Smart Export Guarantee rates compared
Export rates and the conditions attached to them. The highest rates usually need you to buy your electricity from that supplier, and some only apply if they installed your panels and battery, or only at certain hours.
We list a rate only when the source ties the figure clearly to one named tariff, and we re-read these pages every month. “Maximum” means the supplier says “up to”; ask what you would actually get.

How the scheme works
Mandatory SEG licensees have at least 150,000 domestic electricity customers.

Ofgem states that adding battery storage is possible where the export meter separately measures electricity from the eligible installation.
“as long as the export meter is still able to measure the amount of electricity generated/exported from the installation separately from any other source.”Source: ofgem.gov.uk (PDF, page 64), read 19 October 2026
SEG licensees must pay for stored electricity subsequently exported where it is guaranteed to come only from the SEG installation.
“SEG Licensees are obligated to make SEG payments when the electricity stored in co-located storage and subsequently exported can be guaranteed to only have come from the SEG installation (green export).”Source: ofgem.gov.uk (PDF, page 64), read 19 October 2026
Ofgem says that if your export meter also records electricity from another source, such as grid power stored in a battery, and cannot tell how much, the supplier does not have to make SEG payments.

Why it matters for a battery
Solar you store instead of exporting earns nothing at the export rate; it saves you the import rate later, minus what is lost in charging. At 26p import and 90% round-trip efficiency, a stored kWh saves about 23p. Against a 4p export rate that is a gain of about 19p; against 15p, about 8p. So the higher your export rate, the less a battery adds. Put the rate you can actually get into the calculator.
