What Herve Thermique does

Hervé Thermique is a French multi-technical building services company founded in 1972 and headquartered in Joué-lès-Tours. It is the historical energy services subsidiary of Groupe Hervé, a diversified family-owned industrial group. The company delivers five core competencies — HVAC engineering (génie climatique), electrical engineering (génie électrique), energy performance, renewable energies (geothermal, photovoltaic), and pool-water treatment — through two main operational vehicles: Installation & Travaux (project-based construction and design-build) and Multi-services & Maintenance (recurring multi-technical maintenance contracts).

The company operates a dense network of approximately 90 local agencies across France plus subsidiaries in Belgium, Luxembourg, Portugal, Morocco, Switzerland, and Mauritius, employing more than 4,000 specialists. It manages technical installations across roughly 28,000 customer sites covering 35 million m². Notable enterprise clients include Center Parcs (4 parks), Kingfisher (Brico Dépôt, Castorama), Airbus, and Olympic Aquatics Center Saint-Denis; the public segment includes schools, sports facilities, and municipal pools. Digital infrastructure includes the Portail Partenaire web/mobile client portal for tracking interventions and a LoRaWAN-based smart water monitoring deployment (via Alerteo partnership) on 60 Brico Dépôt stores.

The revenue model blends one-time project revenue (installation works, design-build contracts such as the Thérèse et Jeanne Brulé CREM) with recurring multi-year maintenance contracts (frequently 12-year exploitation terms, e.g., Center Parcs renewals). Pricing is negotiated per project; no public pricing exists. Distribution is entirely direct — no third-party resellers — with agency managers acting as field sales and account managers in their respective territories. Marketing relies on direct sales, employer branding, and earned media (Great Place to Work, Les Echos rankings). FY2025 revenue reached €532 million, up from €340 million in 2015.
