I've just recieved a letter from the IVA Helpline, which is a new one for me. As for DPA, since the register is in the public domain anyway these leeches technically not doing anything wrong. Doesn't make it right though.

I have a step account with Natwest and had no problems opening a savings account or an ISA with them. They were more than aware of the IVA at the time. The branch that I use have been nothing but helpful and discrete (in terms of the IVA).
