• (a) an amount payable under these Regulations, or

• (b) a scheme supplier’s credit cover requirement for a quarter under regulation 41,

which does not exceed the amount specified by the Secretary of State (the “de minimis threshold”) for the scheme year in which the amount becomes payable or the quarter referred to in sub-paragraph (b) falls.

• (2) Where but for this paragraph an amount payable or a credit cover requirement under the following regulations would be a de minimis amount, no amount is payable or the credit cover requirement is £0 (as applicable)—

• (a) regulation 40(1),

• (b) regulation 41(1) or (2)(b),

• (c) regulation 44(1),

• (g) regulation 56(7),

• (h) regulation 56(10).

• (3) For the purposes of determining under paragraph (2) whether an amount otherwise payable under a regulation would be a de minimis amount—

• (a) the amount payable to a scheme supplier under regulation 44(1) is deemed to be the sum of the amounts payable to the supplier under regulation 44(1) and regulation 45(2)(a),

• (b) the amount payable to a supplier under regulation 45(2)(a) is deemed to be the sum of the amounts payable to the supplier under regulation 44(1) and regulation 45(2)(a),

• (c) the amount payable to a former scheme supplier under regulation 51(9) is deemed to be the sum of the amounts payable to the supplier under regulation 51(9) and 51(9A)(a),

• (d) the amount payable to a former scheme supplier under regulation 51(9A)(a) is deemed to be the sum of the amounts payable to the supplier under regulation 51(9) and 51(9A)(a).

• (4) Any sum which but for paragraph (2)(f) would have been paid by the Authority to a former scheme supplier must be treated by the Authority as if it had been paid to the Authority by the supplier in respect of a final quarterly levy payment.

• (5) Where paragraph (2) applies in respect of an amount otherwise payable or a scheme supplier’s credit cover requirement and but for this paragraph the Authority would be required to make a notification under the following regulations in respect of the amount or the credit cover requirement, the requirement to make a notification does not apply—

• (a) regulation 40(2),

• (b) except where regulation 42(5) applies, regulation 42(1),

• (c) regulation 49(2),

• (d) regulation 56(5)(b).

• (6) Where paragraph (5) applies, the Authority may make such alternative notification as it considers appropriate.

• (7) The Secretary of State must by notice publish the de minimis threshold for the scheme year beginning with 1st April 2024 and each subsequent scheme year.

• (8) The de minimis threshold for a scheme year must not be more than the amount calculated in accordance with paragraph (9) (the “de minimis maximum”).

• (9) The de minimis maximum for a scheme year is £200, adjusted by the percentage increase or decrease in the consumer prices index for the period beginning with 1st January 2024 and ending with 31st October immediately preceding the scheme year.

• (10) A notice under paragraph (7) must be published by—

• (a) in relation to the de minimis threshold for the scheme year beginning with 1st April 2024, the later of the date falling 14 days after the Green Gas Support Scheme (Amendment) Regulations 2023 come into force and 31st December 2023,

• (b) in relation to the de minimis threshold for the scheme year beginning with 1st April 2025 and each subsequent scheme year, 31st December in the preceding scheme year.

• (c) a declaration that the information provided by the applicant or participant is accurate to the best of the applicant’s or participant’s knowledge and belief.

• (3) Upon receiving an application under paragraph (1) the Authority must—

• (a) determine whether the heat pump meets the criteria for an eligible heat pump,

• (b) if satisfied that the heat pump does meet the criteria for an eligible heat pump, register that heat pump as an eligible heat pump, and

• (c) notify the applicant or participant (as appropriate), in writing, of the Authority’s determination.

• (4) Where the Authority determines that the heat pump does not meet the criteria to be registered as an eligible heat pump, it must provide reasons for the Authority’s determination.

• (6) The Authority may review a registration of an eligible heat pump, and where the Authority determines that a heat pump that is registered as an eligible heat pump—

• (a) did not meet the criteria for an eligible heat pump at the time of the Authority’s determination under paragraph (3), or

• (b) no longer meets the criteria for an eligible heat pump,

the Authority must remove the registration of that heat pump as an eligible heat pump.

• (7) Where the Authority makes a determination under paragraph (6), it must notify the participant in writing within 28 days of making the determination, and it must provide reasons for the Authority’s determination.

• “grant from public funds” means a grant made by a public authority or by any person distributing funds on behalf of a public authority, except for a grant that offers a discount on the unit price of electricity.
