Hi Judybaby73
With regard to a balance transfer, in general, there is no big deal. I have done this many times.
You tell the company with whom who hope to do business (BoS in your case) the amount you wish to transfer.
When you get your card and you activate it (you telephone them to do this) you let them know the amount you wish to transfer from another company.
It is advisable that you ring the original credit card company immediately prior to activating your new credit card account so that you have the exact balance (including any interest, if relevant, to transfer). When you are talking to your original credit card company you tell them that you are closing your account and you wish to know your closing balance.
You will have to ring them again to verify that your account is closed and that the relevant stamp duty, if applicable, has been paid. They will send you a letter stating that the stamp duty has been paid, you will then forward this to your new credit card company (in your case BoS)
I don't know what impact a balance transfer has on a credit limit. All I know is that when I made an initial telephone application with BoS, I was asked the value of my credit limit on my original credit card. The credit limit that I received, from BoS, was significantly less than that which I had on my old card - but the reality is that I had never used this limit and so, it doesn't make any difference to me.
