National polling and vote-share tracker
GB-wide polling averages for the major parties, with change from the previous averaging period and difference from the 2024 general election result.
Data status
No polling averages are populated on this page yet. We do not publish a polling average yet. Poll aggregation needs a source we have checked and approved, and none of the aggregators has been through that check — so rather than pick one and present its numbers as ours, the tracker stays empty until it has.
No averaging method is published yet either. How polls are combined — which ones, over what window, weighted how — changes the answer, so we will set out the method here alongside the first average rather than after it.
Once populated, this tracker will never describe ordinary polling noise (movement within a normal margin of error between averaging periods) as a definite change — only a movement large enough to be distinguished from noise will be described as a change.
