The Pensions Increase (Review) Order 2019

Under section 59 of the Social Security Pensions Act 1975 (c.60) where the Secretary of State for Work and Pensions, under the Social Security Administration Act 1992 Act (c.), directs the sums in s.150(1)(c) are to be increased by a specified percentage, the Treasury shall provide by Order for the increase in the rates of public service pensions. The Pensions (Increase) Act 1971 (c.56) defines certain terms and sets out when a pension “begins” (the day after the last day of service in respect of which the pension is payable) and how the increase applies to lump sums.
