Either case is determined by whichever is the highest.

The Civil Service pay structure and progression is different from NHS Agenda for Change (AfC), most local authority pay grades and other systems that have annual pay increments. For further details, please refer to the Information Sheet- Starting Salaries & Benefits attachment.
