Applying for new postal addresses
It is important to apply for a postal address as early as possible, ideally, as soon as planning permission has been granted. Utility companies may be reluctant to connect services to properties that do not have official postal addresses, and it may be important to secure addresses for marketing and sales purposes. Obtaining a new postal address may involve naming new roads. This can take time to agree and can cause problems with sales if the process is not begun early enough.
Local authorities have statutory responsibility for naming streets and numbering properties. Applications are generally made to the Local Land and Property Gazetteer (LLPG) team or the Street Naming and Numbering (SNN) team.
A postal address may be applied for by individuals or developers by completing an application form (or sometimes by writing a letter or emailing the local authority) and may need to be accompanied by a drawing showing the extent of the premises, and relevant planning permissions. A fee is chargeable for applications.
If the application is approved, an approval notice will be sent to the applicant confirming the addresses, with a drawing show any agreed new streets and property numbers. Details will also be issued by the local authority to the emergency services, statutory authorities and the Royal Mail, who are responsible for allocating postcodes.
New addresses are allocated in accordance with British Standard 7666 and are compiled and recorded by the National Land and Property Gazetteer (NLPG).
