17.—(1) Subject to paragraph (7), a firefighter member who—
(a)(i)satisfies an eligibility condition; and
(b)on taking up a different role within the fire and rescue service or becoming entitled to a different rate of pay in his existing role, suffers a reduction in the amount of his pensionable pay such that the amount to be taken into account in the calculation of the pension to which he will be entitled at normal retirement age is less than it would otherwise have been,
is entitled to two pensions.
(2) The pensions shall be calculated as mentioned in paragraphs (3) and (4) and shall become payable as mentioned in paragraph (5).
(3) The amount of the first pension is that found by multiplying the member’s pensionable service up to (but not including) the day on which paragraph (1) first applies to him by the final pensionable pay to which he would have been entitled had he retired on that day, and dividing the resultant amount by 60.
(4) The amount of the second pension is that found by multiplying the member’s pensionable service on and after the day on which paragraph (1) first applies to him by the final pensionable pay to which he is entitled on that day, and dividing the resultant amount by 60.
(5) Subject to paragraph (6), the pensions become payable on the date on which a pension would have become payable to the member in whichever of the circumstances referred to in articles 11, 12, 13, 15 and 16 applies in his case.
(6) A member who is entitled to two pensions under this article may, by notice in writing to the Board, before leaving that employment, instruct the Board to make a single award which shall calculated in accordance with paragraph (7).
(7) The single award under paragraph (6) shall be calculated by—
(a)multiplying the aggregate of the periods of pensionable service used for the purposes of paragraphs (3) and (4) by the final pensionable pay used for the purposes of paragraph (4), and
(b)dividing the resultant amount by 60.
(8) If the member makes a contributions election, he shall be entitled to a single pension, calculated as mentioned in paragraph (3); and that pension shall be treated for the purposes of article 13(4) to (6) and article 14 as if it were a deferred pension to which he was entitled under article 13.
