The Civil Service Order in Council 1995 gives the Minister for the Civil Service the power to make regulations and give instructions for the management of the Home Civil Service. The Civil Service Management Code then sets out regulations and instructions to departments and agencies regarding the terms and conditions of service of civil servants. It also sets out the delegations that have been made by the Minister for the Civil Service and any conditions attached to those delegations.
In relation to the Senior Civil Service, a number of terms and conditions of service are set and managed centrally so come under the authority of the Minister of the Civil Service, administered by the Cabinet Office. The delegated terms and conditions of service come under the authority of the individual to whom they have been delegated. In relation to civil servants supporting the Scottish Government, who are members of the unified Home Civil Service, this would be the First Minister, administered by the Scottish Government.
The Civil Service Management Code, which sets out which terms and conditions are centrally set and managed centrally and which are delegated, is available at http://www.civilservice.gov.uk/about/resources/csmc /index.aspx.
