Professional and Experienced Environmental Consultants and Ecologists

Since incorporation in 2016, our team has grown and diversified, enabling Carcinus to provide a wide range of environmental services. We pride ourselves on the high quality support we offer our clients and ensure our team and associates always comprise highly qualified and recognised individuals with ‘real world’ commercial experience of operating in the aquatic environment sector.

Our team have managed and delivered environmental consultancy and ecological services for major infrastructure projects throughout the UK and overseas, ranging from inland waters and coastal development to offshore projects for the oil and gas and renewable energy sectors. All staff have a clear understanding of project consenting requirements within UK freshwater, coastal and marine environments.

Our environmental and ecological consultants regularly engage with stakeholders and regulators and have established relationships with regulatory and statutory nature conservation bodies and stakeholders working in or near aquatic environments. Our staff have contributed to Regulatory Advisory Groups (RAG) promoting survey and data interpretation methodologies and hold high profile fellowships and memberships of professional institutions and organisations relevant to the fields of biology, zoology, fisheries and archaeology.
