Nearly half a million Bord Gais customers face a potential 22pc hike in their gas bills from October following approval for an increase from the energy regulator.
The gas company had originally sought a 28pc increase due to the cost of wholesale gas on international markets.
But the Commission for Energy Regulation (CER) has proposed a lower increase after it did not accept some cost requests by Bord Gais, including those related to bad debts.
The regulator said the planned increase is 'unavoidable' considering current market conditions while it also regretted the decision..
CER will make a final decision on the gas increase in late August, after a period of consultation.
