What arbnco Limited does

arbnco Limited is a UK-based private SaaS company that provides an AI-powered platform for commercial real estate decarbonisation, carbon reporting, and ESG compliance. Founded in 2009 and headquartered in Glasgow with a North American office in Plymouth, Michigan, the company sells primarily to UK REITs, investment and property managers, corporate occupiers, and ESG professionals in finance and utilities. The platform is organised around a four-level service approach — Level 1 data access and carbon reporting (offering up to 100% portfolio coverage via proprietary energy identification technology), Level 2 digital consent management for tenant data sharing, Level 3 decarbonisation strategy with portfolio-wide analytics, and Level 4 calibrated energy modelling that produces costed retrofit recommendations in hours rather than weeks of manual engineering audits.

The product portfolio comprises a unified core platform and eight modules: Carbon Reporting, Decarbonisation, EPC Risk Management, Facilities Management, Financed Emissions, Utilities, Consent Management, and Decarbonisation Action Plan (Calibrated Energy Modelling). Underlying technology stacks proprietary energy-consumption identification algorithms, portfolio-wide performance analytics, and calibrated simulation on top of utility-data integrations with partners such as Centrica/British Gas Business and (in development) MOSL. The platform supports compliance with GRESB, TCFD, SECR, and Ofwat reporting frameworks, with named customers spanning over 100 UK companies including JLL, CBRE, PGIM, Nuveen, Legal & General, British Land, Assura, abrdn, Savills Investment Management, M&G Real Estate, Long Harbour, New River REIT, and Centrica.

The commercial model is subscription-based recurring SaaS revenue delivered through an enterprise field-sales motion using discovery sessions, product demos, and quote-based pricing (not publicly disclosed). Distribution relies on direct enterprise sales supplemented by a utility-partnership channel via Centrica/British Gas Business that functions as both a data-access channel and a co-delivery mechanism. The company was founded by current CEO Maureen Eisbrenner and is governed by director Ian Warwick. Recent product launches in 2026 include water consumption data access and GRESB coverage substantiation, with Ofwat's 2026 consultation on centralised water data sharing aligning with the company's roadmap.

Core offering

arbnco provides an AI-powered SaaS platform that helps commercial real estate companies access building energy and water consumption data, manage tenant consent, run carbon reporting, and develop decarbonisation strategies and action plans. The platform uses proprietary data identification and calibrated energy modelling to deliver up to 100% portfolio data coverage without requiring initial tenant engagement, replacing expensive manual audits and digital twins with hours-fast modelling and costed retrofit recommendations.

Product overview

arbnco offers a single unified AI-powered SaaS platform for net-zero and real estate ESG management. The core platform integrates six specialized modules: Carbon Reporting, Decarbonisation, EPC Risk Management, Facilities Management, Financed Emissions, and Utilities. The platform follows a four-level approach: Level 1 provides data access and carbon reporting with up to 100% portfolio coverage; Level 2 offers digital consent management for tenant data sharing; Level 3 delivers decarbonisation strategy with immediate performance analytics and benchmarking; and Level 4 provides calibrated energy modelling for dynamic building simulation and costed retrofit recommendations.

• Schneider Electric EcoStruxure: Schneider Electric's EcoStruxure includes building energy management and decarbonisation tools serving commercial real estate; a broader incumbent that competes with arbnco on building-level energy analytics and retrofit advisory.
• JLL Sustainability Services: JLL is both an arbnco customer and a provider of in-house sustainability and energy advisory services for CRE owners and occupiers; comparable as a competitor in CRE decarbonisation consulting while also being a channel for arbnco.
