Currently sitting in the office on leave doing admin and stumbled across a fact which hasn't been widely published and many may not realise:
If you are paying into an AVC to top up death in service or enhance spousal benefits, those AVCs will now cease owing to AFPS 15 providing comparable benefits automatically. Obvious when you think about it really, but with the pace of life and ever changing policy how many have time to sit down and go through the fine detail.
If you're paying into an added years AVC there's no change; everyone else will see a bit more in their monthly pay.
