Si, A CDL will only supply you with upto a maximum of £8000 towards your studies (as previously stated HSBC will fund the entire course) and repayments will commence almost immediatly after finishing your studies and the interest will be somewhere between 8-10% (Cant be sure) Another thing is that you can only repay the loan over a maximum of 5 years, whereas with the HSBC you have the choice of 5, 7 or 10 years.
An added bonus with HSBC is that they will cover living expences upto a max of £5000 or 2/3 of your previous years salary which ever is lower! This of course will be added to the loan. (You never get anything for free, especially from a bank)
