Who are we?

About us

Square Gain was established in 2015 with a mission to accelerate the journey to a low-carbon, sustainable and resilient economy. We do this by helping clients to improve their Environmental, Social and Governance (ESG) performance and climate resilience.

We believe in equality and inclusion and in being 'fair and square'. We also want clients to gain an advantage through an inclusive ESG approach. Hence the name Square Gain.

Experience is the key to success. All our staff and associates have over 20 years of experience in sustainability leadership. We provide clients with the practical knowledge and expertise that this brings and have worked with over 60 clients, from small companies to multinationals, from universities and councils to the NHS.

We focus on supporting our clients in developing in-house skills by embedding ourselves within client teams, and by providing training and e-learning to build capacity and make real progress on carbon reduction, circular economy and wider sustainability.

Our clients

Since establishing itself in 2015, Square Gain has worked with over 60 clients including multinationals, listed companies, and public sector organisations. We continue to work with many of them today.

Our background is in sustainable development, real estate and construction, and many of our clients come from these sectors.

We work with Real Estate Investment Trusts (REITS) and others on sustainability strategy, decarbonisation plans, ESG reporting and more. Buildings form part of the decarbonisation strategies for all of our clients and provide a solid foundation for wider sustainability initiatives.

Our core services

We provide a range of consultancy services, from ESG regulatory advice, to policy and strategy development, operational support and ESG and TCFD (Task Force on Climate-related Financial Disclosures) reporting.

Square Gain provided ESG Board Advisory for UPP and we were very pleased with not only their market knowledge, but also their ability to engage with the whole board and facilitate a very useful discussion.
