The number of trained UK regular forces service personnel who opted not to extend their service is recorded in tables 1-8 of TSP5 (UK Regular Forces Outflow From Trained Strength to Civil Life) as outflow type “Time Expiry”. Statistics are available for each service and on a tri service basis.
TSP5 is published monthly. The current September 2008 publication includes time series back to 1998/99 and can be found at:
