Street naming and numbering

Organisations, postal and emergency services, and the general public, need an efficient means of referencing and locating properties, so the address of a property is an important issue. 

We are the street naming and numbering authority for the Dacorum area. The address management service provides the principal point of contact for all address issues. These include:

  • Addresses for new developments and properties
  • Change of house name
  • Adding a house name to a numbered address
  • Renaming streets and renumbering properties
  • Address problems and queries
  • Cleansing the Local Land and Property Gazetteer

New property

If you are a developer of a new property, you should contact the Address Management section as soon as you start work on site.

A single property or small development will usually be named and numbered into the existing street. A larger development will require a new development and/or street name.

Once the address issued, the information is sent to all public utilities, emergency services, HM Land Registry, Hertfordshire County Council and all our relevant departments. You will also be sent a copy of the registered address from which we would ask you to inform your prospective purchasers of their new property address.


Once we've received your application, we will begin processing your development / name / numbering requests. Please see table below for charges.
