Best Draught Excluders for Front Doors UK 2026
Updated June 2026
Your front door has more draughts than any other door in your house. It has a letterbox (a direct hole to outside), a gap underneath, gaps around the frame, and sometimes a keyhole. The Energy Saving Trust estimates that draught-proofing your front door saves £25–£35 per year on heating. Total cost to seal everything: under £50. Here is exactly what you need.

1. The candle test. Light a candle and slowly move it around the door frame, letterbox and underneath. If the flame flickers or bends, you have a draught at that point.
2. The hand test. On a cold, windy day, run the back of your hand around the frame. Cold spots = draughts. Quick, free and surprisingly accurate.
3. A thermal leak detector. The most accurate method — points a temperature sensor at any surface and tells you exactly how cold it is. The BLACK+DECKER TLD100 Thermal Leak Detector (£25–£35) is the UK favourite.
