How will the Banks judge me?
Lenders use something called Credit History or Credit Rating in order to decide whether to agree to loans with potential borrowers. It is quite simply the history a borrower has in many different financial dealings. Any loans from the past, dealings with phone and energy companies and even the way you pay off credit cards can be included.
What data about me is shared and why?
Data is collected from creditors by one of three main Credit Reference Agencies (CRA), Experian, Equifax and Callcredit. There are thousands of different credit bureaus that get credit information on you directly from your creditors, but most of them come under the umbrella of one of these main three and report all the information they collect to them.
When you apply to a credit card company, such as a bank, they will gather your personal data off you and request all the information the credit bureaus have on you. They then use this to decide whether or not to lend you money. If they do, they then supply the CRA with data on how you pay the repayments in the future, further building your credit history.
