What Orbis Advisory does

Orbis Advisory is a London-based boutique sustainability consultancy founded in 2017, focused on helping enterprise and mid-market clients design and execute sustainability strategies across five service lines: Strategy and Implementation, Measurement and Target-Setting, Compliance and Frameworks, Risk Management, and Sustainable Finance. The firm primarily serves real estate companies, private equity firms, and financial institutions, with secondary work across technology, communications, facilities management, banking, and education. Named engagements include CSRD roadmap delivery for Big Yellow Group, CSRD/EU Taxonomy advisory for SEGRO, decarbonisation roadmaps for Excellerate Services, multi-year ESG support for T&P Group, SBTi alignment for Starling Bank, and Scope 3 methodology review for WPP — signalling FTSE-grade and large-cap mid-market client work.

The company's core technology comprises three proprietary assets: a CDP Score Check Tool, a GRESB Pre-Assessment Score Check Tool, and an ESG Regulatory Portal (developed with Orbis ESG Technologies and supported by Barclays Eagle Labs and Sustainable Ventures). The most strategically significant non-service asset is the bi-annual Private Equity Sustainability Index, now in its fourth edition (2025), which benchmarks 81 mid-market PE firms on ESG integration and functions as a recurring thought-leadership engine.

Orbis Advisory monetises through bespoke consulting engagements sold on a likely project/retainer basis via direct, relationship-driven sales. With a team of 1–10 employees and no public pricing, fees are quote-based and tailored. Go-to-market is anchored on thought-leadership content, webinars/panel events (e.g., the PE Index webinars), an email newsletter, and client referrals — supported by industry recognition including Real Deals ESG Awards finalist status and Good Business Charter accreditation.
