What Is Credit Rating? Explain Credit Rating Systems.

A credit rating is a score that companies can use to test how credit worthy you are.  This means they are able to see if you have used your credit responsibility in the past.  That means other companies who give credit report back on whether you pay your bills on time or at all, to a central credit reference agency, Experian and Equifax are large reference agencies in the UK and the USA.

There is no such thing as a blacklist or an individual score, although scores are produced, it's usually a combination of the requirements of the credit giving company along with a score

A payment is recorded as an O, and a late payment gets the number of payments missed 1-.

People without credit find it hard to get credit and get very upset when denied credit.  People with houses find it easier to get credit. People on the voters roll also find it easier to get credit.
