Get working to save up £40,000
Either that, or pop down to the bank, preferably HSBC, with a gun and a stocking over your head. Maybe not.
Don't forget though that you can get the CDL (career development loan) from various providers, one being Barclays. They will loan up to £8000 with conditions more favorable than a standard loan.
Not quite £40K, but its £8K less saving to do
