ESU1 was founded to supply service and maintenance solutions for operators of existing ambient air quality monitoring equipment and has expanded to become a total environmental monitoring and compliance company, achieving ISO9001 accreditation in 2013 and full UKAS Management Systems by 2015.

ESU1’s various milestones include:
