The cost of a tree surgeon will depend largely on the overall size of the project, the amount of trees that need to be looked at, ease of access and the species of tree itself. Tree surgeons normally work in teams of two or three, to ensure the work can be carried out safely and efficiently. The price will normally be agreed before any work is carried out, but as a general rule of thumb, the average hourly rate could range from anywhere between £40-£100 per hour.
