(a)before the end of 3 months after P’s first day of eligible service (or within any longer period the scheme manager considers appropriate); or
(b)before the end of 3 months after the automatic re-enrolment date (or within any longer period the scheme manager considers appropriate).
(2) If paragraph (1)(a) applies, P is taken never to have been in pensionable service under this scheme in relation to that eligible service.
