The heating is on, the evenings are dark, and winter scented candles are back on the coffee table. But many UK homes are draughty. Air slips in round sash windows, under doors and through the letterbox. That moving air is the quiet reason a candle smokes, flickers or burns down one side. Where you put the candle matters as much as what it smells like.
Where Winter Scented Candles Burn Best
A steady flame needs still air. Humberside Fire and Rescue Service advises keeping burning candles away from draughts, vents, ceiling fans and air currents. It says this helps stop fast, uneven burning, flare-ups and soot.
Draughts carry a second risk. They can blow a light curtain or a loose sheet of paper into the flame. So a windowsill is a poor spot, however pretty it looks from the street.
Look for a flat, heat-proof surface in the middle of the room. Keep it away from the door you open most.
How do I know if my candle is in a draught?
Watch the flame for a minute. If it leans, dances or sends up thin wisps of smoke, air is moving across it. Move the candle a metre or so and watch again.
The Draughty Spots to Avoid at Home
These are the usual draughty spots in a British house or flat:
- Windowsills, especially old sash or single glazing
- Hallways near the front door and letterbox
- Shelves beside an extractor fan or air vent
- Fireplaces with an open chimney above
The same service also says to keep burning candles at least three inches (about 8cm) apart. Close candles melt each other and make their own little draughts.
Tealights are the easiest to place well. They are small and low, and they sit flat on a saucer or a holder. The tealights in our 2026 Advent Calendar have a four-footed base, built for a steady, even flame.
What to Do When a Candle Keeps Smoking
Do not keep blowing on it or moving it while it is lit. The fire service advice is simple. Put the candle out if it smokes, flickers again and again, or the flame grows too tall. Let it cool. Trim the wick, then check for draughts before you light it again.
Most of the time, the fix is just a new spot.
Quick answers
Why does my candle burn down one side?
Usually a draught. Moving air pushes the flame to one side, so that side melts faster. Move the candle away from windows, doors and vents, and the wax should start to level out again.
Can I put a candle on a windowsill in winter?
It is best not to. Windowsills tend to be draughty, and curtains or blinds hang close by. A table in the middle of the room, away from anything that can catch fire, is safer.
