Bord Gáis Energy Announces 9.1% Price Hike from October Adding €317 to Dual-Fuel Household Bills
Bord Gáis Energy has announced significant price increases for residential gas and electricity customers effective October 9, 2026, with typical dual-fuel households facing an average annual bill increase of €317 — the latest blow to Irish household budgets as wholesale energy market volatility driven by geopolitical tensions continues to feed through into consumer prices.
Background
Bord Gáis Energy is one of Ireland's largest energy suppliers, serving hundreds of thousands of residential and business customers across the Republic. The company, which is owned by Centrica, has been navigating a challenging energy market environment since 2022, when the Russian invasion of Ukraine triggered a sharp rise in wholesale gas prices that forced suppliers across Europe to implement significant price increases.
Irish households experienced some of the sharpest energy price increases in the EU during 2022 and 2023, with the government responding through a series of energy credits that provided temporary relief to consumers. Those credits have since been wound down, leaving households more exposed to the underlying market dynamics. The current round of price increases reflects a new phase of wholesale market volatility driven primarily by the conflict in the Middle East and its impact on global energy supply chains.
The announcement from Bord Gáis is particularly significant because it includes the first gas price increase from the company in four years. Gas prices had moderated significantly from their 2022 peaks, and the return of upward pressure on gas costs signals a deterioration in the wholesale market environment that is likely to affect other suppliers as well.
Key Developments
The price changes, announced on September 9 and taking effect on October 9, are detailed as follows. Electricity unit rates will increase by 9.1%, with standing charges rising by 7.2%, resulting in an 8.8% increase in the typical annual electricity bill — approximately €177 per year or €14.75 per month. Gas unit rates will increase by 10.6%, with standing charges rising by 7%, resulting in a 9.3% increase in the typical annual gas bill — approximately €140 per year or €11.67 per month.
For dual-fuel customers using both electricity and gas, the combined annual bill increase is €317, or €26.42 per month. Customers on the Smart Dynamic Tariff will face a 13.7% increase in the base unit rate, with a 4.7% rise in the standing charge.
The company has noted that the price adjustments coincide with a reduction in the Public Service Obligation (PSO) levy on electricity bills, which decreases to €0.51 (excluding VAT) per month effective October 1 — a partial offset to the price increases. Customers have the right to terminate their contracts within 30 days of the September 9 announcement if they wish to switch to a different supplier.
Why It Matters
The Bord Gáis announcement is the most significant energy price increase in the Republic of Ireland since the government wound down its energy credit scheme, and it arrives at a moment when household budgets are already under pressure from rising rents, food costs, and childcare expenses. The €317 annual increase for dual-fuel customers represents a meaningful additional burden for families on average and below-average incomes.
The timing — just weeks before Budget 2027 on October 6 — will intensify pressure on the government to include energy support measures in the budget package. Opposition parties, including Sinn Féin, have already called for the reintroduction of energy credits, and the Bord Gáis announcement will strengthen that argument. The government has so far resisted calls for blanket energy credits, preferring targeted supports for the most vulnerable households.
The broader energy market context is also concerning. If wholesale gas prices remain elevated through the winter — as many analysts expect, given the ongoing geopolitical situation — further price increases from other suppliers are likely. Ireland's relatively high dependence on gas for electricity generation makes the country particularly exposed to wholesale gas price volatility.
Local Impact
In Dublin, where Bord Gáis has a large customer base across the city's residential areas — from Clontarf and Drumcondra to Tallaght and Clondalkin — the price increase will be felt across a wide range of household types. Renters, who typically have less control over their energy efficiency than homeowners, are particularly exposed, as are older people living alone on fixed incomes.
In Cork, Galway, Limerick, and Waterford, where Bord Gáis also has significant market share, the impact will be similar. The company has encouraged customers experiencing financial difficulty to contact it directly to discuss support options, including flexible payment arrangements and the Energy Support Fund, which provides assistance to customers who are struggling to pay their bills.
What's Next
The new tariffs take effect on October 9. Customers will see their bills split to reflect usage at the old rates up to October 8 and usage at the new rates from October 9. Budget 2027 on October 6 will be closely watched for any energy support measures. The Commission for Regulation of Utilities is expected to publish its quarterly energy market report in October, which will provide a broader picture of price trends across the sector.
