Now the weather outside is freezing cold, many Brits have decided to put the heating on full blast in their homes.
And with many of us still working from home, you may have noticed your heating bills more expensive than ever. Boo.
That said, many people have been asking whether they should keep their heating on low all day, or if it's best to put it on every now and again to keep bills as low as possible.
It's an age-old debate. Some experts argue that it depends on how well your home is insulated, as this will determine how much energy you need to heat it up.

Sarah Broomfield, energy expert at Uswitch.com, explained that if your home experiences greater heat loss, you'll spend more money maintaining the inside temperate.
Therefore, it is best to only turn the heating on when you need it, if you go by this logic.
“For those living in properties that aren't as well insulated, the cost of leaving your heating on all the time will be especially expensive,“ she explained.
“Typically the most energy-efficient approach to heating your home is to programme your heating system so that it comes on at times when you need it most.
“And with many of the more modern room thermostats you also have the ability to set different temperatures at different times - and even set up a separate timer for weekends.“
The Energy Saving Trust has also previously said it's better to heat your home only when you need it, if you're losing energy all day.
On its website, Energy Saving Trust says: "Heating controls help you keep your home comfortably warm, without over-heating and wasting energy.
"By installing and using your heating controls effectively, you could save money on your heating bills and lower your carbon emissions."
However, some specialists who've previously spoken to MoneySavingExpert have argued the exact opposite - and say you should keep the heating on all the time.
The specialists the consumer website spoke to said condensation collects within the walls whenever you switch the heating off.
This can then conduct heat outside the home, which could mean you lose heat more quickly in the long-run.
Ultimately, it depends on the type of building you live in and how good it is at keeping heat inside.
