There are smoke control areas in parts of Flintshire, Newport, Swansea and Wrexham. To check if you live in a smoke control area, visit Wales Smoke Control Areas Map on DataMapWales.

In a smoke control area, it is an offence to:

  • emit smoke from a chimney of a building - this includes outdoor buildings that have a chimney, such as summerhouses
  • buy or sell unauthorised fuel for use within a smoke control area, unless it's used in an 'exempt' appliance (appliances which are approved for use in smoke control areas)

The list of authorised fuels and exempt appliances for smoke control areas in Wales can be found on the DEFRAs Clean Air Act Data Entry System.
