List of United Kingdom by-elections (1900–1918)

This is a list of parliamentary by-elections in the United Kingdom held between 1900 and 1918, with the names of the incumbent and victor and their respective parties. Where seats changed political party at the election, the result is highlighted: pink for a Labour gain, light blue for a Conservative (including Liberal Unionist and Irish Unionist) gain, orange for a Liberal (including Liberal-Labour) gain, green for a Sinn Féin gain, light green for an Irish Parliamentary Party gain and grey for any other gain.

Resignations

:See Resignation from the British House of Commons for more details.

Where the cause of by-election is given as "resignation" or "seeks re-election", this indicates that the incumbent was appointed on his own request to an "office of profit under the Crown", either the Steward of the Chiltern Hundreds or the Steward of the Manor of Northstead. These appointments are made as a constitutional device for leaving the House of Commons, whose Members are not permitted to resign. Members seeking re-election must therefore resign from the "office of profit" before the result of the by-election is returned.
