Next United Kingdom general election

The next United Kingdom general election is scheduled to be held no later than 15 August 2029. It will determine the composition of the House of Commons, which determines the government of the United Kingdom.

Background

2024 election

The 2024 general election resulted in a landslide victory for the Labour Party led by Keir Starmer, but with the smallest share of the electoral vote of any majority government since record-keeping of the popular vote began in 1830. The combined vote share for Labour and the Conservatives reached a record low, with smaller parties doing well. Labour returned to being the largest party in Scotland and remained so in Wales. The election was noted as the most disproportionate in modern British history, mainly as a result of the first-past-the-post voting system.
The Conservative Party under Rishi Sunak lost 251 seats and suffered their worst ever defeat, ending their 14-year tenure as the primary governing party. The Conservatives won no seats in Wales and only one seat in North East England. On 2 November 2024, Kemi Badenoch won the 2024 Conservative leadership election to succeed Sunak becoming the first Black British person to become the Conservative leader.
Reform UK, led by Nigel Farage, placed third in the share of the vote in the 2024 election and had MPs elected to the Commons for the first time. Meanwhile, the Liberal Democrats, led by Ed Davey, made significant gains especially in seat terms to reach their highest number of seats since the 1920s. The Green Party of England and Wales also won a record number of votes and seats alongside a number of independent MPs. The Scottish National Party lost around three-quarters of its seats.

Current composition of the House of Commons

Events since 2024

The 2025 United Kingdom local elections led to a rise in the number of seats held by smaller parties at the expense of the Conservatives and Labour. On 2 September 2025, Zack Polanski was elected as leader of the Green Party of England and Wales in a landslide, with 85% of the vote share, succeeding Carla Denyer and Adrian Ramsay in that position. The party's membership figures doubled, from around 70,000 to over 140,000, overtaking the Liberal Democrats and Conservatives.

By-elections

Runcorn and Helsby

On 24 February 2025, incumbent Labour MP for Runcorn and Helsby, Mike Amesbury, was sentenced to 10 weeks in prison for assault which was reduced to a suspended sentence, however, a recall petition was held with Amesbury resigning on 17 March 2025. The by-election was characterised in the media as a fight between Labour and Reform UK. Labour would select Karen Shore, a former teacher and deputy leader of Cheshire West and Chester Council, as their candidate, as Reform UK picked Sarah Pochin, a former Cheshire East Conservative Party councillor before being expelled from the party in 2020. Meanwhile minor candidates included the Conservatives standing Sean Houlston, a National Federation of Builders executive and former candidate for the neighbouring seat of Widnes and Halewood, and the Greens picked Chris Copeman, a local councillor in Helsby as their candidate. Other candidates included Michael Williams as an independent, Danny Clarke for the Liberal Party, and Jason Hughes for Volt UK.
Pochin and Reform UK won the by-election, overturning Labour's 14,696-vote majority from the last general election with Pochin being the first non-Labour MP to hold the seat in 50 years. The initial vote count saw Pochin win with just 4 votes, which was extended to 6 votes following a Labour requested recount. It was the closest by-election result since at least the Second World War, the previous narrowest being a majority of 57. The results were seen as a major upset for Reform UK as Labour pinning their defeat on cuts to the winter fuel payment.

Electoral system

Voting eligibility

Presently, in order to vote in general elections, one must be:

on the Electoral Register,
aged 18 or over on polling day,
a British citizen, a Commonwealth citizen or a citizen of the Republic of Ireland,
a resident at an address in the United Kingdom, and
not legally excluded from voting

Individuals must be registered to vote by midnight twelve working days before polling day. Anyone who qualifies as an anonymous elector has approximately five working days before polling day to register. A person who has two homes 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. In July 2025, the government announced plans to reduce the voting age to 16 before the next general election. Extending the vote to 16- and 17-year-olds would add well over a million potential voters across England and Northern Ireland. Analysts found that this would expand voter participation, but the additional votes would represent only a small share of the national electorate.

Date of the election

Under the Dissolution and Calling of Parliament Act 2022, the prime minister has the power to request the monarch call an election at any time during the five-year length of a parliamentary session. If the prime minister chooses not to do this, then parliament is automatically dissolved five years after the day it first met, and a general election is held 25 working days after dissolution. Parliament first met on 9 July 2024, meaning that unless Parliament is dissolved earlier it will be automatically dissolved on 9 July 2029, and the latest an election could be held is 15 August 2029.

Opinion polling

Opinion polling for the next United Kingdom general election is being carried out continually by various organisations to gauge voting intention. Most of the polling companies listed are members of the British Polling Council and abide by its disclosure rules. The dates for these opinion polls range from the 2024 general election on 4 July to the present day.
