Stars in the post‐asymptotic giant branch (post‐AGB) phase of evolution are surrounded by detached circumstellar envelopes containing dust which emits thermally in the mid‐ and far‐infrared. Here we present 850‐μm SCUBA photometry of nine candidate post‐AGB stars. All targets are detected at 850 μm and we use these fluxes to estimate the envelope dust masses and, by comparison with the 100‐μm IRAS fluxes, the dust emissivity index.
