Street naming and numbering

Naming of new streets and registering of properties

The naming and number of new streets and properties is a statutory requirement completed by the Council under Sections 64 and 65 of ‘The Town Improvements Clauses Act 1847’.

This includes:

  • new streets
  • new properties
  • renaming existing streets (subject to public consultation)
  • renumbering buildings

When and how to apply for street naming and numbering

If you’re undertaking a development or converting a property we advise you contact us as soon as planning permission and building regulations have been granted so that we can provide you with advice on completing the application process.

Please note: streets involving royal connotations must be approved by both the council and Cabinet Office, if you intend on naming a street with the use of the word ‘royal’ or any royal connotations it is advised to submit your application as early as possible to avoid any potential delays.

Use of the number 13

When submitting an application for street naming the number 13 will be used in all numbering sequences without exception.

How to apply

Your application must have a description of the works and the following information:

  • planning application reference number*
  • building regulations application number
  • three alternative suggestions for street names, in order of preference (if creating a new street)
  • 1:1250 ordnance survey location plan
  • site layout plan (for larger developments)
  • applicants current postal address

Please note: A street naming and numbering application can only be made valid if planning permission has been granted. Applications where planning permission has not been granted will be placed on hold until permission is granted.


When building or converting a property into flats the addressing for ‘flat numbers’ will be used (notletters) for example:

  • Flat 1, 15 Victoria Street
  • Flat 2, Smith House, John Street

Change of name or adding an alternative property name

Royal mail and the emergency services must agree to this change providing there is no duplication in the immediate area. If a property has a number this number will still be the principal address of the property.

Postal delivery problems

If you have an address query or wish to register your property as an active address with both the council and royal mail please send an email to [email protected].
