I think you need to add about £30-35K to the budget to fund your living expenses for 3-3.5 years. Whether you have it up front or work a second job and pay as you go doesn't matter, as that is what you will spend.
You might as well go standard modular or integrated, finish in 1.5 years and hopefully get a job within 12 months and earn £30K in year 2.5 to 3.5.
This company is not even an FTO, just some re-packager with a pretty lame marketing scheme, aka a middleman who takes an additional cut.
