Street naming and numbering

Our services

The street naming and numbering service:

  • assigns names and postal addresses to new and existing streets, houses and buildings
  • carries out renaming and renumbering of streets, houses and buildings
  • liaises with the London Fire Brigade, London Ambulance Service and Post Office to ensure that any proposed name or postal number does not cause confusion to these services in carrying out their duties
  • holds a list of approved names for your use

How we can help you

You will need to apply to the street naming and numbering service if you require:

  • a building to be named and / or numbered
  • a building to be renamed and / or renumbered
  • a new street to be named

When your application has been processed, we will issue a statutory order which gives the new naming or numbering official status. Royal Mail will not assign a postcode to a new building without a statutory order.

For new streets and buildings you should make an application well before they become occupied. This is a requirement under Part II of the London Building Acts (Amendment Act) 1939.

How to make an application

Download a street naming and numbering application form (pdf, 94kb) or contact the street naming and numbering service. Please ensure that you read the guidelines on making the application (pdf, 159kb).

Send us your completed application form and fee and include a 1:1250 plan with your application. Each entrance to be numbered should be indicated on the plan with a red arrow. You will need the freeholder's permission before any change to the name or number of a building.

How long it will take

We aim to process all applications for naming and numbering or renaming and renumbering of buildings in existing streets within one month of receipt. We aim to process applications for naming or numbering of new streets, both private and public, within three to six months of receipt.

If a name is chosen from our list of approved names this will speed up the process. The list of names will be sent to you with your application form.
