Along with meeting the academic and English language requirement, you will also need to meet the financial requirements demanded by the UKVI. You will require a 28 days’ bank statement, which should cover your cost of tuition after paying the initial deposit, and your cost of living for 9 months (because 3 months are usually summer breaks in the UK where you can work full time).
The statement must not be more than 31 days old while applying for the visa. The cost of living for London is £1,334/month, and 1,023/month for outside London.
Example:
Tuition fees: £13,000
Initial payment (required by most universities to accept the offer): £3,000
Remaining tuition fee: £13,000 – 3,000 = £10,000
Cost of living (let’s take a London University for example): £1,334 X 9 = £12,006
Require amount in the bank statement = Remaining tuition fees + Cost of Living
=£10,000+12,006
=£22,006 for 28 days
