These three units were based permanently at Chelsea Barracks in London on public duties until Chelsea Barracks was sold off by the army. They represent the suspended battalions at significant events, such as Trooping the Colour, and receive the battalion's new colours whenever they are presented. As such, each company is an independent unit of their regiment, separate from the operational battalions. In 2010, with the closure of Chelsea Barracks, the three companies were moved and are now permanently based at Wellington Barracks. A large majority of new guardsmen completing the Combat Infantry Course at the Infantry Training Centre and going to either the Grenadier, Coldstream or Scots Guards will be sent first to the incremental company for between six and nine months, where they will be able to receive further training before they are then posted to the regiment's operational battalion.
