The location of your polling station is always printed on your poll card.
If you go to another station you will not be able to vote there, so please make sure you check.
You can enter your postcode in the polling station finder on the Democracy Club website to find an address and a map for your polling station.
Please note that their polling station finder is updated only shortly before elections.
This means the search might not return any results for you until a few days before the election is due to take place and will just display a message about there not being any elections in that area.
