i was under the impression (in the UK at least) that no bank or financial institution was allowed to give an unsecured loan for more than £25,000 so i am guessing that these loans are secured against something!!! banks will not lend that sort of money without equity , collateral or a seriously good wage coming in or a signature of someone ie. a family member/parent countersigning the loan.
Under the old system (which was withdrawn about a year ago) HSBC lent a total of £75000 unsecured to all those accepted onto the Wings Scheme.
