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, ensure that you are an enrolled student, have updated your term-time address to your London address and have 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 in-person 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.
