Two options available:-
1. Career Development Loan.
2. Professional Studies Loan.
Both very similar to student loans i.e. deferred repayments with low interest rates. The CDL is roughly 8k maximum that can be borrowed, but the PSL can usually offer anything up to 50 or 60k(assuming you can secure the loan somehow... i.e against property or similar).
The PSL is the loan that most 'integrated' students apply for through the likes of HSBC, in conjuction with the respective flight training provider.
Both loans will require some form of business plan at the application stage. Unfortunately however it will be a hard job convincing any bank Manager that there are an abundance of Pilot vacancies out there, given the current climate! Best of luck though!
If you google CDL and PSL loans then you should hopefuly find plenty info.
