Option 1: ATMs
Using your UK bank account can be your best option; afterall, money will be deposited to it if you’re on a UK-run scheme or have taken out a loan, plus if you need the odd top-up and your parents can oblige, it’s a lot easier to sort out. You can have a look round all banks to see which one offers the best deal for you - remember, it doesn’t necessarily have to be a student account - you can always speak to your branch manager and arrange an interest free overdraft. It might not be as generous as that of a student account, but you could still make the most of it, should needs be. It’s also a wise decision to leave one bank card at home, so it might be more beneficial for you to have two accounts. Some banks charge more than others if you use them abroad - do your research! You’ll also need to find out how much you’ll get charged, should you use your card in a restaurant or at a bar. Websites like moneysupermarket.com might prove useful when it comes to comparing features and pricing.

Option 2: Opening a foreign bank account
This might prove to be a little tricky and quite a bit of faff, if you’re just planning on going abroad for a semester. However, if you are planning on getting paid in foreign currency, or are settling in for at least 6 months, you should look into opening a bank account abroad. You’ll avoid transfer charges, which can be quite steep, if you are getting money from a source in euros, dollars or any other foreign currency. Another advantage to getting a foreign bank account, generally speaking, means you won’t be charged for taking money out, or paying with your card (though do check with your bank first). The European Commission offers a pretty good guide, as to opening a bank account within the EU. International banks, such as HSBC and Santander can give you advice about spreading your money, and your bank account, overseas. 

Option 3: Wiring money
Western Union offer a good service, if you’d like your money ‘leaked’ to you - that is to say, in lump sums. Watch out, however, for the transactional fees, as they can be quite pricey, especially if you are only being wired a small amount. It’s also quite unwise to have large cash sums stashed away, as the opportunity for theft is quite common.

Option 4: Travellers’ cheques
This could prove to be quite a good option for students, especially those who aren’t very good with money. You’ll be forced to budget accordingly, by dividing up equal or different sums and setting yourself a limit each week. You won’t have the hassle of having to set up a bank account, nor incur charges from your account back home, but you could end up paying certain charges, so check with each country before you buy.

You will also need some money in cash once you arrive, so make sure you’ve ordered this plenty of time ahead - there’s no point in getting to the Post Office and hearing that they don’t have any more dollars left. They also don’t charge any commission when changing money, as opposed to other bureaux de change.
