I have an existing credit card with NAB. Let's say for $10,000.
They've offered me a pre-approved guaranteed increase to $15,000.
Does anyone know, if I accept this, does this go onto my credit history?
There isn't a credit check, there's just a declaration that you can meet the higher minimum repayments of $x, plus you don't see a change in your circumstances.
In my experience, no it doesn't. Only if you request an increase
