Working with a NAV
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.
To find out more about using a NAV, visit Ofwat’s website.
If you’re an inset company (an organisation with a licence variation to supply water within our network), we’ll work with you and do everything we can to make your development a success.
