG deal
You can't take FIT deemed export and SEG at once — FIT recipients can opt out of deemed export. Leaving another SEG deal needs 14 days' written notice.
How to switch to EDF's 18p export tariff
- Check the whole package. Export Exclusive requires EDF import — our EDF Energy supplier profile covers that side.
- Gather your details: MCS certificate number, panel capacity in kW (≤5kW), battery capacity if any, your MPAN, and a current export reading.
- Switch your import to EDF (skip if already a customer), then apply for Export Exclusive 12m V3.
- Give your old SEG supplier 14 days' written notice if you're leaving an existing export contract.
- Wait for registration — typically 5–10 working days, then the fixed 18p applies to your metered export.

What 18p/kWh is worth: estimated annual export income
Based on a typical 4kW system generating ~4,800 kWh a year and exporting half (~2,400 kWh). Estimates only — rates change.
| Export rate | Est. income (2,400 kWh/yr) |
|---|---|
| Good Energy — 25p flat (variable) | £600/yr — +£168 vs EDF, but no rate guarantee |
| EDF Export Exclusive — 18p fixed | £432/yr — locked for 12 months |
| E.ON Next — 13p flat | £312/yr — £120 less than EDF |
| British Gas — 15.1p flat | £362/yr — £70 less than EDF |
| Legacy SEG contract — 5p | £120/yr — switching to EDF adds est. £312/yr |
All rates verified September 2026. SEG income is generally income-tax-exempt for owner-occupiers under HMRC micro-generation rules.
EDF SEG export tariff — FAQs
What does the 12-month fix actually mean?
EDF pays 18p/kWh for every exported unit for 12 months from sign-up and cannot reduce the rate during the term. Variable flat rivals like Good Energy's 25p carry no such guarantee.
What if my solar system is over 5kW?
You won't qualify — the tariff is limited to systems of 5kW or less per your MCS certificate. Larger systems should look at Good Energy's 25p flat rate or, with a battery, Octopus Flux (up to 29.32p) or Intelligent Flux (closed to new customers).
Do I have to buy my electricity from EDF to get the 18p rate?
Yes. Export Exclusive is a bundled tariff, only available to EDF import customers. SEG rules normally let import and export suppliers differ, but exclusive deals like this bundle them.
What happens at the end of the 12 months?
The fix ends and you'll move to whatever export deal EDF then offers, which may pay less than 18p. Diarise your end date and re-shop a few weeks before; you can leave a SEG contract with 14 days' written notice.
What meter do I need?
A SMETS2 smart meter, or a SMETS1 migrated to the DCC network — SEG payments are based on half-hourly export readings.
I'm on an old 5p SEG deal — how much more would EDF pay?
Contracts signed in 2020–2021 often pay ~5p/kWh — £120/yr on 2,400 kWh of export. EDF's 18p fixed would pay an estimated £432/yr on the same export, roughly £312/yr more — generally income-tax-free for owner-occupiers.
Lock in a competitive export rate before the October price cap
The Ofgem price cap has sat at £1,663/yr for a typical dual-fuel home since 1 July 2026, and Ofgem has confirmed it rises to £1,724/yr from 1 October 2026 on the updated consumption basis. A strong export tariff pushes the other way: 2,400 kWh at EDF's fixed 18p is an estimated £432/yr back, more than offsetting the cap rise for many solar homes. Exclusive deals get withdrawn — compare while the 18p fix is on the table with a full energy quote.
