Under the SEG, homeowners and businesses can be paid per kWh, by large energy suppliers, for the energy exported to the grid.
The price is be determined by each energy supplier and tend to vary between 0.1p and 5p per Kwh. Whilst the energy suppliers have to set the price of their SEG above 0 per kWh, the contract length is completely up to them.
Small energy suppliers (companies with less than 250,000 customers) don’t have to offer a SEG. However, should they decide to offer one, they would have to follow the same SEG rules.
