History
Alistair Gordon Lethbridge-Stewart reported to them during the Cyberman invasion in the late 20th century (TV: The Invasion) and threatened to contact them other times.

When a Third World War seemed inevitable, Central Control sent an alert to all UNIT national headquarter, informing them of the global situation and telling them to go on high alert. (TV: Day of the Daleks)

In the 1970s, Captain James Munro worked at UNIT Central Control. (PROSE: The Devil Goblins from Neptune)

In 2008, UNIT Central witnessed the assassination of American President Arthur Coleman Winters aboard the aircraft carrier Valiant by a Toclafane acting on the orders of British Prime Minister Harold Saxon, actually. After the Year That Never Was was reversed, a transmission from UNIT Central, asking for clarification, was heard but not answered aboard the flight deck within the Valiant. (TV: The Sound of Drums/Last of the Time Lords)

In 2009, UNIT Central Control declared its highest alert in the face of a Dalek invasion of Earth. (TV: The Stolen Earth)

In 2019, UNIT Central objected to a UFO being shot down over Wasdale Head. However, two Typhoons from the Quick Reaction Alert Station at RAF Lossiemouth were ordered to intercept it, leading to Dorothy McShane salvaging the escape pod.

Behind the scenes
In The Van Statten Code, a puzzle-game in Doctor Who Annual 2006 not considered a valid source due to casting the reader as a character in the Doctor Who universe, "UNIT Headquarters in Geneva" receive a short message in Van Statten Code warning them to "beware the Bad Wolf".
