Inevitably there will be some people who grew up with strange parents who, for some reason, not always poverty, refused to heat their homes.
But it is almost unknown for a home to have no heating source in the UK.
We were by no means rich but there was always coal for the fire, my dad got up half an hour before the rest of us to light it, so the living room was warm when we got up. There was a 2 bar electric fire for when they didn't want to light a fire.
You paid shillings into the meter, so if you ran out, you cut yourself off, but you never received a huge bill, you paid as you went along. Energy cost were still a big chunk of household expenditure.
Hot water was the immersion heater, but we only had one bath a week, Sunday night. My dad would avoid that if he thought he could get away with it!
We had a coal house ( big cupboard really) attached to the kitchen which got filled a couple of times a year.
There was no expectation of being able to wander about the house in a T shirt in the winter.
We had fire places in the bedrooms but they were never lit, if you wanted warmth in the winter you stayed in the living room. On reflection it would have made the bedrooms too stuffy, coal gives out an amazing amount of heat.
I can remember the council fitting central heating, made life easier for my dad but other than that, I never really noticed, I was either outside, in the living room or asleep in bed.
