I agree the modular route will cost less than an integrated course.
If you think of the modules as
PPL, Night
Hour building (150hrs)(cheaper abroard)
ATPLs
CPL
IR
MCC
Then it should cost around £25k to £30k if done in the UK with first time passes.
You need to account for loss of income as well as food and accommodation.
BUT spread over 3 years it is easier for the bank to digest than a straight forward £60k
Good Luck
