Information for new appointees (NAVs) on prices for the supply of bulk services

Bulk Supply charging arrangements for 2021-22

At the end of January 2021, we published our latest Wholesale Charges Scheme for 2021-22. The wholesale charges are an integral component of how we set our charges for the supply of bulk water and wastewater services for NAVs.

We have updated our Bulk Supply Pricing Model for NAVs for 2021-22. The model enables NAVs to produce bulk supply and discharge tariff information relevant to their development site opportunities. The model can be used by NAVs ahead of engaging formally with Yorkshire Water to arrange a bulk supply and/or discharge agreement.  With the provision of some basic site-specific information, as a NAV you will be able to assess the bulk tariff information in an easy to use format.

We also provide an explanatory document for 2021-22 detailing our approach to setting bulk supply charges for NAVs and the updates made from our charges between 2020-21 and 2021-22.

The 2021-22 model is available to download and use below.

If you have any questions regarding the use of the pricing model, please contact:

Our consultation on NAV Bulk Supply charging

In February 2019, we published our New Appointments and Variations (NAVs) Bulk Supply charging for consultation. This set out our updated bulk supply charging policy and how it aligns with the regulatory guidance and the wider context set by Government. The bulk charges covered by this consultation only relate to bulk supplies from Yorkshire Water to a NAV. The consultation document can be found in the supporting documents lower down this page.

In April 2019 we published the results of the consultation regarding our approach to pricing for the provision of bulk supply services to NAV’s in the region served by Yorkshire Water, and we wanted to take this opportunity to provide you with an update on our progress. The results to the consultation are available to download lower down this page.

Our aim throughout the development process has been to ensure that our bulk supply charging approach and model enables fairness and transparency for all NAV’s, and we believe we have achieved this objective. We have now had the opportunity to consider all the feedback we received through the consultation exercise and we thank all participants for their valued input.

Although the consultation has closed, we would welcome your feedback on our Bulk Supply Pricing Policy and the Bulk Supply Pricing Model. Please send us your comments using the contact details below.
