Burning cleaner

Use cleaner fuels on your stove and fires, such as smokeless, authorised fuels or dry, well-seasoned ‘ready to burn’ wood with low moisture content. Please consider the amount and type of fuel or wood you buy ahead of winter months.

Ready to Burn regulations

Since 1st May 2021 new laws apply to the sale of coal, wood and manufactured solid fuels. The government are phasing out two of the most polluting fuels, traditional house coal and wet wood, to help improve air quality.  The ‘Ready to Burn’ logo has been introduced to help customers choose less polluting alternatives, dry wood and manufactured solid fuels. Use ‘Ready to Burn’ labelled wood and solid fuels to help meet the new rules. Read more here.

Types of fuel

Particulate matter pollution from different solid fuels:

More polluting 
Wet/green wood
Low sulphur coal
Dry wood
Less polluting 

Burning household waste in a wood burner or on bonfire is illegal. Garden waste should be composted or collected by your local council, as most garden waste will not be dry and will burn with a lot of smoke. Be considerate to your neighbours and community when lighting bonfires, outdoor burners and BBQs and take care not to cause a smoke nuisance. 

Do not burn wood treated with varnish, paint, creosote, glue etc. such as garden fences, laminates, skirting boards, pallets, furniture; don’t burn oil/synthetic rubber or plastics and avoid burning firelighters. Burning treated wood and household waste will create harmful fumes and toxic pollutants, such as arsenic. 

If you live in a Smoke Control Area you can only burn DEFRA authorised smokeless fuels instead on DEFRA exempted appliances, or face a fine of up to £1,000. 

Where you buy fuel

Buy wood from a trusted local, sustainable and managed source, to reduce the environmental impact. If you want to burn the wood straightaway without seasoning, look for the ‘Ready to Burn’ logo, which indicates good quality dry wood. Find Woodsure Ready to Burn suppliers. Wood should not be too large, as using large logs can produce a lower burning temperature, waste fuel and more air pollution. Logs that are 13cm or 5 inches wide are the ideal size. 


Wet, green, freshly cut wood must be seasoned before burning. Depending on size and moisture content wood should be seasoned for a minimum of 6-12 months, and ideally 2 years. Burning unseasoned wood increases air pollution and can damage your wood burner and chimney. 

Moisture content

Dry wood should have a moisture content of 20% or less; this can be tested with a moisture meter. If you want to test the moisture content of your wood, the most accurate reading comes from splitting the log and testing the split surface. Wet wood creates smoke and particulate air pollution, which has health impacts, can damage your wood burner and chimney and heats your home less efficiently. 


Wood should be stored off the ground, with air flow and rain cover. Cutting and splitting logs is easier when it is green and this increases the surface area so it will dry faster. It’s best to stack wood to allow air flow rather than heaping into a pile, and log stores should have open sides and a roof to protect from wet weather. 

Is burning wood low carbon?

Wood burning has been considered a low carbon heating option but it takes a long time for trees to re-grow and re-capture the carbon released by burning. Wood for burning may have been transported long distances and energy used to dry it e.g. kiln drying, which adds to its carbon footprint. Read more.
