moneysavvy:Try e mailing or phoning the credit card companies and ask what their rules are, regarding re-applying for a card. I think virgin offer the longest 0% rate for - worth remembering when they all apply around a 3% rate anyway.
Some go down to about 2.5% but the length is only about 9 months...i think Abbey offers 15 months too:

The Santander card, not the zero one, but it can only be applied for on the phone.
Obviously there may be further small print, i.e if you have transferred the debt of the card you previously had when you consolidated your debts, you may not be able to re-transfer that money back onto one of their cards if they catch you out!
Off the top of my head, i know Barclaycard allow you to apply for another card immedietly, so long as its a different card...not the same credit card (or the same credit card in 6 months).
Their platinum card offers 12 months at zero% but only has a 2.5% fee, so if you can handle it in a year, that has one of the lower handling fees:

They also have a long term BT rate of 6.3% for 3 years if you want that and there's no fee with that.
The flexi-rate card has 1.7% (same as MBNA's platinum plus) but that s only for 9 months, so its getting a shorter and shorter time, the lower the rate.
Their simplicity card has no fee for BT's too, 6.8% for the life of the transfer:

Have a look see what you like and could possibly get approved for, Barclays has a system which checks first and gives you a rough idea:

(I should make a thread on that seperatey i think).
