The move follows a similar commitment from Electric Ireland
A second energy supplier has announced a winter price freeze, despite concerns over rising wholesale costs.
PrepayPower says electricity and gas prices will remain unchanged for its more than 200,000 customers over the coming months.
The move follows a similar commitment from Electric Ireland, which announced its freeze back in July.
It has announced the move despite rising wholesale energy costs and concerns over European gas supplies.
It's the second winter in a row the company has committed to keeping prices unchanged.
The company says the decision will give customers some certainty as they plan their household budgets over the coming months.
However, PrepayPower's decision comes just months after it increased electricity bills by almost 9 per cent and gas bills by more than 10 per cent.
