Opinion polling for the next United Kingdom general election

Various organisations continually conduct opinion polls to gauge voter intention in anticipation of the next United Kingdom general election. The next general election must be held no later than 15 August 2029 under the Dissolution and Calling of Parliament Act 2022, which mandates that any Parliament automatically dissolves five years after it first met – unless it is dissolved earlier at the request of the prime minister – and polling day occurs no more than 25 working days later.

Most of the polling companies listed are members of the British Polling Council (BPC) and abide by its disclosure rules. The dates of the polls range from the 2024 United Kingdom general election, held on 4 July, to the present.

The chart below shows opinion polls conducted since the 2024 general election. The trend lines are local regressions (LOESS). The bar on the left represents the previous election, and the bar on the right represents the latest possible date of the next election.

Most opinion polls do not cover Northern Ireland, which has different major political parties from the rest of the United Kingdom. This distinction is made in the tables below in the area column, where "GB" means Great Britain (England, Scotland and Wales), and "UK" means the entire United Kingdom. Plaid Cymru stands candidates only in Wales and the Scottish National Party stands candidates only in Scotland. Due to rounding, total figures may not add up to 100%. The lead is calculated by subtracting the polling percentage of the first party (shaded in the party's colour, and in bold) by that of the second party (shaded in grey).

326 seats are needed for a majority.

All multilevel regression with poststratification polls have been conducted excluding the 18 seats in Northern Ireland.

Political Analysis through Regional and Local Insights System (POLARIS) is a novel model created by JL Partners, using council by-elections to predict election outcomes. All models from January onwards are combined with a representative survey data, with the data used shifted to reflect the pollster's most recent national polling.

In the run-up to the 2026 Gorton and Denton by-election, Mayor of Manchester Andy Burnham launched a bid to become the Labour candidate, leading to speculation that he could mount a leadership challenge against Prime Minister Keir Starmer. However, on 25 January 2026, Labour's National Executive Committee (NEC) blocked Burnham from standing for the party.

For the 2024 Conservative Party leadership election, Electoral Calculus conducted a multilevel regression with poststratification (MRP) opinion poll on behalf of Jack Lewy of the Robert Jenrick campaign, asking the general public how they would vote if respectively Kemi Badenoch or Robert Jenrick were elected leader of the Conservatives.

YouGov has conducted polling on scenarios wherein only two parties appear to have a chance of winning a constituency.

In July 2025, the Government announced their intention to reduce the voting age to 16 before the next general election. Following this, some pollsters conducted polling including 16–17-year-olds, although the voting age has not yet been reduced by law.

Some pollsters also conducted polling solely among 16–17-year-olds, or broke out an oversample of this group.

Merlin Strategy conducted polling solely among those who would be eligible to vote in 2029, the latest possible date for the election.

In 2025, Jeremy Corbyn and Zarah Sultana founded a new political party, called Your Party. Prior to the announcement of these plans, polling was carried out about the idea for a hypothetical new party. After the announcement of the plan for a new party, more polling was carried out.

326 seats needed for a majority.

In June 2025, former Reform MP Rupert Lowe launched a political organisation called "Restore Britain", advocating a harder line on immigration than Reform UK. Find Out Now were asked by the organisation to poll on a hypothetical new party led by Lowe. In February 2026, Lowe announced that Restore Britain would become a political party.

Additionally, a poll was commissioned for the constituency of Great Yarmouth for a new (although unregistered at the time) party "Great Yarmouth First" led by Lowe. The sample size of this poll was significantly smaller than standard polling leading to a wider margin of error.

Great Yarmouth First was registered with the Electoral Commission as a political party on 4 March 2026.
