If you have moved house since you last voted you must register at your new address - paying council tax does not mean you are registered to vote.
Everyone in your home must register individually. You can do this on the government website gov.uk.
You’ll need your National Insurance Number. If you can't find it you can find a lost national insurance number on gov.uk or call the National Insurance Numbers helpline on 0300 200 3502.
If you still can't give your National Insurance number you'll be asked to say why. We may contact you for more information so we can check your identity.
Applying to vote, doesn't automatically add you to the electoral register. We have to check your details first, then you'll get a letter either confirming that you're registered, or asking you for more information.
Check if you are registered if you aren’t sure.
