Below are the results of our latest opinion poll, with data collected between 7th and 16th September 2026.

All data was collected online through Potentia Insight, a panel provider. The sample is nationally representative and has been collected to strict age, gender and region quotas. These data have been weighted to be representative of the 2024 General Election official turnout and voting figures. Trajectory are members of the British Polling Council and all polls are conducted in accordance with their rules. Full details of our methodology can be found here.

There has been one change to our standard voting intention question this month. We have stopped prompting for UKIP and have started prompting for Restore Britain.

Headline voting intention (all adults) is:

  • Reform: 22% (+1)
  • Labour: 29% (+1)
  • Conservatives: 21% (+1)
  • Green: 10% (-)
  • Liberal Democrat: 10% (-1)

Among those likely to vote:

  • Reform: 22% (-)
  • Labour: 30% (+2)
  • Conservatives: 21% (+1)
  • Green: 9% (-)
  • Liberal Democrat: 10% (-1)

The tables are available to download here. All changes are against our August 2026 polls.
