Permanent TSB is to increase interest rates for certain new fixed rate mortgages by up to 0.5%.
Customers with existing fixed rates will not be impacted, nor will green mortgages.
The changes will take effect from Monday but customers who have an offer letter based on existing fixed rates will have until October 27 to complete drawdown at that rate, or prior to their current loan offer expiration, whichever is earlier.
The bank blamed the ongoing increase in interest rates by the European Central Bank, which yesterday added another 0.25%, bringing the total increases since last July to 4.25%.
PTSB said over the same period its fixed rates have increased by 2.21% on average.
It is the first increase in fixed rates by the bank since March.
The bank has also announced four sets of increases to deposit rates over the last 12 months.
