Street naming and numbering

The London Borough of Barnet is the Street Naming and Numbering Authority responsible for the naming and numbering of new and existing streets and buildings and is the only organisation that can create or change addresses within its boundaries.  Under the London Building Acts (Amendment) Act, 1939, the Local Authority has the legal responsibility to ensure that streets are named and buildings are numbered and has the powers to approve or reject building and street address suggestions submitted by developers.

Our Street Naming and Numbering service will:

  • assign street names and street numbers to new and existing streets, houses and buildings
  • carry out renaming and renumbering of streets, houses and buildings
  • liaise with the London Emergency Services and Royal Mail to ensure that any proposed names or street numbers do not cause confusion to these services in carrying out their duties.

Street Naming and Numbering is an important function that allows the Local Authority to maintain a comprehensive and accurate address database covering all properties within the borough.  In turn this enables:

  • emergency Services to find a property quickly and efficiently
  • post to be delivered efficiently
  • visitors to locate their destination
  • records of service providers to be kept in an efficient manner
  • all of the Local Authority’s departments to work from one official address base
  • reliable delivery of services and goods by courier companies
  • companies to accept an address for official purposes.  For example, insurance, credit rating, contract acceptance.

Please note: Street naming applications within built-up areas may be subject to full public consultation. Where a new road name is being sought, we will issue a full public consultation, which will allow for a period of 28 days for local residents to voice opinions or raise objections about the proposed name(s).

Retrospective numbering undertaken when a developer has failed to apply for Street Naming and Numbering but requires addresses for an existing building will be subject to charge.

The Local Authority defines all elements of an address, with the exception of the postcode and post town.  The numbers and names assigned to buildings and the official names assigned to streets are the Intellectual Property of the authority.

It should be noted that the Street Naming and Numbering process can be a lengthy one.  Therefore, it is advisable to submit an application as early as possible in the proposal stage, preferably before works commence and ideally before an unofficial name has been marketed or legal documents drafted.
