Assemblin strengthens green technology offering with acquisition of NGL Energientreprenad AB

Assemblin has acquired energy and water optimisation company NGL Energientreprenad AB (“NGLEE”), with annual sales of approximately SEK 35 million and 22 employees.

NGLEE offers services predominantly in energy optimisation, mainly by installing and fine-tuning heating/hot water circulation systems and tap water optimisation throughout the country. These measures lead to greener properties by reducing their environmental impact, optimising operating costs and giving property owners a greener footprint, as well as improving residents’ indoor environment.

“Demand for these resource and energy saving measure is high and NGLEE is one of the best players in the market. We see multiple opportunities for increased collaboration with Assemblin’s installation organisation, benefiting both parties. With this acquisition, we also strengthen our position in green technology – one of our strategic growth areas,” says Andreas Aristiadis, President and Business Area Manager, Assemblin H&S.

NGLEE’s customers include several property owners with large rental housing portfolios across Sweden as well as non-profit housing companies and tenant-owner associations. Customers include Victoriahem, Bostadsbolaget, Rikshem and SBC.

“We have experienced rapid growth and see continued expansion opportunities. With this strategic merger, we further strengthen our organisation and market position, whilst maintaining the core expertise our customers are familiar with. By taking NGLEE to the next level as part of Assemblin, we know we will provide even better support to our customers,” says Benny Lieberth, CEO and co-owner of NGLEE.
