At EMSD, we hold a dual role - delivering professional, reliable and cost effective electrical, mechanical, electronic engineering and building services for government departments and public institutions in Hong Kong, as well as providing a regulatory framework to ensure the safety of the public in a number of electrical, mechanical and gas engineering areas.

In serving our customers, we provide a range of consultancy and value-added engineering and maintenance services to ensure that the many systems that keep Hong Kong up and running continue to do so effectively and efficiently. We serve the airport, hospitals, schools, security forces, transport and highways, port and harbour as well as public recreation and leisure facilities, areas that make up the very fabric of life in Hong Kong.

Within the community, we issue guidelines and Codes of Practice and administer the safety ordinances on the safe use of gas, electricity, lifts and escalators, railways, tramways and amusements rides among others. At the same time, we are actively involved in promoting energy efficiency and the protection of the environment through new services and activities both for our customers and the community, and through our support for the government's environmental initiatives. We are actively involved in the introduction of LPG vehicles for example, and in studies for renewable energy sources in Hong Kong.
