Irish households and businesses are facing a renewed round of energy price increases this autumn, with all major suppliers announcing higher gas and electricity rates within weeks of each other. The scale and timing of the rises — arriving just as the Government finalises Budget 2027 — mark one of the most concentrated periods of energy cost pressure since the immediate aftermath of the Ukraine invasion in 2022.
The increases, supplier by supplier
Bord Gáis Energy, the country's largest gas supplier with around 300,000 gas customers and over 400,000 electricity customers, confirmed on 9 September that unit rates and standing charges will rise from 9 October. A typical electricity customer's bill will increase by 8.8%, or €177 a year, while a typical gas customer's bill will rise by 9.3%, or €140 a year — a combined dual-fuel increase of 9.1%, or €317 annually. Director of Customer and Commercial at Bord Gáis Energy, Catherine Lonergan, said the company recognised "this announcement will be unwelcome for customers," adding that increasing prices "is never a decision taken lightly."
Energia followed with its own increase from 12 October: a 4.73% rise to average annual electricity bills (€1.67 a week) and a 9.38% rise to average annual gas bills (€2.74 a week), with combined dual-fuel customers facing a 6.73% increase, or €4.41 a week. Electric Ireland had already moved earlier in the year, raising residential electricity prices by 8% and gas prices by 7.7% from 1 July — its first price increase since October 2022, a gap during which the company said it had delivered three gas price reductions, two electricity price reductions, and froze prices for 1.1 million customers over the previous winter. On 11 September, Energia announced a further increase that will add approximately €230 a year to a typical dual-fuel household's bill, with domestic gas prices rising by almost 10% and electricity by close to 5%.
At the pumps, prices have followed a similar trajectory. AA Ireland's monitoring shows petrol and diesel prices climbing steadily through the year, with Taoiseach Micheál Martin warning that pump prices above €2 a litre are likely to become what he described as the "new norm," citing advice from the State's own energy expert group.
Why this is happening: the global picture
The immediate trigger cited by government and industry sources alike is the conflict in the Middle East. Wholesale electricity prices in Ireland hit €179.10 per megawatt hour in March 2026, according to figures from Wind Energy Ireland, spiking after the United States and Israel's attack on Iran closed the Strait of Hormuz — the shipping route for roughly 20% of the world's oil — and disrupted liquefied natural gas production in the Gulf. That spike followed a cold European winter that had already left the continent's gas storage levels below normal.
Minister for Climate, Energy and the Environment Darragh O'Brien has been direct about the cause and its persistence, telling the Irish Examiner that "the reality of the energy cost environment that we're in now — mainly due to the conflict in the Middle East — prices are going to remain elevated for the foreseeable future." He noted that home heating oil alone has risen 59% over the past 12 months. Speaking separately to The Journal, O'Brien said the outlook points to current price levels persisting for the next 12 to 24 months, adding: "Even if the crisis in the Middle East ended tomorrow... the premium now, the risk premium on refined products, has increased. So we're going to see these elevated prices for some time to come."
Structural factors compound the geopolitical shock. Ireland's electricity generation is unusually dependent on natural gas, which fuels over a third of the country's electricity supply, leaving retail prices closely tied to international gas markets. An ESRI report published in April found the gap between wholesale and retail electricity prices in Ireland was the highest in Europe in 2024, with wholesale prices around €100 per megawatt hour against retail prices of roughly €300. Ibec has separately warned that Ireland's high dependence on natural gas, slower pace of renewable delivery, and low levels of international grid interconnection leave the country more exposed to this volatility than many EU peers, with a 2024 BusinessEurope study projecting Europe's energy costs could run at least 50% higher than the US, China and India by 2050 without policy change.
What business groups are saying
Ibec has called on the Government to treat the situation as an "emerging energy affordability crisis," and in its Budget 2027 submission proposed a €2 billion energy crisis contingency reserve to fund inflation-related measures, alongside a €300 million direct Exchequer subvention to reduce policy-related fixed costs on electricity bills and more than €70 million in additional enterprise decarbonisation grants and capital allowances. Ibec's submission also flagged that other countries, including Germany, are actively moving to reduce industrial energy costs to protect competitiveness — a shift it argues increases the pressure on Ireland not to fall behind.
The Government's response so far
The Government has already committed €750 million in support this year, including temporary cuts to excise duty on petrol and diesel and an extension of the fuel allowance for households at risk of energy poverty, following fuel protests and blockades by hauliers and farm contractors earlier in the year. A separate €500 million low-cost loan scheme for small and medium businesses and farm enterprises, backed by the European Investment Bank, is being brought to Cabinet by Minister for Enterprise Peter Burke and Minister for Agriculture Martin Heydon, offering loans of between €25,000 and €3 million without security requirements up to €500,000, running through to 2029.
Under Budget 2026, the Government had already reduced VAT on gas and electricity bills from 13.5% to 9%, a measure due to remain in place until 31 December 2030 at an annual cost of €254 million, worth an average of €100 a year to a household using both fuels. Minister O'Brien has said the National Energy Affordability Taskforce, established earlier this year to examine cost drivers across the energy system, is due to submit its full action plan by the end of September, ahead of October's Budget 2027. O'Brien has been candid about the limits of what further intervention can achieve, saying: "We're not going to be able to soften every increase in energy prices. We've got to help as many as we can, but we've also got to ensure that we really continue to invest in our grid and accelerate delivery of renewables."
How long this is expected to last
Government officials have been consistent in cautioning against expecting a quick resolution. O'Brien's 12-to-24-month estimate would place the earliest realistic relief in late 2027 to late 2028, contingent on both the Middle East conflict and the elevated risk premium currently priced into refined product markets. Longer term, the Government's stated strategy centres on reducing reliance on imported fossil fuels through accelerated renewable energy delivery and grid investment, alongside grants to support households and businesses in switching to solar and other lower-carbon alternatives.
What this means for Ireland
For households, the combined effect of the Bord Gáis, Energia and Electric Ireland increases means many dual-fuel customers are facing well over €300 in additional annual costs on top of earlier-year rises, even before the VAT reduction's offsetting effect is factored in. For businesses, particularly energy-intensive small firms in manufacturing, retail and hospitality, Ibec's warnings point to a genuine competitiveness risk if Irish energy costs continue to diverge from those of trading partners actively moving to shield their own industries.
The Bottom Line
The current run of price increases is driven primarily by a geopolitical shock — the Middle East conflict's disruption to global oil and gas supply — layered on top of Ireland's existing structural exposure to gas dependency and limited interconnection. Government officials have been unusually direct in signalling that meaningful relief is not imminent, with the Energy Minister's own estimate suggesting elevated prices could persist for up to two years, even as budget measures and a forthcoming national taskforce plan aim to soften, rather than reverse, the impact in the short term.
