EUSR Category 1 Locate Utility Services Course

Underground utility networks don't reveal themselves, and getting a detection survey wrong can lead to serious injury, costly damage and lengthy site delays. The EUSR Category 1 Locate Utility Services Course gives anyone working near buried services the knowledge and hands-on skills needed to locate them safely, using industry-recognised equipment and approved detection methods.


Also known as HSG47 or Cat & Genny training, this safety-critical course moves well beyond the classroom, combining theory with genuinely practical assessment that meets both EUSR and National Occupational Standards. It forms part of the wider EUSR training framework, recognised across the energy and utilities sector for maintaining high standards of competence and workplace performance. For those wanting a shorter, more focused introduction to detection equipment before committing to the full EUSR qualification, the CAT & Genny Cable Avoidance Testing Course covers similar ground at a more basic level.


Because safe excavation follows on so directly from accurate detection, this course pairs naturally with the EUSR Category 2 Implementing Safe Excavating Practices Course for anyone whose role covers both stages of the process. Delegates carrying out risk assessments as part of their detection work will also find the Risk Assessment Online Course a useful companion, while general site-based PPE Awareness Training complements the specialist equipment covered here well. Anyone whose detection work also involves working at height should keep Working at Height Training in mind too.


Delegates must have a basic understanding of both spoken and written English, and must bring photographic identification such as a passport or driving licence. Delegates must also bring the required PPE for the practical learning and assessment, including a hard hat, high-vis jacket, safety boots, safety goggles, steel cap wellies in winter, and clean clothes and shoes for classroom learning.
