Hi glueless,
The HSBC loan is a UK-government backed Career Development Loan so you need to be a UK resident to qualify as far as I am aware.
If you speak to Mary-Jo Sanchez at Jerez, there was talk a few months ago of a finance deal with Ulster Bank at Dublin Airport - I don't have the details to hand but she did give me a name to speak to at that branch. If the possibility is still there, I'm sure she'd gladly give you the contact name. You may need to go down to Jerez for their aptitude tests first though, which I believe are free at present - only cost is Ryanair to Jerez via Stansted.
Another alternative to the big integrated schools would be Pilot Training College in Waterford. They've recently sorted out a deal with a local AIB branch so I'd have a word with Darragh Owens down there. As far as I'm aware, the deal includes deferred repayments until a few months after training is completed. PTC may not have the same reputation as one of the Big Three (Jerez, Oxford, Cabair) but their success rate with getting graduates into jobs seems fairly healthy to me. Your costs would be significantly lower too if you go full-time modular rather than integrated - about €60k in PTC. But beware, in all cases those costs are based on minimum hours to completion. You'll need a slush fund to pay for extra training required, rising fuel costs etc.
Let us know how you get on, I'm currently finishing up my PPL then I'll be getting down to work with my ATPL exams - after that I'll be running to the bank manager for more money so any tips would be welcome! Who knows, we may share a flight deck some day!
Best of luck whatever you decide,
Conor
