UK Swingometer

This page contains the general election swingometer used to predict election results for the next general election as well as a collection of historical swingometers. This UK election seat calculator will calculate its results on a uniform swing relative to the specified election.

To get an idea of the most recent polling figures, we maintain lists of the latest UK election polls.

Note: The United Kingdom swingometer uses percentages for Great Britain, but takes the seats in Northern Ireland into account (as opposition seats) when calculating the majority.
