Policy background The role of Her Majesty’s Treasury in NHS funding
The Crown is charged with the management of all the revenue of State, and with all the payments for public service. Departments (as representatives of the Crown) are required to present to Parliament their requirements for the financing of public services, which they do by presenting estimates of their expenditure, known as "Supply Estimates". Parliament will then vote on whether to authorise that expenditure and therefore provide the ways and means to meet it.
	Under a long-standing convention, departmental Supply Estimates must be approved by the Treasury before they are presented to Parliament and must be fully consistent with Treasury budgetary controls.
	Most departments’ Estimates (including DHSC’s) are then presented to Parliament by the Treasury as a single publication(1). The Commons then considers the Estimates put forward by the government and confirms authorisation of the amounts in the Estimates through passing Supply and Appropriation Acts annually which grant the supply of funding from the Consolidated Fund to Departments.
