New Water Charges Go Live for Business

A new tariff framework for Irish Water’s business customers went live at the beginning of this month (Friday 1 October 2021). To assess the impact of the new charges on your business’s future bills, visit to use the online calculator tool. Further information is also available online including a detailed Q&A and case studies.
The changes were originally due to go live on 1 May 2020 but were deferred to 1 May 2021 and again to 1 October 2021, following Dublin Chamber representations that the changes ought to be deferred due to the uncertainty facing businesses under the Government’s public health guidelines due to COVID-19.


The aim of the new system is to provide a clear, transparent, and equitable charging regime for businesses regardless of their location. Currently there are over 500 different tariffs, with customers in different local authority areas paying different charges. There has been no change to charges since 2014 and in many cases much longer. The new framework will now standardise charges across the country while recovering the cost of providing water and wastewater services to non-domestic customers.


Irish Water has written to all business customers to outline what the changes meant for them, and reports that the vast majority of customers will see either a decrease or an increase of less than €250 per annum, in their annual bills.


For customers who will face larger increases in their annual bill, Irish Water will put in place a number of important support measures. Connections that see an increase of €250 or more will be transitioned to the new tariffs over 3 years.  For connections that will face an increase of €750 or more, Irish Water will automatically apply a 10% cap to their annual bill increase in any one year.
