Recent moves6 records

Broad incumbents

• Vinci Facilities: Facility management arm of Vinci providing HVAC maintenance, energy optimization, and technical services to public and private clients. Competes for the same HLM, public-sector, and commercial maintenance contracts as ERITHERM but at multi-site national scale.
• SPIE: Major French multi-technical services group providing HVAC, electrical, and facility management across France and Europe. Overlaps with ERITHERM on commercial/industrial HVAC installation, maintenance, and renovation contracts, but operates at much greater scale with national footprint.
• Bouygues Energies & Services: Subsidiary of Bouygues Construction providing multi-technical building services including HVAC, energy, and facilities management. Competes for the same enterprise and public-sector HVAC contracts ERITHERM targets, particularly in Île-de-France.
• Dalkia (EDF group): EDF subsidiary specializing in district heating networks, geothermal energy, and HVAC services for buildings and industry. The closest large-scale peer to ERITHERM's geothermal/Dogger aquifer and urban heating network specialty, though Dalkia operates at national scale.
• Eiffage Énergie Systèmes: Division of Eiffage providing electrical, HVAC, and energy services for industrial, tertiary, and public-sector clients across France. Directly comparable on HVAC installation/maintenance, including geothermal and urban heating networks in Île-de-France.
• ENGIE Solutions: French facilities management and multi-technical services arm of ENGIE, covering HVAC, energy, and building services for enterprise and public-sector clients. Comparable because it directly competes for the same CVC maintenance and energy-management contracts ERITHERM serves, but at national scale and across many other adjacent services.
• EIFFAGE / GTM Bâtiment (Île-de-France HVAC subsidiaries): Eiffage's regional HVAC and plumbing subsidiaries operating across Île-de-France. Comparable to ERITHERM on construction and maintenance of CVC systems for residential, commercial, and public-sector buildings.

Others

• CPCU (Compagnie Parisienne de Chauffage Urbain): Paris district heating network operator (part of ENGIE Solutions). Adjacent rather than directly competitive — ERITHERM explicitly references CPCU qualification and participates in CPCU urban heating network extensions, making CPCU both a partner/qualification body and an adjacent infrastructure player.

Direct peers

• Hervé Thermique: French HVAC SME focused on commercial, industrial, and residential heating/cooling installation and maintenance with a strong regional footprint. The most direct comparable by size and service mix to ERITHERM, including multi-site contracting and 24/7 service offerings.
• SNEF: Independent French multi-technical services group covering HVAC, electrical, and maintenance across commercial and industrial markets. Comparable to ERITHERM on HVAC service contracts and energy management, with somewhat larger scale and broader geographic reach.
