What Forecastle does

Gaillard Groupe (legally SAS GAILLARD) is a French private limited company headquartered in Les Herbiers, Vendée, that designs, installs, and maintains electrical, thermal, and energy systems for industrial and commercial buildings. Founded in 1961 by Daniel Gaillard, the firm shifted to a B2B focus in 1976 and today operates three integrated service lines: Electrical Installations (power distribution, transformer stations, custom electrical cabinets, lighting, IT networks, security), Thermal Installations (HVAC, heating, plumbing, air treatment, fluid distribution), and Energy Installations (GTB/GTC centralized building management, photovoltaic solar, IRVE-certified EV charging, backup generators). It holds three national certifications — Qualifelec, IRVE P1–P2–P3, and QualiPV — that collectively authorize it to design, install, and maintain the full spectrum of regulated electrical, EV charging, and photovoltaic work.

The company employs approximately 100–120 collaborators and serves four primary verticals — Industry, Grande Distribution (large retail), Agroalimentaire (Food & Beverage), and Collectivités (public sector) — through a dedicated account-manager (chargé d'affaires) model that covers the full project lifecycle from budget study through design, execution, technical follow-up, and maintenance. Technology is anchored in design/simulation tools (AutoCAD, Dialux, Revit, Caneco) and a proprietary GTB/GTC platform that unifies HVAC, lighting, security, energy production, and consumption monitoring under a single supervisory interface; integrations with photovoltaic and EV charging assets are included. Recurring revenue is generated through maintenance contracts and a 24/7 electrical emergency service, while one-time project revenue dominates the mix. Customers include Fleury Michon, K-Line, Puy du Fou, Groupe Dubreuil, Coopérative U, La Boulangère, Le Roy Logistique, Socopa, Charal, and Duplex Metal — collectively pointing to a diversified mid-market and enterprise book across France with regional concentration in Vendée, Loire-Atlantique, Deux-Sèvres, and Charente-Maritime.

Ownership transitioned in 2023 via a management buyout: founder-family successor Laurent Gaillard ceded his shares to the three current co-gérants — Gaëtan Audureau and Olivier Chiron (electricity division) and Alain Boureau (thermal division / SITEC). The group also operates the wholly-owned subsidiary SITEC, acquired in 2008. Revenue is not publicly disclosed; the firm states 1,500+ projects delivered per year, 250 EV charging stations installed cumulatively, 2,000 MWh/year of energy under management, 600+ thermal-services clients, and 150 air-conditioning units installed.

Direct peers

• SPIE: France-listed European leader in multi-technical building services (electrical, HVAC, energy) for industrial, commercial and public-sector clients. SPIE's French electrical/HVAC contracting business directly competes with Gaillard's integrated installation and maintenance offer, and its regional agencies increasingly bid against Gaillard in western France.
• SNEF: Marseille-headquartered electrical and multi-technical contractor operating across France in industry, energy, infrastructure and tertiary. SNEF's scope (electrical installations, instrumentation, maintenance, EV/solar) and its family/MBO-style governance profile make it one of the closest scale comparables to Gaillard among national independents.
• Eiffage Énergie Systèmes: Energy and electrical systems arm of the Eiffage group, providing turnkey electrical installations, HVAC, smart-building GTB and EV charging for industrial and tertiary customers. Overlaps almost perfectly with Gaillard's Électricité/Thermique/Énergie triad and competes at the same project scale as well as in regional tenders.
• Bouygues Energies & Services: Multi-energy services subsidiary of Bouygues covering electrical works, HVAC, smart-building management, EV charging and renewable installations for public and private clients. Its offering maps directly to Gaillard's three product lines and represents one of the major national competitors for large enterprise retrofit programmes.
• Fayat Énergie Services: Energy-services branch of the Fayat group delivering electrical installations, HVAC, high-voltage works and renewable energy to industrial and tertiary clients across France. Comparable in technical breadth and customer types to Gaillard, and an active bidder for the same regional tertiary and industrial projects.
• ENGIE Solutions: ENGIE's French B2B services arm (combining legacy Ineo, Axima and Cofely) delivering electrical contracting, HVAC, building automation, EV charging and energy efficiency to industrial and tertiary customers. Competes head-on with Gaillard for integrated electrical+thermal+energy tenders, particularly in the food-and-retail verticals.
• Equans: Multi-technical services group spun out of Bouygues covering electrical, HVAC, smart-building, energy efficiency and EV infrastructure for industrial, commercial and public-sector clients. Its integrated 'one-stop-shop' positioning is functionally identical to Gaillard's value proposition, just at significantly larger scale.
• Cegelec: Vinci-energies subsidiary specialised in electrical engineering, HVAC and automation for industrial, infrastructure and tertiary buildings. Cegelec's electrical + climate-control offer and regional agency footprint mirror Gaillard's integrated model, making it a direct comparator on mid-size enterprise projects.

Regional players

• Soprema Énergies: Energy and renewable-energy arm of the Soprema roofing/construction group delivering photovoltaic installations and energy services to industrial and tertiary customers, primarily in eastern and northern France. Comparable because of its PV/IRVE/QualiPV positioning and emphasis on B2B solar plus auxiliary systems — similar to Gaillard's renewable-energy practice.

Broad incumbents

• VINCI Facilities: Facility-management subsidiary of Vinci Energies covering multi-technical maintenance and small-project works for corporate real estate portfolios. Although primarily an FM operator rather than an installer, it overlaps with Gaillard's maintenance/SAV book for enterprise clients and is increasingly bundling energy-transition retrofit work.
