About This Site

About UKPollingData.com

UKPollingData.com is an independent tracker of British public opinion polling. We aggregate voting intention data from all major British Polling Council-registered firms, build a rolling cross-firm average, and publish analysis to help readers understand what the polls are showing and why.

We have no political affiliation. We do not receive funding from any political party, campaign, or advocacy organisation. Our only interest is in presenting polling data accurately and explaining it clearly.

What we do

At the most basic level, UKPollingData.com does three things:

1. Aggregate: We collect every published UK voting intention poll from BPC-registered firms and enter it into our database. Each poll is recorded with the firm name, fieldwork dates, sample size, methodology, and topline figures.
2. Average: We compute a rolling poll-of-polls average using a weighting system that accounts for recency, sample size, and documented house effects. The full methodology is explained on our methodology page.
3. Explain: We publish analysis articles, explainers, and issue trackers that put the numbers in context. Raw percentages tell you what the polls show; our editorial content helps explain what they mean.

Data sources

All voting intention data on this site comes from polls published by members of the British Polling Council. These include:

• YouGov — weekly, sometimes more frequent
• Ipsos UK — monthly Political Monitor
• Redfield & Wilton Strategies — near-daily tracker
• Techne UK — weekly
• Deltapoll — periodic, typically monthly or on-event
• Survation — periodic
• More in Common — large-scale research surveys

We do not publish data from firms that are not BPC members. We do not use internal party polling or data from non-disclosed private surveys. Every number on this site can be traced back to a publicly available, disclosed poll.

Our editorial approach

Polling data is often misread — by politicians, by journalists, and by members of the public. The most common errors include treating a single poll as definitive rather than one data point in a range, ignoring house effects, misunderstanding margins of error, and failing to distinguish between voting intention and actual vote share at an election.

Our editorial approach is designed to guard against these errors:

• We always show the cross-firm average, not just the latest individual poll. A single poll that shows an unusual result is not evidence of a trend; a consistent movement across multiple firms over several weeks is.
• We explain house effects. Each pollster page on this site includes a section on how that firm’s figures typically compare to the cross-firm average, and why.
• We contextualise with history. Where relevant, we compare current figures to equivalent points in previous electoral cycles. Current polling does not occur in a vacuum.
• We distinguish between polling and elections. Voting intention polls measure current stated preferences, not how people will vote at an election that may be years away. We are clear about this distinction throughout the site.

No political affiliation

UKPollingData.com is strictly non-partisan. We report the numbers as they are, not as any particular party or movement would like them to be. When a poll shows a party doing well or badly, we report that straightforwardly without editorialising in favour of or against any political position.

We apply the same methodological scrutiny to all parties equally. If a high Reform UK figure from Techne or Redfield & Wilton reflects a known house effect, we say so — just as we would note if a firm systematically under-recorded any other party.

We do not publish opinion columns, endorsements, or advocacy content. Our analysis pieces are descriptive and explanatory, not normative.

How to use this site

If you want to understand what the polls are currently showing, start with the voting intention tracker. It shows the cross-firm average for all major parties and the individual firm figures side by side.

If you want to understand how different pollsters compare, visit the pollsters section. Each firm has a profile page explaining their methodology, recent figures, and track record.

If you want to understand how polling works — what voting intention means, what MRP polls are, how margins of error work — visit our explainers section.

If you want to follow specific issues or topics, the issues tracker covers NHS satisfaction, immigration attitudes, cost of living, and other key policy areas.

Accuracy and corrections

We make every effort to enter polling data accurately. If you believe we have made an error in a figure, a date, or a methodological description, please contact us via the contact page. We take corrections seriously and will update any verified errors promptly, noting the correction in the relevant page.

Privacy and advertising

UKPollingData.com does not use invasive tracking or behavioural advertising. Our privacy policy explains exactly what data we collect and how we use it. We do not sell data to third parties.

About the poll-of-polls methodology

Our cross-firm polling average is not a simple mean of the most recent polls. We apply weighting based on recency (more recent polls count for more), sample size (larger samples count for slightly more), and a house-effect correction for firms with documented systematic biases. The full methodology is documented on the methodology page, which also includes a FAQ on common polling concepts.

Who we cover

We track all British Polling Council member firms that regularly publish UK voting intention data. Currently this includes YouGov, Ipsos, Redfield & Wilton Strategies, Techne UK, Deltapoll, Survation, and More in Common. Each firm has a profile page explaining their methodology, recent figures, and historical accuracy record.

We also track MRP polls when they are published by major firms. MRP models produce constituency-level seat projections rather than national vote share estimates, and require separate presentation. All published UK MRP figures are on our MRP seat projections page.

Issues and sub-national polling

Beyond national voting intention, UKPollingData.com tracks polling on key policy issues including NHS satisfaction, immigration, cost of living, and housing. Sub-national polling for Scotland is tracked separately on the Scotland page, which covers both Scottish Parliament voting intention and Scottish independence polling.

By-election polling and local election polls are tracked in the by-elections section. These local contests are important as early indicators of national sentiment — but must be interpreted carefully given local factors that can distort comparisons with national VI polling.

Party profiles

In addition to pollster profiles, we maintain party pages covering the current polling position of Reform UK, the Conservatives, the Lib Dems, the Greens, and the SNP. Each party page summarises their current polling position, trend, and key demographic strengths and weaknesses according to the available cross-tab data.

What UKPollingData is not

It is worth being explicit about what this site does not do. We are not a forecasting service: we do not publish seat projections based on a proprietary model, and we do not claim to predict electoral outcomes. We aggregate and explain what the polls say; we do not speculate beyond the data.

We are not a news service. We do not publish breaking political news, leadership speculation, or commentary on government policy except insofar as it helps contextualise polling movements. Our focus is the data, not the narrative.

We are not affiliated with any university, think tank, or research institution. We are an independent digital publication with a sole focus on UK polling data and methodology.

Standards we hold ourselves to

We apply a consistent set of standards to everything we publish on this site:

• Source transparency: Every voting intention figure we publish is attributed to the polling firm, the fieldwork dates, and the sample size. We do not publish unattributed data.
• Methodological honesty: Where a firm has a documented house effect, we say so openly — even when that means acknowledging uncertainty about whether our own polling average is precisely calibrated.
• Historical accuracy: We do not revise historical figures retroactively to make our past analysis look better than it was. If a poll was published with certain figures, those are the figures in our database.
• Political neutrality: We apply the same critical lens to polling that shows any party doing unusually well or unusually badly. Outlier polls are examined for methodological explanation regardless of which party benefits.

The current state of UK polling

In May 2026, the UK polling landscape is unusually complex. For the first time in the modern polling era, the cross-firm average shows three parties — Labour, Reform UK, and the Conservatives — within approximately 5–7 percentage points of each other, with no party commanding a clear lead. The Lib Dems are a significant fourth force in certain geographic areas. Under first-past-the-post, this fragmented national picture translates into highly uncertain seat projections, where small changes in vote share can produce very large swings in seat counts.

This makes high-quality, transparent polling analysis more important than ever. Understanding the difference between a firm with a known house effect and a genuine national shift, and understanding why current VI figures do not straightforwardly translate into seat outcomes, is essential for anyone trying to make sense of British politics in this period. That is what UKPollingData.com is here to provide.
