There are two options - either open a current account but please remember you will be credit searched when you apply; or you can open a savings account. Considering you will be depositing money into the account monthly and have a healthy balance, a savings account would allow you to gain interest. An easy access savings account allows you to deposit and withdraw money at any time with no penalties or restrictions. Currently the best internet easy access savings account is ICICI Bank paying 5.15% AER or Chelsea BS has the best branch-based easy access savings account paying 4.80% AER. Both providers are FSA regulated, however only Chelsea BS is a member of the Banking Code.
