New Appointments and Variations

Full Service NAVs

We welcome early discussions with NAVs to consider on a case by case basis any efficiency savings achieved by a site being served via a full service NAV. We intend to review each application on a case by case basis to establish as a matter of fact what costs have been avoided for the business as incumbent supplier, and whether it is appropriate to give credit for these costs (to ensure an appropriate profit margin is available for the NAV making the application).

NAV Applications

NAV Applications within our area are managed by our Wholesale Service Centre. All enquiries and form submissions should be made to telephone number 0800 2605053.

We have a suite of documents to assist new NAV Applications:
