Sorry to butt in - are you NHS? If not, it sounds like you might be interested in a Medical Secretary/Waiting List Secretary type role. These often lead to being a PA for surgeons, consultants, senior nurses and management etc with a bit of experience. It also sounds like you’ve got the right experience to step in at either a band 3 or band 4 role and work your way up. If you’re in Scotland, band 3 is currently £21,709 - £23,603 and band 4 is £23,709 - £25,982. Not sure how long it’ll stay at those rates with the current ballots surrounding the pay rise as the 5% uplift was rejected. PA roles tend to be band 4 but can be band 5 if you’re willing to take on some management/supervisor duties too (band 5 is currently £26,104 - £32,915).
If you’re not in Scotland then obviously ignore the pay rates but the job roles should be more or less the same across the country. NHS is always a good place to get experience and then move onto somewhere private if you’re looking to earn more though
