    If you are staying in the UK for more than 6 months, it may be useful to open a UK bank account. There are a lot of advantages of having a UK current (checking) account:

    Paying bills

    Many landlords prefer to collect rent directly from a bank account.

    You may be able to obtain cheaper services if you pay bills directly from a bank account，e. g. telephone, gas/water/electricity.

    If you are given a chequebook, you can also write cheques as a safe way of paying for things.

    Cash

    You can easily obtain money from cash machines，or pay directly from your account using a debit card(借记卡).

    Saving money

    It is generally cheaper to use a UK account than it is to pay by credit card(信用卡)or withdraw (提取) cash from a foreign bank.

    Employment

    If you work in the UK，some employers require you to have a bank account so that you can get your pay.
