How to become a supporter

ATO relies on subscriptions from its members and income from supporters to operate and represent its members.

Becoming a ATO supporter provides you with an opportunity to have your company logo on the ATO website, with a 500-word description of your company and its products, at an annual cost of £300 per annum. This opportunity will provide exposure for your company, and your support will assist ATO to represent tree officers when dealing with matters concerning central government and regional local authorities.

One of the benefits of becoming a ATO supporter is direct access to sponsorship opportunities as and when they arise. Being a ATO sponsor will provide your company with additional targeted exposure.

Tree Life


Tree Life has been dedicated to improving people’s understanding of trees and their management since 1997. From humble beginnings, we have grown into the premier independent UK training provider and are proud to count numerous tree officers amongst our previous and current students.

Not only do we teach up to degree level, we also ‘practice what we preach’, with our founder Dave Dowson being an AA Registered Consultant, and fully qualified expert witness. The current Level 4 and Level 6 Diplomas in Arboriculture exist as a direct result of Dave’s tireless endeavours on behalf of the profession. Many people will now be familiar with the Professional Tree Inspection course, another of Dave’s achievements in his quest to establish consistent and recognised best practice across the industry.

Our mission has always been to improve the treatment of trees by improving education for all. We rely on the likes of tree officers up and down the country to put that theory into practice. So, we take our corporate hat off to ATO members and applaud the work they do, and the achievements they are able to make under sometimes very difficult and challenging circumstances.

As well as teaching the Level 2, 4 and 6 Diplomas both in person and online, Tree Life offers Professional Tree Inspection training and other short courses – for details and locations, please visit our website at or feel free to give the office a call on 01162606939
