Your break fee should be zero at the moment – but it is volatile because wholesale interest rates are volatile, so confirm it with KBC (and please post it here when you receive it, including the date of the letter).
- Switching immediately to AIB's 5-year fixed rate (2.35% with €2,000 cashback) will save you about €580 over the next 4 years
- Switching immediately to Permanent TSB's 4-year fixed rate (2.05% with 2% monthly cashback) will save you about €540 over the next 4 years. (After 4 years, you will not be eligible to switch to any PTSB rate that is reserved for new customers only.)
- Switching immediately to Avant Money's 7-year fixed rate (1.95% with no cashback) will save you about €280 over the next 4 years – but with the longer security of 7 years on a fixed rate
- Switching immediately to KBC's 5-year fixed rate (2.4% with no cashback) will leave you worse off by about €190 over the next 4 years. But it is very simple and quick to do (no bank statements, salary cert or solicitor, etc., needed). You will need to open a KBC current account, however. It seems that this is still possible to do.
- Of course, if you decide to do this, you will probably want to switch again in 5 years when your fixed rate expires and your mortgage moves onto Bank of Ireland's books, at which point you will be subject to their (probably higher) interest rates
- Switching immediately to Avant Money's 10-year fixed rate (2.1% with no cashback) will leave you worse off by about €360 over the next 4 years – but with the even-longer security of 10 years on a fixed rate
These savings estimates use for comparison the scenario of switching to the 2.25% rate with KBC when the current fixed rate ends. And that's assuming that KBC (or Bank of Ireland, if they have taken over your mortgage by then) are even offering a 2.25% rate in April 2024 – it could be higher (or lower). The estimates also account for fees and any cashback offered by the above lenders.
It may seem like it is not worth switching to another lender but bear in mind that your mortgage will soon be owned by Bank of Ireland, whose rates are much higher than KBC's. So if you don't switch now, you might find that you really want to switch in a few years' time, at which point rates might be higher.
Note that the longer you fix for, the higher the break fee could potentially be in the future, which could be relevant if you want to move home. Of course, it's also possible for a future break fee to be small or zero. And at least some of Avant's fixed rates allow you to "take your mortgage with you" if you move home, which avoids any future break fee. It would be worth contacting them for clarification on which mortgages this applies to and on the terms and conditions.
Yes, the Avant cashback offer is finished. Why do you think they won't let you switch to them? If it's because a broker tells you that your balance is too low, find another broker.
As noted above, the 2.05% 4-year rate from PTSB is good over the next four years, but after that you won't be eligible to switch to their best rates – those are reserved for new customers only.
I assume that solicitors' fees are €1,300 all in and that the valuation fee is €150 or €185 (depending in the lender).
Edit: You are only eligible to switch to Permanent TSB if you have been with your current lender (KBC) for at least two years.
