Zero to CPL/IR + MCC was about £45k all in, including medicals, exams, CPL retest, accomodation where necessary and various overpriced bits of plastic.
It took me nearly seven years, but it's a very long story (see below for the gory details). Could be done inside 18 months if you really wanted to, but you'd be mad to rush at the moment. Three to four years would be more sensible.
