A credit report is a factual record of your personal credit history made up of information from different sources like banks, building societies, local authorities and courts. If you’re over 18 years old and have a bank account or taken out a loan, credit card or mobile phone contract, you’ll probably have a credit report. Credit reports are used for many reasons, such as responsible lending, anti-money laundering and fraud prevention. It’s important to check your credit report regularly to monitor your financial health. TransUnion is one of the main credit reference agencies (CRAs) in the UK. It collects and stores information to produce credit reports in the UK.
