Each part of the UK has it's own funding agency. They look after government funding for students, for example fees for your course (known as tuition fees) and student loans.
The funding agency you apply to depends on which country you normally live in. If you normally live in Scotland, you'll apply to the Student Awards Agency Scotland (SAAS).
You can also look at other ways of paying the costs of university.
Student funding for part-time courses
You may be able to get help with your tuition fees if you're studying a part-time course.
You also may be able to apply for other sources of funding.
