To study a degree, you need to show that you have enough money to support yourself and pay for any outstanding course fees you may have.
For any course that is 9 months and longer, you will need £1,334 per month for your living costs. This means you will need to show a minimum of £12,006 for your application, plus any outstanding course fees.
Funds must be maintained in a bank account for at least 28 consecutive days and the bank document must not be more than 31 days old. You can show funds from a current account, deposit account, savings account or investment account.
You can also provide a loan letter if you received a student loan or a financial guarantee letter if you received official financial sponsorship from the relevant bodies. These letters must state how much money is granted to you for your course fees and/or maintenance. More detail can be found here.
