Rejection of accreditation applications 22 1 The Authority may reject an accreditation application if— a the Authority is not satisfied that the accreditation application has been properly made in accordance with regulation 17 ; b the Authority is not satisfied that the plant meets the eligibility criteria; c the Authority has reason to believe that one or more of the applicable ongoing obligations will not be complied with; or d subject to paragraph (2), information requested by the Authority is not provided within the time limit specified in regulation 19 . 2 The Authority must not reject an accreditation application on the basis that information has not been provided in accordance with regulation 19(c) if— a the applicant contacted the Authority before the 28 day period expired— i stating that the information sought is not yet available; ii stating that the information cannot be provided; or iii providing alternative information; and b fewer than three months have passed since the date of the first notice in which the Authority requested the information. 3 Where the Authority decides to reject an accreditation application it must notify the applicant that the application has been rejected, giving reasons. PART 4 Authorisation of metering arrangements Authorisation applications 23 1 Where the owner of a plant (“plant A”) is required by regulation 17(2)(e) or 46(4) to make an authorisation application, that application must be made in accordance with this regulation. 2 An authorisation application in respect of plant A must not be made before an accreditation application is made for plant A. 3 A person who makes an authorisation application must provide to the Authority— a details of the metering arrangement; b if eligible meters are positioned in accordance with paragraph (3) or (4) of regulation 15 or paragraph (3) or (4) of regulation 16 , evidence from the certified installer who was responsible for, or checked, the installation of the meters explaining why the heat output from plant A cannot be metered separately from the heat output from another plant (“plant B”); c if eligible meters are positioned in accordance with paragraph (4) of regulation 15 or paragraph (4) of regulation 16 , evidence from the certified installer who was responsible for, or checked, the installation of the meters explaining why the heat output from plant B cannot be metered separately from the heat output from plant A; d if eligible meters are positioned in accordance with paragraph (5) of regulation 16 , evidence that plant A is a heat pump which is capable of providing heating as well as cooling; and e any other information which the Authority may request in order to enable it to consider the authorisation application. Powers of the Authority when considering an authorisation application 24 The Authority may— a arrange for a site inspection to be carried out by the Authority 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 Authority 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 Authority is satisfied that— a all eligible meters located in accordance with the metering arrangement are positioned in accordance with the relevant paragraph of regulation 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 Authority 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 record separately 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 Authority 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 Authority— a must calculate the amount of RHI payments in accordance with regulation 27 or 28 and make RHI payments in arrears; b may decide on the frequency of any RHI payments. 4 Where— a the Authority 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 43(4) , the Authority may estimate that data in order to make that calculation. Calculation of RHI payments where metering is not required 27 Subject to regulation 48(6)(b), where the Authority has not provided a metering statement for an accredited domestic plant, the RHI payment for that plant for any quarterly period is calculated in accordance with the following formula— ( A × B 4 ) − C where— A is the applicable initial tariff or subsequent tariff for the accredited domestic plant; B is the deemed annual heat generation for the plant; and C is the grant funding deduction for the accredited domestic plant for the quarterly period. Calculation of RHI payments where heat generated by a plant must be metered 28 1 Where the Authority has provided a metering statement for an accredited domestic plant, the RHI payment for that plant for any quarterly period is calculated in accordance with this regulation. 2 Subject to paragraph (3), the RHI payment for a quarterly period is R, where R is calculated in accordance with the following formula— ( A × B ) − C + D where— A is the applicable initial tariff or subsequent tariff for the accredited domestic plant; B is— subject to paragraph (ii), the eligible metered heat for the plant for the quarterly period; or 0 if the eligible metered heat is less than 0; C is the grant funding deduction for the plant for the quarterly period; and D is— 0 if the quarterly period commences on the tariff start date; 0 if the quarterly period commences on any subsequent date and PR is 0 or greater; or PR if the quarterly period commences on any subsequent date and PR is less than 0. 3 Where R is a figure which is less than 0, the RHI payment for the quarterly period is 0. 4 Where in any quarterly period, R is a figure which is 0 or higher and the sum of that figure and AP is greater than MaxP, the RHI payment for the quarterly period is calculated in accordance with the following formula— M a x P − A P 5 In this regulation— “AP” is the sum of all RHI payments payable for heat generated by the accredited domestic plant for the applicable period other than the RHI payment for that quarterly period; “applicable period” means— the 12 month period commencing on the tariff start date or the anniversary of the tariff start date and which includes the quarterly period; or the period commencing on the tariff start date or the anniversary of the tariff start date for which the Authority has received four quarterly meter readings and which includes the quarterly period; and “MaxP” means the figure calculated in accordance with the following formula— ( E × F ) − G where— E is the applicable initial tariff or subsequent tariff for the accredited domestic plant; F is the deemed annual heat generation for the plant for the applicable period; and G is the grant funding deduction for the plant for the quarterly period, multiplied by 4; and “PR” is the value of R for the accredited domestic plant for the quarterly period immediately preceding the period for which RHI payments are being calculated. Calculation of deemed annual heat generation 29 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. 6 If the accredited domestic plant is a solar thermal plant and its first commissioning date is on or after the relevant date, its deemed annual heat generation is the total heat generated by that plant on an annual basis calculated in accordance with version 1.1 of the document entitled “Microgeneration Installation Standard: MCS 024 Solar Domestic Hot Water Energy Calculation” published on 16th December 2013 . 7 If the accredited domestic plant is a solar thermal plant and its first commissioning date is earlier than the relevant date, the deemed annual heat generation is the total heat which the Authority estimates, at the time it gives accreditation, that the accredited domestic plant will generate on an annual basis, having regard to any relevant information about the accredited domestic plant on the MCS register. Calculation of eligible metered heat generated by biomass plants 30 1 The eligible metered heat in kWh for an accredited domestic plant which is a biomass plant for any quarterly period is calculated in accordance with the following formula— A × ( B − C − D − E ) where— A is calculated in accordance with paragraph (2); B is calculated in accordance with paragraph (3); C is calculated in accordance with paragraph (5); D is calculated in accordance with paragraph (7); and E is calculated in accordance with paragraph (8). 2 A is— a 1 if the accredited domestic plant is a biomass boiler; or b 1.2 if the accredited domestic plant is a biomass stove. 3 Subject to paragraph (4), B is the heat in kWh recorded by eligible meters positioned in accordance with regulation 15 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. 4 Where any heat referred to in paragraph (3) is recorded at the point where it leaves a domestic hot water cylinder, the heat recorded at that point is multiplied by 1.43 before being included (with the heat recorded at any other point) in B. 5 C is— a subject to paragraph (6), the heat in kWh generated by any additional plants included in B if the relevant metering statement specifies that eligible meters must be positioned in accordance with regulation 15 (3); or b 0 in any other case. 6 Where any heat generated by any additional plants included in B is generated by an air source heat pump for the purposes of defrosting, all heat generated by that air source heat pump is multiplied by 0.97 before being included in C. 7 D is— a the electricity consumption in kWh by any additional plants if the relevant metering statement specifies that eligible meters must be positioned in accordance with regulation 15 (4); or b 0 in any other case. 8 E is— a if B includes heat generated by any additional plants which use a fuel when generating heat, the energy content of that fuel in kWh if the relevant metering statement specifies that eligible meters must be positioned in accordance with regulation 15 (4); or b 0 in any other case. 9 In this regulation, “relevant metering statement” means the metering statement for the accredited domestic plant. Calculation of eligible metered heat generated by heat pumps 31 1 Subject to paragraph (10), the eligible metered heat in kWh for an accredited domestic plant which is a heat pump for any quarterly period is calculated in accordance with the following formula— A × ( B − C − D ) − E where— A is calculated in accordance with paragraph (2); B is calculated in accordance with paragraph (3); C is calculated in accordance with paragraph (5); D is calculated in accordance with paragraph (7); and E is calculated in accordance with paragraph (8). 2 A is— a 0.97 if any of the heat referred to in paragraph (3) is generated by an accredited domestic plant which is an air source heat pump for the purposes of defrosting; or b 1 in any other case. 3 Subject to paragraph (4), B is the heat in kWh recorded by eligible meters positioned in accordance with regulation 16 generated by— a the components of the accredited domestic plant specified in the metering statement as being included in this calculation; or b the components referred to in sub-paragraph (a) and any additional plants if the heat generated by the accredited domestic plant is recorded together with the heat generated by such additional plants. 4 Where any of the heat referred to in paragraph (3) is recorded at the point where it leaves a domestic hot water cylinder, the heat recorded at that point is multiplied by 1.43 before being included (with the heat recorded at any other point) in B. 5 C is— a subject to paragraph (6), the heat in kWh generated by any additional plants included in B if the relevant metering statement specifies that eligible meters must be installed in accordance with regulation 16 (3), or if it specifies that eligible meters must be installed in accordance with regulation 16 (5) and the authorised metering arrangement provides for eligible meters to be located to record such heat; or b 0 in any other case. 6 Where any heat generated by any additional plants included in B is generated by an air source heat pump for the purposes of defrosting, all heat generated by that air source heat pump is multiplied by 0.97 before being included in C. 7 D is— a the energy content in kWh of any fuel which is used by the accredited domestic plant or any additional plants when generating the heat included in B if the relevant metering statement specifies that eligible meters must be installed in accordance with— i regulation 16 (4); or ii regulation 16 (5) and the authorised metering arrangement provides for eligible meters to be located to record such relevant energy consumption; or b 0 in any other case. 8 E is— a subject to paragraph (9), the electricity consumption in kWh by the accredited domestic plant and any additional plants used to generate the heat referred to in paragraph (3) if the relevant metering statement specifies that eligible meters must be installed in accordance with— i regulation 16 (2), (3) or (4); or ii regulation 16 (5) and the authorised metering arrangement provides for eligible meters to be located to record such relevant energy consumption; or b 0 in any other case. 9 Any electricity consumed when providing cooling is excluded from the electricity consumption referred to in paragraph (8)(a) before that consumption is included in E if— a the relevant metering statement states that eligible meters must be installed in accordance with regulation 16 (5); and b the authorised metering arrangement provides for eligible meters to be located to record— i electricity consumption by the accredited domestic plant while the plant is providing cooling to the RHI property separately from any other electricity consumption; or ii sufficient information about the accredited domestic plant to enable the electricity consumption when providing cooling to be determined. 10 Where the plant is a ground source heat pump, its eligible metered heat is the heat extracted from the ground (including water in the ground), surface water or both if— a the relevant metering statement states that eligible meters must be installed in accordance with regulation 16 (5); and b the authorised metering arrangement provides for eligible meters to be located to record such heat. 11 In this regulation— “relevant energy consumption” has the same meaning as in regulation 16 ; and “relevant metering statement” means the metering statement for the accredited domestic plant. Calculation of grant funding deduction 32 1 The grant funding deduction for an accredited domestic plant for any quarterly period is— a if none of the plant’s purchase or installation costs are funded by a grant from public funds, 0; b if some or all of the plant’s purchase or installation costs are funded by a grant from public funds, calculated in accordance with the following formula— A 28 where A is calculated in accordance with paragraph (2). 2 For the purposes of paragraph (1)(b), A is— a for the quarterly period commencing on the tariff start date, the figure that the Authority believes represents the total value of any grants from public funds which were received by the participant or any other owner, or former owner, of the accredited domestic plant for the costs of the purchase or installation of the accredited domestic plant; b for any subsequent quarterly period that— i does not include 1st April of any calendar year, the value of A in the previous quarterly period; or ii includes 1st April of any calendar year, the value of A in the previous quarterly period adjusted by the percentage increase or decrease in the retail prices index for the calendar year ending on 31st December immediately preceding that 1st April (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 6 Calculation of tariffs and cost control Duty to calculate and publish tariffs 33 1 The Authority 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 tariffs must be published by 15th September 2014 and 15th December 2014, and in each subsequent calendar year by 15th March, 15th June, 15th September and 15th December. 3 The tables of subsequent tariffs must be published by— a 1st April 2014, but only where the relevant date is earlier than that date; and b 1st April 2015 and 1st April of each subsequent calendar year. Calculation of initial tariffs 34 1 The initial tariff for an accredited domestic plant is calculated in accordance with this regulation. 2 Where the first commissioning date for the accredited domestic plant is earlier than the relevant date or its tariff start date is earlier than 1st October 2014, the initial tariff is the tariff for the plant’s tariff category set out in Schedule 5. 3 In any other case, the initial tariff is calculated in accordance with the following formula— A × B where— A is calculated in accordance with regulation 35 ; and B is calculated in accordance with regulation 36 . Calculation of initial tariffs: calculation of A 35 1 This regulation provides for the calculation of A for the purposes of regulation 34 (3)(a). 2 If the accredited domestic plant’s tariff start date is in a tariff period commencing on— a 1st October 2014, A is the tariff for the tariff category for the accredited domestic plant (“the relevant tariff category”) set out in Schedule 5; b any date other than 1st October 2014 or 1st April of any year, A is the initial tariff for plants in the relevant tariff category with a tariff start date in the immediately preceding tariff period, published by the Authority under regulation 33(1)(a) (“C”); or c 1st April (other than 1st April 2014), A is C multiplied by the percentage increase or decrease in the retail prices index for the immediately preceding 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 initial tariffs: calculation of B 36 1 This regulation provides for the calculation of B for the purposes of regulation 34 (3)(b). 2 B is 1 if— a the expenditure threshold is not exceeded on the relevant assessment date; b the previous value of B is 0.9 and neither the super expenditure threshold nor the growth threshold is exceeded on the relevant assessment date; or c the previous value of B is 0.8 and the growth threshold is not exceeded on the relevant assessment date. 3 B is 0.9 if— a the previous value of B is 1 and the expenditure threshold is exceeded on the relevant assessment date but the super expenditure threshold is not exceeded on that date; b the previous value of B is 0.9 and on the relevant assessment date— i the expenditure threshold is exceeded but the super expenditure threshold is not exceeded; and ii the growth threshold is exceeded; or c the previous value of B is 0.8 and on the relevant assessment date— i the expenditure threshold is exceeded; and ii the growth threshold is exceeded but the super growth threshold is not exceeded. 4 B is 0.8 if— a the previous value of B is 1 or 0.9 and the super expenditure threshold is exceeded on the relevant assessment date; or b the previous value of B is 0.8 and both the super expenditure threshold and the super growth threshold are exceeded on the relevant assessment date. 5 In this regulation— a the expenditure threshold is exceeded on an assessment date if the forecast for expenditure for the relevant tariff category in relation to that date exceeds the figure specified for that tariff category and assessment date in the second column of the table in the relevant Part of Schedule 6; b the growth threshold is exceeded on an assessment date if the increase in expenditure forecast for the relevant tariff category in relation to that date exceeds the figure specified in relation to that tariff category and date in the third column of the table in the relevant Part of Schedule 6; c the super expenditure threshold is exceeded on an assessment date if the forecast for expenditure for the relevant tariff category in relation to that date exceeds the figure specified in relation to that date in the fourth column of the table in the relevant Part of Schedule 6; d the super growth threshold is exceeded on an assessment date if the increase in expenditure forecast for the relevant tariff category in relation to that date exceeds the figure specified in relation to that tariff category and date in the fifth column of the table in the relevant Part of Schedule 6; e the previous value of B is, if the accredited domestic plant’s tariff start date is in the tariff period commencing— i on 1st October 2014, 1; or ii after 1st October 2014, the value of B when the Authority calculated the initial tariffs for plants in the relevant tariff category with a tariff start date in the immediately preceding tariff period. 6 For the purposes of this regulation— “relevant assessment date” means the assessment date immediately preceding the commencement of the relevant tariff period; “relevant tariff category” means the tariff category for the accredited domestic plant; and “relevant tariff period” means the tariff period that the tariff start date for the accredited domestic plant is in. Calculation of subsequent tariffs 37 1 The subsequent tariff for an accredited domestic plant is calculated in accordance with this regulation. 2 For the financial year (“ FY1 ”) commencing immediately following the end of the initial tariff period, the subsequent tariff is, if FY1— a commences on 1st April 2014, the tariff set out in Schedule 5; b does not commence on 1st April 2014, calculated in accordance with the following formula— A × C 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. 3 For each financial year after FY1, the subsequent tariff is calculated in accordance with the following formula— B × C 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. 4 In paragraphs (2) and (3)— a A is the initial tariff for the accredited domestic plant; b B is the subsequent tariff for the accredited domestic plant in the immediately preceding financial year; and c C is the percentage increase or decrease in the retail prices index for the calendar year ending on 31st December immediately preceding the commencement of the financial year for which the subsequent tariff is being calculated. Expenditure forecast statement and tariff change notice 38 1 The Secretary of State must publish on the GOV.UK website a statement (an “expenditure forecast statement”) in accordance with this regulation. 2 For that purpose, the Secretary of State must determine as at the latest assessment date— a for each tariff category, the forecast for expenditure in relation to the relevant plants that are in that tariff category; and b the increase in expenditure forecast in relation to each tariff category. 3 An expenditure forecast statement must set out, as at the latest assessment date— a each of the forecasts for expenditure referred to in paragraph (2)(a); and b each of the increase in expenditure forecasts referred to in paragraph (2)(b). 4 Paragraph (5) applies to a tariff where— a the tariff is the initial tariff for accredited domestic plants with a tariff start date in the tariff period immediately following the publication of the expenditure forecast statement (“tariff period A”); b the tariff differs from the initial tariff for plants in the same tariff category with a tariff start date in the tariff period immediately preceding tariff period A; and c the reason for that difference is not solely due to an increase or decrease in the retail prices index. 5 Where this paragraph applies, the Secretary of State must also publish with the expenditure forecast statement a notice (“the tariff change notice”) setting out that tariff and identifying the tariff period and tariff category to which it relates. 6 The expenditure forecast statement, and if applicable the tariff change notice, must be published by 1st September 2014 and 1st December 2014 and subsequently by 1st March, 1st June, 1st September and 1st December in each calendar year. 7 In this regulation— “estimated spend”, in relation to a relevant plant and an assessment date, means— ( A × B × C ) − D where— A is— if the relevant plant is an accredited domestic plant, the deemed annual heat generation; or in any other case, the amount of heat in kWh that will be the deemed annual heat generation for the plant if accreditation is given; B is— if the property to which the relevant plant provides heat was occupied for less than 183 days in the 12 month period ending on the RHI date for the plant, or the participant has notified the Authority that the property is occupied for less than 183 days in a 12 month period, the number of days the Secretary of State estimates that the property will be occupied in the 12 month period commencing on the assessment date divided by 365; or in any other case, 1; C is— if the relevant plant is an accredited domestic plant, the tariff applicable to that plant on the assessment date; or in any other case, the tariff that will be the initial tariff for the relevant plant if accreditation is given; and D is— if the relevant plant is an accredited domestic plant, the grant funding deduction for the relevant plant for the quarterly period that includes the assessment date, multiplied by 4; or if the relevant plant is not an accredited domestic plant, the total value of any grants from public funds for the costs of the purchase or installation of the relevant plant which were disclosed by the person making the accreditation application at the time the application was made divided by 7, or 0 if no such grant was disclosed; “forecast for expenditure” means the sum of the estimated spend at an assessment date for each relevant plant which is in a tariff category; “increase in expenditure forecast” means the difference between the forecast for expenditure for a tariff category— as at that assessment date; and as at the assessment date immediately preceding that assessment date; and “relevant plant” means a plant for which the first commissioning date is on or after the relevant date and where the plant is— an accredited domestic plant; or a plant for which an accreditation application has been made and has not been rejected by the Authority. PART 7 Ongoing obligations for participants Ongoing obligations: general 39 A participant (“P”) must comply with the following ongoing obligations, as applicable— a if the accredited domestic plant is a biomass plant, upon a request by the Authority P must provide to the Authority 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 for any of the costs of the purchase or installation of the accredited domestic plant other than any grant which was notified to the Authority 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 40(1)(i) or 40(1)(j) to the owner or owners of that property; g P must repay any overpayment in accordance with any notice served under regulation 60 ; h P must not move the accredited domestic plant to a new location; i P must comply with such other administrative requirements that the Authority may specify in relation to the effective administration of the domestic RHI scheme; j on receipt of a request for access under regulation 56 or regulation 63(3)(b) , P must— i allow the Secretary of State, the Authority or the Authority’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 P must comply with any other requests by the Secretary of State under regulation 63(3)(c) ; l 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 allow the Secretary of State, the Authority or the Authority’s authorised agent reasonable access in the event of a request under regulation 56 or regulation 63(3)(b) and will co-operate with such a request; and m P must not seek accreditation under the Renewable Heat Incentive Scheme Regulations 2011 for an accredited domestic plant, or any other plant which provides heat to the same RHI property as an accredited domestic plant.

Ongoing obligations: annual declarations 41 A participant (“P”) must submit a declaration each year to the Authority, at such time and in such form as the Authority 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 Authority before the accreditation application was determined; or ii funding from any other source (other than under a loan or a Green Deal Plan for which an owner is liable to make, or has made, payments) 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 Authority of the installation of that plant under regulation 40(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 Authority, the Secretary of State or the Authority’s authorised agent for the purposes of carrying out any function under these Regulations; and f where the Authority 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 42 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 PM and NOx. Ongoing obligations: metering 43 1 This regulation applies to a participant (“P”) where the Authority 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 Authority 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 Authority 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 Authority 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 Authority may request; and b by the date (if any) specified by the Authority or at such regular intervals as the Authority may request to enable it to discharge its functions under these Regulations. 6 Nothing in this regulation prevents the Authority from accepting further data from a participant, if the Authority considers it appropriate to do so. Ongoing obligations: provision of information 44 1 A participant (“P”) must provide to the Authority on request any information which P holds and which the Authority 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 Authority. 3 P must comply with any request for information under paragraph (1) within 28 days of the request or such later date as the Authority may specify. PART 8 Changes affecting accredited domestic plants Review of accreditation following notification of a change in circumstances 45 1 This regulation applies where the Authority receives a notification under regulation 40 and regulations 47 and 48 do not apply. 2 Where this regulation applies, subject to regulation 46 (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 Authority may— a require the participant to provide such of the information specified in Schedule 4 and any declarations the Authority 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 Authority 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 may continue to be an accredited domestic plant. 5 Following a notification under paragraph (4) the Authority must resume payment of RHI payments in accordance with these Regulations. Changes affecting whether accredited domestic plants must be metered 46 1 This regulation applies where— a a metering statement has not been provided for an accredited domestic plant; b the Authority has reviewed the accreditation of an accredited domestic plant under regulation 45 or has carried out an investigation under Part 10; and c the Authority considers that, were an accreditation application made in respect of the accredited domestic plant on the date on which the Authority 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 Authority has provided the participant with a metering statement under paragraph (5). 3 The Authority 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 Authority 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 regulation 27 for the period commencing on the tariff start date and ending on the date on which the Authority received the notification under regulation 40 or commenced its investigation under Part 10; b regulation 28 for the period commencing on the date on which the Authority 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 Authority received the notification under regulation 40 which led to the review under that regulation, or commenced its investigation under Part 10, and ending on the day before the date on which the Authority provides the participant with a metering statement. Replacement plants 47 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 Authority received the accreditation application for the replacement plant. Changes in ownership of accredited domestic plants 48 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 Authority becomes aware of the transfer of ownership, no RHI payment may be made until— a the new owner has notified the Authority of the change in ownership and has confirmed, if the plant is owned by more than one person, that they have the authority from all owners to be the new participant; and b the Authority has taken the steps set out in paragraph (5). 3 On receipt of a notification under paragraph (2), the Authority may— a require the new owner to provide such of the information specified in Schedule 4 and any declarations as the Authority 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 Authority 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 Authority 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 Authority 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 Authority, the plant shall on the expiry of that period cease to be an accredited domestic plant and accordingly no further RHI payments are to be paid for the plant. 7 The period specified in paragraph (6) may be extended by the Authority where the Authority 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 a transfer of ownership of all or part of an accredited domestic plant takes place; and b that accredited domestic plant is then owned by more than one person, the Authority may require any person claiming to have the authority from all owners to be the new participant to provide to the Authority, in such manner and form as the Authority may request, evidence of this authority. PART 9 Metering and monitoring agreements Additional payments where a registered metering and monitoring agreement relates to an accredited domestic plant 49 1 The Authority must determine registration applications in accordance with this Part. 2 Subject to regulations 53 and 55 , where the Authority has given registration for a metering and monitoring agreement, the Authority must make metering and monitoring payments to the participant who is a party to that agreement. 3 Metering and monitoring payments accrue from the date on which registration is given and continue to accrue until the earliest of the following dates— a the tariff end date for the accredited domestic plant to which the metering and monitoring agreement relates; b the date on which the metering and monitoring agreement comes to an end or is terminated; or c the date on which registration is withdrawn under regulation 55 . 4 The Authority may— a decide on the frequency of any metering and monitoring payments; and b make metering and monitoring payments in advance, in arrears, or partly in advance and partly in arrears. 5 Schedule 7 has effect. Registration applications 50 1 A registration application for a metering and monitoring agreement may be made by— a a participant, if the agreement relates to that participant’s accredited domestic plant; or b an owner of a plant which is the subject of an accreditation application, if the agreement relates to that plant. 2 A registration application must be made to the Authority and be supported by— a a copy of the agreement; b confirmation by the metering and monitoring installer that— i measuring instruments have been installed under the agreement in accordance with the requirements of the agreement set out in paragraph 3 or 4 of Schedule 7; ii any eligible meters and temperature sensors installed under the agreement meet the requirements of the agreement in relation to accuracy set out in paragraph 5 of Schedule 7; c a declaration that all information provided in support of the registration application is accurate to the best of the applicant’s knowledge and belief; d if the applicant is a landlord, a declaration confirming that all occupiers of the RHI property have consented— i to the installation of any measuring instruments under the metering and monitoring agreement; ii to the collection of information relating to the use of the plant under that agreement; and iii on receipt of a request for access under regulation 56 or regulation 63 , to allow the Secretary of State, the Authority or the Authority’s authorised agent, as applicable, access to the RHI property to carry out any of the activities described in that regulation and to co-operate with such a request; and e such other declarations or information about the metering and monitoring agreement or the plant as the Authority may require, which may include evidence to support any declarations. 3 In order to determine whether to give registration, the Authority may— a arrange for a site inspection to be carried out; and b verify any information provided by the applicant against any other information available to it, including any information provided by the metering and monitoring installer or available to it on the MCS register. Conditions of registration 51 1 When giving registration, the Authority must make that registration subject to the following conditions— a the participant must, on receipt of a request for access under regulation 56 or 63 allow the Secretary of State, the Authority or the Authority’s authorised agent, as applicable, access to the RHI property to carry out any of the activities described in that regulation and co-operate with such a request; b the participant must submit a declaration each year to the Authority, at such time and in such form as the Authority may request, confirming that— i the metering and monitoring agreement is still in force and its terms are being adhered to; ii there has been no change to the agreement which could affect whether the requirements specified in Schedule 7 continue to be met; iii if the participant is a landlord, the participant has ensured that all occupiers of the RHI property have consented to the collection of information relating to the use of the accredited domestic plant under the metering and monitoring agreement; c the participant must notify the Authority if any change is made to the metering and monitoring agreement, including if the agreement is assigned by the metering and monitoring installer or the participant, or if the metering and monitoring agreement comes to an end or is terminated; and d the participant must give the Authority access to the information collected under the metering and monitoring agreement on receipt of a request from the Authority. 2 The Authority may make registration subject to any additional conditions it considers to be appropriate. Registration 52 1 Where paragraph (2) applies, subject to regulation 53 , the Authority must— a give registration; b notify the applicant that the registration application has been successful; c enter on the central register the details of the metering and monitoring agreement, the applicant’s name and such other information as the Authority considers necessary for the proper administration of the domestic RHI scheme; and d notify the applicant of any conditions attached to the registration. 2 This paragraph applies where— a a registration application has been properly made in accordance with regulation 50 ; b the Authority has given accreditation for the plant under regulation 21 or will give accreditation at the same time as it gives registration; c the Authority is satisfied that the metering and monitoring agreement meets the requirements specified in Schedule 7 (or, if the plant has not yet been given accreditation, the agreement will meet the requirements when the plant is given accreditation and the owner becomes a participant); and d the Authority has no reason to believe that— i the terms of the agreement are not being or will not be complied with; ii measuring instruments have not been installed in accordance with the requirements in paragraph 3 or 4 of Schedule 7; or iii any eligible meters or temperature sensors installed under the agreement do not meet the accuracy requirements in paragraph 5 of Schedule 7. Exceptions to duty to give registration 53 1 The Authority must not give registration if paragraph (2), (3) or (4) applies. 2 This paragraph applies if the giving of registration would cause the total cost of all metering and monitoring payments payable for— a the period commencing on the relevant date and ending on 31st March 2015 to exceed £0.58 million; or b the period commencing on 1st April 2015 and ending on 31st March 2016, or any subsequent period commencing on 1st April and ending on the subsequent 31st March, to exceed £2.42 million. 3 This paragraph applies if the agreement for which registration is sought relates to an accredited domestic plant for which another metering and monitoring agreement has been given registration which has not been withdrawn. 4 This paragraph applies if the Authority has advised the applicant that further information is required before registration can be given and that information is not provided within 12 weeks of the date on which it was last requested. 5 Where the Authority does not give registration it must notify the applicant that the registration application has been rejected, giving reasons. Changes affecting registration 54 Once the Authority becomes aware that a participant has transferred to another person (“a new owner”) ownership of all or part of the accredited domestic plant to which a registered metering and monitoring agreement relates, no metering and monitoring payment may be made until— a the new owner has notified the Authority under regulation 48(2)(a) ; b the Authority has taken the steps set out in regulation 48(5) ; c if the Authority requests that the new owner provide further information about the metering and monitoring agreement, that information has been provided; d if the Authority decides to review the registration, the Authority is satisfied that— i the metering and monitoring agreement continues to meet the requirements specified in Schedule 7; and ii the terms of the metering and monitoring agreement are being complied with; and e the Authority has updated the central register and notified the new owner of this.
