Hsg47 HV Underground Training

HSG47 Training Courses

Working around underground services is one of the highest-risk activities on any construction, utilities, or civil engineering project. Striking buried cables, pipes or other infrastructure can lead to serious injury, costly project delays and major service disruption. High-voltage electricity cables present an especially severe hazard, where even a single mistake can result in life-changing injuries or fatalities. That’s why proper training and certification are essential before anyone begins excavation work.

Comprehensive HSG47 Training Courses

Our HSG47 training courses are designed to give contractors, groundworkers, supervisors and site managers the knowledge and confidence they need to work safely around underground utilities. Based on the guidance outlined in the Health and Safety Executive’s Avoiding Danger from Underground Services (HSG47), these courses explain the correct procedures for locating, identifying and safely working near buried services. Delegates learn how to interpret utility plans, use detection equipment effectively, follow safe digging techniques, and understand the responsibilities required to prevent service strikes.

Practical Knowledge & Real-World Application

By completing our professionally delivered HSG47 courses, your team will gain practical knowledge aligned with industry best practice. Each course focuses on real-world site scenarios, helping operatives understand the dangers of underground electricity, gas, water and telecoms services and how to manage those risks properly. This ensures workers not only understand the theory behind HSG47 guidance but can apply it confidently on site.

Recognised HSG47 Certificates

Successful delegates receive recognised HSG47 certificates, demonstrating that they have been trained in the safe avoidance of underground services in line with HSE guidance. These certificates provide evidence of competence for contractors, principal contractors and project managers who must demonstrate compliance with safety standards on construction and utility projects.

Benefits for Your Organisation

Whether you are training new operatives or refreshing the knowledge of experienced teams, our HSG47 training courses help organisations reduce risk, meet regulatory expectations and promote safer excavation practices across every project. With clear instruction, practical guidance and recognised HSG47 certificates, your workforce will be better equipped to work safely around underground services and avoid the serious consequences of service strikes.

What Our Specialised HSG47 Courses Cover

Our HSG47 training courses are designed to give operatives, supervisors and contractors the practical knowledge needed to safely avoid underground services on site. Based on the guidance outlined in HSG47: Avoiding Danger from Underground Services, these HSG47 courses focus on proven industry methods for planning, locating and safely excavating around buried utilities.

The training combines clear guidance with practical techniques, ensuring delegates gain the confidence required to apply HSG47 best practice in real working environments. Successful completion of the course leads to recognised HSG47 certificates, demonstrating competency in working safely around underground services.

Our courses cover the key principles of safe excavation and service avoidance, including:

Advanced Planning

Learn how to correctly obtain, review and interpret utility drawings and service plans before any excavation begins. Our HSG47 training courses explain how to identify potential underground hazards, assess site conditions and ensure the correct planning procedures are followed in line with HSE guidance.

Emergency Awareness & Response

Understanding what to do if an underground service is struck is a critical part of HSG47 certificate guidance. Delegates learn the correct response procedures, how to protect workers and the public, and how to manage incidents involving electricity cables, gas pipes or other buried infrastructure.

Service Location & Detection Techniques

Our HSG47 courses provide practical instruction on the safe and effective use of detection equipment such as Cable Avoidance Tools (CAT) and signal generators (Genny). Delegates learn how to trace underground utilities, interpret signals accurately and confirm service routes before excavation begins.

Safe Excavation Procedures

Following HSG47 best practice, the course explains how to establish safe digging zones and carry out excavation using appropriate techniques. Delegates learn when to use mechanical excavation, when hand digging is required, and how to work safely once services have been identified.

By completing our professional HSG47 training courses, delegates gain valuable knowledge that helps reduce the risk of service strikes and improves safety across construction, civil engineering and utility projects. The HSG47 certificates awarded at the end of the course provide clear evidence that your workforce has been trained in recognised industry guidance for avoiding underground services.

The Extreme Danger of High Voltage Strikes


A standard utility strike is serious; an HV strike is deadly. Our HSG47 training courses prepare your team members for the unique and devastating risks involved:

Direct contact with HV cables (typically 11kV and above) results in immediate electrocution.

The immense energy released during an HV strike creates an arc flash, which can cause severe, deep tissue burns from heat exceeding 35,000°F and generate an explosive blast that causes physical trauma.

Striking an HV service can cause widespread power outages across local grids, resulting in national level penalties and immense project liability.
