HUNDREDS of thousands of householders are facing a €300 hike in their annual energy bills, the Irish Independent has learned.
Bord Gais will this week announce it is pushing up the cost of its electricity by between 10pc and 14pc.
And in further pain for its residential customers, the energy supplier is also seeking permission to increase its gas prices by up to 28pc. This will mean an increase of €120 on the average family annual electricity bill and €200 on the annual gas bill.
Consumer watchdogs last night condemned the move to raise electricity prices, accusing the semi-state company of "hoodwinking" customers into switching from rival suppliers.
Hundreds of thousands of consumers changed over to Bord Gais for their electricity supply over the past two years after a high-profile advertising campaign urged householders to "make the big switch" on the promise of paying lower prices.
The hike in electricity prices will add around €120 to the average annual bill of €1,000 for a family. The higher price is to take effect in October.
Bord Gais has also asked the energy regulator for permission to push up its gas prices by up to 28pc.
An increase of this size would result in the annual average bill of €737 for a family going up by around €200 to close to €1,000. The company has more than half a million gas customers.
