Principal photography took place in the UK, covering both bustling London and picturesque Surrey. Filming began in October 2013 in Deepcut, Surrey. The realism of Eggsy's urban life was achieved by shooting at the Alexandra Road housing estate in Camden. Some scenes related to training and spy technology were filmed within the walls of Imperial College London. The famous pub fight scene involving Harry Hart took place at the real-life pub The Black Prince in Kennington, South London. And to create the impressive facade of the Kingsman headquarters, disguised as a tailor shop, 12 Savile Row was chosen, home to H. Huntsman & Sons. Another notable location is the hat shop James Lock & Co.
Director Matthew Vaughn saved on international filming by making maximum use of computer graphics, as well as the soundstages and grounds of Warner Bros. Studios in Leavesden, near London.

Filming Locations:

Police Station

In the Movie

Scene where Eggsy gets into another fight and ends up in a police station. The investigator offers him to rat out his accomplices or go to jail. In despair over his family situation, Eggsy decides to use a clue he received as a child and calls the number on his father's medal of valor. This call gets him released. Later, Harry Hart scolds Eggsy in a pub for wasting his talent.

In Reality

The scene was filmed at Holborn Police Station. This active police station, located near Chancery Lane tube station, was ideal for creating an authentic atmosphere. The choice of Holborn Police Station as the filming location added realism to the scene where Eggsy, while in custody, uses a code phrase to contact Harry Hart and avoid prison. Using a real police station rather than a set allowed director Matthew Vaughn to create a more convincing and believable environment for this key scene in Eggsy's character development.

Hat Shop

In the Movie

Scene where Richmond Valentine visits the hat shop James Lock & Co., located on St. James's Street. After Valentine admires the elegant smoking jacket worn by Harry Hart, the latter suggests he visit Lock & Co. Hatters. Harry takes Eggsy to the shop, where they are unexpectedly visited by Valentine and his assistant Gazelle. Valentine explains his visit by saying he liked Harry's tuxedo and, since he is going to Royal Ascot, he needs appropriate attire.

In Reality

The scene was filmed at the hat shop James Lock & Co. The shop was ideal for the film for several reasons. First, it is the oldest hat shop in the world with a rich history, founded in 1676. Its connection to the British elite and traditions perfectly suits the image of the secret Kingsman organization disguised as a high-fashion tailor shop. Second, the building itself is a historical landmark, adding authenticity and visual appeal to the film. Finally, James Lock & Co. indeed opened its doors for filming, making the scene where Samuel L. Jackson exits the shop in a silk top hat more realistic and convincing. Using a real shop rather than a set allowed director Matthew Vaughn to create a sense of immersion in the world of Kingsman.

Church

In the Movie

Scene where Galahad goes to a church in Kentucky to investigate how Valentine is spreading his aggression-inducing signal. Valentine tests his new weapon by broadcasting a signal that makes everyone in the church, including Harry, uncontrollably aggressive and violent. Under the influence of the signal, Harry begins killing all the parishioners, including women and children, in a bloody and choreographed massacre. The scene stands out for its brutality, unexpectedness, and how it shows even an experienced agent like Galahad losing control.

In Reality

The scene was filmed at St Barbara's Community Church in Deepcut. This church provided the director and crew with the necessary space and atmosphere to create the tense and shocking scene. The choice of this particular church may have been due to its relatively small size and simple architecture, which helped create a sense of claustrophobia and vulnerability during the filming of the mass violence scene. Additionally, the church's location in a quiet, remote area may have facilitated filming logistics and provided the necessary privacy for such a sensitive scene.
