British Gas SEG Rate Drops From 15.1p To 8p: What The Changes Mean For Solar Export Revenue
The British Gas SEG scheme has been one of the most attractive export tariff options available to UK solar generators in recent years.
However, from 6 July 2026, British Gas is making significant changes to its Smart Export Guarantee (SEG) scheme, reducing export payments for larger solar installations.
For many commercial solar owners, farms, schools, warehouses, and industrial facilities, this change could have a substantial impact on annual export revenue and may prompt a review of existing solar tariff arrangements.
