In addition to being a church used by a number of regiments and corps of the British army; a church for Church of Scotland and presbyterian members of the armed forces, both current and retired; and a local church for those in Aldershot, the church also draws many of its congregation from non-military people who come from various parts of North Hampshire and West Surrey for the Church of Scotland style service.
There is a crèche room with toys for young children.
St Andrew’s is also a place of remembrance. The church was built in the 1920s, with money raised by fundraising, to the Glory of God and as a memorial in remembrance of soldiers of the Church of Scotland and kindred churches who lost their lives in the First World War. Within the church building there are a number of individual memorials.
