We, and our houses, are all different. I used to never turn my thermostat above 15 but now I’m old it’s creeping up. My house is very old, no insulation except the loft, and draughty.
Before even thinking about heating I checked that I shall actually get the winter fuel allowance this year. I need it but it should not be paid to those who don’t.
What are you avoiding doing in this heat?
