Foundation & early years
Insaver was founded in Lummen in 2012 with the aim of improving the energy efficiency of buildings. Initially, the focus was on energy saving, but our services soon expanded to include the generation and later the storage of energy. This expansion eventually led to a move to Zonhoven.Partnership with Luminus
In 2017, Luminus and Insaver are joining forces, driven by their shared commitment to sustainability. This collaboration transforms Insaver from a local player into a major player on the Belgian market.Reinforcement and expansion
Building on the knowledge and experience gained, Insaver founded its own B2B unit in 2018. The first project is AD Delhaize in Riemst. Insaver is building its own knowledge centre with a view to further innovation. The team continues to grow, leading to a second move to Houthalen in 2019.Integration of Aralt
With the integration of Aralt, the focus on post-installation service is strengthened. The team is being expanded to include in-house technicians, with the focus on improving efficiency and processes. The first steps in the area of charging infrastructure have already been taken.Market leader in Belgium
