If you do not want to go to the polling station to vote in person, you can ask to make a postal vote.
A postal vote means that you are sent a ballot paper to fill in at home.
You choose what you want to vote for, put a cross next to it on the ballot paper and then send the ballot paper back to the council by post.
You have to ask for a postal vote before an election takes place. You can ask for a postal vote here: www.yourvotematters.co.uk/how-do-i-vote/voting-by-post
