Ulster Bank has increased its fixed mortgage interest rates from today.
It is the latest lender here to hike rates following the recent rate rises from the European Central Bank in both December and earlier this month.
The bank which is exiting the Irish market, has increased its fixed rates by between 0.4% and 0.9%.
It did not make any changes to its variable rates.
Last June the bank stopped accepting applications for mortgages, except from existing tracker and offset customers.
For existing customers who have either applied for a fixed rate and are awaiting a loan offer or who have not yet completed their product switch, the bank said the original rates will be honoured.
Ulster Bank said customers with fixed rates expiring at the end of this March will be able to access the original rates up to the date of expiry of their current rate.
"We are announcing today a rate increase of between 0.4% and 0.9% on our two, four and seven-year fixed rate mortgages and that we will no longer offer Loyalty variable rates for sale," said Ulster Bank's Managing Director Personal Banking (Designate), Philip Duff.
"Our remaining variable rates will remain unaffected," she added.
"If customers have any queries our mortgage team are available for support and further information on 0818 210 275. Open Monday to Friday 9am-5pm (except bank holidays)."
Ulster Bank also announced that its loyalty variable rates will be removed from sale.
The loyalty variable rate has to date been available to customers who had an income mandated to an Ulster Bank current account.
"Its removal from sale will not impact those customers who already have a Loyalty variable rate mortgage," it said.
The deal comprised of non-tracker mortgage loans with a value of €6.2 billion.
€5.2 billion was migrated last November, with the remaining expected to migrate in the second quarter of this year.
Permanent TSB said the deal will see about 56,000 new residential mortgage customers move to the bank with its mortgage book increasing in size by roughly 40%.
