Currently switching my mortgage to them from KBC. AIB offered better rate in the meantime since I started mortgage switching process, but tempted to progress forward with UBank which I would suspect should lower rate to align with market soon, unless there is a negative impact of Brexit that would prevent them from dropping rate.
I am already quite advanced in the process with Ulster Bank. My thinking is to continue with them, and then potentially switch again next year if the rates don't drop. There is no clawback on their 1500 euros offers from what I see.
