New regulations on the Green Gas Support Scheme which came into effect on 4 June extend the scheme to 31 March 2028 (previously 30 November 2025).
The Green Gas Support Scheme (GGSS) has several mechanisms to manage budgets and ensure value for money, while maintaining investor confidence to encourage deployment. These were set out in the government response to our consultation.
New regulations on the Green Gas Support Scheme came into effect on 4 June 2024 to extend the scheme to 31 March 2028 (previously 30 November 2025).
These documents provide more detail for applicants and investors on:
- the budget caps
- the degression process
- the Annual Tariff Review
- the Green Gas Levy
See also details of the Green Gas Levy (GGL), which will fund the GGSS.
