The Cabinet Office is a department of His Majesty's Government responsible for supporting the prime minister and Cabinet. [3] It is composed of various units that support Cabinet committees and which co-ordinate the delivery of government objectives via other departments. As of December 2021, it has over 10,200 staff, most of whom are civil servants, some of whom work in Whitehall. Staff working in the Prime Minister's Office are part of the Cabinet Office.



The Cabinet Office's core functions are: [4]

The Cabinet Office has responsibility for the following at a 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]


The department was formed in December 1916 from the secretariat of the Committee of Imperial Defence [10] 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.

The entrance to the Cabinet Office.

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.

At around £290 billion every year, public sector procurement accounts for around a third of all public expenditure in the UK. EU-based laws continue to apply to government procurement: procurement is governed by the Public Contracts Regulations 2015, Part 3 of the Small Business, Enterprise and Employment Act 2015, and the Public Contracts (Scotland) Regulations of 2015 and 2016. These regulations implement EU law, which applied in the UK prior to Brexit, and also contain rules known as the "Lord Young Rules" promoting access for small and medium enterprise (SMEs) to public sector contracts, based on Lord Young's Review Growing Your Business, published in 2013. In November 2016 an advisory panel of 24 entrepreneurs and business figures was formed to advise the government on purchasing goods and services from SMEs, and a campaign was launched to demonstrate that "government is open for business", with a target of increasing government spending with SMEs to 33% of all third-party public expenditure by 2020.
