Electrical Licensing Service


Our company’s main strength lies in the area of providing licensing services for electrical installations. Growing and learning with our clients, we have continually improved our service and technical expertise.

We are now the industry’s largest electrical licensing service provider, overseeing the electrical safety of major installations across all industries, such as commercial and retail, data centre, telecommunications, petrochemical, healthcare, hospitality, industrial and government services.

Through a mindset of continual improvement, we have harnessed proven technology, delivering instantaneous inspection reports for our client, continuing to cater to the ever-growing needs of our clients and still leading the industry in this area.

Our Inspections Process and Reports

Our team use mobile devices to carry out our licensing inspection duties. Through the use of mobile devices, we are able to capture, store and analyse our clients’ electrical installation data from our inspections, enabling us to add value by providing timelier and more accurate advice to our clients.

Our inspections process involves the generation of a digital draft inspection report for our clients immediately after each inspection. This enables our clients to achieve faster follow-ups should any action be needed for their electrical installation. A finalised copy will then be sent to our clients within five working days after the inspection.

The electrical installation inspection report from ON Engineers are clear, accurate, detailed, and timely so that clients are able to make more informed decisions. A “Report and Defect Summary” with site photographs, descriptions and remedial advice, enable our clients to be updated on the on-site conditions and actions needed.

With the availability of such data, we produce digital quarterly inspection summary reports for our larger clients to categorize and group the results of the clients’ various electrical installations or their tenants in a single report. This is done to cater to our clients’ needs as this reduces the amount of paperwork and manual work they need to go through and also helps to highlight the areas that may require their attention.

The storing of digital copies of the inspection reports enables instant retrieval 24/7 and document filing completeness while saving our clients space and resources in managing these reports.

Just another electrical installation inspection report?   ON Engineers takes this to another level with our industry-leading processes and technical capabilities.
