The Accumulated Campaign Service Medal is currently awarded to those who have completed 1,080 days, aggregated by 1 January 2008, in theatres which would have merited a General Service Medal 1962 (e.g. for operations in Northern Ireland or air operations in Iraq), an Operational Service Medal for Afghanistan, an Operational Service Medal for Sierra Leone or an Iraq Medal.

The criteria for the medal was substantially revised in 2011. The qualifying period was reduced from 1,080 to 720 days, the medal was retitled the 'Accumulated Campaign Service Medal 2011' and the ribbon was redesigned. Qualification for the Accumulated Campaign Service Medal 2011 was also restricted to only those serving from 1 January 2008.

In 2019, the MOD Medal Office paused awarding the ACSM 2011 after concerns were raised that the Ministry of Defence was incorrectly applying the ‘double medaling’ principle to restrict qualification. The MOD initiated a review of the qualifying criteria and the results were made public on 30 July 2021. The review restored the previous less restrictive criteria and also announced that serving and former Service personnel, previously deemed ineligible for the ACSM 2011, can re-apply.
