Many planning permissions for new houses or extensions contain conditions which protect trees and hedges. These may include both the existing vegetation and any new landscaping required by the planning permission.
The condition may last for a period of up to 5 years but sometimes for longer. If it is proposed to retain trees for the long term then a Tree Preservation Order (TPO) is often used rather than a planning condition. Although the wording may vary, conditions generally require that you obtain the prior approval in writing for work to trees or hedges.
Applying to carry out works to a tree protected by planning conditions
If the condition prevents works being carried out, then you will need to apply for a Variation of Condition by making a planning application http://eastdevon.gov.uk/planning/planning-permission/apply-for-planning-permission/remove-or-vary-a-condition/
If the condition makes provision for approved works to be carried out, then you need to apply for a discharge of condition http://eastdevon.gov.uk/planning/planning-permission/apply-for-planning-permission/discharge-of-conditions-application/
