Hi Marvin and welcome to the forum.
An IVA sounds like an option for you, but you do need to speak to a professional. Vist
www.iva.com for a list of companies and reviews. Give one or two a ring and you will receive free and impartial advice as to all the options open to you and the best way forward for your circumstances.
As to the banks, do you have debts with them? If so, then you need to open another account with a non creditor, the Co-op comes highly recommended. If not, then there is nothing to stop you continuing to use the accounts but any overdraft facility should be removed.
If either of them are HSBC or First Direct and you enter an IVA then they will close your account. They have a nasty habit of doing that.
