Trees in conservation areas
If a tree is in a conservation area but is not covered by a Tree Preservation Order (TPO), you’ll need to give written notice (a Section 211 notice) to the Local Planning Authority at least 6 weeks before the work starts.
You can get help submitting a Section 211 notice on the Planning Portal or get advice from a tree surgeon.
You do not need to give notice on a tree in a conservation area if it’s less than 7.5 centimetres in diameter, when measured from 1.5 metres above the ground.
