If you are going to get a credit card, get one that does not have an annual fee. Always pay the balance off in full. Never withdraw cash using a credit card ( as well as being costly it doesn't look too good ).
If you have a current account with a Bank, and you have used it well, you should have a good credit rating built up with them, so try them first. You may find you do not need to get a credit card, depends on what you want a good credit rating for?
