Bord Gáis Energy has announced increases in its residential electricity and gas tariffs effective from 9 October 2026, adding more than €300 annually to energy costs for dual-fuel customers across Ireland.

Ireland's largest gas supplier confirmed that electricity unit rates will rise by 9.1% and daily standing charges will increase by 7.2%, resulting in an average 8.8% increase for residential electricity bills. According to the supplier, this equates to an additional €14.75 per month, or approximately €177 annually, based on typical household usage defined by the Commission for Regulation of Utilities.

Gas unit rates will increase by 10.6% and standing charges by 7%, raising typical household gas bills by 9.3%. The adjustment adds an estimated €11.67 per month, or €140 per year, to average gas bills. Combined, typical dual-fuel customers face an increase of €26.42 per month, or nearly €317 per year.

Bord Gáis Energy attributed the adjustments to sustained increases in energy supply costs, driven by rising national grid network charges, volatile wholesale market conditions linked to global conflicts, and general inflationary pressures. Catherine Lonergan, director of customer and commercial at Bord Gáis Energy, stated that increasing prices is never a decision taken lightly and noted that this marks the company's first gas price increase in four years.

Price comparison website Bonkers.ie noted that the decision impacts around 300,000 gas customers and an even larger number of electricity customers. Daragh Cassidy, head of communications at Bonkers.ie, observed that while the percentage hikes may appear moderate, they come on top of energy prices that remain roughly 70% to 90% higher than pre-2021 levels.

The move follows a similar price increase announced by SSE Airtricity earlier in the month and arrives ahead of the winter heating season. Under energy consumer protection rules, contract customers have 30 days from the date of the notification to exit their contract without penalty if they choose not to accept the new rates.
