When an Authorising Officer resigns, leaves employment or becomes ineligible, the sponsor should appoint and report an eligible replacement without delay—before the departure where the organisation controls the timing. Current guidance requires the sponsor to have an eligible Authorising Officer throughout the life of its licence.
The familiar 20-working-day rule should not be treated as permission to leave the role vacant. Part 3 of the sponsor guidance expressly excludes replacement of the Authorising Officer or Key Contact from that general reporting period. It does not provide a separate 20-working-day grace period for the vacancy.
The departure must be analysed as a governance event, not merely an amendment to the Sponsor Management System. The organisation must identify every role and access right held by the departing person, appoint a suitable successor, preserve lawful system access, submit the correct replacement request and retain a reliable record of the transition.
