Returns of Election Expenses
These have been published after every general election from 1868, with the single exception of 1918, and list the names the candidates (or their agents) gave, together with the number of votes. These are assembled from the individual declarations and returns made by each constituency's returning officer. Since 2005, expenses returns have been posted on the Electoral Commission's website. These are not always 100% correct.
F W S Craig / Parliamentary Research Services
Craig published four definitive volumes of British Parliamentary Election Results, 1832-1885, 1885-1918, 1918-1950 and 1950-1974. A supplementary volume containing results between 1974 and 1983 was also published. He also wrote many other reference works relating to parliamentary elections, including summaries, manifestos, constituency boundaries and "Most Gracious Speeches". Craig died in 1989, and his records were passed to Thrasher and Rawlings in Plymouth.
The History of Parliament
The History of Parliament project is a huge project to document the history of every constituency and MP since the late 14th century. The project splits the history into periods - 1386-1421, 1509-58, 1558-1603, 1604-29, 1660-90, 1690-1715, 1715-54, 1754-90, 1790-1820 and 1820-32. Each period has at least one volume detailing election results and giving constituency profiles as well as general political contexts for the period, and then a number of volumes containing biographical information for every MP - not candidates, although it seems that most people who stood for election before the 1820s did get elected at some point. There are still gaps in the historical coverage, but it is complete from 1660. The project has also started working on a set of biographies for all members of the House of Lords from 1604. The project moved online around 2005 - see the Websites section for more information.
Parliamentary Election Results in Ireland, 1801-1922 - B M Walker (Royal Irish Academy, 1978)
This book contains details of all Irish constituencies since 1801. F W S Craig's volumes of election results did not include results from Ireland until partition in 1922, when results from Northern Ireland were included.
Dod's Parliamentary Companions
These annual books give brief biographies of each MP currently elected, and go back to 1832. Somewhat pricy, many public libraries have at least one edition.
The Times Guides to the Commons
Published after each General Election, the Times Guides contain biographical information about most candidates who stood for election.
The Parliamentary History of the Principality of Wales - W R Williams (Brecknock, 1895)
This fascinating book displays its Victorian credentials, and is well-researched for its period. Some of its contents do conflict with other sources, but it holds details of elections from when Wales started to return MPs in the sixteenth century.
The Parliaments of England - Henry Stooks Smith (Simpkin, Marshall & Co, 1844-49)
These books are interesting little volumes, and display the essence of early Victorian record-keeping which can look slightly quirky to modern eyes.
The BBC/ITN Guide to the New Parliamentary Constituencies - Parliamentary Research Services, 1983
This book attempted to project what the 1979 General Election results would have been on the boundaries implemented for the 1983 General Election. It also contained details of which areas the new constituencies comprised, and linked them to the old constituencies. This turned out to be a one-off in terms of detail.
Boundary Commission Reports
The Boundary Commissions - there are separate ones for England, Scotland, Wales and Northern Ireland - report periodically with recommendations for new boundaries for parliamentary constituencies. Reviews were carried out and implemented in 1947 (First Review), 1969 (Second Review - not implemented until the February 1974 general election), 1982 (Third Review), 1994 (Fourth Review), 2007 (Fifth Review) and 2023 (Eighth Review). Each review details the geographical contents and boundaries of the recommended constituencies, with later reviews also including electorates. The Sixth Review of 2011 was cancelled in 2013, and the subsequent review of 2018 was also not implemented. Reviews from 2011 are online.
