Privacy notice street naming numbering

Our street naming numbering privacy notice explains how we use your personal information and tells you about your privacy rights and how the law protects you.

Information we collect

We will ask for the address of the site that needs addressing as well as the address you would like your confirmation letter sent to (if different). If the property is under construction, has only recently been constructed or if it’s a conversion we will also need to see plans of the site. You can choose to tell us your name and give a contact telephone number or email address. 

Why we collect this information

We need to have the correct address details to keep our Local Land and Property Gazetteer up-to-date. Information from our Gazetteer is fed into the National Addressing Database which is used nationwide to provide our day-to-day services such as water, sewage, electricity, gas, telecommunication as well as to co-ordinate the emergency services if needed.

We send a confirmation letter of the addressing change for you to keep with the deeds to the property. This is important if you want to sell or transfer ownership to someone else.

For newly built properties, properties under construction and conversions we ask for site plans so we can be sure we have the correct property and location.

You have the option to tell us your name and contact details so we can contact you more quickly if there’s a problem or we need more information. You don’t have to give these details – we can still process your request without them.

Who we might share your information with

Non-personal information about the addressing change will be shared with other internal departments including council tax, planning, building control, cleansing and elections. Teams at West Sussex County Council are informed, including Land Charges, Highways and the Schools Admission Team. We will also notify Royal Mail, Ordnance Survey, Land Registry.

We will not share your name or contact details with anyone.

What we do with your information

We will update our Local Land and Property Gazetteer and send you confirmation that the change has been made.

How long we keep your information

We will keep your request for five years.
