The banking system has undergone huge changes over the past few years and it should be relatively straightforward to change your bank. Many banks are currently offering incentives to encourage you to change. Some accounts offer ‘rewards’ for spending on certain products or services however if you like going into your local branch and speaking to a human being many of the online alternatives may not be for you!
As with all these things, shop around and consider carefully what you want from your bank before making the change.
