Credit Card Mortgage Query

Hi There,

I haven't missed a CC D/D payment but have gone over the limit 6/7 times in the past year. Limit was 2800, sometimes went as high as 2950. Have cleared balance in full since.

On the CCR report it has recorded the over limit balances. Going for a mortgage in June 2020, would this be a red flag for the banks? If I close the CC account will they still see that previous info?

Loan of circa 5k will be paid off by then also, no missed payments etc.

Thanks
