This website provides result data for the general elections for 2015, 2017 and 2019.
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 upcoming constituency boundaries.
Result data for the upcoming general election will be added once they are known. References to an upcoming general election mean a general election happening in 2024 or later.
By-election results for the 56th, 57th and 58th Parliaments will be added - after which we intend to add both historic by-election and general election results.
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.
Parliament periods are described back to the first Parliament of the United Kingdom, 22nd January 1801.
