Authorised fuels and exempt appliances
Authorised fuels are fuels which are authorised under the Clean Air Act 1993. These include inherently smokeless fuels such as gas, electricity and anthracite together with specified brands of manufactured solid smokeless fuels. These fuels have passed tests to confirm that they are capable of burning in an open fireplace without producing smoke. View a list of authorised fuels.
Certain appliances (ovens, wood burners and stoves) have been exempted under the Clean Air Act 1993. These have passed tests to confirm that they are capable of burning an unauthorised or inherently smoky fuel without emitting smoke. View a list of exempt appliances.
The Department for Food, Environment and Rural Affairs (Defra) have produced a practical guide to explaining the law around open fires and wood-burning stoves in smoke control zones.
