I got a copy of my ICB report some time back and as far as I can recall the information from MBNA was pretty recent (maybe a month or two behind). Think I have long since disposed of the report, but will take a look and post again if I can find it. No details of balances, just whether the bill had been paid or not as far as I can recall, though I was slightly more interested that AIB had failed to submit details of 2 mortgage accounts.
Why is the timing of interest? If you are looking for a new credit facility from a lender, you can probably just provide copies of your credit card statements to show you have paid it if it has not fed through to the ICB.
