Groupe Long

What Groupe Long does

Groupe Long is a privately-held, family-owned French energy services group founded in 1931 and headquartered in La Varenne (Val-de-Marne). It operates through three core subsidiaries: LONG CHAUFFAGE for boiler installation, maintenance, and repair; LONG ÉNERGIES for fuel and combustible delivery; and VAN FROID (acquired 2020) for heat pump and air conditioning services. A fourth entity, LEVERGER Combustibles Liquides (acquired 2023), is integrated into the fuel delivery operations. The group serves both B2C individual homeowners (pavillons) and B2B collective-building clients (syndicates and property managers) across Paris and south-east Île-de-France.

The technical foundation rests on certified gas and condensation-boiler work (Viessmann equipment including Vitodens 200 boilers and Vitotronic 100/300 cascade regulation systems), heat pump and air conditioning installations via VAN FROID, and an owned logistics fleet of 12-15 fuel delivery trucks supported by a depot in Saint-Maur-des-Fossés. Mandatory certifications (Qualibat, Qualigaz, Professionnel Gaz, RGE) anchor eligibility for regulated maintenance work and for public subsidy schemes such as MaPrimeRénov and CEE certificates. The product portfolio has expanded beyond traditional heating into renewable-adjacent offerings, including HVO biofuel distribution (2024), AdBlue delivery (2026), solar panel installation for copropriétés, and chimney sweeping.

The revenue model blends professional services (installation, repair, chimney sweeping), recurring subscription-style maintenance contracts (P1-P4 regimes for collective boiler rooms), transactional fuel delivery (fioul, wood, pellets, AdBlue, HVO), and one-off renovation projects. Pricing is unit-based for technician labor and travel (€93-€186/hour HT) and multi-year contract-based for collective-building maintenance. The customer mix is long-tail: 705+ verified Google reviews, documented individual client relationships exceeding 42 years, and no concentrated enterprise anchor contracts. GTM combines field-based account managers (chargés d'affaires) for B2B syndicates, direct-to-consumer online ordering and payment (SystemPay) for fuel, and content marketing via website, newsletter, and social channels. The group has no external institutional capital and continues to operate as an independent family enterprise.

Broad incumbents

• SPIE: European multi-technical services group providing HVAC, heating, and energy efficiency services for buildings. Overlaps with Groupe Long's collective-building and commercial HVAC work but operates across multiple geographies and at enterprise scale.
• Saur: French water and environmental services company with adjacent heating and energy services for collective buildings. Comparable in regulated utility-style service delivery and collective building infrastructure, though primarily water-focused.
• Veolia: Global environmental services group with French district heating networks and building energy services. Overlaps with Groupe Long's collective-building heating services but at industrial scale with utility-grade infrastructure.
• Engie Home Services: Subsidiary of Engie providing residential heating, cooling, and plumbing services across France. Directly comparable service portfolio (boiler maintenance, energy renovation, multi-year contracts) but operates at national scale with institutional backing, contrasted with Groupe Long's regional Île-de-France focus.
• Eiffage Énergie Systèmes: Division of Eiffage providing electrical, HVAC, and energy services across France. Comparable in collective-building HVAC and energy renovation offerings, part of a much larger construction group with diversified capabilities.
• Dalkia: EDF subsidiary operating heating networks and collective-building energy services across France. Comparable in collective-boiler-room P1/P4 service contracts and energy efficiency offerings, but at vastly larger scale and with utility parent backing.

Direct peers

• Proxiserve: French multi-technical services firm focused on residential heating, individual housing, and collective buildings. Operates heating services, boiler maintenance contracts, and energy renovation—closely aligned with Groupe Long's LONG CHAUFFAGE and VAN FROID offerings.
• Idex: French energy services company specializing in heating networks, HVAC, and energy efficiency for residential and commercial customers. Closely comparable in service mix (collective building heating, individual residential) and mid-market positioning, with stronger national footprint.
• HomeServe: French home services provider offering heating, plumbing, and electrical subscription contracts to individual homeowners. Directly comparable to Groupe Long's individual residential recurring service contracts (P1/P2 type) and emergency repair model.

Regional players

• Brunel Énergies: Regional French HVAC and energy services firm offering heating, climate control, and fuel distribution. Comparable in service mix (heating, HVAC, fuel) but operating in different regional markets, providing a useful regional benchmark for Groupe Long's Île-de-France model.
