Gosh you're lucky this autumn. I'm in outer London which is normally a couple of degrees warmer than elsewhere, but our heating was on before August was out this year.
In response to OP, I find it super depressing when the house is cold, so take care. After a few days i notice its really making me miserable.
I think there is a bit of a competitive element to this for some reason. My mum, bless her, is a competitive cold person, but I don't think realises. It's not deliberate. Something about British stiff upper lip and stoicism. Don't ask me - I'm not someone who enjoys hardship. 🤣 I take after my dear lately departed dad. I say that without any judgement- if mum enjoys a cooler home, that's her business.
And also some people genuinely get acclimatised to cooler homes. I think mum is delighting in the freedom to enjoy a hone that feels comfortable for her after years of dad wanting it hotter during his illness. I'm not sure that's a conscious thing either - she's devastated by his death.
It throws a light on individual thermostats though. When I was obese, I was always too hot. I could happily sit in 17 degrees and still have a fan on me if it was humid.
Now I'm on a weight loss diet, I'm freezing all the time. My feet can even get cold in a warm house. So here are my tips for boiler breakdowns:
Heated slippers. They are the only thing that can bring my cold feet back from being solid blocks of ice. 🤣
Fleecy throw on my lap when I'm sat still. Better than a normal blanket or throw, I have one that's fleece one side and velvety the other. Even better- a heated one.
Thick socks with rubbery soles. For times when the heated slippers aren't on.
Thick pyjamas, with bedsocks and even a scarf if really cold. The scarf cam double up amd be wrapped round your head if your ears or nose get cold in the night.
Layers - I've gone back to the old system of "thermal underwear".
For washing - boil the kettle a few times and transport to the bathroom.
Also - heat one room with an electric heater, at least part of the day, so you can get some respite.
Finally - don't let it drop below 13 degrees routinely, or it will cause damage to your personal possessions.
