Street Naming & Numbering

If you are building a house, converting a property, or developing commercial and industrial properties, you need to create the new address through us, we will then register it and then pass this information to Royal Mail. If not you could have problems receiving post, obtaining services like broadband or receive help from emergency services should you need it.

Please note can all issues with Street Naming and Numbering be sent to our email

The Council has a legal duty to carry out the statutory function of Street Naming and Numbering under The Towns Improvement Clauses Act 1847 used together with section 21 of the Public Health Acts Amendment 1907.

All types of developments are subject to the formal SNN process, including all residential, commercial and industrial properties.  So please get in touch to let us know the details of your development.

Why is Street Naming and Numbering important?

Street Naming and Numbering is essential for:

  • Helping the public find buildings easily;

  • Efficient delivery of post;

  • Fast responses to emergencies by ambulance, police, and fire services;

  • Record-keeping of legal transactions, taxation, planning data, etc.

Please get in touch with us if you need the following


  • Street names - if you are a developer, building a large development that you think will include new streets, please contact us prior to the start of construction.
  • A house number for a newly-built property that you have moved into (though please, whenever possible, contact us when construction starts, rather than when construction is complete - obviously we understand that this is not your fault if you are not the builder/developer).
  • A house number if you have moved into a property that you think may not have one - e.g. because you have experienced problems when trying to obtain services or deliveries.
  • A flat number if a house has been converted into flats or if an existing shop has had a flat converted above it - or similar scenarios.
  • A property name for a property if your existing property has a name only (this is rare and will usually only occur because there are no numbered properties on your street) and you wish to change it, though we will look to see if it is possible to allocate a number (e.g. if your street has existing numbered properties on it)
  • If you have looked up your postcode or address on Royal Mail's website and cannot find it.
  • If you have moved into a property and don't know what the address is.


  • A property number for a commercial building
  • New numbers because you are splitting down or merging commercial units.
  • A property number for a commercial building, if you move into one that appears to be using the previous business name as the address.  If you just start using your own business name as the address no other organisation will know that you are doing this.  You must contact the Street Naming and Numbering Officer at the Council to apply for a building number.
  • Numbers for suites of offices within an office block, if the building is subdivided.

Other considerations

  • Please note Royal Mail do not make addresses for new properties, this is the duty of the Street Naming and Numbering section at the Council.  Once we have made an address we then pass this to all relevant departments in the Council and Royal Mail.  So please contact us first and wherever possible before the development has been built.
  • We have no objection to a house name being used as part of an existing postal address, but it cannot replace the street number, which must always be used and will not be part of your official address.
  • The house name will not be a formal part of your address if the property has a number.
  • Street numbers and building names should always be prominently displayed where they can be easily read from the public highway.  Where the property is at some distance from the public road, the number/name should also be displayed at the access point to the property.
  • It can cause considerable delays agreeing a street name that both the Council and the applicant are satisfied with.  The Council appreciates street name suggestions being put forward, especially as the applicant is often the person who knows the local history of the site best.  However, the Council has a responsibility to create names that are as sensible and unambiguous as possible and therefore requests that as many name suggestions as possible (e.g. 8 - 10) are put forward but that each applicant is aware that the Council will ultimately decide the street name in accordance with its statutory powers.
  • We ask that you consider the time spent on having to manually 'clean-up' plans supplied to us when they are cluttered with measurements, drainage details etc., and try to ensure that plans you supply to us clearly show the layout of the new properties overlaid onto the Ordnance Survey Master Map layer, with no additional information such as measurements etc.
