Hi Gallus, I’ve had similar issues with BOI when applying for a credit card, originally they requested 3 months statements from my current credit card provider-I queried this, and they advised they needed to see I was making repayments, I suggested the ICB would be of assistance to them in any checks they required, they said they would be doing that too!! I provided the credit card statements and they then requested a whole host of information including my employment contract, payslips and letters from my employer regarding my tenure etc.
(I can partially understand this, as I bank with UB and drop fund into our joint account fortnightly so it’s not deposited by my employer directly)
Now, I was simply wishing to do a balance transfer with this new card application(approx €1200), and I have a joint current account/mortgage with BOI for over 13 years with a hefty balance (part of which I have since used to clear the CC I was wishing to transfer to them). They can see the balance on the account, they can see funds are credited regularly, but they advised me that having a substantial balance in a current account does not mean I would use it to pay off any CC balance I would have with them!!
Anyhow, the piecemeal nature of the request from BOI were most annoying as well as hugely intrusive. I requested the return the information I provided them and close the application. Moving current account etc is the next step, but that’s such a bother when trying to align direct debits etc
I’d give up with your current potential lender and try elsewhere. Good Luck.
