United Kingdom general election records
Prior to 1945, electoral competition in the United Kingdom exhibited features which make meaningful comparisons with modern results difficult.
Among the most significant were:-
- Frequent interventions and withdrawals of parties in different seats.
- Frequent Coalitions between parties, splits within parties and floor-crossing by members.
- Uncontested elections and truces between parties, in particular during both World Wars.
- Generally more significant competition from independent candidates and minor parties.
- Multi-member seats and University seats.
- Higher frequency of general elections, although parliaments were extended during both World Wars.
- Generally higher turnouts.
- Generally higher variation in size of constituency electorates.
Since 1945, the evolution of a stable 3-party system has tended to negate each of the above features so that, broadly speaking, elections are more comparable.
In Northern Ireland, as ever, the pattern of party competition is completely different from that in Great Britain and comparisons remain problematic.
Hence, unless otherwise stated records are based on results since the 1945 General Election, and earlier exceptional results are listed separately.

For comparison purposes the following definitions have been adopted.
- Gain - victory by a party which was not victorious at the immediate previous election.
- Loss - defeat of a party which was victorious at the immediate previous election.
- Hold - victory by a party which was victorious at the immediate previous election.
- Win - victory by a party. Ambiguous term that could mean either a gain or a hold.
- Incumbent - the party which held the seat at the immediate previous election, irrespective of any intervening change of candidate or candidate's change of party.
- Third Party - In England, since 1922, the "third party" has been the Liberal party through its Alliance with the SDP and their successors up to the present day Liberal Democrats. Additionally, in Scotland and Wales the Scottish National Party and Plaid Cymru are also considered to be Third Parties. Prior to 1922, the third party was the Labour party.
- Minor Party - parties smaller than the Third Party
- Uncontested - an election where only one candidate is put forward. No votes are actually cast and the candidate is by definition the victor.
- Notional - boundary changes occur about every 10–15 years. Invariably the political composition of many seats is changed as a result, sometimes decisively. Professors Colin Rallings and Michael Thrasher have compiled notional results for the last few sets of boundary changes, predicting what the result would have been at the previous election under the new boundaries. While accurate overall, the results in a few seats indicate that they may have been mistaken.

National two-party swings
- 1945 general election – 11.8% swing from Conservative/National Liberal to Labour
- 1931 general election – 14.4% swing from Labour to National Government:20

- Hemel Hempstead, 2010 – 14.4% (Conservative hold)
- Cannock Chase, 2010 – 14.0% (Conservative gain; swing based on estimated previous vote share)
From Labour to SNP
A party's share of the vote at a general election is not always matched at subsequent general elections, but given the five-year maximum term of a Parliament since 1911, reductions of 20% or more are unusual.
- 2015 General Election – Liberal Democrats: −15.1%
- 1945 General Election – Conservatives: −11.6%
- 1997 General Election – Conservatives: −11.2%
- 2017 General Election – UKIP: −10.8%
- 1983 General Election – Labour: −9.3%
- 1929 General Election – Conservatives: −8.7%
- February 1974 General Election - Conservatives: −8.5%
These records detail the change in the share of the vote by parties when compared to the same constituency in the previous General Election. In some cases, such as Brent East in 2005 for the Liberal Democrats, the figures should be framed by the context of a by-election in that constituency between the two Elections.

Largest number of votes
The most votes received by a single individual in a general election was Sir Cooper Rawson who polled 75,205 votes when being reelected as MP for Brighton in 1931. Brighton was a two-member constituency with a larger than average electorate. The most votes received by an individual in a single-seat constituency was 69,762 for Reginald Blair in Hendon in 1935.:101
The largest majority received by an individual is also Sir Cooper Rawson, reelected with a majority of 62,253 at Brighton in 1931.:101 The largest majority received by a woman is 38,823 by the Countess of Iveagh elected MP for Southend in 1931.
All general election victors receiving less than 33.33% of the vote are listed. The list is complete from 1945 onwards. Seats with more than one member are omitted.

Highest turnouts in any general election since 1918:
All turnouts below 35% from 1918 onwards:
|Bethnal Green North East||1918||31.2|
|Aberdeenshire and East Kincardineshire||1918||34.2|
Until 2001, the lowest turnout after 1918 was 37.4% in Orkney and Shetland in 1922.
Any number of candidates can be nominated for election under current UK electoral law. The only restrictions are that a candidate must be a Commonwealth or Irish citizen, not legally disqualified, with the valid nomination of ten electors from the constituency. Candidates must pay a £500 deposit which is only refunded if the candidate wins 5% or more of the votes cast.
Fourteen constituencies have seen more than ten candidates stand in a general election:
|13||Uxbridge and South Ruislip||2015||None|
|12||Hackney South and Shoreditch||2010||Meg Hillier|
|11||Isle of Wight||2010||Andrew Turner|
|11||Bethnal Green and Bow||2010||None|
|11||Camberwell and Peckham||2010||Harriet Harman|
|11||Bethnal Green and Bow||2015||Rushanara Ali|
|11||Camberwell and Peckham||2015||Harriet Harman|
|11||Hackney South and Shoreditch||2015||Meg Hillier|
The two cases from before 2010 were both the constituency of the Prime Minister. Before 1983, the consecutive records were 6 candidates in Paddington North in 1918, 7 in Tottenham in February 1974 and 9 in Devon North in 1979.
The last four seats to be uncontested at a general election were Armagh, Londonderry, North Antrim and South Antrim, at the 1951 general election. The last mainland seats to be uncontested were Liverpool Scotland and Rhondda West, at the 1945 general election.
Buckingham was the only seat contested by only three candidates at the 2015 general election. Traditionally, the Speaker of the House of Commons is not opposed by major parties, so the only opposition to John Bercow was candidates from the Green Party and from UKIP. However, in the 2017 UK general election, there were 21 seats with only three candidates, all in England.

Possibly the oldest known first-time seat winner was Bernard Kelly (born 1808) who was aged 77 when he became the first MP for the then new seat of South Donegal in Ireland at the 1885 general election. He died aged reportedly 78 on 1 January 1887. Others:

- Mancherjee Bhownagree, Bethnal Green, 1895 and 1900

First general election victors from specific religions
When the UK Parliament was established in 1801, non-Anglicans were prevented from taking their seats as MPs under the Test Act 1672. However, Methodists took communion at Anglican churches until 1795, and some continued to do so, and many Presbyterians were prepared to accept Anglican communion, thus ensuring that members of these creeds were represented in the Parliament. Some Unitarians were also elected.
The first declared atheist to win a general election was Charles Bradlaugh at the 1880 general election. He was not permitted to take his seat in that parliament, but was elected again at the 1885 general election and allowed to take the oath.
General elections losers awarded seats on disqualification of winner
Two or more sitting MPs contest general election
It is of course common for former (defeated) MPs to seek re-election, often in their old constituencies, especially if they are marginal or bellwether seats. What is quite unusual is for two MPs both sitting in the same parliament to seek re-election in the same seat. This usually occurs by reason of boundary changes or party splits.

Notes: 1after announcing his retirement as member for Central Fife, long-serving Scottish Labour MP Willie Hamilton obtained his party's nomination in the hopeless prospect of South Hams in southern England. Hamilton insisted that he knew local parties often found themselves without candidates shortly before nominations closed, and was offering because it would help them out of difficulty; however by standing again and being "defeated" he qualified for an additional allowance.

Longest period without a change in government
The longest continuous Conservative government was in office for almost 18 years, between 4 May 1979 and 2 May 1997.
The longest continuous Labour government was in office for over 13 years, between 2 May 1997 and 11 May 2010.
The longest continuous Liberal government was in office for over 9 years, between 5 December 1905 and 25 May 1915.
The longest continuous coalition government was in office for almost 14 years, between 24 August 1931 and 26 July 1945, although its components changed significantly during that period.
Currently, all British Parliamentary elections are invariably held on a Thursday. The last general election not held on a Thursday was the 1931 election, which was held on Tuesday 27 October. Prior to this, it was common to hold general elections on any day of the week (other than Sunday), and until the 1918 general election, polling (and the declaration of results) was held over a period of several weeks.
On rare occasions, polling in an individual constituency may be suspended, usually as a result of the death of a candidate. The last occasion was at Thirsk and Malton in 2010, where polling was delayed for three weeks owing to the death of the UKIP candidate.

Outgoing Government gains seats
When there is a decisive change in electoral sentiment, a tiny number of seats will not only buck the trend by not moving as expected, but may actually move in the opposite direction. Only elections that saw a change of government are listed, since it is fairly common for a few seats to move in divergent directions when an incumbent government is re-elected; 2005 was an exception to this case, when the Labour party scored no gains.
