Longevity Partners Limited

Founded in 2015 and based in London, UK, Longevity Partners Limited specializes in sustainability consultancy. The company was founded by its CEO, Étienne Cadestin. In October 2024, Leon Capital and Nuveen acquired Longevity Partners Limited from Long Harbour.   Longevity Partners engages in multidisciplinary energy and sustainability consultancy, providing strategic guidance, compliance support, and solutions to businesses across various sectors.

The firm’s core offerings include sustainability consultancy services, net-zero carbon strategies, environmental audits, energy efficiency assessments, and green building certifications. The company partners with property investors, developers, and occupiers to enhance competitiveness, improve revenues, and address the evolving demands of sustainable practices. Longevity Partners operates in key geographical markets, including the UK, Europe (notably France, Germany, the Netherlands, and Italy), the United States, and Asia (including Japan). Their services have been instrumental for clients ranging from large commercial property companies to financial institutions, collectively aiming to achieve a low-carbon economy.

Longevity Partners generates revenue through a structured model that incorporates consultancy fees for their various services and ongoing partnerships with clients. Transactions typically involve B2B consultancy agreements, where clients engage Longevity Partners for their expertise in sustainability and compliance tailored to specific projects. The October 2024 acquisition enables Longevity Partners to expand resources and enhance strategic capabilities.
