Air quality

Woodburning stoves and open fires can contribute to air pollution if they are not used correctly. The smoke they produce contains tiny particles that can affect air quality and harm health. Some are so small that they can pass easily into our homes and workplaces.

The good news is that simple changes can make a big difference. Using a stove correctly can significantly reduce the amount of pollution it creates while helping your appliance work more efficiently.

Signs your stove may not be burning efficiently

You may be creating more smoke and pollution than necessary if you notice:

• blackened stove glass
• constant smoke coming from your chimney
• large amounts of unburned wood or charcoal left behind after the fire goes out
• excessive soot or tar in your chimney

Regular chimney sweeping can help identify problems and keep your stove working safely.

Tips for cleaner burning

To reduce pollution and get the best performance from your stove:

• use dry wood with a moisture content of 20% or less
• if buying logs, look for the Ready to Burn logo
• use plenty of kindling or suitable firelighters to establish the fire quickly
• keep air controls fully open when lighting the fire
• allow the fire to establish before adding larger logs
• follow the manufacturer's instructions for using air controls
• consider using a flue pipe thermometer to help maintain the correct operating temperature
• once the optimum temperature has been reached, partially close the air controls to reduce the burn rate.
• the fire should burn brightly, and the stove glass should remain clear.
• check your chimney regularly for smoke outside of lighting and refuelling periods. Visible smoke during normal operation indicates that the appliance is not burning efficiently or correctly.

Burning fuel efficiently can improve air quality, reduce fuel use and lower chimney maintenance costs.

Smoke control areas

If you live in a smoke control area, you must use approved fuels or approved appliances.
