If you have already accepted a place through Clearing or Adjustment, you should tell the people who deal with your application for student finance about your change of course and/or University.
They can then make the necessary amendments for any financial help you're entitled to.
I've already applied for funding
If you have already applied for student finance but your course or university details have changed due to the clearing process, you will need to inform your funding authority of the changes. You can do this quickly and easily by logging into your student finance account and changing your details – even if you applied on paper.
