We consider a symmetric group acting on a set whose  point stabilisers are products of smaller symmetric group (more precisely Young subgroups). The corresponding permutation module is called a Young permutation module. Familiar examples such as  group algebras of symmetric groups, Schur algebras, and partition algebras in positive characteristic arise as endomorphism algebras of Young permutation modules. We describe a general principle from which the distribution of the simple modules into  blocks in these cases may be deduced.  We treat the quantised version throughout.
