My dear friends
You have two ways to do it ,Integrated and Modular.
Integrated pay the big bucks through a recommended school or the modular way which is a lot cheaper, with the modular route you can go to any School you want and are not bonded also you can take out time to work if you have to.
My advice to you would be do your PPL in the Uk and find a school which does your PPL and CPL, also look up schools that do the CPL/IR, you can also hour build here, some Companies do hour building as cheap as 65 pounds an hour, I myself have been through this experience and went to alot of trouble to get to where I am.
CTC in the other hand require an PPL before you apply and they bond you to the company.
ALI 1 is talking about if you have a Frozen ATPL already.
Send me a PM IF you require more info.
