House of Commons Procedure and Practice, page 588, chapter 12, “Points of Order and Questions of Privilege”, states:
Although the Standing Orders do not expressly forbid the raising of points of order and questions of privilege during divisions, the general practice has been to proceed with the vote and to hear its result before bringing forward any points of order or questions of privilege. There have been occasions when Members have attempted to bring some matter to the attention of the Speaker in the course of a vote (after the Members have been called in and before the result is declared), and the Chair has declined to interrupt the voting process in favour of hearing the point of order or question of privilege. More recently, however, points of order related to the recording of the vote were heard and addressed during the voting process. Immediately after the announcement of the result of a vote, Members who were unable to be in the Chamber for a vote sometimes rise on a point of order to explain how they would have voted had they been present.
