New Appointment & Variation
Who NAVs are and how they work?
A New Appointment and Variations (NAVs) are companies that replace another water company as the appointee for an area and provide water and/or wastewater services to customers in a defined area. According to the Water Industry Act 1991, NAVs that operate the public water and/or wastewater networks hold an “Instrument of appointment”.
In order to become a NAV, your limited company will need to go through the process to be appointed by Ofwat, so that you can serve your customers in a specific geographical area.
Here are the conditions for a limited company to be granted the NAV status:
- The company must supply water and wastewater in the order of at least 50 megalitres per year.
- The site is ‘unserved’, meaning no premises within the area are served by an appointed company. This criterion applies for both water and wastewater services.
- If the existing appointed company consents to the transfer of that area.
A NAV can choose to service its customers through its own resources, or by requesting use of our existing assets under a water ‘bulk supply’ or wastewater ‘bulk discharge’ agreement.
To find out more about finding and using a NAV, visit Ofwat’s website.
