  • changes to and allocation of property names
  • renaming of streets and renumbering of properties

New addresses for developments

If you are building a new property or properties, or replacing or redeveloping an existing property into multiple dwellings, you should contact us as soon as possible to arrange for the allocation of addresses.

If you are developing a new street or estate, you should contact us to arrange the numbering of properties and naming of streets as soon as you are ready to begin working on the site as the naming of streets can be a lengthy process.

For a new property we will assign a new number. However, where this is not possible, for example on a road where all the properties already have names and not numbers, we will issue a new property with a name.

Adding a name to your numbered property

If you have a numbered property, you may add a property name to the dwelling. However, the house name can only be used in conjunction with the number and not replace it. When choosing a property name, the name should not be the same as, or similar to, another house name in the area. Property owners wishing to add a property name to an existing numbered address will need to complete an application and pay a set fee.

Changing your property name

We also authorise property name changes. If your property has a name and not a house number and you wish to change the name, you have to obtain approval from us. This is to ensure there is no duplication of house names in the same settlement or locality, which could lead to problems for the emergency services and Royal Mail when locating the property.
