The benefits of engaging ON Engineers for the Servicing of Electrical Installations are as follows:-
- Maintenance of high voltage apparatus in accordance with Energy Market Authority's guidelines and manufacturers’ recommendations.
- Safe and effective operation of an electrical system with minimum risk of breakdown and consequent interruption of power supply.
- A comprehensive written technical report providing critical data and recommendations after maintenance servicing work, allowing management to have a better understanding of the condition of their electrical system and the areas that require their attention.
- Advisory and actual services in follow-ups to the servicing, such as repairs and replacements.
- Besides our pre-servicing, servicing and post-servicing activities, we value-add by offering online storage of servicing reports through our Online File Management System so that they are able to easily access these reports 24/7.
- Follow-up with our clients to strengthen and maintain their servicing regime.
