Data for historical UK By Elections is not, insofar as I am aware, available on any government website. The author has scraped this data from Wikipedia pages.

In some cases, the data has clear inconsistencies, especially around variant spellings of the names of constituencies and political parties. I have attempted to remove these insofar as possible. Votes for small parties and independent candidates are unfortunately often not recorded.

Where turnout figures are marked as "estimated", this means that I have been unable to find a figure online. I have estimated the turnout by adding up the number of votes cast for each candidate, meaning that these figures will not include spoiled ballots.

On this website, the term "swing" is used to refer to a hypothetical transfer of vote share from the party which saw the greatest loss of vote share, towards the party which made the greatest gain in vote share. In simple elections with two dominant candidates, this may reflect a genuine transfer of votes from one party to another. In more complicated elections, it may not give a full picture.
