When does an employer have to re-enrol automatically workers who have opted out after auto-enrolment into a pension scheme?

Workers can opt out of a pension scheme within one month of being auto-enrolled by their employer. Employers must automatically re-enrol eligible jobholders who have opted out every three years.

The employer can choose its re-enrolment date from within a six-month window beginning three months before the third anniversary of its staging date or duties start date, and ending three months after that anniversary. For example, if an employer's staging date was 1 October 2015 it could choose a re-enrolment date between 1 July 2018 and 31 December 2018.

The employer must complete re-enrolment of its eligible jobholders within six weeks of its chosen re-enrolment date. However, membership of the pension scheme must be backdated to start from the re-enrolment date.

Employers cannot choose a different re-enrolment date for different sections of the workforce, or for individual workers. The same date applies across the employer's workforce. Employers cannot use postponement at their re-enrolment date.
