The Defence Communication Services Agency (DCSA) was an agency of the United Kingdom Ministry of Defence responsible for the procurement and delivery of Communications and Information Services (CIS) to the defence community and related public and private sector bodies. The Agency was formed on 1 April 1998, bringing together a range of CIS organisations across all three services.

Formally a component of the Defence Logistics Organisation, the Agency brigaded together elements of the Defence Procurement Agency, the DLO and operational support elements within the three military Front Line Commands.[1]

On 31 March 2007 the Agency was subsumed into Defence Equipment & Support, a new organisation bringing together the DPA and DLO, as the Information Systems & Services (ISS) cluster within that organisation.[2]


The DCSA was formed of a core headquarters, led by a military Chief Executive at Two-star rank, supported by an Operations Directorate, Directorate of Engineering and Interoperability, and a number of Integrated Project Teams, responsible for the procurement and support of systems and services. The Agency was headquartered at Basil Hill Barracks, Corsham, Wiltshire,[3] and had 5,000 staff at facilities in many locations in the UK and overseas.[4]
