Explanatory note
(This note is not part of the Regulations)
These Regulations, which apply in Great Britain, amend the Green Gas Support Scheme Regulations 2021 (S.I. 2021/1335) (“the 2021 Regulations”), which established the Green Gas Support Scheme (“the GGSS”). The GGSS is a renewable heat incentive scheme designed to support the production of biomethane by anaerobic digestion for injection into the gas grid.
Regulation 3 makes amendments to regulation 4 of the 2021 Regulations to extend the date by which equipment used to produce biomethane for injection must be commissioned to 31 March 2030 for applicants who apply to the GGSS on or after 16 October 2026. Applicants who made an application on or after 10 December 2025, but before 16 October 2026, can make a request to the Authority to amend their tariff guarantee that substitutes a later date, that is no later than 31 March 2030, by which the injection of biomethane must commence.
Regulations 4 and 5 make amendments to regulations 6 and 7 of the 2021 Regulations to reflect the extended date by which equipment used to produce biomethane for injection must be commissioned.
Regulation 6 corrects a drafting error in regulation 8A of the 2021 Regulations to clarify that exemptions from deductions for heat from, and deductions in respect of electricity supplied to, eligible heat pumps cannot be applied before the Authority has received a complete application under regulation 8A(1).
Regulations 7, 8 and 10 make amendments to regulations 10, 13 and 28 of the 2021 Regulations respectively, to align the periods to which they relate with scheme years instead of payment years.
Regulation 9 makes amendments to regulation 21 of the 2021 Regulations so that, where a tariff start date falls after 31 March 2028, periodic support payments are only payable until 31 March 2043.
Regulation 11 is a saving and transitional provision. It preserves the treatment of payment years beginning before 1 April 2027 and provides for how they are to be accounted for in relation to the reconciliation of payments process following the change to the relevant time period.
A full impact assessment has not been produced for this instrument as no significant impact on the private, voluntary or public sectors is foreseen.
