Variable rates and tracker rates remain unchanged.
Bank of Ireland is again raising its mortgage rates, but is also introducing a new deposit account for business customers.
The bank said the mortgage move follows cumulative increases of 3.5 percentage points in European Central Bank rates since July last year.
All fixed rates for new customers, and existing customers who want to lock in to a new fixed rate, are to go up by 0.5 percentage points.
This includes customers who are coming to the end of their fixed rate period and are seeking to re-fix their mortgage, and tracker rate or variable rate customers who wish to move to a fixed rate.
Variable rates and tracker rates remain unchanged.
Applicants who already have a credit approval and who draw down the mortgage by May 5 can still avail of the previous fixed rates.
