If you have a IR, the cpl is only 15 hours.
LASORS 2007
Section D 1.2 (D)
Applicants with a valid JAR-FCL or ICAO
Instrument Rating (Aeroplane) shall be given at
least 15 hours dual visual flight instruction, and
shall be fully credited towards the dual instrument
instruction time. The same credit may be given to
applicants who have completed an IR(A) modular
course of training and passed IR(A) skill test but
who have yet to apply for the issue of the IR(A),
provided the IR(A) course and JAR CPL(A)
modular course are conducted independent of
each other, and that there is no training overlap
between the two courses.
Also have a look at all the "big" modular schools websites, They do it in 15 hours.
