    Let H be a Hilbert space, \({\mathcal A}^ a \)subalgebra and J a two-sided ideal of \({\mathcal B}(H)\). Put C(\({\mathcal A},J)=\{T\in {\mathcal B}(H):AT-TA\in J\) for every \(A\in {\mathcal A}\}\). It is proved that if \({\mathcal A}\) is a nest algebra, then always C(\({\mathcal A},J)=\{C\cdot I\}+J\).
