The annual rate of inflation rose slightly to 2.2% in April from 2.1% in March, the latest figures from the Central Statistics Office show.
Consumer prices in April, as measured by the Consumer Price Index, increased by 0.5% in the month. This compares to an increase of 0.4% in April of last year and as a result, the annual rate of inflation rose to 2.2%.
The annual rate of inflation for goods was 0.7% in April, while the corresponding rate for services was 3.7%.
In April, the price of home heating oil, electricity and mortgage interest repayments were higher, while transport costs rose by 2% as petrol and diesel became more expensive. Hotels charged higher accommodation costs while restaurants also charged more for eating out.
These increases were partially offset by a decrease in falling house and motor insurance costs, the CSO added.
