SEPIC and the Roger Delattre group are joining forces to accelerate the energy renovation of territories

This alliance, formalized in July 2025, brings together two historic and family-owned companies sharing strong values: local roots, a field culture and a commitment to sustainable housing.

This strategic partnership allows SEPIC to maintain its autonomy, management team, and locations, while benefiting from the support and resources of a strong group. The objective: to secure its development, pool expertise, and offer its clients—project owners, architects, and engineering firms—more comprehensive and tailored solutions, guaranteeing quality, performance, and satisfaction on every project.

According to Vincent Michalak, president of SEPIC: “This partnership is above all a story of trust. With the Roger Delattre group, we have found a solid and people-oriented partner who understands our business and our values. Together, we are giving SEPIC the means to pursue its development with confidence and ambition, while strengthening the prospects for our clients and partners.”

A dynamic of growth and innovation

This alliance also opens up concrete prospects for growth and innovation: increased investment capacity, development of technical solutions, and team strengthening. It will enable SEPIC to carry out ambitious, tailor-made projects while consolidating its leading role within the local economic fabric of Hauts-de-France and Normandy.

According to Bertrand Crépin, president of the Roger Delattre group: “Our vision is based on the strength of the collective. With SEPIC, we are welcoming a company that shares our family DNA, our technical standards, and a strong local presence. This is a long-term partnership that will allow us to meet the challenges of the sector and build together a more sustainable and efficient building.”
