Turn it down by 1°C
Room thermostats prevent your home from getting warmer than necessary. They turn the heating on until the room reaches the temperature you’ve set, and then off until the temperature drops. It should be set to the lowest comfortable temperature, which for most of us is between 18°C and 21°C. Energy experts at uSwitch estimates that if you turn down your thermostat by just one degree you could save £80 a year on your heating bill.
Room thermostats need a free flow of air to sense the temperature, so they should not be blocked by curtains or furniture, or placed near heat sources that could give them false readings. You don’t need to turn your thermostat up when it is colder outside; the house will heat up to the set temperature regardless. It may take a little longer on colder days, so you might want to set your heating to come on earlier in the winter.
