It's probably cut,
This review is from: Halloween 1-5 Collection [DVD] (DVD)
Listings at the BBFC site indicate Anchor Bay have not had these films re-certified. This suggests this set is simply a re-release of their earlier Halloween Collection and in that case Halloween III: Season of the Witch will still have cuts.
A collection of all six films, uncut, would get five stars from me! But it looks like it will never happen.
