The Smart Export Guarantee is a support mechanism designed to ensure small-scale generators are paid for the renewable electricity they export to the grid. It has been in place since 1 January 2020.

If you live in England, Scotland or Wales, you could benefit from a Smart Export Guarantee (SEG) tariff.

There are no set or minimum tariffs for the SEG – the only requirement is that the tariff must be greater than zero at all times. In practice, this means that it is up to energy suppliers to decide what tariffs to offer their customers. They may choose to offer multiple tariffs or just one.

SEG tariffs can be fixed or variable. A fixed SEG tariff will pay a determined rate per kWh of electricity exported over the length of the contract. A variable SEG tariff will vary the price based on market demand, with the only requisite that prices never fall below zero.

Ofgem publishes a list of SEG licensees every year. You should contact the energy supplier directly for information on their available SEG tariffs.
