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:
- 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.
- In a designated area the flue should not be fitted on the principal or side elevation that fronts a highway.
Please note: the permitted development allowances described here apply to houses not flats, maisonettes or other buildings. View guidance on flats and maisonettes here.
Permitted Development for householders – Technical Guidance
You are strongly advised to read a technical guidance document produced by the Government to help understand how permitted development rules might apply to your circumstances.
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
