The next general election in the United Kingdom is scheduled to be held on 5 May 2022 under the Fixed-term Parliaments Act 2011. The election may be held at an earlier date in the event of an early election motion being passed by a super-majority of two-thirds in the House of Commons, or a vote of no confidence in the government which is not followed by a vote of confidence within 14 days.
Each parliamentary constituency of the United Kingdom elects one MP to the House of Commons using the first-past-the-post voting system.
- on the Electoral Register;
- aged 18 or over on polling day;
- a British, Irish or Commonwealth citizen;
- a resident at an address in the United Kingdom (or a British citizen living abroad who has been registered to vote in the UK in the last 15 years);[n 10] and
- not legally excluded from voting (for example a convicted person detained in prison or a mental hospital, or unlawfully at large if he/she would otherwise have been detained, or a person found guilty of certain corrupt or illegal practices) or disqualified from voting (peers sitting in the House of Lords).
Individuals must be registered to vote by midnight twelve working days before polling day. Anyone who qualifies as an anonymous elector has until midnight six working days before polling day to register.[n 11] A person who has two homes (such as a university student who has a term-time address and lives at home during holidays) may be able to register to vote at both addresses as long as they are not in the same electoral area, but can only vote in one constituency at the general election.
It is current UK government policy to pass a law removing the 15-year limit on expatriate Britons voting before the next general election takes place, as mentioned in the 2017 Conservative Party manifesto, which stated (page 42) "We will legislate for votes for life for British overseas electors".
The postponed Sixth Periodic Review of Westminster constituencies proposed reducing the number of constituencies from 650 to 600. In April 2016, each of the four parliamentary Boundary Commissions of the United Kingdom recommenced their review process.
After each Commission published their Final Recommendation reports on 10 September 2018, psephologists Rallings and Thrasher of Plymouth University projected the result of the 2017 election as if the new boundaries had been in place.
|Party||Projected seats||Net loss||Seat %|
|Scottish National Party||33||2||5.5|
|Democratic Unionist Party||10||1.7|
|Green Party (England & Wales)||1||0.2|
Date of the election
The Fixed-term Parliaments Act 2011 introduced fixed-term parliaments to the United Kingdom, with elections scheduled on the first Thursday in May of the fifth year after the previous general election.
Removing the power of the monarch, on advice of the prime minister, to dissolve parliament before its five-year maximum length, the act permits early dissolution if the House of Commons votes by a two-thirds supermajority, as occurred in the 2017 general election. Parliament is also dissolved if a government loses a vote of no confidence by a simple majority and a new government is not formed within 14 days. The Conservative Party manifesto at the 2017 general election proposed repealing the Fixed-term Parliaments Act 2011, although this has yet to occur.
Thus, the next general election is due to take place on 5 May 2022, unless it is triggered earlier. Under the Electoral Registration and Administration Act 2013 parliament would be dissolved 25 working days before this date on 28 March 2022. Under the Fixed-term Parliaments Act the prime minister may schedule polling day up to two months after 5 May 2022, subject to approval by both Houses.
Following arguments about Brexit and the failure of Parliament to support May's Brexit deal at the meaningful vote in January 2019, the Labour Party called a vote of no confidence, although this failed. However, the New Statesman reported that Conservative ministers were preparing local parties for a possible general election on 28 February 2019. Over the first weekend of February, there was speculation that Theresa May was planning to call a snap election for Thursday 6th June.
Contesting political parties and candidates
Most candidates are representatives of a political party, which must be registered with the Electoral Commission's Register of Political Parties. Candidates who do not belong to a registered party can use an "independent" label, or no label at all. At the 2017 general election, representatives of 71 parties stood for election, and 462 people stood as independents. 
|Party||Party leader(s)||Leader since||Leader's seat||Last election|
|Conservative Party||Theresa May[n 5]||July 2016||Maidenhead||42.4%||317|
|Labour Party||Jeremy Corbyn||September 2015||Islington North||40.0%||262|
|Scottish National Party||Nicola Sturgeon||November 2014||None[n 3]||3.0%||35|
|Liberal Democrats||Vince Cable||July 2017||Twickenham||7.4%||12|
|Plaid Cymru||Adam Price||September 2018||None[n 12]||0.5%||4|
|Green Party (England & Wales)||Jonathan Bartley||September 2016||None[n 13]||1.6%||1|
|Siân Berry||September 2018|
In February 2019, eleven MPs from both the Labour and Conservative parties resigned from their parties to sit together as The Independent Group, but they have not registered to form a new political party so far.
Tim Farron announced his departure as Liberal Democrat leader shortly after the June 2017 election. He was replaced by Vince Cable. In September 2018, Cable stated his intention to resign as Leader of the Liberal Democrats 'once Brexit is resolved or stopped'. The United Kingdom is scheduled to exit the European Union in March 2019, before the planned date of the next election. Facing a no confidence vote within her party in December 2018, Theresa May told MPs she would not contest the next scheduled general election (i.e. in 2022) as leader.
While a number of UK parties organise in Northern Ireland (including the Labour Party, which does not field candidates) and others field candidates for election (e.g., Conservative), the main Northern Ireland parties are different from those in the rest of the UK.
|Party||Leader(s)||Leader since||Leader's seat||Last election|
|Democratic Unionist Party||Arlene Foster||December 2015||None[n 9]||36.0%||10|
|Sinn Féin||Mary Lou McDonald||10 February 2018||None[n 7]||29.4%||7|
|Social Democratic & Labour Party||Colum Eastwood||November 2015||None[n 14]||11.7%||0|
|Ulster Unionist Party||Robin Swann||April 2017||None[n 15]||10.3%||0|
|Alliance Party||Naomi Long||October 2016||None[n 16]||7.9%||0|
