If your CC's turnover/profit exceeds the needs required by the bank as surity then you have no problems. They should not check your or any of your partners credit records. They might if your company does not meet their requirements to cover the loan.
But I won't stress about it if your CC has been running at least 2 years and turns a nice profit![]()
They will still ask for surety. Unless you've already signed unlimited surety (if it is the original CC). Although you typically have to submit the latest CK1 or they will do a CIPRO search - so they will pick up the new member.
