Chimney heights

Chimney heights have to be approved by the local authority, under the Clean Air Act 1993.

Unless a chimney height has been approved, 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 per hour any other solid matter
  • burn at a rate equivalent to 366.4 kw or more any liquid or gaseous matter

Applying for chimney height approval

If you want to get your chimney height approved, please fill in an application form and send it to us. You must give us enough information about your chimney to enable us to carry out the necessary calculations.
