Pension Schemes Act 1993

4 (1) Regulations may modify the provisions of Part III (other than sections 18, 19 and 66 to 68), Chapter III of Part IV and Chapter II of Part V (except, so far as they relate to personal pension schemes, the members of such schemes or rights in respect of them) in their application to cases in which—

(a) a person is employed at the same time in two or more employments (whether or not under the same employer); and

(b) at least one but not all of those employments is contracted-out employment,

with a view to enabling the employments to be treated either separately or together for the purposes of those provisions.

(2) Regulations may also modify those provisions in their application to cases in which—

(a) any description of benefit under a scheme is subject to a limit (however imposed) operating so as to prevent service beyond a particular length from qualifying for further benefits; or

(b) earners qualify for the benefits of a scheme by reference to both—

(i) service in employment which is contracted-out in relation to them by reference to the scheme; and

(ii) service in the same employment or another employment (whether or not contracted-out employment) before the scheme was contracted-out in relation to them or their employment.

(3) Regulations under this paragraph may include provision for securing that in the cases to which they apply an earner’s employment does not cease to be contracted-out employment only because his service for the time being does not qualify him for a guaranteed minimum pension.
