Powers of the Department when considering an authorisation application 24 The Department may— a arrange for a site inspection to be carried out by the Department or its authorised agent; b request that information about the meters be provided from a certified installer who was responsible for, or checked, the installation of the meters; c if information is provided by the person making the authorisation application, request evidence that the accuracy of the information is verified by the certified installer who was responsible for, or checked, the installation of the meters. Authorisation 25 1 Where paragraph (2) applies, the Department must— a give authorisation for the metering arrangement; and b notify the applicant that the authorisation application has been successful. 2 This paragraph applies if the Department is satisfied that— a all eligible meters located in accordance with the metering arrangement are positioned in accordance with the relevant paragraph of regulations 15 or 16; b the requirements set out in paragraph (3) are met; and c the requirements set out in paragraphs (4) to (6) are met as applicable. 3 The requirements set out in this paragraph are that the location and type of eligible meters identified in the metering arrangement will or would if the plant (“plant A”) were given accreditation, enable sufficient information to be gathered for the Department to calculate plant A's eligible metered heat in a way that will not result in RHI payments which are materially greater than if eligible meters were installed in accordance with regulation 15(2) (for biomass plants), or 16(2) (for heat pumps). 4 The requirements set out in this paragraph are that, if eligible meters are positioned in accordance with paragraph (3) or (4) of regulation 15, or paragraph (3) or (4) of regulation 16, the heat output from plant A cannot be metered separately from the heat output from another plant (“plant B”). 5 The requirements set out in this paragraph are that, if eligible meters are installed in accordance with paragraph (4) of regulation 15, or paragraph (4) of regulation 16— a eligible meters cannot be installed to separately record the heat output from plant B; and b other measurements recorded by eligible meters can be used to calculate the heat output from plant A. 6 The requirements set out in this paragraph are that, if eligible meters are installed in accordance with paragraph (5) of regulation 16, plant A is a heat pump which is capable of providing heating as well as cooling. PART 5 RHI PAYMENTS Duty to make RHI payments 26 1 Subject to Parts 8 and 10, the Department must make payments, referred to in these Regulations as “ RHI payments ”, to a participant (“P”) in respect of the heat generated by P's accredited domestic plant. 2 RHI payments accrue for seven years from the tariff start date. 3 The Department— a must calculate the amount of RHI payments in accordance with regulation 27, 28, 29 or 30 and make RHI payments in arrears; b may decide on the frequency of any RHI payments. 4 The total RHI payments made to a participant under paragraph (1) will not exceed £2500 in any given year. 5 Where— a the Department does not have all of the data it requires to calculate an RHI payment; and b is unable to obtain any missing data under regulation 39(4), the Department may estimate that data in order to make that calculation. Calculation of deemed annual heat generation 27 1 The amount of heat in kWh which an accredited domestic plant is deemed to generate every 12 months (the “deemed annual heat generation”) is calculated in accordance with this regulation. 2 If the accredited domestic plant is a biomass plant which provides space heating (but not heating for domestic hot water) to the RHI property, the deemed annual heat generation is the heat demand for space heating specified in the relevant EPC for that property. 3 If the accredited domestic plant is a biomass plant which provides both space heating and domestic hot water heating to the RHI property, the deemed annual heat generation is the heat demand for space heating and water heating specified in the relevant EPC for that property. 4 If the accredited domestic plant is a heat pump which provides space heating (but not heating for domestic hot water) to the RHI property, the deemed annual heat generation is calculated in accordance with the following formula— A × ( 1 − 1 B ) where— A is the heat demand for space heating specified in the relevant EPC for that property; B is the seasonal performance factor for the heat pump. 5 If the accredited domestic plant is a heat pump which provides both space heating and domestic hot water heating to the RHI property, the deemed annual heat generation is calculated in accordance with the following formula— A × ( 1 − 1 B ) where— A is the heat demand for space heating and water heating specified in the relevant EPC for that property; B is the seasonal performance factor for the heat pump. Calculation of RHI payments for biomass plants and heat pumps 28 The RHI payment for an accredited domestic plant that is a biomass plant or a heat pump is calculated using the following formula, that is to say— deemed annual heat generation x relevant tariff = RHI payment for any given year. Calculation of RHI payments for solar thermal 29 The RHI payment for an accredited domestic plant that is a solar thermal plant shall be calculated using the following formula, that is to say— estimated annual generation x Relevant Tariff = RHI payment for any given year, where the estimated annual generation is the figure recorded as such in the MCS Certificate for the plant in question. Calculation of RHI payments where heat generated by a plant must be metered 30 1 The RHI payment for an accredited domestic plant that is metered under regulation 13 shall be calculated using the following formula, that is to say— metered annual heat output x relevant tariff = RHI payment for any given year. 2 Notwithstanding paragraph (1), eligible metered heat is the heat in kWh recorded by eligible meters positioned in accordance with regulations 15 or 16 generated by— a the accredited domestic plant; or b the accredited domestic plant and any additional plants if the heat generated by the accredited domestic plant is recorded together with the heat generated by such additional plants. 3 RHI payments in any year shall not in any case exceed the amount which would be paid in accordance with regulation 27 or regulation 28 if a meter had not been installed in relation to that accredited domestic plant Payment of upfront support 31 1 In addition to any RHI payment made by the Department under regulation 27 or regulation 28, subject to paragraph (2), the Department shall make an upfront payment in the quantum specified in column (2) of Table 2 of Schedule 4 opposite the reference to the plant in column (1). 2 Upfront payments shall be made only in respect of accredited domestic plant commissioned on or after 1st September 2010 which have not received the support of a RHPP grant. 3 Upfront payments shall not be made in respect of replacement plants installed in accordance with regulation 43. PART 6 CALCULATION OF TARIFFS Duty to calculate and publish tariffs 32 1 The Department must calculate in accordance with this Part and publish on its website, by the dates specified in paragraphs (2) and (3), tables specifying in relation to each tariff category— a the initial tariffs for accredited domestic plants with a tariff start date in the tariff period immediately following the date on which the table is published; and b the subsequent tariffs for accredited domestic plants for the financial year which commences on or after the date on which the table is published. 2 The tables of initial and subsequent tariffs must be published by— a 1st April 2015, but only where the relevant date is earlier than that date; and b On 1st April of each subsequent calendar year. Calculation of initial tariffs 33 1 The initial tariff for an accredited domestic plant is calculated in accordance with this regulation. 2 For the period beginning with the commencement of these Regulations and ending with 31st March 2015, the initial tariff for each plant is the tariff specified in column (2) of Table 1 of Schedule 4 opposite the reference to the plant in column (1). 3 For each subsequent year commencing with 1st April and ending with the following 31st March, the initial tariff for each plant is the tariff applicable to it on the immediately preceding 31st March in the previous year adjusted by the percentage increase or decrease (as applicable) in the retail prices index for the previous calendar year (the resulting figure being stated to two decimal places and rounded to the nearest hundredth of a penny, with any two hundredth of a penny being rounded upwards). Calculation of subsequent tariffs 34 1 The subsequent tariff for an accredited domestic plant is calculated in accordance with this regulation. 2 For each year commencing with 1st April and ending with the following 31st March, the subsequent tariff for each plant is the tariff applicable to it on the immediately preceding 31st March in the previous year adjusted by the percentage increase or decrease (as applicable) in the retail prices index for the previous calendar year (the resulting figure being stated to two decimal places and rounded to the nearest hundredth of a penny, with any two hundredth of a penny being rounded upwards). PART 7 ONGOING OBLIGATIONS FOR PARTICIPANTS Ongoing obligations: general 35 A participant (“P”) must comply with the following ongoing obligations, as applicable— a if the accredited domestic plant is a biomass boiler, upon a request by the Department P must provide to the Department evidence as to the type of fuel purchased and used in that plant for any period specified in the request during which P was a participant; b P must not receive any grant from public funds, other than a RHPP grant, for any of the costs of the purchase or installation of the accredited domestic plant other than any grant which was notified to the Department when the accreditation application was made; c P must ensure that the accredited domestic plant continues to meet the eligibility criteria; d P must comply with any condition attached to P's accreditation; e P must keep the accredited domestic plant in good working order; f if P is not the owner of the RHI property, P must provide a copy of any notification under regulation 36(1)(i) or 36(1)(j) to the owner or owners of that property; g P must repay any overpayment in accordance with any notice served under regulation 51; h P must not move the accredited domestic plant to a new location; i P must comply with such other administrative requirements that the Department may specify in relation to the effective administration of the domestic RHI scheme; j on receipt of a request for access under regulation 47 or regulation 54(3)(b), P must— i allow the Department or the Department's authorised agent, as applicable, access to the RHI property to carry out any of the activities described in those regulations; and ii offer reasonable cooperation to that person; k if P does not live in the RHI property P must have, at all times, agreement from all occupants of the property that those occupants will: i allow the Department or the Department's authorised agent reasonable access in the event of a request under regulation 47 or regulation 54(3)(b); ii cooperate with a decision by the Department to install a meter under regulation 45 or remove it under regulation 46; and iii cooperate with any request for assistance made under regulations 54(3)(b) or 54(3)(c); l P must not seek accreditation under the Renewable Heat Incentive Scheme Regulations (Northern Ireland) 2012 for an accredited domestic plant, or any other plant which provides heat to the same RHI property as an accredited domestic plant; and m P must cooperate with: i a decision by the Department to install a meter under regulation 45 or remove it under regulation 46; and ii any request for assistance made under regulations 54(3)(b) or 54(3)(c).

Ongoing obligations: annual declarations 37 A participant (“P”) must submit a declaration each year to the Department, at such time and in such form as the Department may request, confirming— a that P continues to own the accredited domestic plant; b that, to the best of P's knowledge and belief, no owner or previous owner of the accredited domestic plant has received— i any grant from public funds for the cost of the purchase or installation of the accredited domestic plant other than any grant which was notified to the Department before the accreditation application was determined; or ii funding from any other source (other than under a loan) which reimbursed all of the costs incurred by P, any other owner or any previous owner for the cost of the purchase or installation of the accredited domestic plant; c that the accredited domestic plant is in good working order and has not been replaced with another plant, unless P has notified the Department of the installation of that plant under regulation 36(1); d the number of days on which the RHI property was occupied in the 12 month period ending on the date the declaration is given and the number of days on which P expects the property to be occupied in the next 12 months; e if P does not live in the RHI property, that all occupants of the property have agreed to permit access to the property by the Department or the Department's authorised agent for the purposes of carrying out any function under these Regulations; and f where the Department has provided a metering statement for the accredited domestic plant, that each eligible meter which is required under that statement is in good working order. Ongoing obligations: emissions from biomass 38 Where an accredited domestic plant is a biomass plant to which an RHI emission certificate applies, a participant must— a use fuel of a type specified in the RHI emission certificate; b use fuel with a moisture content which is no greater than the maximum moisture content specified in the RHI emission certificate; and c operate the plant in accordance with the manufacturer's instructions for that plant in relation to the control of emissions of Particulate Matter (PM) and Nitrogen Oxides (NOx). Ongoing obligations: metering 39 1 This regulation applies to a participant (“P”) where the Department has provided a metering statement for an accredited domestic plant. 2 P must ensure that— a the heat generated by the plant is metered from the date on which the Department provides the metering statement until the tariff end date; b eligible meters are positioned in accordance with the paragraph of regulation 15 or 16 specified in the metering statement; and c if the Department has authorised a metering arrangement, each eligible meter identified in that arrangement is located as identified in that arrangement. 3 P must keep each eligible meter which is required under a metering statement for the accredited domestic plant— a in good working order; and b positioned in accordance with the paragraph of regulation 15 or 16 specified in the metering statement. 4 The Department may request that P provide meter readings and other data from all eligible meters required by these Regulations. 5 Any meter readings or other data requested under paragraph (4) must be provided by P— a in such form as the Department may request; and b by the date (if any) specified by the Department or at such regular intervals as the Department may request to enable it to discharge its functions under these Regulations. 6 Nothing in this regulation prevents the Department from accepting further data from a participant, if the Department considers it appropriate to do so. Ongoing obligations: provision of information 40 1 A participant (“P”) must provide to the Department on request any information which P holds and which the Department requires in order to discharge its functions under these Regulations. 2 P must retain a copy of— a any information relied on when making any accreditation application or, if P did not make that application, given to P by the person who made the application; and b any other evidence which verifies that the accredited domestic plant meets the eligibility criteria and that P is continuing to comply with the ongoing obligations, whether or not copies of that documentation have been supplied to the Department. 3 P must comply with any request for information under paragraph (1) within 28 days of the request or such later date as the Department may specify. PART 8 CHANGES AFFECTING ACCREDITED DOMESTIC PLANTS Review of accreditation following notification of a change in circumstances 41 1 This regulation applies where the Department receives a notification under regulation 36 and regulations 43 and 44 do not apply. 2 Where this regulation applies, subject to regulation 42(2)(b), no RHI payment may be made for the accredited domestic plant until the requirements set out in paragraph (4) are met. 3 On receipt of the notification, the Department may— a require the participant to provide such of the information specified in Schedule 3 and any declarations as the Department considers necessary for the proper administration of the domestic RHI scheme; and b review the accreditation of the accredited domestic plant to ensure that it continues to meet the eligibility criteria. 4 The requirements referred to in paragraph (2) are that the Department has notified the participant that— a it is satisfied that the matters to which the notification relates are such that it is unnecessary to review the accreditation of the plant; or b it has carried out a review and is satisfied that the plant should continue to be an accredited domestic plant. 5 Following a notification under paragraph (4) the Department must resume payment of RHI payments in accordance with these Regulations. Changes affecting whether accredited domestic plants must be metered 42 1 This regulation applies where— a a metering statement has not been provided for an accredited domestic plant; b the Department has reviewed the accreditation of an accredited domestic plant under Regulation 41 or has carried out an investigation under Part 10; and c the Department considers that, were an accreditation application made in respect of the accredited domestic plant on the date on which the Department concluded its review or investigation, regulation 13 would require the heat generated by the plant to be metered. 2 Where this regulation applies— a the heat generated by the plant must be metered; and b no RHI payment may be made for the accredited domestic plant until the Department has provided the participant with a metering statement under paragraph (5). 3 The Department may require the participant to provide a statement from a certified installer who was responsible for, or checked, the installation of any meters installed in respect of the plant— a confirming that each eligible meter is installed in accordance with the metering requirements; and b stating whether the eligible meters are installed in accordance with paragraph (2), (3) or (4) of regulation 15, or paragraph (2), (3), (4) or (5) of regulation 16. 4 If eligible meters are positioned in accordance with paragraph (3) or (4) of regulation 15, or paragraph (3), (4) or (5) of regulation 16, the participant must make an authorisation application. 5 The Department must provide the participant with a metering statement if it— a is satisfied that the requirements in regulation 14 are met; and b has given authorisation, if applicable. 6 RHI payments for the accredited domestic plant are calculated in accordance with— a regulations 27 and 28 for the period commencing on the tariff start date and ending on the date on which the Department received the notification under regulation 36 or commenced its investigation under Part 10; and b regulation 30 for the period commencing on the date on which the Department provides the participant with a metering statement and ending on the tariff end date. 7 No RHI payments are payable for the period commencing on the day after the date on which the Department received the notification under regulation 36 and ending on the day before the date on which the Department provides the participant with a metering statement. Replacement plants 43 Where a replacement plant is installed— a an accreditation application for that plant may be made by the owner of the replacement plant if that person is a participant in relation to the original plant; and b no RHI payments are payable for the period commencing on the date on which the original plant ceased to provide heat to the property and ending on the day before the date on which the Department received the accreditation application for the replacement plant. Changes in ownership of accredited domestic plants 44 1 This regulation applies where a participant transfers ownership of all or part of an accredited domestic plant to another person (“the new owner”). 2 Once the Department becomes aware of the transfer of ownership, no RHI payment may be made until— a the new owner has notified the Department of the change in ownership and has confirmed, if the plant is owned by more than one person, that they have the authority form all owners to be the new participant; and b the Department has taken the steps set out in paragraph (5). 3 On receipt of a notification under paragraph (2), the Department may— a require the new owner to provide such of the information specified in Schedule 3 and any declarations as the Department considers necessary for the proper administration of the domestic RHI scheme; and b review the accreditation of the accredited domestic plant to ensure that it continues to meet the eligibility criteria. 4 In carrying out the review referred to in paragraph (3)(b) the Department may, in order to satisfy itself that the accredited domestic plant continues to meet the eligibility criteria, take any of the steps set out in regulation 18. 5 Where the Department is satisfied that the accredited domestic plant continues to meet the eligibility criteria or has decided not to carry out a review it must— a update the central register; and b send the new owner a statement of eligibility setting out the information specified in regulation 21(1)(e). 6 If the Department becomes aware of the transfer of ownership and, within a period of 12 months from the transfer of ownership of the accredited domestic plant taking effect— a no notification is made by the new owner in accordance with paragraph (2)(a); or b any information required under paragraph (3)(a) is not provided to the Department, the plant shall on the expiry of that period cease to be an accredited domestic plant and accordingly no further RHI payments will be paid for the plant. 7 The period specified in paragraph (6) may be extended by the Department where the Department considers it is just and equitable to do so. 8 Subject to paragraph (9) and Part 10, RHI payments are calculated from the date of completion of the steps set out in paragraph (5) for the remainder of the tariff lifetime of that accredited domestic plant. 9 Where a transfer of ownership of all or part of an accredited domestic plant takes place and that accredited domestic plant is then owned by more than one person, the Department may require any person claiming to have the authority from all owners to be the new participant to provide to the Department, in such manner and form as the Department may request, evidence of this authority. PART 9 METERING FOR MONITORING PURPOSES BY THE DEPARTMENT Installation of a meter at the Department's request 45 The Department may install an eligible meter in order to collect data, assess performance and monitor progress against renewable heat targets under regulation 13(7).
