Your personal credit rating and your company credit rating are not the same thing. A company credit rating is an indicator that shows how solvent a business is, while your personal credit rating is your ability to pay. Depending on the form of your business, your credit rating may have a stronger or weaker effect on your company credit rating. For example, if you are a sole-proprietor, much less use personal accounts to run your business or take out a personal liability loan, your credit score will have a strong impact on your business credit rating. If the company is of a different organizational form, however, it is likely that your credit ratings will have little or no effect on each other, except in isolated cases.
