Switching accounts to same banking group as creditor?

Hi, I'm new to this so perhaps someone could offer advice...

I have been struggling with huge credit card debts (13 cards) and bank loans (2) for some time and until now I've always managed to pay the minimums. Now things have spiralled out of control and I can do it anymore as there isn't enough money to go around. Initial advice from the CAB (while I'm waiting to see their money advisor, is to switch current accounts asap before my bank gets wind of my difficulties, as I have a outstanding credit card debt, two personal loans and a huge overdraft with my current account provider.

As I have so many credit cards, the choice of banks that aren't in the same banking group as my creditors is small - I've already been turned down by A&L today - I'm determined to switch as soon as a I can, as yet I haven't defaulted on anything, but couldn't manage the minimum on one of my larger repayments that is due by the 24th, so that will be the start of the difficulties.

My question is - if I end up getting a current account with a provider that is in the same banking group as one of my creditors (eg Citibank owns Egg, Natwest is part of RBS, etc) will they be able to take money from my account, as they would if it was the same bank?

Thanks for any help - sorry if this is a silly question!
