To calculate the cost of supplying services to a potential customer within the Welsh Water supply area, see our published charges for our wholesale services.
 
The Wholesale Charging Rules require each undertaker considering significant changes to its Primary Charges, to publish information informing stakeholders of the scope of its proposed changes no later than six months before publishing its final charges.

Wholesale Industrial Tariffs – Charges for 2020/21

In accordance with information requirement A2 of Ofwat’s rules for wholesale charging, confirmed in the letter to Regulation Directors of 14 June 2019:

 -  We confirm that, based on the plan that we have submitted for PR19, we do not anticipate any significant increases to wholesale water primary charges applicable to Eligible Sites for 2020/21.
 -  We are not proposing to change the structure of any of the primary charges applicable to Eligible Sites for 2020/21. 

The above statements are made on our reasonable expectations for wholesale water charges for 2020/21. However, there is greater uncertainty around the scope for any changes for this year due to the Company not being in a position to know the results of the price review process at this time.
