Supply Estimates are the means by which the government seeks authority from Parliament for its own spending each year1. The Main Estimates start this process and are presented to Parliament by the Treasury at around the start of the financial year to which they relate. The main Supply Estimates are contained in separate volumes covering the main central government departments, as well as other state bodies such as the House of Commons Administration, the Supreme Court, the National Audit Office, the Electoral Commission, and the National Archives2.

Departmental Estimates include not only the spending plans of the relevant government department
