Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the average price per kilowatt that businesses receive from suppliers when selling power to the grid under the Smart Export Guarantee compared to domestic households.

It is a commercial decision for suppliers as to how they choose to set export tariffs, and whether to treat domestic and business customers differently for the purpose of tariffs offered under the Smart Export Guarantee (SEG). Most suppliers offer SEG tariffs that are available to both domestic and business customers, but some do provide distinct tariff offerings.

Details of the tariffs can be found in Ofgem’s SEG annual report. The latest report can be found at the SEG Smart Export Guarantee Annual Report - April 2024 to March 2025 | Ofgem
