Not cold enough, though the flipping DC disagree.
I can't bear being hot. We argdue endlessly about the central heating. I get tetchy if it's more than about 10 degrees, though I grew up in a huge and draughty house where you just put another dog on your bed if you were cold.
My titchy kitchen is roasting as there is an Aga. I suggest my DC sit on it, if they are cold.
Otherwise. If everyone in your household is in agreement, I suggest closing the windows (several panes in my tiny 300 yr old house are broken, thank goodness, as it's natural ventilation - though the pesky DC block their broken panes up with bubble-wrap). Closing all the curtains apparently helps. Open fires also work, if you have one. My DC all have two goose-feather duvets (warmer than anything else, apparently), and blankets. I caved in and bought the youngest a fan heater, as she said that if I really loved her, I would not let her be so cold (has she never heard of cardigans?). The DC are in favour of turning up the thermostat, which causes some discussion, but it's a sure-fire way to a hot house.
My solution is to turn off the radiator in my bedroom and open the window (and keep my door shut), while turning the thermostat up everywhere else. That way, at least one room in the house is tolerable (to me), while everyone else roasts. Though I appreciate that you are asking a rather different question!
