But growth had stayed by its side as Drainage Division was added into the line in 1987.

In 1990, Electrolux Services acquired Thomas Cowan and Cleaning Division was added to complement existing services.

When Environmental Services (ESGO)  acquired all AB Electrolux' s cleaning and commercial service activities in Asia and the Middle East (03 April 1992), it further strengthens the mission of Thomas Cowan to provide comprehensive " Package Deal" services i.e. Cleaning, Pest Control and Drainage Works.

Now under the new ownership of ISS A/S, the company name was changed to ISS Thomas Cowan Sdn Bhd.  We are the only company offering "Package Deal" and ISS "Facility Sevices" in Brunei.   

Our clientele includes Royal Palaces and Guest Houses, hotels restaurants, department stores, banks, staff houses, supermarkets, offices, government entities and residential houses.
