Overview
- A viral tip to place kitchen foil behind radiators is being challenged by safety and energy specialists who say the gains are minimal.
- Energy expert Scott Byrom cautions that ordinary foil can degrade or oxidise next to heat, increasing the risk of smouldering or fire.
- Firefighter Andrew Topping, with 26 years' experience, warns the hack can become hazardous over time as the foil deteriorates with heat exposure.
- Advisers recommend purpose-made radiator reflector panels or prioritising draught-proofing as safer, more effective ways to improve heating efficiency.
- The Energy Saving Trust estimates reflector products can save roughly £20–£25 a year and such panels are widely sold at retailers including ScrewFix, B&Q and Amazon.
