Cegelec Clim Ouest Nantes

What Cegelec Clim Ouest Nantes does

Cegelec Clim Ouest Nantes is one of three coordinated regional entities (Brest, Nantes, Rennes) operating under Cegelec Portes de Bretagne, a wholly-owned SAS subsidiary of VINCI Energies within the publicly listed VINCI Group. Headquartered at Carquefou in Pays de la Loire, the Nantes office serves the Loire-Atlantique and Maine-et-Loire departments. The group designs, installs, commissions, and maintains HVAC (heating, ventilation, air conditioning), plumbing, fire safety systems, and industrial piping for new construction and rehabilitation projects. Customers include healthcare providers (CHU de Brest, Hôpital Morvan, Clinique Pasteur), educational institutions (Lycée de la Joliverie, Lycée de Pontchâteau), transportation infrastructure (Rennes Metro Line B, Gare SNCF), government facilities (Cité Administrative de Nantes, IPEV, Labocea), defense (Thalès), hospitality (Valdys Resort, Casino Dinard), energy (RTE), and industrial/technology clients (Keopsys, Rivazur Cakes).

The technology foundation combines conventional mechanical HVAC engineering with Building Information Modeling (BIM) expertise for 3D digital modeling of complex construction interfaces, and the NOOCO life cycle analysis (ACV) software to quantify environmental impact for client carbon footprint assessments. Each regional entity maintains its own in-house engineering studies bureau (bureau d'études), and the group holds multiple Qualibat specialty certifications (5113, 5121, 5213, 5232, 5251, 5252, 5312, 5313, 5322) covering BIM plumbing, gas/oil heating, heat pumps, cleanroom air treatment, and mechanical smoke extraction, alongside ISO 9001:2015 quality certification and refrigerant handling attestation. Specialized technical capabilities include cleanroom environments up to ISO 5 classification for healthcare and laboratory applications, energy renovation work including heat pump replacements, and occupied-site retrofit execution.

The business operates an enterprise field sales model with project-based, quote-driven pricing and multi-year contracts. Revenue comes from two streams: project-based HVAC/plumbing/fire safety/industrial piping installation (professional services) and ongoing maintenance of installed systems (subscription/recurring). The group employs 107 people across the three entities and reported €27 million in 2024 revenue. Distribution is direct, with no channel partners; lead generation relies on direct client relationships, the corporate website, regional LinkedIn pages, referrals, and the VINCI Energies brand. Geographic focus is entirely on Brittany and the Pays de la Loire region of western France.

Broad incumbents

• VINCI Facilities: Sister VINCI Energies subsidiary focused on building facility management and maintenance rather than new-build installation. Not a direct competitor on installation projects but adjacent within the same parent, with shared client base and potential cross-sell/competition for maintenance contracts.
