If you want to go integrated, you have to pay £60K + for training, no getting around it.
If you don't have that money saved, or can't get a secured loan, or simply cannot stomach the idea of paying £1000 per month for 5 to 10+ years, then go modular.
Same theory, same planes, similar training, same exams and same qualifications, but just more flexible and cheaper! Modular will allow you to work and save and keep your debt low or non existent. And airlines don't really care if your modular or integrated. Their concern is:
Can you fly?
Are you typed, current and how many hours you have?
Can you be trusted in a bad situation?
Are you a team player?
Are you reliable?
Are you the type of person I'd want to sit next to for 6-10 hours a day?
Do a financial plan like if you were starting a business, and in the end, if you realise you cannot afford £1,000 per month on top of rent, car-travel expenses, bills, food and socialising, then forget the integrated route!
Good luck!
