New Appointment Variations

Developers can request that a New Appointment and Variation (NAV) supplies water services to their development.

If you choose to work with a NAV to supply water and/ or waste water services, they will adopt, own and maintain your development network.

To find out more about using a NAV, visit Ofwat’s website.
