yes you can change your address at another branch but I'm sure it involves closing your current account and depositing into your new account even though its the same bank. So then there's another problem for next year's visa extension, you have to show your money is in the bank for 2 months before and 3 months after (easy for the first extension) but when you can't produce a full year's statement (although you can show the 2 months prior) they will clearly see you didn't keep the required amount in for the 3 months after you last did your extension as your previous account has now gone and you'll find your previous branch probably won't help you (although it could be the same bank)
