a UK "CFI" is just a self appointed title for the bloke who runs the flying school)

Page 5 gives further details, (although applies to commercial training.) It is a bit vague regarding qualification criteria but I am pretty sure a recognised CFI has to meet minimum criteria set down by The CAA/JAR. I dont think for example a new recently de-restricted FI could set himself up as a CFI of a new FTO overnight. Doubtless someone on the instructor forum could advise further.
