In regulation 275 (Pensionable service limit), after paragraph (4) add—

“(5)

Where a member is also a member of the HPSS Superannuation Scheme 1995, any reference in this Part to “45 years” shall be taken to be a reference to a shorter period determined by the formula—

$\mathrm{SP}=45\mathit{\text{years}}-\mathrm{LSS}$

where—

• SP is the shorter period, measured in years and days, and

• LSS is the length of superannuable service (within the meaning of the 1995 Regulations), measured in years and days, giving rise to membership of the HPSS Superannuation Scheme 1995 and, in the case of a member of that Scheme who has become entitled to a pension (including a preserved pension) under that Scheme, including any period that was taken into account for the purpose of determining whether the member was entitled to that pension, or for the purpose of calculating the amount of that pension.”.
