Your credit report may include information such as credit cards, loans, payment history, and public financial records. Lenders review this report when deciding whether to approve credit applications.
Checking your credit report regularly can help you detect errors or fraudulent activity early. If incorrect information appears on your credit report, you can request corrections through the credit reference agency.
Why your credit score matters
Your credit score UK profile can affect many financial decisions. Lenders use credit scores to estimate the likelihood that a borrower will repay money on time.
A higher credit score may help you qualify for better financial products, including lower mortgage rates, higher credit card limits, and improved loan approval chances.
A low credit score does not necessarily prevent borrowing, but it may result in higher interest rates or stricter lending conditions.
