Regulation 4
This Regulation applies to—
a pension payable under Part II of the 1965 Act; and
a pension payable under Part I of the 1972 Act, being a pension calculated in accordance with section 8 of the 1972 Act (which provides for an alternative calculation of pensions by reference to the 1965 Act).
Subject to paragraph (3) below, a pension to which this Regulation applies shall, for the purposes of the Pensions (Increase) Act 1971, be treated as beginning on 16th October 1964.
Any increase under the Pensions (Increase) Act 1971 (as modified by paragraph (2) above) of a pension to which this Regulation applies shall not exceed the amount by which the basic rate of the pension falls short of the rate of the pension which would have been payable under Part I of the 1972 Act if the service in respect of which the pension is payable (including any days of such service beyond completed years) had been continuous service ending on 31st December 1972.
