The EUSR CAT 1 Locating Utility Services (HSG 47) course helps workers safely locate and identify underground utilities before any digging starts. It is considered the crème da le creme of courses within this subject.

The EUSR (Energy & Utility Skills Register) CAT 1 Locating Utility Services course teaches participants how to use tools and techniques to locate underground utilities and advance their knowledge around the wider principles of Safe Systems of Work that are implemented. The goal is to avoid accidents and ensure safe digging practices.


Who are EUSR (Energy & Utility Skills Register)?

The Energy & Utility Skills Register (EUSR) is the online register of training and skills for the energy and utilities industries. Individuals that have undertaken an EUSR training and/or assessment on one of our schemes have these recorded against their EUSR registration; we also sometimes record qualifications and authorisations.
