Who we are

Johns Associates was set up as an environmental consultancy in 2007 and has grown organically from a team of two into a vibrant, multi-disciplinary organisation with a global perspective.  Our head office is located in Bradford on Avon, UK.

We’re a diverse and growing group of motivated, highly skilled professionals with a substantial depth of experience across different environmental and social disciplines. We invest heavily in our people through training and professional development. As a company we’ve attained a wide range of accreditations and won environmental awards for our work. This is supported through the use of cutting edge technology and a can-do attitude. Johns Associates and its team have a range of professional accreditations and memberships that demonstrate our accountability and the professionalism of our work.

We work pragmatically to find the most effective solution for you and your project and our approach is based on the understanding that capable, happy, well supported staff work well with you and deliver high quality work.

The whole company engages in activities that benefit our local environment and community. That extends our positive influence beyond our commercial work.

We won the ICE Environment and Sustainability Award in 2013, and more recently were delighted to be awarded the CIEEM 2018 Best Practice Award for Large Scale Mitigation and/or Enhancement in partnership with Drew Smith Ltd and Sovereign Housing Association Ltd. We were also finalists in 2017 for the Royal Town Planning Institute’s “Excellence in Planning for the Natural Environment” award, for which the same scheme was Highly Commended. We achieved the Investors in People Platinum standard in May 2020.
