Hi @Eoghan
I understand your thinking. However with KBC you can overpay by 10% of the initial balance during the fixed period without incurring a break fee. So for example if you've a 400k mortgage and fix for 3 years, you can overpay by 40k during the 3 years (before a break fee is calculated).
With Ulster Bank you can overpay by 10% per year (of the starting balance for that year). So using details above 40j in year 1, 36k in year 2, etc.
Personally, with the banks that give this flexibility, I don't think you need to split with the variable on a more expensive rate.
