The CHF were told to move into JHC by VCDS.
There is a real question as to whether JHC represents value for money. It certainly didn't for the RN as it required a large uplift in HQ staff officers (something like from 2 up to 12). The main benefit is that it has given the Junglies a better career path than they had before, otherwise they would probably be better off in Fleet HQ.
More controversially one could make an argument that they have had to meet the lowest common denominator in terms of standards. I will not name the guilty Service but I think we know who I mean.
