Hi T-Ruxpin,
While doing my CPL exams last year a guy at the CAA (Martin Marsh) told me that changes were afoot to all rotary exams although he had no details at the time. Sounds to me that these are now being phased in.
Martin Marsh is the man you need to speak to at CAA Gatwick, he is the guy that deals with QSPs at the CAA. A very helpful guy who will guide you down the shortest path to reach your goals. Ask him about any credits that the CAA may allow you, any exams you don’t need to do will save you time and money.
As for possible jobs.....well not the best time, but as you may not be starting the ground school until the middle of next year things may start to turn by the time you are ready to leave the forces. Some police forces will look at you once you have 1500hrs and unless you are one of the few (on Gazelle) then you will be multi engine qualified but I know of single engine guys getting jobs with the police.
If your budget will stretch then getting an IR will increase your chances but you will need to get a type rating on the IFR aircraft before you can start training. If you are currently twin engine then it's a six-hour conversion, if not then eight hours minimum.
