Opening a bank account
It is not possible to open a UK bank account until you arrive in the UK. However, it is likely to be one of the first things that you do because this is the safest way to keep your money. This will take you at least a week so you must make sure you have enough money for your first few weeks in your new city.
To open a bank account you will need to check individual bank requirements, but most require you to take your passport and introductory documentation from your university detailing your personal details and course of study. Speak to your university student union for more details or go to www.moneyadviceservice.org.uk for advice on budgeting and managing your money or the British Bankers Association for their guide for international students http://www.bba.org.uk/publications/entry/international-students/leaflets/
