Will Ye No Come Back Again was recorded in the studio on 1, 7 and 8 August 1975. The location footage was filmed in Applecross in Wester Ross, Scotland, and was filmed from 6 to 9 May. The idea behind part of the plot, regarding poaching, was taken from the 1953 filmLaxdale Hall, which was written and produced by Alfred Shaughnessy, the script editor of Upstairs, Downstairs. The only main cast member needed for the location scenes was Gordon Jackson, who was provided with a double so he was only needed for one day of filming. Despite being the twelfth episode to air, Will Ye No Come Back Again was the last ever episode of Upstairs, Downstairs to be recorded in the studio. The title of the episode is taken from the Scottish Jacobite song Bonnie Charlie written by Lady Nairne.
