What is a Credit Report? - Help and Advice
A credit report details your personal credit history, including mortgages, credit cards, overdrafts, mobile phone contracts and even some utilities such as gas, electricity and water. If you're over 18 and have ever taken out credit, a credit reference agency is likely to hold a credit report on you.
Lenders - how they use your credit report
A credit report provides a snapshot of your credit accounts, repayment record and how well you are coping with your finances.
Lenders can only look at your report with your permission. They use it, along with information on your application and information they might already have, to decide whether to offer you credit - usually by calculating a credit score for your application.
They may also use it to decide how much to lend and to charge - for instance, people with an excellent record of handling credit may be offered higher credit limits and lower interest rates.
