@Mort.Switcher22 After thinking about this some more, I feel like nothing less than the following would amount to fair redress:
- KBC should, with your agreement, put you on a 1.95% fixed rate now (with about 6.5 years left to run on the fixed period)
- They should compensate you to the tune of the amount of extra interest you have paid over the last 6 months or so, plus the €1,500 switching contribution that Avant were offering (but minus the fees you would have had to pay for switching)
- They (and Bank of Ireland when they take over your mortgage) should offer you the fixed rates that Avant offer – from now until the very end of your mortgage term
- They should also offer you all of the other benefits that Avant mortgage customers get (large overpayments without penalty, the waiving of break fees if you trade up, etc.)
This type of redress would mean that it were as if you had made the switch to Avant earlier in the year, and you would not miss out on any of the associated benefits over the coming years.
