Today, no. Next week, maybe, now that the lending criteria change on an almost weekly basis.
It would be advisable not to have any debt and decent savings before applying for a mortgage these days.
If all of your other attributes are strong i.e salary/length of employment/savings then the credit card should not matter. If you are borderline some lenders may take issue with it.
I was not asked about any credit cards, no request for statements or anything. I didn't have any credit card debt and never mentioned that to the bank.
I thought they would have checked but they didn't.
