Welcome to MJCA

We have been providing reliable independent technical advice in a changing environment for over 30 years.


Since the early 1980s, MJCA has provided independent advice on environmental issues to the public and private sectors. Over this period, environmental management has changed significantly as our understanding of the environment steadily develops, standards tighten and new legislation is introduced. To keep ahead of this scientific, technological and legislative change we review continually and develop our services, to ensure that our clients receive advice which satisfies both best practice and current and future demands. Our proven environmental and operational experience, high technical standards and commercial awareness enable us to provide practical, cost effective advice and solutions.
