I think that the time it takes is just a sign of the times we now find ourselves in.
I phoned the SIA yesterday to find out how much longer it would take and after getting a recorded message the first 6 times I finally got through to talk to a person.
I was told that a licensing officer had to go through every application one by one to vet them and that because I'd received my copy of my CRB disclosure, it would not be more than a month to finally get approval.
So much beauracracy to get through just sends efficiency out of the window. If I had known that it would take this long I probably wouldn't have bothered.
