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