There is no such thing as a black list. It simply means that there are negative data on your credit report that is hosted at a Credit Bureau. This negative data can be anything, from a plain collection on one of your loans right through Judgment data or even Debt review.

This negative data will have an impact on your ability to get loans or open retail accounts as the credit provider will see this negative behaviour towards your current credit as a potential way that you will handle their loan; if granted.

A Credit bureau is an organisation that keeps a record of your credit information. Your credit record shows how you manage your debts and is used by credit providers and moneylenders to decide if you can afford to borrow money or pay back a new loan.

The National Credit Act says each credit bureau must be registered with the National Credit Regulator – who decides how your credit information can be used and who can see your credit record.

What is the role of a Credit Bureau?

When you take out your first loan with a credit provider, you have to fill in a form that asks for consumer credit information – including your credit history, financial history, education, employment and identity details. This information, and the details of the loan, is given to a credit bureau that then puts together credit report.

What are your rights regarding a Credit Bureau?
 

• To be told that a credit provider intends to report negative information on you to a credit bureau 20 working days before they do so
• To get a copy of your credit record from a credit bureau when you ask for it – you can get one free record each year but may be charged a small fee for further records
• To challenge information kept by a credit bureau if you are unhappy with it
• For your information to be kept confidential, and for it to be used only for the purposes that are allowed

How can your credit information be used?
 

• To decide whether or not you can afford credit
• To investigate fraud, corruption or theft
• To consider you for employment in a position that requires trust, honesty and the handling of cash or finances
