Tree Preservation Orders (TPO's) and development work

Tree Preservation Orders (TPO’s) enable the council to protect important trees. Trees with preservation orders or within conservation areas are protected under a range of legislation that makes it an offence to cut down, top, lop, uproot, damage or destroy those trees without first gaining permission from the council.

TPOs can be placed on any tree that has amenity value. Trees that are exempt from TPOs are those that are dead, dying, diseased or dangerous and fruit trees grown for the commercial production of fruit. 

Trees that grow in council owned property or on public open spaces are also protected as they are deemed as council property. Anyone wilfully damaging these can be prosecuted.
If you are doing work close to trees you should make sure that trees surrounding any development sites are protected by fencing. You can be subject to a fine should any trees be damaged during the development process. Further information is available in our tree care protection and development sites leaflet Tree Care Protection Advice and Development Sites (155KB).

If you have any queries or would like advice about tree care or protected trees, take a look at our frequently asked questions.

The maximum penalty for carrying out works to TPO trees without consent is £20,000.
