Electric Ireland customers warned of data breach risk

Release Date: 08-November-2023


Electric Ireland one of the largest energy suppliers in Ireland, has confirmed that about 8,000 of its 1.1 million residential customer accounts may have been compromised by a data breach. The company said that an employee of a contractor working on its behalf may have inappropriately accessed the customer accounts, leading to the potential misuse of personal and financial information.

The data breach was discovered last week and Electric Ireland has written to all potentially affected customers to inform them of the issue and provide advice on how to protect themselves from possible fraud. The company said that customers who have not received a letter from Electric Ireland do not need to worry, as their accounts are not impacted by the breach. 


The data breach may have exposed customers’ bank account numbers, debit and credit card details, and IBAN numbers.


Electric Ireland advised customers who received a letter to check their bank statements for any unusual activity going back to October 2021, and to contact the company and the gardaí if they notice any suspicious transactions. Customers affected will need to cancel their debit and credit cards and change their passwords.


Electric Ireland said that it is cooperating with the gardaí and the Data Protection Commissioner to investigate the breach and prevent any further incidents. The company also said that it takes the security and privacy of its customers very seriously and that it is taking all necessary steps to ensure that such a breach does not happen again.


Electric Ireland apologised to its customers for the inconvenience and concern caused by the breach and assured them that it is working hard to resolve the issue as quickly as possible. The company also urged customers to be vigilant and to report any suspicious emails, phone calls, or texts claiming to be from Electric Ireland or other organisations.
