ABOUT US
Passion for
electrical work
who are we?
Kostelac Electrical Services Ltd. has developed through knowledge, experience, and continuous investment in quality. Our story began in 2001 with the establishment of a workshop aimed at providing professional electrical installation services. In 2005, the business expanded by forming a limited liability company based in Ozalj, and in 2018, with the move to a new location at Zagrebačka 15, we created further conditions for continued growth and development.
From the beginning until today, we have adhered to the same principles: reliability, expertise, and a professional relationship with our clients.
