Who We Are

Inexma Electrical was founded in August 2003 by Johan Muller.


It was Johan’s vision to grow Inexma into one of the leading electrical contractors in the Western Cape through the employment of experienced staff that shared Johan’s vision of quality service, integrity, innovation and professionalism. Johan realized this vision over the last decade and currently Inexma undoubtedly holds a key leadership position in the Electrical Contracting Industry of the Western Cape.


A decision was taken in 2013 by Johan that Inexma would leverage its experience gained as leading electrical contractor in the Western Cape by extending its operations into Namibia. Inexma Namibia was formed by joining forces with Mr. Ranga Haikali, a well-known and well established Namibian Business Entrepreneur. This company is registered in Namibia, and has significant Namibian shareholding. Some of Inexma’s Key staff members were seconded to the newly formed company and are now permanently based in Windhoek. The decision to form Inexma Namibia immediately met with significant success. The company was quickly appointed as the Electrical Contractor on two significant projects: The UNAM Residence (University of Namibia) project in Windhoek and “The Lady Pohamba Private Hospital” in Windhoek.
