A list of those Ministry of Defence establishments at which helicopter flight simulators are based is provided below. For the purposes of this answer, I have interpreted helicopter simulation facilities to mean only full-motion flight simulators.

Name of Establishment
Royal Navy and Army
1 - A generic flight simulator that can be configured to represent a helicopter.
