A 6-episode second series of the dramedy was commissioned in August 2019 and filming on series 2 wrapped in London on 28th October 2019. The UKTV channel "W" in the UK and "Pop TV" in the U.S. announced that the new series would premiere on both channels on 13th March 2020. However, just 1 week before the announced premiere date Pop TV announced that they had "cancelled" Flack. In response UKTV delayed the UK broadcast of series 2. Series 2 will now commence on W in the UK at 10pm on 13th April 2020. The British production company Hat Trick Productions are working with Pop to find a new US distributor for the show. To add to the confusion IMDb has frequently incorrectly linked to the Canadian TV channel "W Network" instead of the British channel "W" in news stories about Flack.
The pilot episode for this series was originally shot in London, with Sheridan Smith playing the lead role.
