A credit score or a credit rating is a tool used by many lenders to help determine if you qualify for a particular mortgage, loan, credit card or service.

By analyzing  the information on your credit report and other additional information you supplied as part of your application or other sources, lenders use a mathematical model to calculate a score that represents your credit history. This helps to indicate what kind of borrower you are, and how likely it is that you will manage your repayments.
