The short answer
A UK passport does not show your address, so a house move does not require a new one.
What you actually need to change
- Driving licence (our guide). Free and done online in a few minutes at gov.uk/change-address-driving-licence.
- Electoral roll (our guide). Register at your new address with your local council, or via gov.uk/register-to-vote.
- Royal Mail redirection (our guide). Set one up before moving day so post keeps reaching you: royalmail.com/personal/receiving-mail/redirection.
Council tax, your GP, the TV licence, banks and utilities also need your new address. The moving house checklist lists each one with the official link and when to do it.
