As the weather gets colder, more and more people are reaching the central heating to warm themselves up.
But what is the most cost-effective way to have the heating on?
Martin Lewis spoke about this whilst speaking with Holly Willoughby and Phillip Schofield during an instalment of This Morning, he addressed whether homeowners and tenants should look to switch off the central heating or leave it on all day.
The idea of keeping the heating on all day has been called a myth by the Energy Saving Trust - and Martin also expressed similar advice.
He said “They say it’s better to only put the heating on when you need it.
"You pay to pump energy in as and when is needed, and to keep pumping it in constantly isn’t efficient.”
“There are some engineers though who argue that keeping the heating on low with all the radiators on and the boiler down can work as it reduces condensation,” he said.
“Which when the heating is turned off collects within the walls, and can help conduct heat outside the home – meaning you lose heat more quickly and so will use more energy as a result.
“So if your house is prone to that you may want to think about it.”
