Tree surgery

It is important to exercise caution when deciding which arboricultural contractor to employ. Tree surgery requires knowledge, skill and experience. Inadequately qualified contractors may cause not only irreparable damage to your trees but also damage to your property.



Most people are unaware that there is a British Standard for Tree Work. ‘BS 3998:2010 Tree Work-Recommendations’ provides guidance on the main tree work operations. The standard is in place to ensure not only that work carried out on trees has the minimum impact on their health and structural condition, but also that the objectives based on the requirements of those requesting the works are achieved. For example, crown reduction can be undertaken to maintain the height and spread of a tree. If carried out incorrectly, with branches not cut back to suitable points of growth or too much of the crown removed, the subsequent re-growth may be more profuse, faster growing and with larger leaves than before. As a consequence, the original objective is not fulfilled whilst potentially costing the tree owner a large sum of money in the process.


We offer, where required, a range of tree surgery and tree care services, undertaken in accordance with BS 3998:2010, to ensure that our clients receive the highest possible standards of tree work.
