Rounding of numbers 3 Where (apart from this article) any rateable value determined under this Order would include a fraction of a pound— a the fraction shall be made up to one pound if it would exceed 50p, and b the fraction shall be ignored if it would be 50p or less. Disapplication of normal basis of valuation 4 In the case of electricity hereditaments, paragraphs 2 to 2B of Schedule 6 to the Act shall not apply, and the rateable values of such hereditaments shall be as determined under the following provisions of this Order. PART II INITIAL RATEABLE VALUES Interpretation 5 In this Part— a in any formula— B is the figure applicable in relation to the relevant year for the purposes of paragraph 5(3) of Schedule 7 to the Act; C is the figure applicable in relation to the relevant year for the purposes of paragraph 5(4) of Schedule 7 to the Act; I is the figure for the retail prices index for September in the relevant preceding year; and in relation to any class of hereditaments— R is the recalculation factor applicable to that class determined under Part IV in respect of the relevant preceding year; RV is the rateable value of that class in the relevant preceding year; and T is the amount specified in relation to a class of hereditaments in column 1 of the Schedule; U is the recalculation factor applicable to that class determined in accordance with Part IV in respect of the relevant year; and “the standard formula” means the formula T + U. Rateable values in 1990/1 6 In relation to each class of hereditaments— a Where T is greater than the relevant maximum amount calculated in relation to that class under article 7, the rateable value of that class in the year beginning on 1st April 1990 shall be the relevant maximum amount; b where T is less than the relevant minimum amount calculated in relation to that class under article 7, the rateable value of that class in the year beginning on 1st April 1990 shall be the relevant minimum amount; c where neither paragraph (a) nor paragraph (b) applies, and in any case where there is no amount specified in relation to the class in column 2 of the Schedule, the rateable value of that class in that year shall be T. 7 The relevant maximum amount in respect of a class of hereditaments is the amount produced by calculating in accordance with the formula— 1.2A M and the relevant minimum amount in respect of a class of hereditaments is the amount produced by calculating in accordance with the formula— 0.895A M where A is the amount specified in relation to that class in column 2 of the Schedule, and M is the non-domestic rating multiplier applicable to that class in pursuance of paragraph 2 of Schedule 7 to the Act. Increasing rateable values 8 1 This article applies to any class of hereditaments in relation to which the rateable value in the year beginning on 1st April 1990 is determined as provided in paragraph (a) of article 6. 2 The rateable value in the year beginning on 1st April 1991 of any class of hereditaments to which this article applies shall be determined in accordance with paragraph (3). 3 For the purposes of paragraph (2), where in relation to a class of hereditaments a calculation in respect of that year according to formula 1, that is to say— RV × 1.2 1 + I - BC + U produces an amount less than that produced by a calculation in accordance with the standard formula, the rateable value of that class of hereditaments in that year shall be the amount calculated in accordance with formula 1; and in any other case that rateable value shall be the amount calculated n accordance with the standard formula. 9 1 This article applies to any class of hereditaments in relation to which the rateable value in the year beginning on 1st April 1991 falls in pursuance of article 8 to be determined in accordance with formula 1. 2 The rateable value in any intermediate year of any class of hereditaments to which this article applies shall be determined in accordance with paragraph (3). 3 Where in relation to a class of hereditaments and any such year a calculation in respect of that year according to formula 2, that is to say— ( RV - R ) × 1.2 1 + I - BC + U produces an amount less than that produced by a calculation in respect of that year in accordance with the standard formula, the rateable value of that class of hereditaments in that year shall be the amount calculated in accordance with formula 2; and in any other case it shall be the amount calclated in accordance with the standard formula. Decreasing rateable values 10 1 This article applies to any class of hereditaments mentioned in the Schedule in relation to which the rateable value in the year beginning on 1st April 1990 is determined as provided in paragraph (b) of article 6. 2 The rateable value in the year beginning on 1st April 1991 of any class of hereditaments to which this article applies shall be determined in accordance with paragraph (3). 3 For the purposes of paragraph (2), where in relation to a class of hereditaments a calculation in respect of that year according to formula 3, that is to say— RV × 0.87 1 + I - BC + + U produces an amount greater that that produced by a calculation in accordance with the standard formula, the rateable value of that class of hereditaments shall be the amount calculated in accordance with formula 3; and in any other case it shall be the amount calculated in accordance with the standard formula. 11 1 This article applies to any class of hereditaments in relation to which the rateable value in the year beginning on 1st April 1991 falls in pursuance of article 10 to be determined in accordance with formula 3. 2 The rateable value in any intermediate year of any class of hereditaments to which this article applies shall be determined in accordance with paragraph (3). 3 Where in relation to a class of hereditaments and any such year a calculation according to formula 4, that is to say— ( RV - R ) × 0.87 1 + I - BC + U produces an amount greater than that produced by a calculation in accordance with the standard formula, the rateable value of that class of hereditaments in that year shall be the amount calculated in accordance with formula 4; and in any other case it shall be the amount calculated in accordance ith the standard formula. PART III GENERAL PROVISION FOR RATEABLE VALUES 12 In the case of— a any class of hereditaments to which paragraph (c) of article 6 applies, in any year beginning on or after 1st April 1991, b any class of hereditament the rateable value of which falls in pursuance of article 8(3) or 10(3) to be determined in accordance with the standard formula, in any year beginning on or after 1st April 1992, and c any class of hereditaments to which article 9 or 11 applies, in any year beginning after an intermediate year, the rateable value of that class in such a year shall be the amount produced by calculating in respect of that year in accordance with the standard formula. PART IV ANNUAL RECALCULATION OF RATEABLE VALUES Electricity generating hereditaments 13 1 In relation to each class of hereditament mentioned in division A of Part I or division A of Part II of the Schedule, the recalculation factor in respect of any relevant year shall be the figure produced for that class by calculating in accordance with the formula— £ 12 , 810 ( D - d ) where— D is the total net capacity of the relevant designated person on 31st March in the relevant preceding year, and d is the total net capacity of that person on 31st March 1990. 2 In this article— “total net capacity”, in relation to a designated person, means the total declared net capacity of all generating plant occupied by that person; and “declared net capacity” means the highest generation of electricity (at the main alternator terminals) which can be maintained indefinitely without causing damage to the plant, less so much of that capacity as is consumed by the plant, in each case expressed in megawatts to the nearest one hundredth part of a megawatt. Electricity transmission hereditaments 14 In relation to each class of hereditament mentioned in division B of Part I or division B of Part II of the Schedule, the recalculation factor in respect of any relevant year shall be the figure produced for each class by calculating in accordance with the formula— T k - KK where T is the amount specified in relation to that class in column 1 of the Schedule; k is the estimated number of circuit kilometres of main transmission line occupied by the relevant designated person on 31st March in the relevant preceding year; and K is the estimated number of circuit kilometres of main transmission line occupied by that person on 31st March 1990.
