Best SEG & solar export rates.

Quick answer: The best flat rate you can get without buying anything is So Energy's So Bright Export at 20p/kWh — and despite what most comparison tables say, So Energy confirm you do not need to buy your electricity from them. Higher rates exist but come with strings: Good Energy pay 25p if you buy a battery through them, EDF 18p on kit bought from EDF. If you already have a battery, a time-of-use tariff like Octopus Flux can beat any flat rate at peak. The floor is around 1p, so switching off a bad tariff is often worth hundreds a year.

Rates below were checked on 19 August 2026. Rows marked “supplier website” come straight from the supplier’s own tariff pages that day; the rest are cross-checked comparison-site data with the source named. Suppliers change export rates often — always confirm on the supplier’s site before switching. We don’t take commission from any of them.

How to pick the right export tariff

The best rates come with strings attached. The 15p–25p headline tariffs almost all require you to buy your electricity from the same supplier, and the very highest are locked to systems that supplier installed. Compare the whole package: a 20p export rate paired with an expensive import tariff can cost you more overall than 12p export with a cheap import deal.

Battery owners should look at smart tariffs, not flat ones. Time-of-use tariffs pay most for evening-peak export. A battery lets you hold your solar power until then — that’s how peak rates near 29p become achievable in practice. Our smart tariff guide works through the maths, and the battery comparison covers the hardware.

Northern Ireland has no SEG. The scheme covers Great Britain only — NI exporters use supplier arrangements like Power NI’s export tariff instead. Our Northern Ireland solar guide explains the difference.
