CDL was changed to PDL or PCDL or whatever it's called now.
In the past US based schools with UK affiliation were approved for using the funds/loan.
Do not forget that unless you have no other options to get regular loan (??) for some extra spending/cost, if you don't do the course over long period (which is the time when interest covered by UK govt agency), it's not worth it.
The interest rates are higher than regular loans.
Also, it's through commercial banks who assess you just as if you applied for regular loan, so it's not 'guaranteed done deal' to apply for it.
I did consider CDL for Euro FI rating/or part of, rotary, but not anymore. Just not worth paying so much extra in interest.
It could work OK in your case, if you do 2 year course etc, but I'd not want to repay the interest at that rate.
