Charges and billing
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.
In accordance with information requirement A2 of Ofwat’s rules for wholesale charging:
- We confirm that we do not anticipate any significant increases to wholesale water primary charges applicable to Eligible Sites for 2022/23.
- We are not proposing to change the structure of any of the primary charges applicable to Eligible Sites for 2022/23.
The above statements are made on our reasonable expectations for wholesale water charges for 2022/23 at this time, although we note that there is uncertainty as to the level of November CPI(H) which could materially affect the charges.
