The RGE (Reconnu Garant de l’Environnement) certification is awarded to construction companies that specialize in energy-efficient renovations and the installation of equipment that uses renewable energy. It attests to the professionals’ expertise, ongoing training, and compliance with current standards, thereby guaranteeing the quality of the work performed for individuals and businesses.
Hiring an RGE-certified professional is mandatory to qualify for major government grants such as the Heat Fund and CEE grants. Without this certification, the work does not qualify for any subsidies, which can significantly impact project financing.

RGE-certified companies are subject to random inspections and transparency requirements, which help minimize the risk of fraud or substandard work.
