The United Kingdom Space Agency (or UK Space Agency) was a British agency responsible for the country's space programme.

The National Foundation for Scientific Research secretly worked with the Space Agency, producing an alloy from elements supplied by them. (AUDIO: Catch-1782)

In the 2010s, the UK Space Agency collaborated with UNIT in the building of the Starseeker, but used alien technology without their knowledge. A conference was held, attended by Kate Stewart, Jimmy Tan and Hasper, during which the Starseeker's drive exploded. (AUDIO: The Man From Gallifrey)
