Business charges

Irish Water manages all aspects of business water accounts including billing for water services.

Important note on new charges

In line with the Commission for Regulation of Utilities (CRU) decision on non-domestic tariffs a new set of national water and wastewater business charges came into effect on the 1 October 2021.

Why were the new charges implemented?

There were over 44 different business charging regimes with over 500 different price levels across the country. As a result, customers with similar water services paid different amounts depending on their location. The Commission for Regulation of Utilities (CRU) held a number of consultations on the future water tariffs for business customers.

A final decision on the charges was published on 3 July 2019 by the CRU and it went live on 1 October 2021.

A fair charging framework

Irish Water welcomed the final decision which sets out a national set of charges that will be transparent, cost reflective, and equitable for all businesses countrywide.

Key changes are:

  • National charges as opposed to individual Local Authority charges
  • Charges which reflect the actual costs of providing water services to the business sector
  • Increases or decreases in charges for business customers depending on current charges
  • Transitional arrangements to ensure bill changes are implemented fairly and with time to plan ahead
  • Four separate tariff classes for metered connections: Bands 1 - 4

Who is affected

The new business charges will apply to both business customers and mixed-use customers who use water services for both business and domestic purposes.

Managing the changes

Transitioning customers - changes came into effect on 1 October 2021
