What Longevity Partners does

Longevity Partners is a global sustainability advisory firm headquartered in London, United Kingdom, founded in 2015. The firm employs 120+ sustainability experts and serves 140+ clients across all major real asset classes through wholly-owned regional entities in London, Paris, Amsterdam, Munich, Milan, Austin, and Tokyo, with additional operating presence in New York, Helsinki, and Madrid. Its clients are institutional real estate investors, fund managers, developers, and occupiers, with projects spanning 45+ countries; named enterprise relationships include Tristan Capital Partners, Swiss Life, Greystar, Iron Mountain, Covivo, Realterm, and PATRIZIA, several of which date back to 2021-2022.

The firm's service portfolio is organised across five interlocking modules: Strategy & Transformation, Risk & Resilience, Performance & Optimisation, Design & Delivery, and Sustainability Due Diligence, supported by dedicated offerings in green building certifications (BREEAM, LEED, WELL), policy and regulatory advisory, climate resilience, and GRESB-aligned data and reporting. In June 2021, the company extended into renewable energy via the Longevity Power sub-brand. Underlying technology includes a proprietary SaaS certification platform for evidence collection and real-time progress tracking across BREEAM and LEED schemes, plus a CRREM-based climate risk modelling tool that quantifies asset stranding dates and upgrade costs against a 1.5°C pathway. Longevity Partners operates the largest BREEAM In-Use assessor team globally, with 51 licensed professionals holding an estimated 14% global market share and overseeing 2,400+ active certifications.

Revenue is generated through project-based professional services engagements with enterprise clients, with pricing not publicly disclosed. The go-to-market combines direct enterprise sales through senior consultants, regional office coverage, and referral-driven demand anchored in multi-year client relationships. In October 2024, the firm received strategic growth investment from Leon Capital and Nuveen's Private Equity Impact Strategy, supporting continued expansion of headcount, geographic footprint, and technology-enabled service delivery.
