Key Takeaways
- Fuse pays 13p/kWh for exported solar — the best flat rate you can get without switching import supplier.
- Open to all: keep your current electricity supplier and still earn 13p on export.
- Beats Octopus Outgoing (12p) on a like-for-like flat-rate, open-to-all basis.
- But storing beats exporting: a battery avoids ~26p/kWh import — almost double the 13p export value.
If you have solar panels, the Smart Export Guarantee (SEG) pays you for the electricity you send back to the grid. Rates vary hugely between suppliers — from as little as 1p/kWh to over 30p/kWh on premium battery-only tariffs. Among open-to-all tariffs (the ones you can join without switching your electricity import supplier), Fuse Energy's 13p/kWh leads the market in 2026.
What is the Fuse Energy SEG tariff?
Fuse Energy offers a single flat-rate SEG tariff paying 13p for every kWh you export. As of 1 April 2026, Fuse became a mandatory SEG licensee, meaning it must offer an export tariff to eligible solar households. What sets Fuse apart is that the 13p rate is available to any solar owner — you don't have to buy your imported electricity from Fuse to claim it.
That's important. Most of the headline-grabbing export rates (Good Energy 25p, EDF 24p, OVO 20p) are installer-exclusive or require you to take that supplier's import tariff too. Fuse keeps it simple: solar in, 13p out, regardless of who you buy power from.
Fuse Energy vs other open-to-all SEG tariffs
Comparing only tariffs you can join without switching your import supplier (June 2026):
| Supplier | Tariff | Export rate | Notes |
|---|---|---|---|
| Fuse Energy | Single Rate SEG | 13p | Best open-to-all flat rate. Mandatory SEG licensee since 1 April 2026. |
| ScottishPower | SmartGen | 6p | Open to all — no import switch needed. |
| E.ON Next | Next Flex Export | 6p | Open to all — no import switch needed. |
| Octopus Energy | Octopus SEG | 4.1p | Unbundled — any solar owner, any import supplier. |
| British Gas | Export & Earn Flex | 3.0p | Standard SEG fallback. |
| EDF Energy | Export Variable Value | 3.0p | Standard SEG fallback. |
Rates compiled June 2026 from publicly published SEG tariffs. SEG is unregulated, so suppliers can change rates at any time — always confirm the current rate before switching. For the full ranking including installer-exclusive and battery-only tariffs, see our best SEG export rates guide.
Who qualifies for the Fuse SEG tariff?
Fuse SEG eligibility checklist
- ✓ Solar PV (or other eligible renewable) of 5MW or less — every home setup qualifies
- ✓ An MCS certificate for your installation
- ✓ A SMETS2 smart meter that records half-hourly export
- ✓ You can keep any electricity import supplier — no switch required
Why a battery earns more than exporting to Fuse
Here's the maths most solar owners miss. Exporting a unit of solar to Fuse earns you 13p. But if you store that same unit in a battery and use it in the evening, you avoid buying a unit from the grid at roughly 26p. That's almost double the value for exactly the same kWh of solar.
The smartest setup is both: a battery soaks up your daytime solar so you use it after dark, and you export only the genuine surplus to Fuse at 13p. A plug-in AC-coupled battery makes this effortless — it pairs with your smart meter to automatically store excess solar, with no rewiring and no electrician.
Already have solar?
A plug-in battery retrofits to your existing panels in minutes — no new inverter, no MCS install. Capture the solar you're currently exporting for pennies and use it when the sun's down.

What is the Fuse Energy SEG export rate?
Fuse pays 13p/kWh on every unit of solar you export — the best open-to-all SEG flat rate in the UK for 2026.
Do I have to switch to Fuse for my electricity?
No. The Fuse SEG tariff is open to all solar owners regardless of who supplies your imported electricity. You keep your current import deal and still earn 13p on export.
Is Fuse better than Octopus Outgoing?
On a flat-rate, open-to-all basis, yes — Fuse's 13p beats Octopus Outgoing's 12p, and Octopus requires you to be an import customer. Octopus's time-of-use export tariffs can pay more, but only if you can dispatch from a battery.
Should I export to Fuse or store solar in a battery?
Store first, export the surplus. Avoiding ~26p/kWh import is worth almost double Fuse's 13p export. A battery plus Fuse export gives you the best of both.
