This term is relevant for those who become an employer for the first time on or after 1 October 2017 – such employers will immediately have to legally comply with automatic enrolment duties for their new member/s of staff. These duties apply immediately from the first day the first member of staff started working for them.
New employers after 1 October 2017 will not have a set staging date, but they’ll be able to use the three month postponement period*.
