My husband wants to transfer some of his credit card balances to a 0% card, he’s been approved but out of the 3 cards it only let him transfer from one, a barclaycard. He also has an HSBC one and an MBNA one, I presume they must be in the same banking group as the new one (Lloyds). Are we allowed to transfer from those to his barclaycard and then transfer that balance?
