Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the effectiveness of current mechanisms supporting small-scale solar generation following the closure of the Feed-in Tariff scheme.

The Smart Export Guarantee (SEG) is a market-led mechanism that ensures small-scale solar generators receive payment for any electricity exported to the grid.

The Government keeps current market offerings under review to assess whether the market is continuing to deliver effective options. Ofgem also reports annually on the range and uptake
of SEG tariffs offered by suppliers.


The market offers a wide range of SEG tariffs, with registration numbers increasing to over 270,000 installations at the end of March 2025, compared with around 166,000 for the previous year.
