This is a complete list of Acts of the Parliament of the United Kingdom for the year 1945. Note that the first parliament of the United Kingdom was held in 1801; parliaments between 1707 and 1800 were either parliaments of Great Britain or of Ireland. For Acts passed up until 1707 see List of Acts of the Parliament of England and List of Acts of the Parliament of Scotland. For Acts passed from 1707 to 1800 see List of Acts of the Parliament of Great Britain. See also the List of Acts of the Parliament of Ireland.
For Acts of the devolved parliaments and assemblies in the United Kingdom, see the List of Acts of the Scottish Parliament, the List of Acts of the Northern Ireland Assembly, and the List of Acts and Measures of Senedd Cymru; see also the List of Acts of the Parliament of Northern Ireland.
The number shown after each Act's title is its chapter number. Acts passed before 1963 are cited using this number, preceded by the year(s) of the reign during which the relevant parliamentary session was held; thus the Union with Ireland Act 1800 is cited as "39 & 40 Geo. 3 c. 67", meaning the 67th Act passed during the session that started in the 39th year of the reign of George III and which finished in the 40th year of that reign. Note that the modern convention is to use Arabic numerals in citations (thus "41 Geo. 3" rather than "41 Geo. III"). cts of the last session of the Parliament of Great Britain and the first session of the Parliament of the United Kingdom are both cited as "41 Geo. 3". Acts passed from 1963 onwards are simply cited by calendar year and chapter number.
8 & 9 Geo. 6
Continuing the tenth session of the 37th Parliament of the United Kingdom, which met from 29 November 1944 until 15 June 1945.
