How to Get Certified in High Voltage Safety Training

If you work with electrical systems, completing a High Voltage Course is a key step to staying safe and compliant. High voltage safety training is essential for anyone working with or around equipment that operates at dangerous voltage levels—often found in marine, offshore, industrial, and energy environments.

 

This guide will walk you through the step-by-step process of getting certified, including who needs the training, what the courses involve, and how it can benefit your career.

What Is High Voltage Safety Training?

High voltage refers to electrical systems that operate above 1,000 volts AC or 1,500 volts DC. These systems are common in industrial settings, power plants, offshore facilities, electric vehicles (EVs), and many maritime environments.

 

High voltage safety training teaches workers how to handle these systems safely. Courses typically include both theoretical knowledge and practical skills to ensure you’re prepared for real-world scenarios.

Who Needs This Certification?

You may need high voltage safety certification if you:

 

• Work directly with high voltage systems (e.g., switchgear, transformers, control panels).
• Perform maintenance or testing on high voltage equipment.
• Supervise or manage staff in high-risk electrical environments.
• Are part of a safety team responsible for enforcing electrical safety procedures. 

Employers are also legally responsible for ensuring that their staff are competent and trained to work safely with electricity.

Eligibility Requirements

For most basic high voltage awareness courses, there are no strict entry requirements. These are suitable for managers or staff who do not work hands-on with high voltage systems.

 

However, for more advanced courses—especially those aimed at becoming an “Authorised Person”—you will often need:

 

• Prior experience or qualifications in electrical systems.
• A low-voltage electrical background.
• Familiarity with standard safety practices. 

Always check with the training provider about specific prerequisites before enrolling.

Types of Courses Available

1. High Voltage Awareness Courses

• Duration: 1–2 days
• Focus: Theory only
• Suitable for: Supervisors, safety officers, or non-technical staff
• Covers basic safety principles and the dangers of high voltage

2. Authorised Person (HV Switching) Courses

• Duration: 3–5 days
• Focus: Theory + hands-on practice
• Suitable for: Technicians, electricians, and engineers working directly with HV systems
• Includes safe isolation, switching procedures, risk assessments, and permit-to-work systems

3. Specialist Courses (e.g., for Electric Vehicles)

• Focuses on high voltage safety in electric vehicle technology
• Often part of a Level 2 or Level 3 qualification

What Will You Learn?

Typical course content includes:

 

• Electrical hazards and how they affect the human body
• UK safety laws and regulations (e.g., Electricity at Work Regulations 1989)
• Arc-flash and electric shock prevention
• Safe working distances and approach boundaries
• Correct use of personal protective equipment (PPE)
• Safe isolation and switching procedures
• Permit-to-work and risk assessment protocols
• Emergency response and incident management 

Advanced courses will also involve hands-on training with mock switchboards or actual high voltage equipment.

Assessment and Certification

Most courses end with both a theory test and a practical assessment. You must demonstrate an understanding of the safety principles and show that you can apply them correctly in a controlled setting.

 

Upon successful completion, you’ll receive a certificate of competence or authorisation. Some training providers may issue only an attendance certificate if you do not pass the full assessment.

 

Recognised certifications include those from:

• City & Guilds
• NEBOSH (for health and safety integration)
• TÜV SÜD
• MTCS (Marine Training & Certification Solutions)

How Long Does It Take and What Does It Cost?

• Awareness courses: Usually 1–2 days; cost between £100–£300
• Authorised person courses: Last 3–5 days; cost between £800–£1,500 depending on the provider
• Refresher training: Often required every 3–5 years 

Some providers offer flexible learning through online theory modules, followed by in-person practical training.

Benefits of Getting Certified

Becoming certified in high voltage safety offers several key benefits:

 

• Improved safety – Fewer electrical accidents and safer working environments
• Career development – Qualify for more technical roles in the marine, offshore, energy, and transport sectors
• Regulatory compliance – Ensures both you and your employer meet national safety standards
• Increased employability – Certification is recognised across many industries and countries
