Most people dont come out as trans at UK secondary school ages, I dont think. Often its just not something you are aware of, so I think a lot of trans teens, if they aren't out, will often get homophobia instead. Like a feminine male bodied person, or even someone in the early stages of transitioning (so maybe part time), would be percived by 14 and 15 year olds as a gay. And transmen are mistaken for lesbians all their life, unless they pass very well, which often can only be so much without T.

But homophobic bullying can be very similar to transphobic bullying, infact the two basically are interlinked. Percieved gays, or people with obvious gender variant behaviour (trans or not, so like tomboys), get picked on for things. Like being a percieved lesbian means you 'want to be a man'.

Anyway, I personally was given a lot of crap since I first started presenting as male, but not identifying as it. So basically I didnt look like a girl, but I was open that I was. This lead to terms like 'shim', 'he/she', 'sheman', 'shemale', and such like, being frequently and consistantly, and unpleasantly.

My boyfriend got a lot of similar crap. My best friend got it from his apparent lesbianism.
