NI Water would like to clarify that this is not a new issue, as it was widely discussed and reported upon last year. NI Water is in the process of correcting customer accounts that were identified as inaccurate. The error occurred during the transfer of customer data in preparation for non domestic billing and we are now at the stage of correcting the individual customer accounts. During this process of correction, NI Water has been completely transparent, through briefing sessions and written correspondence, to all stakeholders, including Consumer Council, Utility Regulator and the Regional Development Committee.

Customers who have been overcharged will be fully reimbursed, while those who have been undercharged will be asked to pay 50% of the undercharge. At all times, NI Water’s priority has been to ensure the fair treatment of all customers.

NI Water supplies water and wastewater treatment to over 83,000 non domestic customers, of which 7,800 have been affected.

Any customers with concerns should contact the billing enquiry line on 08458770030.”
