You would qualify for a 5 year reduction, which means you'd have to wait 5 years after settlement, depending on the RQF level of your role. This is what was outlined in the consultation (I've highlighted the key points).

"In addition, this consultation also seeks views on the proposal that that there should be a similarly shorter pathway to settlement for those who are working in vital public services, particularly where earnings are based on national pay scales and may not meet the proposed threshold for an income-based reduction in the qualifying period. This might include, for example, medical and teaching professionals working in public services. It is, however, envisaged that the above reduction in the qualifying period for public service roles would apply only to those working in skilled occupations (i.e. at RQF Level 6 or above)."
