We are lucky enough to look after some of the most valued and historic trees in Oxfordshire, Buckinghamshire, Berkshire and Surrey. Excellent customer service is at the heart of what we do - here’s what a few of our valued customers say:

The CTS team members completed the job to their usual high standard: all in all, a very tidy and efficient and excellent job carried out with the usual pleasant and friendly team spirit. I shall contact you again at the end of this year, if I may, to book the next repeat appointment for the annual work to be done.

Complete Tree Services have looked after the trees at Granville Court for more than 20 Years. They know our trees well and care for them with great expertise. When we, sadly, have had to lose diseased trees, they have managed the operation expertly, with minimum fuss. They have also advised wisely on the planting of new trees.
