Section 8 amends section 6(1)(b) of the Pensions (No. 2) Act to stipulate that automatic re-enrolment will not happen more frequently than once in every period of two years and nine months. The two years and nine months interval applies to the employer rather than the jobholder. This section is relevant only where the Department makes provision under section 6(1)(b) rather than section 6(1)(a).
