If you live in a student hall of residence there is nothing to pay and you don't need to claim an exemption.
The university or college must apply for the exemption.
Student accommodation
Student accommodation that is not run by a university or college is not counted as halls of residence and is not exempt from Council Tax.
If you live in student accommodation (not halls of residence) you must apply for your own student exemption for your room
