that table there by UK CAA may not be honoured outside UK.
It's also 'pre-approved training times' and it can be reduced on individual basis. They did this to avoid being clogged up by individual requests with ATO recommending shorter course/syllabus etc.
The IR conversion stays as 15hrs min without needing further reduction approval. CPL discussed. It can be 5 or 10 hours, really, depending on recommendation of ATO and that approved by CAA under which one would do LST (flight test, holding medical records etc).
Same with commercial. It's grossly general guidance and depends on piloting skills, familiarity with airspace, aircraft to train on, currency. So obviously don't go by the numbers only, or read the whole CAP portion or guide dealing with this. Can't find it right now - bookmark on another computer, but UK CAA as source.
BTW, you can do checkride shopping, don't have to pay hefty CPL skills test fees if you decide to do some training elsewhere, but the examiner needs to do briefing and possibly notify NAA with your training records before the actual flight test, depending on NAA.
