Ah yes, had a good chuckle recently at banks now charging 40% for pre-arranged overdraft.
Mortgage rates 4% (comparison sites will show lower because they all use an introductory period figure).
Savings? Go for five year deposit with a bank you've never heard of before and you might hit 2%. Much more likely 1.5%, anything with on-demand withdrawal will be 0.5% or less.
Personal banking is a side-show for most of these companies. People have to have it, so they can charge what they like.
