Compare Smart Export Guarantee (SEG) rates
With solar panels you can sell surplus electricity back to the grid. Each supplier sets its own export rate, so the tariff you choose makes a real difference to what you earn. Compare the main UK SEG tariffs and estimate your yearly earnings below.
A typical 4kW system without a battery exports roughly 2,000 kWh a year. Not sure? Use our solar estimator to estimate yours.

Rates correct as of September 2026and shown for guidance only. Suppliers can change SEG rates with around 30 days' notice, and eligibility conditions vary. Estimated earnings are a simple illustration (your export volume × the flat rate) and assume you qualify for the tariff; time-of-use and tracker tariffs depend on when you export. Always confirm the live rate and terms directly with the supplier before switching. My Energy Expert is not an energy supplier and does not arrange export tariffs.
How the Smart Export Guarantee works
The Smart Export Guarantee (SEG) requires larger energy suppliers to pay you for electricity your solar panels export to the grid. You're paid per kWh exported, at a rate each supplier sets itself. That's why the same exported energy can earn very different amounts depending on the tariff you're on.
To qualify you'll need a smart meter that can send half-hourly export readings, and a valid MCS certificate(or Flexi-Orb equivalent) for your installation. That's one more reason it pays to use an MCS-certified installer: without the certificate, most suppliers won't pay you SEG at all.
Thinking about solar or a battery?
A good export tariff is only worth as much as the system generating the surplus. Get matched with up to 3 vetted, MCS-certified installers and compare quotes. Free, no obligation.

What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) is a UK government scheme that requires larger energy suppliers to pay solar panel owners for surplus electricity they export to the grid. Each supplier sets its own SEG rate and tariff terms, so the amount you earn per exported kWh varies widely between suppliers.
Do I have to buy my electricity from the same supplier I sell exports to?
Not always. Some SEG export tariffs are open to everyone, so you can keep a cheap import tariff with one supplier and sell your exports to another. However, the highest flat rates and time-of-use tariffs (such as Octopus Flux) usually require you to also take that supplier's import tariff.
What do I need to qualify for SEG payments?
You need a smart meter capable of half-hourly export readings, and a valid MCS certificate (or Flexi-Orb equivalent) for your solar installation. This is one reason it matters that your panels are fitted by an MCS-certified installer. Without that certificate most suppliers won't pay you SEG.
Can I still get SEG payments if I have a battery?
Yes. You can receive SEG payments with a battery, provided the exported electricity originated from your MCS-certified solar panels rather than from the grid. Some of the highest export rates, such as Octopus Intelligent Flux, are specifically designed for homes with a compatible battery.
Are flat or variable SEG rates better?
A flat rate pays the same per kWh whenever you export, which is simple and predictable. Variable or time-of-use rates pay more at peak demand times but less at midday when most solar is exported. They tend to suit homes with a battery that can hold energy back and export during peak periods.
