Dept. Q Season 2 is not coming in April 2026.
Dept. Q Season 1 came out on Netflix May 29th, 2025, and was renewed for season two in August 2025, featuring Matthew Goode as DCI Carl Morck. However, the new season will not start filming until July 2026 (on July 13th), in Edinburgh, Scotland, and wrap no later than December 2026.
Because of the need for the entire post-production process, including editing, etc., plus Netflix’s normal release schedule, an early 2026 debut is very unlikely. Based on solid sources, a 2027 debut will be much more likely, possibly towards the second half or as soon as early 2028. Early rumours cited that filming would possibly begin sometime in Spring or April of 2026; however, this has since been corrected to be later in the July through December timeframe.
Season 2 is certainly going ahead, but you will probably have to wait until at least 2027 for it to arrive. Netflix has not yet provided any additional information about specific premiere dates.
