Gas customers look set to see an increase in their bills next Autumn.

A spokesman for the Commission for Energy Regulation said that a rise is likely and a figure of 10% is a rough estimate.

He said there is upward pressure on gas prices and that the exchange rate between euro and sterling is a significant factor - 93% of the gas used here comes from the UK

Bord Gáis is due to make a submission to the Commission shortly. A spokeswoman said the company is still finalising its proposal.

The Commission for Energy Regulation is due to publish its consultation paper in July. Any price increase would come into effect on October 1.

Although only Bord Gáis tariffs are still set by the regulator, other gas suppliers such as the ESB and Airtricity usually track these closely.
