Hi money_man,
By 'arrangements' I mean have you had your credit file searched and committed yourself and entered into an agreement? If you don't have much on credit, you don't really have a credit file as such.
By 'searches' this means when you apply for something, and subsequently get turned down (or even accepted) this is a 'search'. Recruitment agencies, employers, banks, even insurance companies make searches but this should always be advised if not obvious! If you have lots of searches applied to you, then this can count against you.
And when I mentioned about me not being in double figures, I meant I probably have a credit rating between 1 and 9 - not over 10!!!
