Irish Energy Arrears Rise as Costs Soar Following Ukraine Invasion

The number of households struggling to pay their energy bills in Ireland continues to climb, with almost 320,000 customers in arrears as of December 2025. This represents a nearly 20% increase compared to the same period the previous year, highlighting the ongoing impact of rising energy costs linked to Russia’s invasion of Ukraine.

Growing Debt and Customer Impact

Data released by the Commission for the Regulation of Utilities (CRU) indicates that over 50,000 more customers were behind on their energy payments at the end of last year than in December 2024. The final two months of the year saw a particularly sharp increase, with a 5% rise in arrears from November to December, reaching almost 320,000 customers.

Specifically, 26% of all domestic gas customers were in arrears in December 2025, whereas 14% of electricity customers were unable to pay their bills, either partially or in full. The average amount owed by electricity customers increased by 10% year-on-year, while gas customer debt decreased slightly by 1%.

The Ukraine Connection and Energy Costs

The surge in energy arrears is directly correlated with the sustained increase in gas and electricity prices following the Russian invasion of Ukraine four years ago. Dáil Éireann debates confirm the widespread awareness of this connection. The invasion disrupted global energy markets, leading to significant price volatility and increased costs for consumers.

CRU and Regulatory Response

The Commission for Regulation of Utilities (CRU) is the statutory body responsible for regulating the Irish energy sector. The CRU has implemented measures to protect consumers, including a ban on winter disconnections for those unable to pay their bills. Citizens Information details the CRU’s winter disconnection ban. The government is similarly exploring options to bolster energy security and domestic supply in response to the crisis.

Looking Ahead

The rising number of energy arrears presents a significant challenge for Irish households and the energy sector. Continued monitoring of the situation by the CRU, coupled with government support measures, will be crucial to mitigating the impact of high energy costs and ensuring access to essential services for all citizens.
