Although the United Kingdom of Great Britain and Ireland was created in 1801, it was not until the Consolidated Fund Act 1816 that the separate offices of 'Lord High Treasurer of Great Britain' and Lord High Treasurer of Ireland were united into one office as the 'Lord High Treasurer of the United Kingdom of Great Britain and Ireland' on 5 January 1817. The office continued in commission and the commissioners of the old office of 'Lord High Treasurer of Great Britain' continued as the commissioners of the new combined office.
