Credit scoring is an automated technique used by lenders to help them decide whether or not to lend. The information included on your credit report, together with the information you provide on an application form to a shop or lender can be used to calculate a credit score. This helps the company identify the risk in offering you credit and helps them to lend responsibly. Credit scores do not take account of gender, religion or race.
