There is no such thing as a black list.
The credit references hold data on individuals' credit dealings and supply that data to any firms that may be considering giving a person credit. The firms then apply their own processes to the data to decide if they want to lend you money. The system is generally a scoring matrix based on previious credit, employment status, location etc.
Generally an address alone would not form a credit record, it needs the combination of address and the person, that is why they ask for previous addresses when you have lived somewhere for a short time. If you are getting refused credit and don't know why you can ask the credit agencies for the data they hold on you and then you can check the accuracy of it's contents and if necessary demand correction.
Are you sure your credit record is clean?
