Your credit rating will not be affected at all following your change of name. Whenever you apply for finance you will be asked to disclose your current name and any other names you have been known by. This allows the credit provider to access your entire credit history and score you accordingly.

In addition to the above, when you inform your bank or any other financial institution of your change of name they will in turn notify the major credit reference agencies. Both your old and new names will then be linked for the purposes of credit scoring.
