Dangerous trees

The maintenance of a tree in a safe condition is the responsibility of the tree owner.  If you believe a tree in your garden is dangerous, you should contact a reputable tree surgeon to inspect it as soon as possible, you can search for qualified contractors on the Arboricultural Association’s website at:  https://www.trees.org.uk/ARB-Approved-Contractor-Directory
