KBC Bank Ireland are set to cut their variable mortgage interest rates for new and existing customers.
When the bank announced a rate cut last month, only customers taking out a mortgage for the first time benefited.
Now the bank is to cut its variable rate by 0.25pc for all mortgage holders. This will take it down to 4.25pc.
Customers who have their salary paid into a KBC current account get a further mortgage rate discount, which will mean they will get a variable rate of 4.05pc.
The reduction will take effect from December 1.
A mortgage customer with a €200,000 loan over 25 years will see payments going down by around €30 a month.
The reduction is the first since KBC and five other banks had meetings with Finance Minister Michael Noonan about high mortgage charges.
Up to now only AIB, and its subsidiary EBS, had responded to previous calls from Mr Noonan for lower variable rates.
Others, such as Bank of Ireland, have reduced their fixed rates but left variable rates unchanged.
And selected variable-rate customers of Permanent TSB, and Ulster Bank can benefit from lower interest rates if they have built up equity in their homes.
Permanent TSB has written to 70,000 customers telling them about its new managed variable rates.
Reductions of as low as 0.8pc are on offer, but only for those with small mortgages relative to the value of the home.
Last month Ulster Bank also announced a series of cuts. The reductions will benefit those with equity in their homes. In other words, those with a low loan to value (LTV).
Ulster Bank customers with a LTV of between 60pc and 80pc can now get a rate of 3.7pc. This compares with 3.9pc previously.
