New Appointments and Variations (NAV)

What is a NAV?

New appointments and variations (NAVs) are limited companies who can be appointed to provide a water and/or sewerage service to customers in an area which was previously provided by the incumbent monopoly provider.

These companies are appointed by Ofwat and have the same duties and responsibilities as any other statutory water company. For more information on becoming a NAV, or this application type please see guidance published on OfWat’s website.

Generally, a NAV can be granted in a few situations:

  • The area is considered ‘unserved’ i.e. no properties in the area are served by a current appointed company.
  • The current appointed company consents to transfer an area.
  • A large demand of at least 50 mega litres of water per year

Our process guidance for this application type is detailed below. We have a team dedicated to NAVs as we understand the importance of getting this right without any delay. For more information, please get in touch with our team on 0345 357 2428.

Details on our specific NAV charges can be found here.

Site Status Confirmation

If you are applying under the “unserved” criteria you’ll need confirmation from us of the served status of a site. This will support your application to OfWat. In order to do this you’ll need to send us a site location plan showing the site boundary (on an OS background). On occupied sites, if there are existing premises within the proposed NAV boundary, please provide any available details of the occupant & plans for future supply.

Enquiries should be made through our online portal and once received a member of our team will check our records and respond to you within 21 days.

NAV Application

When it comes to making a full application you’ll need to you’ll need to send us a site location plan showing the site boundary (.dwg format with an OS background) and the demand information for the proposed site. We’ll complete the necessary assessments to understand the impact of the proposed development on our network and provide a report outlining;

  • the cost of providing a bulk connection to your site,
  • capacity availability and constraints,
  • information on any reinforcement works (where applicable) and;
  • details of any infrastructure charges, credits and income offset applicable to your site.

You can submit your enquiry through our online portal and once received a member of our team will be in touch to discuss your site. We will then complete the necessary assessments and issue a report to you within 28 days.

At this stage, to make things a bit easier we will issue draft bulk agreement terms for your review.

Bulk Supply Agreement

When you’re ready to move forward we’ll (both parties) need to enter into the bulk water agreement for your site. This outlines the details of the supply and general arrangement between us for the site. Ofwat will not grant the new appointment or variation without this being in place, so it’s an important step.

The draft terms for this are provided at an earlier stage, so this step should be relatively straight forward. We aim to get this standard agreement to you well within 28 days.

Bulk Water Connection

When you are ready for your bulk water connection you will need to make the necessary payments and get in touch with us to discuss the work and agree programme dates. We will work with you throughout this stage of the process to ensure it all goes smoothly.

Depending upon the work we are undertaking this can take up to 90 days however we’ll do what we can to meet your programme needs. If there are any third-party constraints (ie a Road Closure) that may delay us we’ll let you know.

We have prepared a document that sets out our charges to NAVs, which you can open or download here. If you have any comments on our charges document then please click here to email us your comments.
