Solar export rates compared, September 2026

There is no single answer that fits everyone. The highest flat rate we checked was Good Energy's Solar Savings Exclusive at 25p/kWh, and it needs solar and a battery installed by Good Energy itself. Among rates that do not require that, several suppliers publish 12p to 18p with only an import-supply condition attached. The table above shows every rate we checked, its conditions and its source, so you can weigh the number against what it actually requires rather than the headline alone.

Yes. A smart meter, or export meter, capable of providing half-hourly export readings, so exported electricity can be measured rather than deemed.

Yes, on most tariffs. Of the 26 live tariffs we checked, only 4 make a battery a condition of the rate: Octopus Energy's Flux, Octopus Energy's Intelligent Flux, Good Energy's Solar Savings Exclusive, So Energy's So Bright Export. Every other live tariff on this page pays on solar export alone.

It depends on the tariff. Several of the strongest rates on this page are open to any household regardless of who supplies their electricity, including the standard Smart Export Guarantee most suppliers must offer; several others, mostly the higher rates, do require your electricity import to be with the same supplier. The conditions column in the table above states it for each one, since it changes tariff by tariff rather than following one rule.

Ofgem's own rules set no fixed payment interval: a smart meter, or export meter, capable of providing half-hourly export readings, so exported electricity can be measured rather than deemed. and each supplier reads that meter and pays on its own schedule. The Smart Export Guarantee (SEG) requires certain electricity suppliers ('SEG Licensees') to pay small-scale low-carbon generators for electricity they export to the National Grid. An electricity supplier with at least 150,000 domestic customers as at 31 December of the preceding year is a 'Mandatory SEG Licensee' for the following SEG year (1 April to 31 March), must offer at least one SEG export tariff, and cannot opt out. Suppliers below that threshold may register as Voluntary SEG Licensees. Suppliers must notify Ofgem of their SEG status by 14 February each year. Any SEG tariff rate offered must always be above zero pence per kWh -- Ofgem sets no minimum rate above that, and suppliers set their own rate, contract length and other terms.
