If you want your voice to be heard in a general or local election, you must be registered to vote. The University and the town of Hatfield are in the Welwyn Hatfield local authority.
If your home and University addresses are in two different local authority areas, you can vote in local elections in both. However, even if you are registered in two areas you can only vote once in a general election, it is a criminal offence to vote twice in a UK general election.
You can register to vote online.
