A guide to living in a conservation area

Trees within conservation areas

If you want to cut down, prune, top or lop a tree in a conservation area which is not covered by a Tree Preservation Order (TPO) you will need to give six weeks notice in writing, prior to any works starting.

The notification should include a description of the tree and any works to be carried out. This applies to surgery works or felling of any tree with a trunk over 75mm in diameter measured 1.5 metres above ground level.

We can then consider the contribution the tree makes to the character of the area, and if necessary issue a TPO to protect it.

There are some exemptions but we would strongly recommend that you contact our Arboricultural (Tree) Officer, who can come and have a look.

You can contact him on tel: 0203 567 6900. Please note it is your responsibility to provide proof of the exemptions, in the case of challenge.


  • if the tree has a stem diameter of less than 75mm (measured at 1.5 metres from ground level)
  • if the works being carried out are to help promote the growth of other trees, and the trees have a stem diameters of less than 100mm (at 1.5 metres)
  • if the tree is dead, dying or dangerous
