I'm 20, but there's no time that they ever ask for your age. They ask for your basic contact information, you get an email telling you whether you got in or not, and later they send you an info sheet you have to print out and bring with you. If you show up and look young enough to play Billy Elliot, that might give them pause, but as far as I know there's no official age limit.
