Darragh O’Brien has told people that their energy bills will "plummet" if they take advantage of the Government’s increased grants for retrofitting. AdvertisementHowever, many homeowners lack the money to invest in the retrofitting measures that reduce both bills and carbon emissions. Since 2019, close to a quarter of a million Irish homes have claimed SEAI grants to retrofit their properties, cutting both bills and carbon emissions. “It is working,” Minister O’Brien added. “They're a very climate friendly and efficient way of heating one's house and also very cheap in relation to ongoing bills, I've effectively doubled the heat pump grant,” Minister O’Brien said.
