Under section 59 of the Social Security Pensions Act 1975 as amended, and as modified by section 59A of that Act, the Treasury (in whom the functions conferred by those provisions are now vested) are required to provide by order for the increase in the rates of public service pensions. The increase is the percentage (or in some circumstances a fraction of the percentage) by which the Secretary of State for Social Security has, by direction given under the provisions of section 151(1) of the Social Security Administration Act 1992, increased the sums referred to in section 150(1)(c) of that Act. These are the sums which are the additional pensions in long term benefits, namely the additional pension entitlements accruing to employees in respect of earnings after 5th April 1978.

For pensions which began before 11th April 1994 the increase is 2.2 per cent. For pensions which began on or after 11th April 1994 the increases are as follows—

Pensions Beginning	Percentage Increase	Pensions Beginning	Percentage Increase
11th April 1994		26th September 1994
to	2.2%	to	1.1%
25th April 1994		25th October 1994
26th April 1994		26th October 1994
to	2.02%	to	0.92%
25th May 1994		25th November 1994
26th May 1994		26th November 1994
to	1.83%	to	0.73%
25th June 1994		25th December 1994
26th June 1994		26th December 1994
to	1.65%	to	0.55%
25th July 1994		25th January 1995
26th July 1994		26th January 1995
to	1.47%	to	0.37%
25th August 1994		25th February 1995
26th August 1994		26th February 1995
to	1.28%	to	0.18%
25th September 1994		25th March 1995

Deferred lump sums beginning on or before 25th March 1995 and which become payable after 9th April 1995 receive the same percentage increase as pensions which began on the same date. Article 4 of the Order provides for increases on certain deferred lump sums which became payable on or after 11th April 1994 and before 10th April 1995.

The Order also makes provision for the amount by reference to which any increase in the rate of an official pension is to be calculated to be reduced by the amount equal to the rate of the guaranteed minimum pension entitlement deriving from the employment which gives rise to the official pension. This is required by section 59(5) of the Social Security Pensions Act 1975 but by virtue of section 59A of that Act and the Transfer of Functions (Minister for the Civil Service and Treasury) Order 1981 the Treasury are empowered to direct that in respect of specified cases or classes of case either no such reduction be made or the reduction shall be less than the rate of the guaranteed minimum pension. Section 59(5ZA) was inserted into section 59 by section 5 of the Pensions (Miscellaneous Provisions) Act 1990. This applies section 59(5) to a widow’s or widower’s pension.
