Factual error: The action takes place around the second half of June (either side of the Glastonbury festival weekend). At the beginning of the film leaving work early evening in time to get home for dinner, in the UK, it wouldn't be dark. Later on, there isn't that much snow in the Alps, especially below the tree line, at that time of year.
Other mistake: At the beginning, as Eggsy is pursued through city streets by the Golden Circle henchmen, the three pursuit vehicles are all firing rooftop mini-guns at Eggsy, in spite of the fact that they are all in single-file, one vehicle behind another. The Golden Circle vehicles would have been riddled with their own gunfire.
