Iberdrola Ireland has become the latest energy provider here to increase its household gas and electricity charges.
The company said its gas customers will see their average bill rise by 11%, adding around €12 to a bill.
While electricity customers will see charges increase by 24%, driving the average bill €33 higher.
The changes will take effect from May 5.
"We're having to respond to the unprecedented conditions in the global energy market," said Sean O’Loughlin, Head of Iberdrola Ireland.
"We remain committed to providing our customers with a quality and best value service, and that is something we take very seriously."
The provider said that customers will be contacted about the upcoming changes and support and guidance would be provided to customers who may be worrying about the changes or struggling to pay their energy bills.
It added that customers on discounted tariffs will continue to receive their current level of discount.
Last week, Electric Ireland said it will increase its residential electricity prices by 23.4% and gas prices by 24.8% from 1 May.
While Bord Gáis Energy also said last month that its average electricity bill will go up by 27% and the average gas bill will go up by 39%.
Energia and PrePayPower have all also recently announced price hikes.
