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.
