The Cabinet Office's core functions are:[4]
The Cabinet Office has responsibility for the following at the UK national level:
UK Government Procurement Policy Notes are issued in the name of the Cabinet Office, although in the past they were issued by the Crown Commercial Service (CCS).[8] The CCS Helpdesk continues to act as the contact point for any queries.[9]
In October 2023 the government announced the establishment of a National Security Unit for Procurement within the Cabinet Office, which
"will work across government, including with our national security community, to investigate suppliers who could pose a risk to national security. The Unit will create a new layer of protection, by assessing whether companies should be struck off from competing to supply goods and services to the public sector where they pose a threat."[10]
The department was formed in December 1916 from the secretariat of the Committee of Imperial Defence[11] under Sir Maurice Hankey, the first Cabinet Secretary.
Traditionally the most important part of the Cabinet Office's role was facilitating collective decision-making by the Cabinet, through running and supporting Cabinet-level committees. This is still its principal role, but since the absorption of some of the functions of the Civil Service Department in 1981 the Cabinet Office has also helped to ensure that a wide range of Ministerial priorities are taken forward across Whitehall.
It also contains miscellaneous units that do not sit well in other departments. For example:
In modern times the Cabinet Office often takes on responsibility for areas of policy which are the priority of the Government of the time. The units that administer these areas migrate in and out of the Cabinet Office as government priorities (and governments) change.

Cabinet committees have two key purposes:[17]
The main building of the Cabinet Office is at 70 Whitehall, adjacent to Downing Street. The building connects three historically distinct properties, as well as the remains of Henry VIII's 1530 tennis courts, part of the Palace of Whitehall, which can be seen within the building. The Whitehall frontage was designed by Sir John Soane and completed by Sir Charles Barry between 1845 and 1847 as the Treasury Buildings. Immediately to the west Dorset House (1700) connects the front of the building to William Kent's Treasury (1733–36), which faces out onto Horse Guards Parade. The latter is built over the site of the Cockpit, used for cock fighting in the Tudor period, and subsequently as a theatre. In the early 1960s the buildings were restored and many of the Tudor remains were exposed and repaired. Significant renovations between 2010 and 2016 converted many of the floors to open plan and created new office space. The Cabinet Office Briefing Rooms are located on this site.
The department occupies other buildings in Whitehall and the surrounding area, including part of 1 Horse Guards, as well as sites in other parts of the country.
