Why do so many men and women argue over the thermostat?

The temperatures have plummeted, and the annual battle for control of the thermostat is breaking out in Britain’s households!

On the face of it, thermostat control might seem like a trivial issue. But as any spouse will tell you, small issues can often turn out to have outsized effects – both on the marital relationship, and the family budget.

Indeed, according to one recent survey by manufacturer Honeywell, 30 percent of respondents who live with at least one person admit they can never agree with housemates about temperature. And 27 percent take matters into their own hands, by changing settings without others’ knowledge.

What are your views? How do you work out the optimum household temperature in your home?  Who controls the thermostat?
