ESG Benchmark acquires Asesoria Group Limited

The following statement is issued by Iain Fairbairn on behalf of ESG Benchmark Group Limited.  

27 June 2025, 11.00AM  

ESG Benchmark Group is pleased to announce the acquisition of Asesoria Group Limited. Asesoria Group is an established management consultancy specialising in Governance, Sustainability and Leadership; offering these services to a range of FTSE listed corporates together with other private companies and public sector clients.  

In completing the acquisition, Iain Fairbairn, Managing Director stated “while Asesoria will continue to operate independently this brings together two businesses whose focus is on sustainability and ESG. The core values and mission are to help organisations, irrespective of size, advance their sustainability and adopt responsible business practices; making a positive difference to society and the environment.”   

Fairbairn further added “Together the businesses have a strong, experienced and knowledgeable team and the skill sets of the two teams complement each other very well. We believe this is key to future success particularly as clients increasingly require a broad spectrum of support ranging from governance, value chain due diligence, social value strategies, through carbon emissions calculations to stakeholder reporting. The strength of the team, and the specialists within the business will ensure we can deliver this.” 

Melissa Kittermaster, CEO of Asesoria commented This is an exciting new chapter for Asesoria Group.  I believe ESG Benchmark and Asesoria have the same values and approach to sustainability and share our ambitions for continued growth. I believe this will enable Asesoria to offer a broader range of services to our clients, particularly around supply chain due diligence, sustainability governance and assurance services.  I am looking forward to working with Iain and his team over the coming months to develop a long-term strategy that will benefit both organisations using our combined skills, knowledge and expertise” 

Asesoria will continue to have London offices and this will be complimented with offices located in Bath for the expanded group.  

Iain Fairbairn would like to thank the corporate team at RWK Goodman in Bath for their support during the process, which was performed with professionalism, efficiency and discretion.
