Street naming and numbering
We are responsible for the naming and numbering of new or existing streets and buildings within the borough boundaries. We carry out these functions under the London Government Act 1963 and London Building Acts (Amendment) Act 1939.
You will need to submit an application to us if you wish to name or number a new development, sub-divide an existing property, or change the name or number(s) of an existing property or development.
All new numbers or names for streets or buildings will be considered against our procedure on Street Naming and Numbering. The policy is designed to minimise the chance of any confusion in emergency situations, by preventing address duplications or similarities in the local area, including neighbouring boroughs.
We will consult with Royal Mail to allocate a postcode or postcodes. This process can take between one and two weeks. Please note that utility companies and other private companies which provide services, will generally not carry out these services until the address is included on the Post Office Address File (PAF). The Royal Mail will not add addresses to PAF until they receive the required information from us. We therefore advise you to contact us at the earliest stage of a proposal, preferably when building works commence, and before a name has been marketed.
You will need to contact us if you need to do any of the following:
- Name/number new building(s)
- Sub-divide an existing building (s)
- Name new streets and pathways
- Re-name existing streets and building(s)
- Re-numbering of building(s)
All approved new or amended addresses are subsequently sent to the Emergency Services, Royal Mail, Land Registry, Ordnance Survey, The Valuation Office, and Council Departments such as Electoral Registration and Council Tax.

Please note contravention of the Street Naming and Numbering provisions may result in a prosecution under Section 15 of the London Building Acts (Amendment) Act 1939.
Following receipt of your application we will:
- Inform you within 2 days if the proposal is not consistent with our policy and invite you to consider alternative suggestions
- Consult with Royal Mail and Ward Councillors’, where appropriate, on your proposal and inform you of the outcome within 10 days
We undertake all necessary consultations with Royal Mail in connection with the provision of new addresses, or any alteration to an existing address and following agreement of the proposals, will notify the Emergency Services and other relevant public bodies.
Other notifications of the change are supplied via the Local Land and Property Gazetteer (LLPG) and the National Land and Property Gazetteer (NLPG) to ensure that correct addresses are properly recognised.
