Details..details... You didn't indicate you were a full-time student !
Depending on whether your parents "can" claim you as a dependent....that could very well impact your ability to claim TN, as usually, if parents can claim a full-time college student as a dependent, then the student must remain a resident of the parent's state.....as long as you are under age 24 at the end of 2024, and do not provide more than half your support.
So if you will be under age 24 at the end of 2024, then what support is provided by your parents (pay for college and living expenses in London??) may come into play.

If this is the case (under age 24 all of 2024)...then it's getting way beyond my ability to suggest how your situation may properly evolve.
