The fraudulent messages, which pretend to come from Gov.ie, claim recipients are eligible for cheaper electricity and urge them to click a link or provide personal and banking information.
In a warning posted on social media, the Department said: “We are aware of scam texts and emails claiming to be from GOV.IE about a reduced electricity bill.
“If you receive such a call, email or text, please do not engage and do not share any personal information or click on any links they send you.”
The Department also urged anyone who may have already shared sensitive details to act immediately.
“If you have shared any bank account details following a suspected scam, please contact your bank immediately.”
The scam appears to be targeting people in the aftermath of recent severe weather, with officials concerned some households may confuse the fake messages with legitimate State supports.
There is currently no “Emergency Benefit Scheme” offering reduced electricity bills, not to be confused with the Electricity Costs Emergency Benefit Scheme which gave energy credits to households in recent years.
The public are being advised to delete suspicious messages and avoid clicking links.
Anyone concerned they may have been targeted is encouraged to report the incident and contact their bank.
