I pay my gas and electricity by direct debit, and the gas bill has just gone up to £86 per month.
That seems nuts. I have a new build. We have underfloor heating with a thermostat that is accurate. During the day the temperature was usually at 18 degrees, occasionally I "splashed out" to 19-20 for a few hours. Overnight I ran it at 16 degrees, but brought it up to 18 for a month or two when the children kept waking up. I know it's been a long cold winter, but really? Am I being unrealistic?
I am aware that people run their thermostats lower, and will do if that's the only option, but speaking to peers at the time my house was cooler than many others.
