Do I need planning approval
Chimneys and flues
You need to apply for planning permission if the chimney, flue or soil and vent pipe would exceed the highest part of the roof by one metre or more.
If you live in a conservation area
You will also need to apply for permission if the proposal would be installed on a wall or roof slope that fronts a highway and is either the principal or a side elevation of the house.
