what we're about

Diversity provides a bespoke environmental consultancy service enabling clients to fulfil their project aspirations whilst protecting and improving the natural environment.  


Being a small independent company we're not driven by a need to generate work for a large number of staff but are able to focus on projects that have the objective of being socially and environmentally sustainable.  This also means we give clients the personal attention they need to see their project through to a successful conclusion.   

focusing on what's important


Legislation and planning policy relating to the natural environment can be confusing.  But we can help...


With over 20 years experience as an environmental consultancy and fielding just a small team of dedicated specialists, we provide you with the targeted environmental services you need based on up-to-date published guidance and what is most relevant to the location and your project proposal. Our focus is on serving the client and nature.

What our clients say

  • Sally Gilbert, United Communities

    "I have worked with Rob Craine for more than 10 years.  He is an absolute delight to work with, he loves coming up with solutions which ensure compliance with statutory requirements but may also involve working with young people, sharing his knowledge and enthusiasm in all areas of ecology and nature.  Rob is able to communicate with a broad range of people and is trusted by the professionals in the planning departments, a great asset when projects have challenges that need a joined up approach.  He communicates equally well in other less professional settings.  I work in affordable housing and Rob has shown commitment to working positively in communities, giving up his own time showing residents how to encourage wildlife into  gardens and working with local schools.  I cannot recommend Rob more, he understands the challenges of projects and development and is able to balance often conflicting priorities in a way that works for wildlife and nature but still enables development."

  • Derrick Whittaker, Architect

    "In my role as Architect I am frequently appointed as agent undertaking planning applications, many of which require specialist reports. Diversity is one of a very short lift of consultancies I am comfortable in recommending to clients as I find their reporting and recommendations to be very clear, concise and practical.  This clarity is coupled with their ability to deal with difficult projects and sometimes demanding local authorities."

  • Robert Cole, Robert Cole Civil Engineering Ltd

    "We turned to Rob Craine of Diversity to guide us through the process of converting two barns in the Forest of Dean with sensitive ecology.  Rob's professional advice was invaluable with his helpful and pragmatic approach.  He understood the challenge of a commercial development and we were able to work together to complete the project leaving the ecology and habitat enhanced.  We have no hesitation in recommending Diversity and look forward to working with their team again."

  • Daryn Willington, Independent builder

    "Rob's depth and breadth of knowledge was immediately apparent as he read the site, correctly anticipating species finds and exposing corroborating signs hitherto thought unrelated.  His timeley advice and quick turnaround for the report greatly helped, creating a benchmark and goals for the client as well as engendering confidence witht the relevant authorities, creating a route for the project."

  • Chris Roe, Hedge Roe Properties Ltd

    "Rob Craine and his team undertook an ecology survey across the land on our site.  Rob was a pleasure to work with, he explained exactly what needed to be done and helped us understand the outcome and impact on our development project.  He provided a full report that was submitted to the Council and also helped us deal with subsequent requests and clarifications from the Council."

  • Griff Hughes, Householder

    "Rob provided us with his expertise to support a residential planning application.  All went through perfectly and was turned around in days to the planner's satisfaction."




We operate an Environmental Management System...  Apart from avoiding printing (or only using only recycled paper), our transport is with electric vehicle (in some instances bicycle), our office is heated with biomass, and our computers are powered by wind and solar energy.
