Household electricity bills in Ireland are set to increase from October 1st, 2026, following the Commission for Regulation of Utilities’ approval of higher network charges. Typical domestic customers will face an estimated rise of €41.25 annually, or €3.44 per month, running through September 30th, 2027 to fund essential grid upgrades.
CRU Approves Network Revenue Allowances
Irish electricity consumers face a fresh round of bill increases starting this autumn after the Commission for Regulation of Utilities approved higher network charges to fund infrastructure development across the national grid. The regulatory decision sets network revenue allowances following the regulator’s annual review of submissions from network companies.
While the approved figures fund necessary upgrades, the totals fall short of initial requests. The regulator confirmed that the approved revenue allowances are €138 million lower than the combined total proposed by the network companies. Fergal Mulligan, chairman of the Commission, stated that the agency reviewed expenditure to ensure customers pay only for necessary and justified investment.
The CRU said it had approved lower revenue allowances than those sought by ESB Networks and EirGrid, reducing the utilities’ combined request by €138 million.
Grid Demands and Decades of Underinvestment Drive Costs
Network charges make up a significant portion of domestic energy costs, accounting for roughly 30 per cent of an end user’s overall home energy bill according to regulatory estimates, while industry observers note total grid fees and stabilization costs can push that share higher. Daragh Cassidy, head of communications at price comparison website Bonkers.ie, explained that the system suffers from historical underinvestment and must expand rapidly to accommodate modern economic demands.
The grid requires massive capital injections to cope with a rapidly growing population, an increase in the number of data centres, and the electrification of the broader economy. Furthermore, the infrastructure must expand to connect new wind farms and support renewable energy generation alongside offshore grid development and security of supply.
“Today’s decision by the CRU to approve another increase in network charges won’t be welcomed by consumers but it was largely expected as our electricity grid requires billions in investment over the coming years to cope with the demands of a rapidly growing population, an increase in the number of data centres, the electrification of the wider economy, and to help finance the transition towards Net Zero.”

Offsetting the Increase Through the PSO Levy Reduction
The upcoming network fee adjustments coincide with a significant reduction in the Public Service Obligation levy, a mandatory charge on electricity bills that funds sustainable energy projects. The regulatory body confirmed a 66 per cent reduction in the Public Service Obligation (PSO) Levy, which will lower the monthly flat fee for residential users from €1.59 down to 51 cent.
Wind Energy Ireland welcomed the adjustment, noting that CRU figures show renewable energy projects will return more than €27 million to consumers over the coming year. This reduction offers a modest financial buffer against the rising network fees, though consumer advocates caution that wholesale electricity costs have also climbed about 17 per cent year to date, leaving household budgets vulnerable to further supplier price hikes.
Political Fallout and Pressures on Households
The approved increase has drawn sharp political criticism regarding consumer affordability. Labour’s energy spokesperson, Ciarán Ahern TD, argued that households cannot face an additional €41 fee on their energy bills, pointing out that over 500,000 bills are already in arrears while Ireland maintains the highest electricity prices in the European Union according to Eurostat data.
“Households are struggling as it is to keep up the pace of the increasing cost of living from house prices and rents, the cost of food and the enormous cost of energy bills. The increase in network charges announced by the CRU today is going to push too many families to the brink.”

With government energy credits absent from the budget and wholesale energy markets showing upward pressure, analysts emphasize that consumers should actively compare tariffs. Cassidy noted that households could also face higher electricity prices if suppliers pass on rising wholesale energy costs as the October deadline approaches.
