Welsh Westminster Polls

On this page are the latest Welsh Westminster polls for the 2024 general election together with a uniform swing calculation of the polling average. The seat and majority calculations are lifted directly from the 2024 General Election Swingometer for Wales.

Note: General Elections are scheduled to be held a maximum of 5 years from the first meeting of parliament plus 25 working days in accordance with the Dissolution and Calling of Parliament Act 2022. We will refer to the election as if it were to be held in 2024 unless it becomes clear that an early general election will happen.

Here is the polling average of the polls below together with the seat changes on a uniform swing. Information on how the polling average is calculated is available here.
