I moved from Scotland to Finland, so I guess I'm familiar with the UK temperatures ranges!
I'm generally one of those people who is always warm, so with that caveat inmind I don't find -10 to be too difficult. I can travel to the office, or shops and back with jeans, t-shirt a hat and a decent jacket.
It's only when things get colder than -15 or so that I need gloves, a scarf, and more layers. That's the kinda temperature where your face starts to hurt when you're outdoors, and daily life gets unpleasant. You start to think "Maybe I'll go to the shop tomorrow", and plan things so that you don't have to go outdoors like that.

You and me both! Here in Canada it can easily reach -30 and I go out with tank tops. I have a theory that if you can control your inner temperature, you won't feel cold, so it's an intrinsic thing. Although some of my colleagues exploited this when we used to go to the field to fly and test drones during harsh winter, they would bring up that theory to me to be outside while they were cozying up in the car!
