We study uniform perturbations of intermediate C ∗ ‐subalgebras of inclusions of simple C ∗ ‐algebras. If a unital simple C ∗ ‐algebra has a simple C ∗ ‐subalgebra of finite index, then sufficiently close intermediate C ∗ ‐subalgebras are unitarily equivalent. These intermediate C ∗ ‐subalgebras need not be nuclear. The unitary can be chosen in the relative commutant algebra. An immediate corollary is the following: If the relative commutant is trivial, then the set of intermediate C ∗ ‐subalgebras is a finite set.
