New Appointments and Variations (NAVs)

The Water Industry Act 1991 incorporates legislation which makes provision for sites within an existing undertaker’s area to be served by another undertaker. Where an alternative undertaker is appointed, a NAV is made by Ofwat.

There are three circumstances in which a NAV can be granted:

  • Where the premises of one or more customers is supplied (or is likely to be supplied) with at least 50 mega litres of water per year. The same criterion applies for water recycling services.
  • Where no premises within the area are served by an appointed company i.e. the site is ‘unserved’. This includes areas which are supplied by private, unregulated supplies. This criterion has to be met for both water and water recycling services.
  • If the existing appointed company consents to the transfer of that area
The alternative supplier (the “NAV appointee”) will hold an Instrument of Appointment and therefore have all the same duties and responsibilities to the customers within the NAV appointment site as the previous statutory supplier.

Every NAV must have access to adequate water resources and/or water recycling facilities in order to service the customers on the site. If the site is within the Anglian Water statutory area of supply and the NAV does not have direct access to its own water resources and/or water recycling facilities, these services can be purchased from Anglian Water.

For water, this is purchased in the form of a bulk supply of water delivered to an agreed point, usually at the site boundary.

For used water, this is purchased in the form of a discharge point, usually at the site boundary, where bulk effluent is discharged into our water recycling system.

The supply of these services is governed by legal agreements, which are negotiated between the parties.

NAV enquiries can be submitted through our customer portal, InFlow.

Our service level is 15 business days. Where additional modelling work is required, our Pre-development team will be in contact.

NAV tariff consultation

On 8th May 2018, following a consultation process, Ofwat issued new Guidance for bulk charges from incumbent companies to NAVs. Anglian Water is now consulting with NAVs and other stakeholders on its proposals for new “NAV tariffs” to comply with this Guidance.

We have identified a number of issues in our exploration of the “wholesale-minus” calculation set out in the Guidance. Our aim with the attached paper is to test the views of NAVs and other stakeholders on our draft proposals to address these issues and to capture feedback through the questions set out in the consultation. We want to ensure that we can fully reflect upon respondents’ views and the evidence they submit before we conclude on the principles that guide our approach and the various trade-offs we have to address when we finalise our tariff proposals.

We welcome responses to this consultation by 5pm on 16th November 2018. Please send responses to NAVs@anglianwater.co.uk.

In the interests of transparency we propose to place responses on the NAV section of our website. If you wish any parts of your response to be redacted on the grounds of commercial confidentiality, please provide a version with the relevant sections blacked out.

Following receipt of responses, we intend to prepare a further document which will summarise respondents’ views on the 26 questions set out in the consultation and explain the changes to the NAV tariffs that we propose to make as a consequence. We expect to publish this four weeks after the deadline for receipt of responses.

We will then prepare the 2019/20 NAV tariffs for publication in the New Year.
