Are you registered to vote?
In order to be added to the Register of Electors, you must make an application to the Elections Office. You are not automatically registered to vote, even if you pay council tax, or have registered to use other council services.
The registration process can be performed online through the Register to Vote page of the government gateway website (National Insurance number may be required).
It is not possible to check online whether you are registered on the Electoral Register, but if you contact the Elections Office, they will be able to confirm whether you are registered.
