Transmission and Distribution Tariff Update The Commission for Regulation of Utilities has made key decisions regarding Gas Networks Ireland's allowed revenues and transmission tariffs for 2025/26. This update outlines the impact on residential gas customers, including estimates of network tariff changes and their effect on annual bills. Gas Networks Ireland’s combined transmission and distribution network tariff changes are expected to result in a modest increase in residential gas customers’ annual bills. This change is estimated to be approximately €1.28 (less than 1% per annum) for an average consumption of 11,000 kWh per year.
