Does being on unemployment affect your credit rating?

No. It does not affect your credit history. However, when you apply for a loan, it is constituted as a form of income and a form of "unstable" income. So, if you are currently collecting unemployment, and are interested in applying for a mortgage, you might get declined. Not because of your credit, but because it's considered income.

Another opinion:

Yes it does. Periods of unemployment effect your credit score in a negative way. collecting unemployment clearly put you in the light of creditors as being in that "period on unemployment". See the Related Link below.
