Street naming, numbering and addresses

When to use this addressing service

If you need a:

  • new street named
  • building named and/or numbered
  • building re-named and/or re-numbered
  • existing street named and/or re-named

For new streets and buildings you should make an application well before they become occupied, as utility companies are reluctant to install services without an official postal address and postcode and will take approximately a month to complete.

Who should apply?

If you are:

  • building new houses, commercial or industrial premises
  • converting residential, commercial or industrial premises that will result in a creation of new properties or premises
  • wishing to change the registered name of a property
  • wish to add or change an alias name to a registered numbered premises

Please note, if you are not the freehold owner of the property concerned, you must seek the owner's written permission and submit this with the application.

How do I apply?

You will need to download and return an application form:

Alias names

If the property already has a house number it cannot be replaced with a name. However, we will allow the addition of an alias name to the address. The name will be held by Royal Mail on their 'alias file' and will not form part of the official address.

The alias name can only be used in conjunction with the property number, not as a replacement.

Further information

How long will it take?

If your application relates to a new address on an existing street, or a change of name to a property, we will aim to allocate or confirm the change within five working days from receipt of a valid application.

If your application involves the naming of new streets, due to the consultation process involved we will aim to allocate a postal address within one month from receipt of a valid application.

If your application requires a new postcode, this is allocated by Royal Mail and will normally take up to an extra 10 working days for your application to be completed.

Our certificate to you confirming the result of your application is your official street naming and numbering certificate. A copy of this will be forwarded to other official organisations including:

  • The Royal Mail
  • Emergency Services
  • Land Registry
  • Ordnance Survey and some main utilities as well as certain Council offices including Council Tax.

Please note that personal details given on the application form will be forwarded to internal departments only for use in connection with the site of the application.

Any new addresses will be held on "Not yet built files" until they are complete and may not be visible on address databases, i.e. Royal Mail. Once complete they will then be transferred to "live" systems. This will then filter down to third parties address databases, i.e. internet, sat navs. When updates have been received by them. The update of third party databases can take up to a year.
