I was speaking to a someone who had completed a cadet programme a couple of years back and they said that other cadets should consider getting their parents to go for a straight remortgage of the house to pay the fees up front, rather than the BBVA scheme, since the latter was often more expensive in terms of interest rates.
How the banks and building societies affected would respond I don't know but I wouldn't be surprised if they cottoned on quickly, especially if the aviation industry suffered a downturn.
