Clean Air Act approval

The Clean Air Act 1993, introduced a wide range of new regulations such as those which control smoke emissions and the height of chimneys and those relating to the content and composition of motor fuels. Under certain conditions we must approve chimney height.

Installation of Furnaces

This section does not apply to the installation of domestic furnaces – defined as those with a maximum heating capacity of less than 16.12 kilowatts. Furnace means any enclosed or partly enclosed space in which solid, liquid or gaseous matter is burned, or in which heat is produced.

Approval of Furnace Chimney Heights

Under Section 14 of the Act, unless the height of the chimney has been approved by the local authority it is an offence to cause or knowingly permit a furnace to be used to:

  • Burn pulverised fuel;
  • Burn at a rate of 45.4 kg or more an hour any other solid matter;
  • Burn at a rate equivalent to 366.4 kilowatts or more, any liquid or gaseous matter.

An application for chimney height approval must contain adequate information to enable the minimum permissible chimney height to be calculated.
