Street naming and numbering


We have a statutory duty to name streets and number properties in those streets including:

  • new developments (residential and commercial)
  • conversions of existing buildings
  • alteration to street and building names and numbers

No other organisations have this responsibility and as an individual or business, you can't choose your own property numbers, building names, or street names. Instead, you will need to apply for a formally registered address. The application allows you to propose suggestions for the street names which are reviewed as part of the formal consultation process.


Before applying, you must have relevant planning permission in place and be able to provide the planning reference number. We will ask you for a building control reference to evidence formal commencement at the site.

Developments without planning permission and building regulation approval will not be addressed due to the risk of the development being removed.

When applying you must include a: 

  • location plan clearly outlining the extent of the development in relation to existing streets and landmarks
  • site layout plan showing all plot numbers, means of access, locations of front doors and road junction priorities

For developments that are subdivided into units (e.g. block of flats, or a dwelling into flats), you must provide internal layout plans showing the location of the main entrance, floor number, plot numbers and whether each internal property has its own letterbox or if there will be a bank of letterboxes for the block.
