The correct height ensures that these pollutants are properly dispersed and do not affect local residents.

If your chimney height has not been approved, it is an offence to:

  • burn pulverised fuel
  • burn at a rate of 45.4 kg or more an hour any other solid matter or
  • burn at a rate equivalent to 366.4 kW or more any liquid or gaseous matter
