Well, I decided that having saving accounts that have interest of 1.2%-8% (GBP, EUR, PLN) isn't really worth it with such inflation 11-18%, so decided to fuck up years of savings and put all money into mortgage overpayments.
I did the same. My mortgage rate is low, but putting in £20k just reduced my monthly payment from £910 to £720. I see the benefit straight away on the next payment. I would put in another £20k but I would be charged a fee so I’ll wait until next year.
It will allow me to pay more into my pension and claim 20% higher rate tax relief back on that too.
