Electors have just three hours to place their votes for the Coombe Vale double byelection.
Polling stations across the ward opened at 7am this morning and will shut at 10pm.
The eleven candidates have been busy campaigning and are looking forward to a result in the early hours of Friday morning.
Coombe Vale ward lies in the Richmond Park constituency and has elected three Conservative councillors at the last two local elections.
Last year the bottom-placed Conservative was only 79 votes ahead of top placed Liberal Democrat candidate Julie Haines, while the ward was split between two Lib Dems and one Conservative in 2002.
The double byelection follows the resignation of councillors Robert-John Tasker and James White in October and November this year.
