Common projects: Flue

Planning Permission

Fitting an external flue for a boiler/burner will normally be permitted development if the conditions outlined below are met:

  • Flues on the rear or side elevation of the building are allowed to a maximum of one metre above the highest part of the roof.
  • If the building is listed or in a designated area even if you enjoy permitted development rights it is advisable to check with your local planning authority before a flue is fitted. Consent is also likely to be needed for internal alterations.
  • In a conservation area or in a World Heritage site the flue should not be fitted on the principal or side elevation if it would be visible from a highway.


Building Regulations

If you wish to install a flue, building regulations apply. You should take into account factors such as ventilation and general safety. Installation should be carried out by a suitably qualified installer
