I visited a friend today to take cakes and to coo and ahh at her new lovely house. We usually meet in town, I think I've only visited her in her old place once or twice in summer.
It was noticeably chilly freeeezing as we sat in her new living room; I kept my coat on and held my cuppa tightly. I mentioned, breezily, it was getting much colder now and the nights were drawing in, etc.
She laughed and said 'Maybe, but I never put the central heating on until 1st November. And it goes off again 1st May.'
I'm more of a try-a-jumper-first but if it's still cold then-pop-the-heating-on household, but is this self regulation a great idea?
