New Appointments are made where a limited company is appointed by Ofwat to provide water and/or sewerage services for a specific geographic area.

Variations are created when an existing appointed company asks Ofwat to vary its Appointment so that it can extend the areas it provides services to.

A NAV is a water and/or wastewater provider in its own right and replaces the statutory water company in the area or areas for which Ofwat grants an application. They have the same duties and responsibilities as the previous company.

A site will be eligible for applying for a new appointment and variation if it's:

  • unserved;
  • for a large user; or
  • given consent by the incumbent water and/or sewerage company.
