Statistician's Comment
The Central Statistics Office (CSO) has today (11 June 2026) published the Consumer Price Index (CPI) May 2026.
Commenting on the release, Anthony Dawson, Statistician in the Prices Division, said: “Today’s release of the CPI shows that prices for consumer goods and services in May 2026 rose by 3.6% on average when compared with May 2025.
Annual Changes
The most significant increases in the 12 months to May 2026 were seen in Education Services (+8.9%) and Clothing & Footwear (+7.4%). The annual change in Education Services reflects a rise in costs associated with third-level education which came into effect from October 2025. The rise in Clothing & Footwear was due to higher prices for garments and footwear.
Furnishings, Household Equipment & Routine Household Maintenance (-0.6%) was the only division to show a decline when compared with May 2025.
Monthly Changes
Consumer prices in May 2026 fell by 0.1% in the month. This compares with an unchanged monthly index figure in May 2025. In May 2026, the most significant monthly decreases were in Recreation, Sport & Culture (-2.6%) and Housing, Water, Electricity, Gas & Other Fuels (-1.1%). The fall in Recreation, Sport & Culture prices was primarily due to lower costs for package holidays. Housing, Water, Electricity, Gas & Other Fuels fell mainly due to lower costs for home heating oil.
The largest monthly increases were in Clothing & Footwear (+1.2%) and Insurance & Financial Services (+0.8%).
It should be noted that these figures relate to the CPI. The Flash Estimate Press Statement published on 29 May 2026 related to the EU Harmonised Index of Consumer Prices (HICP).
