There is a thread on HSBC already. I'm still having no luck with them at all.
As for the Co-Op they approved my CDL for £8000 a few weeks ago - shame the college suspended operations due to near bankruptcy! Mine is on hold with them at the moment until I find out what's happening with the college.
My experience may have made them more wary. Camelsnail, which flying school are you wanting to go to?
