Modular route
+1 for modular route. You work as you learn and see how the market goes. Some say that there will be a shortage of pilots within 2-3 years so you could be good on timing.
As a trainer, I am having increasing difficulty in looking at would-be pilots and their parents in the eye and talking enthusiastically about it.
IF you got through the modular route for around £45k (that is IF) to CPL/IR level plsu CRM, you might then have to pay for a type rating before getting a job. IF you then were to get in as FO with one of the low-quality carriers (Ezy, Flybe, hopefully not with the mad Irishman) you might be earning £25k with debts of £50k. And that's best case scenario!
