If Σ and Σ′ are homotopic embedded surfaces in a 4‐manifold, then they may be related by a regular homotopy (at the expense of introducing double points) or by a sequence of stabilisations and destabilisations (at the expense of adding genus). This naturally gives rise to two integer‐valued notions of distance between the embeddings: the singularity distance dsing(Σ,Σ′) and the stabilisation distance dst(Σ,Σ′) . Using techniques similar to those used by Gabai in his proof of the 4‐dimensional light bulb theorem, we prove that dst(Σ,Σ′)⩽dsing(Σ,Σ′)+1 .
