A fair charging Framework

Uisce Éireann welcomes the CRU’s 2026 Framework decision which continues to set out a national set of water and wastewater charges (including trade effluent charges) that are transparent, and equitable for all businesses countrywide. The Framework delivers:

• An equitable set of charges which ensures that customers using the same volume of water are charged the same; and
• Charges that promote conservation by maintaining a relatively low fixed standing charges. This also provides more scope for customers to reduce their water and wastewater bills.

The application of VAT and the timing of its introduction is a matter for the Government. Water supply and wastewater collection services are currently exempt from VAT with the exception of Tankered Waste, Sludge, and Leachate.
