This website provides result data for the general elections of 2010, 2015, 2017, 2019 and 2024 and by-elections taking place since the 2015 general election. That is, during the 56th, 57th, 58th and 59th Parliaments.

By-election results for the 55th Parliament will be added next - after which we intend to add both historic general election and by-election results.

It also provides predicted or ‘notional’ results of the 2019 general election. These results are shown as if that election had been held according to the 2024 constituency boundaries.

Our boundary set information dates back to 26th November 1918. The legislation establishing these boundaries is complete, back to the Representation of the People Act 1918.
