Street name and numbering

We assign street names and house numbers and provide the emergency services, Land Registry, and relevant council services with a copy of the naming/numbering schedule. Royal Mail is notified of all addresses. They allocate and administer postcodes. You can check to see if you address is registered with Royal Mail.

We name streets on new developments and assign numbers to individual properties.

If the owner of an existing property has a house name, rather than a house number, and wants to make a change, we also administer that process.
