What are the best SEG and export tariffs?
The best UK export tariffs pay around 15p per kWh or more, well above the minimum a supplier must offer. The right tariff depends on whether you have a battery and an electric vehicle, because the strongest deals often pair a high export rate with cheap overnight import for charging. Compare export rate, any tie-in to import tariffs, and payment frequency.
How to compare export tariffs
- Export rate per kWh: the headline number, but not the whole picture.
- Fixed vs variable: fixed gives certainty; variable can pay more at peak times.
- Bundled deals: some require you to also import from the same supplier.
- Battery and EV fit: the best value often comes from combining cheap night import with daytime export.
Maximising export income
If you have a battery, you can charge it cheaply overnight and export stored solar when rates are highest on a time-of-use export tariff. Without a battery, a simple high flat export rate is usually best. Either way, you are free to switch your export supplier independently of your import supplier.
