When you get admission into the university you’ll have to pay a deposit in the beginning for them to issue you a CAS. CAS is used for your student visa purposes. Usually the deposit can vary between £1,500 - £4,000. For most cases i’ve seen £2,000.

Once you come to the UK you must either pay the remaining total in one go or you can also pay remaining on a payment plan. This applies with most universities so just double check with them before applying.

Also note that when you apply for your student visa you’ll have to show the total uni fee in your account minus any advance you’ve paid. Most students usually borrow from someone they know and give it back after they get their visa.

Universities also provide scholarships as well, it’s very common. I would suggest applying to a few universities that you prefer instead of only one and then finalize the best suitable choice you have. This is what I know and have seen myself until now.
