You may be required to book an appointment in advance to open a bank account at your chosen branch.
Please note that this may also be time consuming because many students will also be setting up accounts at the same time and appointments near LSE fill up quickly. However registering online in this way can save you time.
Some banks may allow you to book an appointment before you arrive in London, which can save you a great deal of time. If you book an appointment in advance, you may want to book your appointment at least a day or two after your registration date, or you may not have access to all the necessary documents to open an account. Also, be sure that your bank appointment does not clash with compulsory events, lectures or seminars/classes.
Always give yourself enough time to obtain the documentation you will need.
TOP TIP: You may find that it is easier to book an appointment at a bank branch further away from LSE or halls of residence. Once your account is set up, you can usually do business with any branch of your bank.
