A lot of people will suffer from some form of poor credit during this recession, which remember was caused primarily by the banks, and I think it is unfair to penalise people for such a large proportion of their working life for problems they suffer which are out of their control.
I think that the time that information relating to debt which is recorded on your credit file should be deleted after 3 years and not 6 years, which is the present situation.
This would mean that information such as defaults, CCJ's, Insolvency, missed payments etc would drop of your credit file after 3 years.
