How to check your nearest polling station
You can find your assigned polling station by entering your postcode into one of these official tools:
• Where Do I Vote? A dedicated tool that allows you to find your polling station by postcode.
Most local councils also provide their own maps and polling station finders, such as those for Newham, Redbridge and Camden.
You should also have received a polling card a few weeks before the election detailing your nearest station.
It is important to note you must vote at your assigned polling station; you cannot use a different one, such as near your workplace or college.
Do you need your polling card to vote?
You do not need to bring this card with you to vote, but it remains the most reliable record of where you are registered to cast your ballot.
You will need to bring photo ID to vote in person at a polling station. This can be out of date, as long as the photo still resembles you.
What time do polling stations close?
Polling stations are open from 7am until 10pm. As long as you are in the queue by 10pm, you will still be allowed to vote.
