Biomass or combined heat and power (CHP) flues
Flues on dwellings or flats will normally be regarded as "permitted development" and would only need planning permission if:
- The flue would exceed the highest part of the roof by one metre or more
- The flue is on an elevation or roof slope visible from a highway if located within a conservation area or World Heritage Site
- Permitted development rights have been withdrawn
If the property is a listed building you might need to have listed building consent.
