Doing work to a tree
Work to a tree with a preservation order
You need to apply for permission to do work to a tree with a preservation order (TPO).
Your application will need a site plan that shows where the tree is on the property. If you are carrying out the work because the tree is diseased or damaged then you will also need to provide a tree survey, which can be supplied by an arboriculturalist.
Before you apply read the Planning Portal's guidance for tree work applications. This will help you describe the work you are doing, which will make it more likely that your application is accepted.
