Mine, for a few months under hopeless Major/Lamont, peaked at 15.75%. It was awful.It's amazing how 4% now seems high. Sadly I'm old enough to have had mortgage in the 80's when I had a 5 year deal at 8% and inflation was poor then too. How times change.
But the differences then - house prices were 1/6th of those now in Brighton and lending multiples were almost always more sensible.
