Tree work is a dangerous and highly skilled operation. Choosing an arborist (tree surgeon) is something that must be done with great care. Picking the wrong arborist could lead to:
Tree work operations (arboriculture) need a high degree of technical knowledge, supported by training and experience. For these reasons tree work should only be undertaken by well trained, competent arborists who hold adequate insurance.
Anyone can call themselves a tree surgeon and place an advert in Yellow Pages and offer a service. An advert alone does not guarantee quality of work or that it will be carried out safely.
Skilled arborists will have certificates which show that they have been trained and assessed. They will often have other academic qualifications in arboriculture and will use safety equipment to protect you, your property and themselves.
Reputable tree care companies will be pleased to give you copies of their insurance, qualifications and professional memberships and will work to nationally recognised standards.
