UK Energy Grant
Smart Export Guarantee (SEG)
Licensed energy suppliers must offer a tariff that pays you for every unit of surplus solar electricity you export to the National Grid — a guaranteed income stream for solar owners.
Overview
What is the SEG?
The Smart Export Guarantee (SEG) is administered by Ofgem and available to eligible properties in UK-wide. It is designed to help homeowners reduce the upfront cost of installing low-carbon energy systems and improvements — contributing to the UK's net-zero targets while lowering household energy bills.
This scheme supports installations including Solar PV, Micro-CHP, Wind Turbine.
Eligibility
