Flue, chimney or soil and vent pipe

Planning Permission

Fitting, altering or replacing an external flue, chimney, or soil and vent pipe is normally considered to be permitted development, not requiring planning consent, if the conditions outlined below are met:

  • You can install, alter or replace a chimney on your house without the need to apply for planning permission if it does not project by more than 1m from the highest part of the roof.
  • If you live in a conservation area, a national park, an area of outstanding natural beauty or a World Heritage Site, the installation, alteration, replacement or removal of a chimney will require planning permission.
  • 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.

Please note: the permitted development allowances described here apply to houses not flats, maisonettes or other buildings. View guidance on flats and maisonettes here.
