I had a terrible credit rating. When my first husband and I split up we had 2 mortgages, 2 bank loans and a credit card - all of which I defaulted on because I just couldn't afford to pay anything (single mum on £500 per month - no help at all). I did all my banking with one bank though, and my record with them was spotless. They have given me 2 substantial loan and a credit card over the years - no problem.
