Permission was obtained to film at an empty office and a bar in Slough. At the office, emergency exits were identified and the lighting could be adjusted as needed. A test was done beforehand and no sound or video issues were found. Filming details were confirmed with the crew. At the bar, areas inside and outside were checked for safety and the owner was aware of the filming. Most filming would be indoors or at night, and the crew had parking permission. Photos were taken of the locations beforehand to plan shots and avoid issues later.
