Leading experts in environmental compliance

Thomson was first established in 2004, known as Thomson Ecology. Founders Nancy Thomson (CEO) and John Mundy, were quickly followed by Richard Arnold as Technical Director. The three shared a vision to provide excellence and innovation in all aspects of ecology and biodiversity.

Today, operating as Thomson Environmental Consultants, we have a team of over 150 specialists on hand, with a wealth of knowledge and experience to share with our clients.

In-house at Thomson, we have expertise in terrestrial ecology, marine services, freshwater ecology and management, marine laboratory services (invertebrates, fish and sediment analyses), habitat creation and management, geospatial data management and mapping, arboriculture consultancy and contracting, and landscape architecture.

To support our work, we have a varied range of accreditations and industry memberships that demonstrate our commitment to standards and quality across our work.

Our partnership with Wessex Archaeology

All new construction projects must pass specific ecological and archaeological requirements before they receive planning permission. Our alliance with Wessex Archaeology places us in a strong competitive position, as together we offer our clients a complete service in the fields of ecology, environmental consultancy and archaeology.

The partnership offers developers a more efficient and streamlined method for commissioning these specialist services, allowing access to the best advice available as part of one contract without the need to go to multiple firms.
