New Aldi £4 'warm house' kit reduces draughts like £10 Dunelm version out Sunday UK homeowners can keep their properties warmer during autumn and winter with the £3.99 kit As autumn temperatures drop, households across the country are actively seeking affordable ways to keep their homes warm without facing skyrocketing central heating bills. High energy costs remain a primary concern for many families, prompting a surge in demand for practical, low-cost draught-proofing solutions that do not require professional installation. Among the most affordable options on the market this season is the Aldi Easy Home Window Insulation Kit. Priced at just £3.99, this budget-friendly product is due for UK-wide release in stores this Sunday, October 18, as part of the supermarket's upcoming Special Buy refresh. Aldi says: "Keep your home warmer and more energy efficient with this easy-to-install window insulation kit. Designed to help reduce draughts and heat loss, it's a simple solution for a cosier living space." The kit is designed to significantly reduce heat loss through older, drafty, or single-glazed windows. The kit functions by creating a temporary, airtight thermal barrier over existing window panes. It contains a clear plastic shrink film and a roll of double-sided tape. Users attach the tape to the window frame, apply the film, and then use a standard household hairdryer to shrink the material until it is completely taut and wrinkle-free. This simple process traps a crucial layer of still air between the cold glass and the living space. It effectively mimics the effects of secondary glazing. Energy efficiency experts say that uninsulated windows account for a significant share of heat loss in typical residential properties. By sealing up draughts, kits like the one at Aldi help stop cold air from entering homes and prevent expensive indoor heat from escaping. Because the film is designed to keep indoor rooms noticeably warmer for longer periods, households can comfortably delay turning on their central heating or safely lower their thermostat settings. For less than five pounds, a single pack covers up to five standard windows, making it an incredibly high-value investment that easily pays for itself within just a few days of use. Aldi's £3.99 Easy Home Window Insulation Kit is similar to the Stormguard Secondary Glazing Window Film set available at Dunelm. The "easy to fit" kit is described as an economical alternative to double glazing as it "creates a secondary glazing effect across any window". Dunelm also says that it "helps save energy and money on your heating bills". However, it costs £10 and "covers four windows". Aldi's £3.99 version covers five. According to experts at Homes and Gardens, window insulation kits can reduce heat loss through your windows by up to 35% and cut your overall winter heating bills by 10% to 20%. They provide a highly noticeable difference if you have older, drafty, or single-pane windows.
