Martin Lewis Advocates Clingfilm Window Hack to Combat Soaring Heating Costs
Financial guru Martin Lewis has unveiled a remarkably simple and affordable home hack to help millions of Britons stay warm while drastically reducing their energy expenditure this winter. The surprising solution involves using ordinary kitchen clingfilm, a household staple costing as little as £1.50, to create an effective thermal barrier on windows.
The Science Behind the Clingfilm Solution
According to guidance from Martin Lewis' MoneySavingExpert platform and the Centre for Sustainable Energy, applying this "secondary glazing" technique can significantly improve home insulation. The thin transparent plastic film, which resembles standard clingfilm and is easy to install, forms a crucial air pocket when stretched over window frames.
This insulating layer prevents substantial heat loss as temperatures plummet, with the material available for approximately 78p per square centimetre. While specialist glazing products offer superior performance due to their specific design, MoneySavingExpert recommends clingfilm as a readily accessible and budget-friendly alternative for immediate results.
Additional Energy-Saving Recommendations from MoneySavingExpert
The comprehensive guidance extends beyond window treatments to include several practical measures for household efficiency:
- Maintain boilers at consistent low temperatures throughout the day rather than frequently switching them on and off
- Unplug chargers from sockets when not actively charging devices
- Switch off lights upon leaving rooms and ensure internal doors remain closed to contain warmth
- Keep heating systems operational during extended absences to prevent frozen pipes, which can lead to repair bills exceeding hundreds of pounds
- Recognise that solar panels continue generating electricity during winter months
Debunking Common Energy Efficiency Myths
The MoneySavingExpert advice also addresses several widespread misconceptions about heating efficiency. Contrary to popular belief, painting radiators black does not enhance their performance, and installing smart meters does not automatically guarantee savings without conscious usage adjustments.
Martin Lewis further cautions against potentially dangerous cost-cutting measures, specifically warning that heating water in microwaves instead of kettles, while marginally cheaper, poses serious safety risks. Microwaves can superheat water to explosive temperatures, creating hazards comparable to hot oil and risking severe burns, making traditional kettles the safer choice even for extremely frugal households.
Historical Inspiration for Modern Energy Savings
This clingfilm recommendation follows heating experts at Plumbworld advocating a "Victorian fix" for contemporary energy challenges. Their method involves hanging heavy door curtains, historically called portières, across draughty internal doorways and behind front doors, complemented by basic draught excluders at floor level.
This fabric barrier effectively traps purchased warmth within frequently used rooms without requiring special tools or gadgets, making it renter-friendly and quickly installable. Research from Salford University Energy House demonstrates that heavy curtains can reduce window heat loss by approximately 33% on modern glazing, while Historic England studies show 39% reduction for traditional sash windows.
With energy price caps continuing to escalate alongside the broader cost of living crisis, these practical solutions offer tangible relief during particularly cold winter periods when heating demands and associated bills typically surge to astronomical levels.
