Best SEG export tariff rates UK — June 2026

If you own solar panels and you are still on the original 5p–5.5p Smart Export Guarantee tariff you signed back in 2020 or 2021, you are leaving £150–£450 a year on the table. Switching your export tariff is now far more important than switching your import tariff, because peak SEG rates have stretched out to 32p/kWh while import rates remain capped. This page lists every major UK SEG export tariff verified June 2026, ranked by headline rate, with eligibility rules and the savings illustration baked in.

  • Top peak rate today: Octopus Intelligent Flux up to 32.17p/kWh (battery + Octopus electricity tariff bundle).
  • Best flat rate: Good Energy Solar Savings Exclusive at 25p/kWh.
  • Best for non-Octopus customers: EDF Export Exclusive 12m V2 at 24p/kWh fixed for twelve months.
  • Ofgem context: July 2026 price cap rises to £1,862/yr (+13%) — export income offsets the import hike.

Compare every UK SEG export tariff in one place

The Smart Export Guarantee replaced the old Feed-in Tariff in January 2020 and obliges every electricity supplier with more than 150,000 customers to publish at least one SEG export tariff. As of June 2026 there are roughly thirty live SEG tariffs across the UK, ranging from a paltry 1p/kWh up to the headline 32.17p/kWh paid by Octopus Intelligent Flux during peak export windows.

How the Smart Export Guarantee actually works

The SEG is a government scheme that obliges every licensed electricity supplier in Great Britain with more than 150,000 domestic customers to offer at least one tariff that pays small-scale low-carbon generators for every kilowatt-hour of electricity they export back to the grid. The scheme covers solar PV up to 5MW, onshore wind, hydro, micro-CHP and anaerobic digestion. For a residential solar owner the practical reality is simple: your smart meter measures every unit you export, the supplier credits your account, and you receive cash or a bill credit either monthly or quarterly.

Crucially, the supplier you import electricity from does NOT have to be the same supplier you sell your exports to. That uncoupling is the lever you should pull in June 2026: you can keep a cheap import tariff (E.ON Next Fixed at £1,602/yr or Octopus 12M Fixed at £1,632/yr both look strong against the July 2026 cap of £1,862/yr) and separately export to Good Energy at 25p/kWh, or to EDF at 24p/kWh. The two contracts are completely independent unless the export tariff explicitly bundles import.

SEG eligibility checklist — verified June 2026

Generation technology

Solar PV, wind, hydro, micro-CHP or anaerobic digestion. Maximum 5MW total declared net capacity (50kW for micro-CHP). Domestic rooftop PV is overwhelmingly the most common applicant.

MCS or equivalent certificate

Your installation must hold MCS certification (or RECC-equivalent for non-MCS technologies). Without this you cannot register for SEG — keep your MCS handover pack safe.

Smart meter (SMETS2 or equivalent)

SEG payments depend on half-hourly export readings. A SMETS2 smart meter is effectively mandatory; SMETS1 is accepted if it has been migrated to the DCC. No smart meter, no SEG income.

How to switch your SEG export tariff in June 2026

  1. Gather your kit details. MCS certificate number, panel kW rating, battery capacity (if any), MPAN from your electricity bill, and a recent smart meter export reading.
  2. Decide flat vs time-of-use. If you have a battery, time-of-use (Octopus Intelligent Flux 32.17p, Octopus Flux 29.32p) almost always pays more. If you have no battery, a flat tariff like Good Energy 25p or EDF Export Exclusive 24p is simpler and competitive.
  3. Check import-tariff bundling. The very best export rates (Flux, Intelligent Flux, EDF Export Exclusive, British Gas Export & Earn Plus, Good Energy Solar Savings Exclusive) require you to be that supplier's electricity import customer too. Factor in the import tariff cost.
  4. Use our comparison form below. We confirm the best supplier match given your kit and region, then pass you the application link directly to the supplier — no aggregator middle fee.
  5. Cancel your old SEG. Notify your existing SEG supplier in writing (email is fine) at least 14 days before switching to avoid double-billing of export readings.

SEG savings illustration — 4kW PV system, June 2026

A typical 4kW domestic solar PV array in the south of England exports roughly 2,400 kWh a year (assuming 50% of 4,800 kWh annual generation is exported and 50% self-consumed). Here is what that exported electricity is worth on each major SEG tariff verified June 2026:

TariffRate (effective)Annual SEG income (2,400 kWh)
Octopus Intelligent Flux (battery)~22p/kWh blended~£528
Octopus Flux (battery)~19p/kWh blended~£456
Good Energy Solar Savings Exclusive25p/kWh flat£600
EDF Export Exclusive 12m V224p/kWh flat£576
British Gas Export & Earn Plus15.1p/kWh flat£362
Ecotricity8.9p/kWh flat£214
Default 5p SEG (old contracts)5p/kWh flat£120

In other words a solar owner stuck on a legacy 5p SEG contract who switches to Good Energy Solar Savings Exclusive at 25p/kWh adds £480/year of export income — money that more than offsets the £221/year price-cap rise hitting from 1 July 2026. Use the comparison form to confirm your eligibility.

Frequently asked questions — SEG export tariffs (June 2026)

What is the highest SEG export rate in the UK in June 2026?

As of late June 2026 the highest peak SEG export rate is Octopus Intelligent Flux at up to 32.17p/kWh during peak export windows, but it requires a battery and an Octopus import tariff. The best flat rate available without a battery requirement is Good Energy Solar Savings Exclusive at 25p/kWh. Run the numbers using our comparison form.

Can I be on a different supplier for import and export?

Yes — the Smart Export Guarantee is fully decoupled from your import supply. You can import from E.ON Next Fixed at £1,602/yr and export to Good Energy at 25p/kWh, as one example. The exception is bundled tariffs like Octopus Flux which require Octopus on both sides. Verified June 2026.

Do I need a smart meter to claim SEG?

Yes. SEG payments are based on half-hourly export readings from a SMETS2 (or DCC-enrolled SMETS1) smart meter. If you have no smart meter your application will be paused until installation — most suppliers will arrange this free as part of onboarding when you sign up via our comparison form.

Will SEG income be affected by the July 2026 price cap?

No — SEG export rates are set independently by each supplier and are not regulated by the Ofgem default tariff price cap. The cap rising to £1,862/yr from 1 July 2026 (+13%) only affects import unit rates and standing charges, but it does make switching to a high-paying SEG tariff considerably more valuable as a net household cost offset.

How long does a SEG switch take to process?

Once you submit the application with MCS certificate, MPAN and meter readings, most suppliers register the new SEG contract within 5–10 working days. First payment or bill credit lands in the next billing cycle thereafter. You should formally cancel your old SEG with 14 days' notice via email — start the switch using our comparison form.

Are time-of-use SEG tariffs (Flux, Intelligent Flux) worth it without a battery?

Generally no. Flux and Intelligent Flux pay their headline 29.32p and 32.17p/kWh during early-evening export windows — exactly when solar generation has already fallen off. Without a battery to time-shift exports, your blended rate may end up below a simple flat 25p/kWh deal like Good Energy. Verified June 2026.

Is SEG income taxable?

For owner-occupiers generating electricity primarily for their own home, SEG income is generally exempt from income tax under HMRC's micro-generation rules. Landlords or business owners should check with HMRC. The freshness on this guidance was last verified June 2026.

Can I switch SEG suppliers if I still have a legacy Feed-in Tariff?

Yes, and you should. The Feed-in Tariff (FIT) and the SEG are separate schemes. You can keep your FIT generation and deemed-export payments running with your original FIT licensee while moving your real (smart-metered) export contract to a high-paying SEG supplier like Octopus Flux 29.32p or EDF 24p. Talk it through via our comparison form.

Lock in the best SEG export rate before 1 July 2026

The July 2026 Ofgem price cap takes effect in 30 days at £1,862/yr (+13% / +£221). Switching from a 5p legacy SEG to a 25p flat rate like Good Energy adds £480/year on a typical 4kW system — more than offsetting the import-side increase. Don't leave that money on the table.
