We are delighted to have advised Carnstone Partners Limited on their sale to SLR

Carnstone is market-leading sustainability management consultancy, delivering bespoke impactful ESG strategic advice to the C-suites of their blue-chip customer base. Carnstone’s core areas of expertise include climate change, biodiversity, human rights and response to rising inequality.

Carnstone’s founding team first came together in 2003, giving them unrivalled heritage and time in the market. Their unique collaborative approach allows them to cultivate long-standing client relationships.

A key differentiator is Carnstone’s ability to convene and expand multi-client projects (MCPs), where they facilitate discussion and action within sector-led forums in industries such as pharma, media, chemicals and publishing.

Our corporate finance and tax teams supported the business in preparing to go to market. We ran a competitive, dual track process which resulted in an efficient and competitive marketing process ably supported by our transaction tax team.

 We managed a number of interested parties from across the globe. To the delight of the shareholders we secured a deal solution that met all their needs. SLR provides a fantastic strategic and cultural fit, a brilliant home for Carnstone’s MCPs and significant ongoing roles and opportunities for key Carnstone management and employees.


However experienced you are as a management team, the process of taking your precious company to market is complex, daunting and deeply personal. The Grant Thornton team quickly became invaluable providers, not just of first-rate practical help (their processes are efficient and effective) but also moral support and encouragement. They immediately understood what mattered to us and were lovely to work with. Even at the tricky points, we had fun.

Simon Hodgson Managing Director, Carnstone Partners Limited
