Tree Preservation Orders (TPO), conservation areas and planning issues

Planning permission and protected trees

Trees are protected in one of two ways, either by inclusion in a Tree Preservation Order (TPO) or if the trees are within a conservation area.

You will need our consent before you do any work to a TPO tree. You will need to give us written notice six weeks ahead of work on trees in conservation areas.

It is a criminal offence to carry out work to protected tree(s) without the necessary consent / notification.

TPO treework application form - this form can also be used to give Notice of Intent for work to tree(s) in a conservation Area:

TPO treework guidance notes

To check whether trees are protected email us with details of the location and type of trees. We are unable to check a tree’s status by telephone.


Data on Tree Preservation Orders (TPO) can be found on Barnet Open Data More details regarding protected tree law can be found on the GOV.UK.
