According to experts at the Energy Saving Trust, the idea it's cheaper to leave the heating on low all day is a myth. They're clear that having the heating on only when you need it is, in the long run, the best way to save energy, and therefore money

Quite correct - the boiler operates more efficiently when the temperature change is small but at the end of the day you’re still running it more; in a poorly insulated house you’re running it a *lot* more because a chunk of the heat you generate is going straight through the walls. This is why home efficiency measures like insulation and draught proofing are so important.
