Tegwin - MustFly is bang on - read and understand his post. If you do decide to join any of the Services, keep your current RW experience to yourself until you've got some way into the system. I'm sure you are a good, safe pilot, but that doesn't mean you fly the way the RN/RAF/AAC want you to fly. Don't think that your PPL(H) means anything, particularly to QFIs who have been flying for longer than you might have been alive.
You'll be quicker to learn for the first 15-20 hours, but after that you'll find the playing field levels out - be prepared for that.
