Electrical Installation Licence & Safety Training: Complete Compliance Guide

Electrical safety is a critical responsibility for businesses operating commercial, industrial, and other non-domestic premises in Singapore. From understanding whether your installation requires a licence to ensuring employees follow safe working practices, the right approach can help reduce risks, prevent avoidable disruptions, and support regulatory compliance.

However, many businesses are unsure about Electrical Installation Licence requirements, when a Licensed Electrical Worker (LEW) is needed, or what type of Electrical Safety Training employees should receive.

This guide explains the key considerations and practical steps businesses can take to manage electrical licensing and workplace safety more effectively.

What Is an Electrical Installation Licence?

An Electrical Installation Licence is required for certain electrical installations in Singapore. The Energy Market Authority (EMA) licensing scheme is designed to ensure applicable electrical installations are operated and maintained by appropriately licensed electrical workers.

An electrical installation generally includes electrical wiring, fittings, and apparatus used to convey and control electricity within premises.

For non-domestic premises, an Electrical Installation Licence is generally required when the approved load exceeds 45 kVA. Electrical installations used for certain hazardous trades may also require a licence regardless of approved load.

Because requirements depend on the type and circumstances of the installation, businesses should assess their specific situation before deciding whether a licence is required.

Why Is an Electrical Installation Licence Important?

Electrical systems are essential for everyday business operations, but electrical faults, poor maintenance, or unsafe working practices can create serious safety and operational risks.

The licensing framework helps ensure that applicable installations are placed under the responsibility of a suitably qualified Licensed Electrical Worker.

Depending on the installation and LEW licence class, the worker may carry out or oversee activities such as:

• Electrical installation work
• Inspection and testing
• Maintenance
• Operation
• Repair
• Certification
• Safety-related electrical assessments

EMA states that electrical work should be carried out or supervised by a licensed electrical worker of the appropriate class.

Do You Need an Electrical Installation Licence?

This is one of the first questions a business should answer.

You may need to consider an Electrical Installation Licence if your premises:

• Is used for non-domestic purposes
• Has an approved electrical load exceeding 45 kVA
• Is used for a hazardous trade covered by the licensing requirements
• Has an electrical installation that falls under EMA's licensing scheme
• Requires ongoing inspection and certification by an appropriate LEW

For example, EMA specifies that non-domestic electrical installations with an approved load exceeding 45 kVA require licensing. Certain hazardous-trade installations are also subject to licensing regardless of approved load.

If you are unsure whether your installation qualifies, obtaining professional advice before starting an application can help you avoid unnecessary delays or compliance issues.

What Is Electrical Safety Training?

Electrical Safety Training helps employees and supervisors understand electrical hazards and follow appropriate safe-working procedures.

Employees who work with or around electrical equipment may encounter hazards such as:

• Electric shock
• Arc flash
• Electrical fires
• Damaged cables
• Overloaded circuits
• Incorrect isolation
• Unsafe equipment
• Improper use of electrical tools

Training should be relevant to the employee's responsibilities and the risks present at the workplace.

A good training programme can help employees recognise hazards, understand preventive measures, and respond appropriately when an electrical safety issue occurs.

Why Is Electrical Safety Training Important?

Electrical safety is not only the responsibility of the person carrying out electrical work. Employees, supervisors, contractors, and facility teams may all interact with electrical equipment or work near electrical installations.

Effective Electrical Safety Training can help businesses:

• Improve electrical hazard awareness
• Encourage safer working practices
• Reduce avoidable workplace risks
• Improve understanding of electrical procedures
• Support internal safety policies
• Help employees respond appropriately to electrical incidents
• Build a stronger workplace safety culture

Training should also be reviewed when equipment, processes, work areas, or responsibilities change.

Electrical Installation Licence vs Electrical Safety Training

Although these two areas are related, they serve different purposes.

Electrical Installation Licence

The licence relates to the regulatory management of applicable electrical installations. Businesses with installations covered by the licensing scheme must meet the relevant EMA requirements and appoint an appropriate LEW to take charge of the installation.

Electrical Safety Training

Training focuses on helping workers understand electrical hazards and follow safe working procedures.

For a business, having appropriate licensing arrangements and ensuring employees understand electrical safety can provide a more comprehensive approach to managing electrical risks.

Common Electrical Safety & Compliance Problems

1. Uncertainty About Licensing Requirements

Many businesses are unsure whether their electrical load or premises use means an Electrical Installation Licence is required.

The first step is to review the installation type, approved load, premises use, and applicable EMA requirements.

2. Using the Wrong Electrical Worker

Different classes of Licensed Electrical Workers have different authorised scopes.

EMA identifies three main classes: Licensed Electrician, Licensed Electrical Technician, and Licensed Electrical Engineer. Their authorised work depends on factors including approved load and voltage.

3. Incomplete Documentation

Applications and compliance activities may require documents such as a Letter of Appointment, valid electricity account information, and single-line drawings, depending on the application.

Keeping technical and licensing documents organised can make compliance management easier.

4. Insufficient Employee Awareness

Even when an organisation has appropriate electrical systems and professional support, employees may still be exposed to risks if they do not understand safe working procedures.

This is where relevant Electrical Safety Training can make a practical difference.

5. Delaying Inspection or Maintenance

Electrical issues should not be addressed only after equipment fails or an incident occurs.

Regular inspection, testing, and preventive maintenance can help identify potential problems before they become more serious.

How to Manage Electrical Compliance Step by Step

Step 1: Assess Your Installation

Start by identifying the type of electrical installation, approved load, voltage, premises use, and operating conditions.

Step 2: Confirm Licence Requirements

Check whether your installation falls within the applicable EMA Electrical Installation Licence requirements.

Step 3: Appoint an Appropriate LEW

Where required, appoint a Licensed Electrical Worker with the appropriate class to take charge of the installation. EMA requires the appointed LEW to inspect the installation and ensure it is safe to use before submitting the licence application.

Step 4: Review Your Electrical Documentation

Make sure relevant drawings, records, certificates, and other supporting documents are available and up to date.

Step 5: Identify Workplace Electrical Hazards

Review the areas where employees interact with electrical equipment or work near electrical installations.

Step 6: Provide Electrical Safety Training

Train employees according to their roles and the electrical hazards present in the workplace.

Step 7: Schedule Regular Reviews

Electrical safety should be treated as an ongoing process. Review your systems, procedures, training, and documentation whenever there are significant changes.
