There are still things you could possibly take to the Ombudsman as well possibly, minor things if AIB weren't forthcoming.
Not sure if this will hold water but does this judgement effectively timestamp the reduction from when you roll off your first fixed rate? So if you were someone who was close to your LTV 80% presently, then once this change is put across, then theoretically you would have hit your 80% a few years ago so you could raise a question (I may need to research this, it could be completely off the wall!!!) as to whether it would have been appropriate to retrospectively avail of LTV discounts. Maybe this would be like a nuisance case for the FSPO and something AIB might need to consider. It wouldn't be huge reward financially but maybe there is a point somewhere in the above.
Anyhow, this is all in a vacuum at the mo until we see the final redress and FSPO decision.
