Our Services

“I have worked with Derek on probably more than one hundred different projects over
the years and have always been impressed by the depth of experience, thoroughness and determination that he brings to bear in working for the desired result. If negotiation fails and it comes to an appeal, it is those same qualities, together with fairness and professionalism in the way he presents his evidence and deals with cross-examination, that I believe make him such an impressive expert witness.”

- Eian Caws, Barrister

“I have used Derek Horne & Associates as my planning consultants for over the last twenty years and I have found them to be high achievers in all my dealings and problems with the various planning authorities.

The facts are that the Company lead by Derek Horne has always obtained the planning permissions that I have required. In addition he has represented a number of appeals for us all of which he won. I would be comfortable in recommending Derek Horne & Associates to anyone in liaising with the Planning Authorities with the objective of a positive result.”
