AIB is hiking its mortgage interest rates, and those of its subsidiaries.
Variable rate customers at AIB will see their rate increase by 0.4% from June.
Those with variable rate homeloans from EBS and Haven will have to pay an extra 0.25%.
In a statement AIB said that it does not anticipate any further rate hikes this year.
The move will not effect those on tracker mortgages, with the ECB expected to make a further rate cut shortly to a record low of 0.5%.
