The UK base rate is 5.25%.
From the table above, savers in the UK can get retail savings rates greater than the base rate.
The base rate in the EZ is 4% or 4.5%.
In Ireland, in the domestic market (not Raisin), I have not checked, but I'd say 3% is the max?
So, as is often the case, the lack of competition here leads to worse value.
