Naming and numbering - large developments


Larger Developments consisting of five or more properties

If you are a developer of a large estate, you should contact us as soon as you commence work on site and provide a detailed site plan clearly indicating the main access to each property together with plot numbers so that we can process the naming of any new streets and the numbering of your new properties without delay. We will check your suggested street names for duplication in the local area and forward them to Royal Mail for consultation. We will also consult with the ward member(s) if new streets are included.

When we have an agreed name, we will then register the street name/s and prepare a numbering schedule. The information is then sent to emergency services, Land Registry, Ordnance Survey and relevant council services, You will also be sent a copy of the naming and numbering schedule from which we would ask you to inform all your prospective purchasers of their new property address.

Where appropriate, you will be asked to provide street name plates to our standard design. We will provide contact details for ordering and you will be invoiced for the cost. See street name plates below.


Naming and numbering - Small developments

Small developments including single properties, conversions and infil builds,

If you are a developer of a new property (single or small development), you should contact us as soon as you commence work on site.

A single or small development will usually be named or numbered into the existing street. If the property is within a numbered road, then suffix are often used along with the adjoining number (for example 12A, 12B, 12C...).

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.


Renaming and renumbering streets

On rare occasions it becomes necessary to rename or renumber a street. This is usually only done as a last resort when one of the following applies:

• there is confusion over a street's name and/or numbering

• a group of residents are unhappy with their street name

• new properties are built in a street and there is a need for other properties to be renumbered to accommodate the new properties

• the number of named-only properties in a street is deemed to be causing confusion for visitors, the delivery or emergency services

Occupiers will be consulted and their views taken into account. Royal Mail and the relevant Town or Parish Council will also be consulted. To change a street name we will ballot the occupiers on the issue. We require at least a two-thirds majority in favour to make the change.

If you have a street naming or numbering issue, please contact streetname.numbering@hertsmere.gov.uk


Renaming a residential property

If the properties in your street are not numbered (i.e, house names only):

You must seek the council's permission to change your property name. This is required primarily to avoid having similar or same house names in the same area as this may cause confusion to Emergency Services or delivery difficulties to Royal Mail and other delivery companies. To apply for a change of name to your property please complete the relevant sub sections of our application form which can be found below under 'How do i apply'.

We will undertake a check on your proposed house name change within our address gazetteer, Where the proposed name change is satisfactory, the new house name will be registered and confirmed to you in writing. This confirmation is a legal document and should be retained for your records. If there is an issue with your preferred name, we will request an alternative.

The property name change information is then sent to Royal Mail, the Valuation Office Agency, Emergency Services and other relevant council services.

If the properties in your street are numbered then you can add an 'alias' name to the property:

 However you must continue to use the allocated postal number given for your property and not rely on the alias name.

An address format could be: Rose Cottage, 14 High Street, Any town, AA1 3AA

Adding an Alias Name to your property will only show up on certain databases at the discretion of the relevant officer receiving the final address from Hertsmere Borough Council.

Royal Mail may not add the alias name to their published Postal Address Files or their on-line database, however, correspondence from internal HBC departments will feature the alias name, as will the Electoral Registration database.

It is the responsibility of property owners to inform Land Registry of a house name change approval. The Leicester Office is responsible for applications from the Hertsmere Area. Their telephone number is; 0300 006 0411
