For a simple answer, fhchiang, yes it would be cheaper.
From the same school as might offer integrated, around £10,000 saved when I was looking into this, probably more now. Shop around and it may be more. To do all training from zero in the UK can be as little as £40,000, realistically and with all CAA fees, landing fees and VAT included (watch that, some include VAT and landing fees, some don't). You also have a choice to change provider between modules if you are not happy, and don't have to pay upfront (I have friends who lost over £14,000 that way. I lost nearly £3,000).
Be sure to visit a variety of schools, look at training material, ask students about the course (and the training materials - some are told by their instructors not to use the manuals as they are inadequate). Talk to staff, see if you could be happy in that town, in that school.
Good luck!
