This practice note examines the processes that a UK employer must follow when automatically enrolling eligible jobholders in a pension scheme, as well as considering jobholders' rights to opt out of membership or opt in if they choose to do so. The note also examines the statutory provisions allowing employers to operate a three-month postponement period before auto-enrolling eligible jobholders, and summarises the main points about the duty on employers to automatically re-enrol jobholders who have previously opted out every three years.
