Rathbone Greenbank

What Rathbone Greenbank does

Rathbone Greenbank (legal name: Greenbank Investments) is a UK-based sustainable and ethical investment management firm operating as a specialist subsidiary within the Rathbones Group. Founded in the early 2000s and headquartered at 30 Gresham Street, London, the firm positions itself as one of the longest-tenured teams in UK sustainable investment, with over 20 years of experience in ethical and ESG-integrated portfolio management.

The firm builds bespoke portfolios that align client capital with specific environmental, social, and governance values. Its investment process combines proprietary minimum-standards screening with broader ESG analysis, supported by active stewardship and engagement with portfolio companies on sustainability and governance issues. Educational and thought-leadership assets — including the annual Rathbones Responsible Investment Summit, the Investor Day thematic series, the Green Shoots webinar programme, the Engagement in Action hub, and Greenbank Publications — reinforce both client engagement and category authority.

Rathbone Greenbank serves a diversified UK client base of high-net-worth individuals, families, trusts, charitable organisations, financial advisers, and professional intermediaries (lawyers, accountants, consultants). Revenue is generated through asset-under-management-based management fees on bespoke portfolios, with a relationship-driven, sales-led go-to-market model that relies on direct client coverage and intermediary referrals. The firm operates exclusively in the United Kingdom and is not separately capitalised via external funding.
