I haven't got the heating on yet, and don't feel the need.
I am ready for winter though. I have bought some HeatGen tops and thermal undies, and have sheepskin slippers, fleece-lined slipper socks and chenille bedsocks. I have lots of warm jumpers (I'm a knitter), too.
I also have an electric blanket (but again, haven't felt the need yet) and a heated throw, which I've used once or twice in the evening. It's only Autumn though.
