The Government Communications Headquarters (GCHQ) was, according to the Thirteenth Doctor, the biggest communications resource in the United Kingdom. (TV: Resolution) It was based in a building in Cheltenham that was shaped like a bagel. (AUDIO: Iceberg)
Major Harry York worked at the GCHQ by 2005. (PROSE: UNIT Conferences)
On 1 January 2019, a Reconnaisance Dalek penetrated the GCHQ and commandeered its resources in an attempt to contact the Dalek invasion fleet, but was stopped by the Thirteenth Doctor and Team TARDIS. (TV: Resolution) In the aftermath of the Recon Scout Incident, the Dalek's melted casing was removed from the scene. (TV: Revolution of the Daleks)
In early 2020, the Doctor suggested that C, head of MI6, ask his "mates" at GCHQ should he doubt the existence of extraterrestrial life. (TV: Spyfall)
When Liv Chenka engaged in computer hacking to get official records on a recently crashed spaceship in the 2020s, Tania Bell joked that GCHQ would send the "spy police" to imprison her. Coming from Kaldor, Liv confused them with Robin Bright-Thompson's GCSEs. (AUDIO: The Chaos Cascade)
