Overview

• Lewis advises closing curtains at sunset to trap heat, which for the UK on October 16 falls just after 6 p.m., to delay switching on central heating.
• The guidance was filmed in November 2022, and MoneySavingExpert confirms the tips remain effective.
• Households are encouraged to use thermal or fleece-lined curtains or to add cheap fleece linings, ensuring any fleece used is fire-resistant.
• The curtain tactic sits alongside other low-cost steps such as radiator reflector panels and tackling draughts, consistent with his “heat the human, not the home” approach.
• Retail options are widely available at mainstream chains, with examples cited from The Range and Dunelm, as well as Amazon, Argos, B&Q and Tesco.
