The Great British Vote

The Great British Vote is an independent, non-partisan online polling platform that tracks how UK residents would vote in the next general election. Our aim is to give every person in the country a voice — not just those selected for traditional polling samples — and to show, in real time, how voting intentions vary across every Westminster constituency. Our intention is to provide better information to UK citizens, journalists and politicians in the hope that this will improve the quality of future elections. We also hope that our poll encourages people who are politically disengaged or choose to abstain to get engaged and show up to future elections.

Anyone with a UK address can submit their voting intention by entering their postcode, selecting their preferred party, and creating a verified account. Results are displayed live on an interactive map of all 650 Westminster constituencies and updated in real time as new votes come in.

The Great British Vote is open to all UK residents, including those under the age of 18. We believe that young people should be allowed to share their opinions and hope that their participation will give valuable insights into the country's politics. By default, results shown on the map reflect voters aged 18 and above so as not to cause confusion, though users can filter results to show any and all demographics, including how a general election result would look if the voting age were lowered.

We take the integrity of our data seriously. To submit a vote, every user must:

• Enter a valid UK postcode, which identifies their Westminster constituency
• Create an account with a verified email address — one account per email address
• Pass a CAPTCHA verification to prevent automated submissions

We also use IP geolocation to limit submissions to users accessing the site from within the United Kingdom, and rate limiting to prevent abuse.

We do not claim that these measures are infallible. A determined bad actor could theoretically submit a fraudulent vote. In the future we intend to add mobile verification to the site to limit participation to UK-only mobile numbers, but at this early stage in the site's life it is not yet cost effective. We are optimistic that in its current state, most potential bad actors would be deterred by the multiple layers of verification already in place. Any mass submissions that appear to be part of a coordinated campaign will be swiftly removed from the database.

No — and we want to be completely transparent about that. The Great British Vote is a self-selecting poll, meaning participants choose to take part rather than being selected at random. This is different from traditional polling, which uses carefully weighted samples designed to reflect the broader population.

Self-selecting polls tend to over-represent people who feel strongly about politics, have access to the internet, and are motivated to participate. They may under-represent older voters and politically disengaged groups. We hope that by giving people a free and accessible way to have their say, and by encouraging users to share the poll with others, we can close this gap over time.

You should not treat our results as a precise prediction of how an election would turn out. What our data does show is a broad picture of sentiment — particularly useful at constituency level, where traditional polls rarely venture.

Each registered user has one active vote at any time. If a user changes their vote, only their most recent selection is counted in the live results.

Constituency results are only displayed once a minimum of 50 votes have been submitted for that constituency. Below this threshold, constituencies are shown in grey on the map. This is to prevent misleading results from very small samples.

Results show the percentage of votes received by each party within a constituency, based on verified accounts only. Unverified accounts — where the user has not clicked the confirmation link in their email — are not counted.

When submitting a vote, users are optionally asked to select a second and third choice party — the parties they would be willing to vote for if their first choice were not available. This data gives a picture of tactical voting sentiment across the country and helps identify where voters feel their politics is underrepresented by the current party system.

Second and third choice data is displayed separately from first choice results and does not affect constituency colours on the map, which are determined by first choice votes only. This data is particularly valuable in marginal constituencies, where understanding the preferences of voters whose first choice has little chance of winning can reveal significant shifts in potential voting behaviour.

When submitting a vote, users are asked to optionally provide their age range, gender, and ethnicity. This data is used solely to allow filtering of results by demographic group — for example, to see how voting intentions differ between age groups or across different communities.

Demographic data is anonymised and aggregated. It cannot be linked back to individual votes and is never shared with third parties.

The poll runs in cycles of approximately three months. At the end of each cycle, registered users who have opted in will receive an email reminder inviting them to resubmit or update their vote. Historical data from previous cycles is retained and will be made available for research purposes in future.

The Great British Vote is an independent project. We have no affiliation with any political party, campaign group, or media organisation. We do not accept advertising. The site is funded entirely through voluntary donations from users who want to support independent civic technology.
