In answer to James and any others asking, once on a permanent contract you will have the bond repaid to you, at the rate of £1000 a month. However as your salary is £1000 a month less than a direct entry salary the only benefit you see is a slight advantage in your tax liability, which is nothing to be sniffed at, but still, it's not a repayment in the grand scheme of things.
Consider that £69000 gone, (it's paying for your training) and you won't be far wrong
