penny.l, hello and welcome to the forum. The defaults will appear on your credit file for 6 years from the date your IVA was accepted.
I had a credit card, personal loan and a current account with HSBC.
When I checked my credit file all the defaults were listed individually. They have to be listed individually because they are seperate credit agreements each with their own account number.
Contact your bank or IP and ask them how can the bank register those accounts as defaults when you where already into an IVA with them? The accounts should state IVA or something along those lines on your credit file. A creditor doesn't have to send notification of a default by registered post. They do have to send you a default notice, but by regular post.
I am surprised they designated the accounts as defaults and not use some IVA designation AFTER you've been making payments for over a year into your IVA. I don't know if this can be done or not with IVAs.
An expert will come along who can assist you further.
Take care
All I have left is my humour.
