Expert witness services


Appearing as an expert witness in a court case or a planning inquiry is the pinnacle of professional practice.

Arboriculture is an unusual mix of the practical and the academic, where hands-on experience makes all the difference to the calibre of advice that a consultant can offer. What makes Barrell Tree Consultancy such a formidable group of tree experts is their extensive practical background of climbing, pruning and managing trees, informed by a stunning array of professional qualifications. We are the only tree consultancy in the UK with four Chartered Foresters and three AA Registered Consultants in our ranks, which makes us a wise choice for your expert witness requirements.

Jeremy was an AA Approved Contractor for 10 years before becoming a Registered Consultant, a perfect background for both tree hazard and planning cases. In contrast, Mark Wadey, Dave Cashman and Andy Sherlock acquired their skills as council tree officers, which gives them a distinct edge in planning appeals.
