The money-saving expert confirmed that reflective foil can help keep homes warmer by reflecting heat back into the room rather than allowing it to escape through external walls.

Speaking on The Martin Lewis Money Show Live, Martin explained that the trick works best when used behind radiators fitted to external walls.

He said: "Fit reflective foil behind external walls, you can get specialist foil – only on external walls not interior walls."

Martin also shared other simple ways households can improve heating efficiency, including turning down radiators in unused rooms, bleeding radiators when necessary and keeping furniture away from heat sources.

While reflective foil will not guarantee a specific reduction in energy bills, it can be an inexpensive way to reduce heat loss and make better use of household heating.

With colder weather approaching, Martin's advice could help households stay warmer while making their energy go further.
