What Prox Hydro does

Prox-Hydro is a privately held French company founded in 1953 and headquartered in Marseille, operating as an energy management and environmental services provider for collective residential housing. The company installs, maintains, and remotely reads metering infrastructure across five energy uses — water (cold and hot), heating, cooling, electricity, and indoor air quality (mechanical ventilation) — using radio-based tele-relevé technology that delivers daily consumption data through web-based portals for residents and property managers. Its core service is Individualisation des Frais de Chauffage (IFC), which replaces tantième/surface-based heating cost allocation with per-unit consumption measurement using heat cost allocators and thermal energy meters, complying with French regulatory mandates under RT 2012 (Article 23) and RE 2020.

The company's technology stack combines physical hardware (meters, allocators, ventilation systems) with the ACCES PRO professional platform and an occupant portal for billing, payment, and consumption tracking. Certifications include ISO 9001 version 2015, LNE (Laboratoire National de Métrologie et d'Essais) approval for Vérification de Conformité d'Installation, and RGE Qualibat n°5311 for VMC installation. Through its wholly-owned subsidiary ZEborne, Prox-Hydro has expanded into turnkey electric vehicle charging infrastructure for residential complexes, featuring ADVENIR-certified infrastructure and 100% green electricity billing management.

Prox-Hydro generates recurring subscription revenue across multiple streams: water metering services, IFC contracts priced at 2.5–3.5 EUR TTC per housing unit per month, annual VMC maintenance contracts, RT 2012/RE 2020 compliance solutions, and ZEborne's managed EV charging services. The company targets B2B professional clients including property managers (syndics), social landlords (bailleurs sociaux), and property developers (promoteurs), with individual homeowners served through their building's property manager. Distribution relies on direct sales outreach and regulatory-referral pipelines, with the platform claiming 20% average reduction in building energy consumption and ADEME-cited 15% energy savings per housing unit following IFC installation. Geographic focus is southern France (Provence-Alpes-Côte d'Azur) with a Toulouse billing office.
