Chimney fire safety

Using an open fire, wood-burning stove or multi-fuel appliance can be a safe and effective way to heat your home. However, chimneys and flues need regular care to reduce the risk of chimney fires and carbon monoxide exposure.

• Have your chimney swept regularly by a qualified professional.
• Use the correct fuel for your appliance and avoid wet wood, treated wood, rubbish or household waste.
• Never use petrol or paraffin to start or revive a fire.
• Use a fireguard and keep fuel, furniture, clothing and soft furnishings a safe distance from the fire or stove.
• Make sure the fire is fully out before going to bed or leaving the house.
• Fit and test smoke alarms and an audible carbon monoxide alarm.

Sweeping and maintenance

How often you should sweep a chimney depends on the fuel you burn. HETAS recommends at least twice a year when burning wood or bituminous house coal, and at least once a year when burning smokeless fuels.

Fuel choice and safer burning habits

Use Ready to Burn fuel or dry seasoned wood with a moisture content of 20% or less where appropriate. Do not burn treated waste wood, old furniture, pallets, cardboard, plastics or household rubbish.

Warning signs and urgent attention

Get a professional inspection if you notice smoke re-entering the room, a persistent, bad smell, soot falling back, visible tar, birds nesting in the chimney or the fire not burning as well as usual.
