About Us

Our History

ESU1 was founded to provide an emergency response and regular maintenance service to users of critical pollution monitoring systems.

The company has grown to become one of the largest suppliers of pollution monitoring solutions in the UK.


Our Staff

Ensuring our clients comply with pollution monitoring legislation requires us to have staff trained to the highest levels in a variety of disciplines. The team includes engineers that are factory trained and are calibration experts as well as qualified data interpreters and auditing specialists.

Each of our engineers has regular training to update their skills and product knowledge.


To provide the engineers of the future, ESU1 in partnership with Newbury College has an active apprenticeship scheme that is one of the most rigorous in the industry.
