For posts on UKHSA Civil Service terms and conditions, new entrants to the Civil Service are expected to start on the minimum of the pay band. For existing Civil Servants and roles advertised across government, the rules of transfer apply, i.e., level transfers move on current salary or the pay range minimum, transfers on promotion move to new pay range minimum or receive a 10% increase. Either case is determined by whichever is the highest.
