a word of advice - i am in the process of changing, have only a small balance but want to pay it over a few months, so decided to go with Halifax... however, our cr card is with AIB and my hub is the main cardholder. I did not read all the small print (very bad really !!) but I applied for the card and got approval and when i called to transfer the balance i was informed that only the main card holder can do that and that the card has to be in his name with me as a named card holder - me thinks a bit stupid, but i'm sure there is a logical explanation!!
BOI are offering at good rate a the moment aswell.
Halifax give you 0% interest on balance transfers for the first 6 months
