In my case (with the DG course) we pestered the course instructors and the STW at Halton for details on how we could gain the same accreditation as our civilian colleagues and were flatly told this wasn't available for service personnel.
I wouldn't take no for an answer if I were you. Sadly, that sort of situation is still widespread. You probably won't be popular for pushing the issue, and you'll have to be thick skinned, but correct accreditation can be achieved. I'm told that it took years of hard work for military pilot training to eventually become accredited by the CAA.
