House Effects How pollsters lean relative to average
What this shows: How each pollster's results systematically differ from the cross-pollster average at the time each poll was conducted. A positive value means the pollster tends to report that party higher than peers; negative means lower.
What this does not show: These are not measures of polling accuracy or quality. Differences often reflect legitimate methodological choices: sampling frames, weighting strategies, question wording, and mode effects all produce systematic variation. A pollster with large house effects may ultimately prove closest to the election result.
Only the five main GB-wide parties are shown. Effects may not sum to zero per pollster because smaller parties (SNP, Plaid Cymru, Other) absorb the remainder.
About Poll Aggregation
Our poll average uses exponential decay weighting with a 14-day half-life, giving more weight to recent polls. Sample size is also factored in using sqrt scaling. House effects are adjusted based on historical pollster bias. The aggregation also incorporates signals from foreign elections and UK local elections.
