New Appointment and Variation (NAVs) are companies that have successfully applied to become a new service provider within an existing water company’s region.
This means they can provide wholesale water and/or sewerage services for a specific area, typically for a new or large development.
You can ask a NAV to serve your development in a defined area known as an inset. If you choose a NAV to supply your water and/or wastewater services, they will own and maintain the network of your development.
